Why My House a/C Isn't Cooling Anymore ?

It sounds as if you have a refrigerant leak although it could be a problem with the condensing side of the unit. Does the compressor (motor) cut in when you switch on? Is the condenser (aluminium finned radiator) blocked with dust / debris? Is the thermostat set correctly? Is it set to heating or cooling? Check the basics before calling in a technician.

1. How do computers output a signal without an input? [closed]

Program is just a sequence of pulses/switches. Switch on your fan, bulb and motor. Name the buttons F, B, M. And you have made a language. Bring a microcontroller or rasberry or what ever. Feed the squence in their memory, registers or flip flops. Play it whenever you want and you will turn on the fan,bulb,motor with the same sequence.Basically its your clicking on the keyboard that turn on the switches of transistors etc. Transistor is i guess the smallest unit of computers. These transistors make many things.

2. Why does my I-phone only charge when plugged in to my car charger?

To be uncomplicated you could purchase an in-motor vehicle charger for most cell phones for low fee on EBay. I basically does not probability it - how a lot are you going to ought to pay for a clean telephone ? understand that you are not any more basically risking the phone battery inspite of the indisputable fact that the phone battery charging circuits. Blow those and the phone is an ornament

3. Boat motors with the long drive shaft?

In this size boat and motor, there is little difference that you will note. Maybe a little more sensitive the angle adjustment (thrust bar) but no big rooster tail, or excessive fuel consumption. Lack of power due to drag should be minimal. With other boat and motor combinations you might have more problems, like on RIB's or if you are trying to "plane", but in your case it should be a problem

4. 1993 Ford Crown Victoria LX (non police) - Lifter clicking?

You do not want to keep that thick oil in you motor, it's hard on you oil pump pl it want pump the oil through the motor right, you may blow it up by using that thick oil. I do not know if auto zone sells SEA-FOAM engine treatment , but O are illy auto parts does, just add that to your oil for a while then replace the oil , it should help with that clicking noise. I've seen cars run for years with lifter noise.

5. What is a bent tranny bracket for 2007 nissan quest?

It's usually a piece of stamped or cast metal that supports the shifting linkage or cable.sometimes it's the actual piece that moves the gears.but do not worry it's on the outside of the tranny.cost would come down to price of bracket and labor to unbolt old one and bolt on new one.I do not know where yours is located but it may have to be put on a lift. Unless your talking about a transmission mount or motor mount.Thats a rubber bushing in a metal support bracket that aligns and isolates the trans or motor to the chassis

6. If I swap cameras, will my lens keep appropriate focus?

There's no optical difference that would would make what you are suggesting be insurmountable.The variation in actual registration distance between two Canon EOS bodies will likely be less than the slight variations we experience with film from one frame to the next as it is rolled through a film body after having been stored curled up in a canister for several weeks/months/years.Only when we started using perfectly flat, non-moving, high resolution digital sensors and "pixel peeping" the results did the miniscule differences between one camera and the next, as well as between one lens and the next, start to matter very much. The distance covered by one "step" of the lens' STM focusing mechanism is also likely to be a distance comparable to the manufacturing tolerance of the EF mount's registration distance. There is a non-optical issue, though, that at first glance looks like it could prevent what you suggest from working.Your STM lens is focus-by-wire. That means that there is no direct mechanical connection between the lens' focusing ring and the lens' AF motor. Instead, the manual focusing ring is an electrical switch that sends its position changes to the camera and the camera sends a signal back to the lens to move a certain amount.Believe it or not, even a film camera as old as the EOS 3000N is perfectly compatible with Canon's new focus-by-wire STM lenses. So are all other EOS film cameras. When the STM lens is attached to the EOS 3000N with metering active, moving the lens' focus ring will cause the camera to send signals to the lens' AF motor to reposition the lens. But here's where the issue comes in: Most STM lenses have the following (slightly paraphrased) statement included in the lens' handling instructions: When the camera is turned on or when the camera is 'awakened' by pressing the shutter button halfway down when the camera is off due to the use of the auto power off function, the lens performs an initial reset of the focus lens.This could be a fly in the ointment for obvious reasons.It turns out, though, that the above advisement only seems to apply to STM zoom lenses and a few EF-S STM prime lenses, such as the EF-S 35mm f/2. 8 Macro. The Instructions for the EF 50mm f/1. 8 STM include no such warning. Nor do the instructions for any of the other STM lenses I looked at that are prime, rather than zoom, lenses.You should be fine. As always, though, there's nothing to keep you from testing this method ahead of time just to be sure. Even if the night sky where you are is not as dark as where you will be going, you can still use the brightest stars in the sky to focus your lens using your Rebel T6/1300D and then place the focused lens on your 3000N and take a few test shots. I would do it two or three times, with 2-3 test shots each time. Just write down your frame numbers for each test cycle so that you know what you are looking at when your film is developed and printed

Problems with Central Heat and Air.?
You use different speed taps for heat then you do cooling....have a tech come out and hand wire unit to your heat/furnace fan tap...as long as bearings are ok....if you are trying to get by w/0 changing motor this would be only way. but its the motor. use your high winding and use it for cooling/not the greatest and will increase air flow in cool mode resulting in not as good dehumidification.but have a tech come out...describe your problem...make sure hes familiar with that make n model.most have a insert type ice cube fan speed relay. ....have him Meg the fan motor etc . ...or at least check motor thoroughly. ..if you have a burnt winding then replace motor...relays only interfere with operation if they are burnt/and are causing a voltage drop.also most furnaces have 115 volt motors back then or shaded pole motors. but there were a few 230 volt motors used if so it will have a dedicated run capacitor.something that would be checked all in the service call1. Robot Platform | Knowledge | How Electric Motors WorkElectric motors are found in most electrical and electronic appliances: Fans, drillers, electric engines, DVD players, washing machines etc. creating rotary motion. They are also used in saw mills and cutters where these motors are mechanically designed to create linear motion. Electric motors are based on the principle of electromagnetism. The mechanical construction uses two main components; a Stator and a Rotor. Stator (as in stationary) is a stationary component of the motor and rotor is a rotating component. Stator generally has permanent magnets (in some cases electromagnetic windings), and rotor has electromagnets (in some cases permanent magnets) attached. Ideally one of the two is a permanent magnet and the other is an electromagnet. When electric current passes through the electromagnet, it creates a magnetic field generating a magnetic force between the stator and the rotor. The attractive and repulsive forces between the electromagnet and the permanent magnet make the rotor to turn and rotate. To get the rotor to turn, the electromagnets create a repulsive force at one end (pole) which attracts the permanent magnet towards the other end of the electromagnet.Once the rotor does a half-turn, the poles of the electromagnet flips (North to south or south to North) pushing the rotor further towards the other end. The process continues creating a circular motion. Number of times the rotor rotates in one minute determines the velocity of the motor, measured as Revolutions per Minute (RPM). Hence whenever you intend to buy a motor, always watch out for RPM and torque of the motor. Installing gears can increase either torque or velocity, but reducing the other. AC Motor: Motors are designed to run on Alternate current (AC) or Direct Current (DC). However, it is very uncommon to use AC motors in our mobile robots as they are harder to use, and most of our robots and circuits are DC powered. Therefore use of AC powered motor is limited to stationary and industrial robots. DC motor: DC motors are very easy to implement and most commonly used actuators in robots. There are different types of DC motors available and in the next section, we will discuss the various DC motors available.2. How does the Koenigsegg Regera work?Well, you have posted the link to the website, where they explain it, and also give this image:There are three E-motors. Two on the axes, and one on the same shaft as the combustion motor (C-motor), which connects to the axes via a hydraulic coupling and a differential with a ratio of 2.73Now, let's play with that numbers. The C-motor has its red line at 8250RPM, so it turns the axes at 8250RPM/2. 73=3022RPM. The rear wheel dimensions are 345/30 R20 Y, which means they have a circumference of 2.17m. So, at max RPM, the car does 2.17m * 3022RPM = 6558m/min or 393km/h.They do not state a top speed, but they write something like 20s from 0 to 400km/h. So it is feasible that the C-motor is connected to the axes via a 2. 73 ratio differential. However, the car would drive at 47km/h when the motor is at 1000RPM...The solution is also written in the text of the website:Koenigsegg has developed a clutch-slip mechanism that uses the hydraulic coupling to convert torque at medium/high speeds during fast acceleration. This allows the combustion engine to gain revs and power, thereby giving the sensation of a traditional downshift with the associated aural enjoyment, even without the traditional gearbox. So, the answer to your original question is: They do have a torque converter like most other automatic cars, just a bit bigger / more sophisticated, so it can replace a gearbox.(And I wonder why the put that third E-motor onto the shaft of the C-motor - a torque converter always steals some power, i.e. fuel/battery. But I guess that does not matter here, people are interested in peak performance, not efficiency / endurance).3. I need a diagram for a ford f150..?I do not have a picture that I can send to you but it sounds like you have a 5.4 engine and the plugs are located in the center of motor on the intake and you will have to pull the fuel injectors off, the fuel rail and replace the o-rings when you go back together....this is a very big job
Businesses Are Turning to Shredding Companies to Help Them Destroy Incriminating Documents
Paper shredding can be time consuming. If you've been ordered by a sweating line manager to destroy a load of paperwork in a hurry, things can get a bit stressful - particularly if you're stuffing it into a Fellowes PowerShred P-20 (£17.49, plus VAT) which only handles five sheets at once and pushes them out at the rate of 2.5 metres per minute.This week, staff at Kids Company claimed that they were told to shred client files just before the beleaguered charity's collapse; it's unlikely that they'll have been using a feature-packed Rexel RLWSFM9 (£6,600, plus VAT, nine sheets at once, 4 metres per minute) but even if they had, it would still have felt too slow. Anyone with shredding experience will confirm that: a) it's laborious; and b) they wished someone else would do it. "You've generally got to have a member of staff standing over the machine," says Daniel Hawtin, managing director of The Shredding Alliance. "But we can shred in 15 minutes what would take someone five hours on an office shredder." That's a proud boast, and it's one that shred-weary businesses are becoming increasingly seduced by. "There are six companies in The Shredding Alliance," says Hawtin, "and we have a network of independent companies that work with us - but it's impossible to put a number on what the industry is worth. The problem is that it's not regulated in the UK. You could literally go off this afternoon and start your own shredding business." To provide peace of mind to customers, reputable organisations such as PHS, Shred-it and The Shredding Alliance boast of stringent security measures and their close adherence to the BS EN 15713 standard. "It's the dummies' guide to confidential shredding," says Hawtin, "covering everything from how the person collecting the paper is vetted to how it's transported, shredded and what happens to it after that." Of course, our need to annihilate all trace of confidential (or incriminating) pieces of paper goes back millennia, but it took a German toolmaker to turn it into a thriving business.Adolf Ehinger was quietly printing and distributing anti-Nazi material in the mid-1930s. But when a neighbour spotted some in his dustbin and threatened to report him, he took inspiration from the pasta machine in his kitchen and built a hand-cranked paper shredder, later adding an electric motor. When he first took it to trade shows, people laughed. But during wartime it caught on, and by the 1950s the company EBA Maschinenfabrik had become huge - particularly in America."Yes, this industry is massive in the USA," says Hawtin. "The regulations are a lot more stringent - six or seven decent-sized businesses out of 10 will use a shredding service. Over here it's more like two or three." Mounting corporate anxiety might well drive that number upwards; Shred-it's list of document security pitfalls is enough to provoke hyperventilation - failure to secure waste bins, unsecured printers, taking work home, leaving stuff on whiteboards..."You've got to be careful," says Hawtin. "In this office, no paper leaves without being shredded. Junk mail, everything. If you're not shredding and you're hoping for the best, you've got a whole host of problems on your hands." Weirdly, as business security concerns increase, the younger generation appears to be less likely to give a hoot; in one survey 34 per cent of "millennials" described data theft as a victimless crime. But as we move to being paper-free, shredding services are moving with the times. "We do media destruction too," says Hawtin.However, before you go into a shredding frenzy, be careful; any attempt to reassemble the "micro-cut confetti" produced by modern shredders will be very long, very tearful - and ultimately futile.
Yes, That Elephant Can Dance: General Motors Chief Talent Officer on Innovation at Scale
The challenge of injecting innovation into large, staid, and stalled organizations has long vexed leaders, consultants, and academics. The list of failed efforts goes on and on, including Yahoo!, Motorola, Blackberry, Sears, HP, Kodak, RadioShack, and that terrible merger between Chrysler and Mercedes-Benz. Yet there are exceptions. Some tired old companies do turn vibrant. And there are well-told stories about how and why old struggling companies have beat the odds and changed their cultures, practices, and products for the better - although it is important to remember that nothing life is permanent, so such successes are best viewed as temporary and precarious.My favorite such stories include Lou Gerstner's Who Says Elephants Can't Dance, which I riff on for the title of this piece. Gerstner details how he led IBM's turnaround when innovation was stalled and the collective energy of the company was focused on politics, in-fighting, and preservation of outdated traditions rather than excellence. And IBM customers were routinely confused and neglected by the company. Creativity INC describes how, after Steve Jobs sold Pixar to Disney, President Ed Catmull and others from Pixar revitalized the spirit, confidence, and storytelling at the iconic but then struggling Disney Animation Studios. And one of the best such tales is James Surowiecki's 1998 New Yorker piece "The Billion Dollar Blade." It tells how a group of insiders at Gillette banded together to oust leaders who were leading the company into "commodity hell" and returned to Gillette's roots as a product innovator.I have a new candidate for anyone intrigued with the nitty-gritty of instilling innovation at scale: Michael Arena's new book Adaptive Space. I read an advance copy several months ago and was taken with the instructive blend of theory and research (especially on social network theory and innovation), stories about GM and other companies, and practical advice about what actually works. The book is compelling and fun to read, and accomplishes this without a hint of breathless hype or exaggeration.Many Silicon Valley companies that were once cute smart little startups but are turning into big dumb companies could a learn a lot from from Adaptive Space (including Tesla). As Michael shows, making innovation happen in a big company is a lot different than in little one. Michael's book will be released tommorow and we dropped our Stanford ecorner FRICTION podcast with Michael yesterday - which we titled "Agile on Edges: Managing Misfits." (You can listen to it, or if you prefer, read the transcript).I can't quite believe that I am praising book written by a GM executive. A decade ago, I was convinced that GM was doomed because it had a broken culture (based on frequent direct and indirect interactions with the firm's managers and executives). In 2008, I wrote a very critical post about the company that argued GM's core competence was captured by the phrase "No We Can't" - GM managers were the most skilled people I had ever met at explaining why, although they knew better ways to do things, it wasn't a good idea for GM to do them. They were a perfect illustration of The Knowing-Doing Gap, which Jeff Pfeffer and I wrote about back in 2000. And you likely recall that the company did, in fact, did go through Chapter 11 Bankruptcy in 2009 and was bailed out by the U.S. Government.What a difference a decade makes. GM paid back the money. Under CEO Mary Barra'sleadership, GM is financially healthy (some analysts make the case that the stock market undervalues GM, especially compared to Tesla). And, based on my admittedly biased view, the "no we can't" mindset is fading fast and innovation is evident in more and more GM people, practices, and products.The beauty of Michael's book - and our conversation on the FRICTION podcast - is that he digs into powerful nuances the propel innovation in big companies. He has much insight into how to dampen and overcome bad friction in big companies like General Motors, and about when friction is useful too - including resistance to new ideas, conflict over how promising new ideas should be realized, and careful (and sometimes slow) development of promising ideas before they are implemented at scale. He explains that, yes, some parts of big companies can and should be entrepreneurial, experimental, move fast, and do risky things; but it would be a disaster if everyone acted that way. Following work on the ambidextrous organization, he suggests that big companies must also simultaneously accomplish the routine, proven, and well-rehearsed stuff that makes money right now.I was taken with Michael's analogy that, to strike the right balance between scale and speed, he thinks of the core of a big company as much like a supertanker - where routine things happen, people have well-defined roles, and changes in direction are made with much forethought and unfold slowly. On the edges, however, are many speed boats, which move fast, travel to many new places, and try new things - all without affecting life on the supertanker. Many speed boats fail. Those that succeed get bigger and bigger, and when they become really successful, often come aboard and become part of the supertanker's operations.Michael's insights about how to manage the links between the supertanker and the speedboats are especially useful. Drawing heavily on social network theory, Michael suggests that, while having very smart people is important to innovation, more and more research suggests having the right blend of people and positions in the network, and creating the right connections between them, is the key to being a big innovative organization - for binding together what happens in the supertanker and in the speed boats. For example, he talks a lot about challengers, people who "break through the current status quo," and "see a different set of possibilities" The key, however, is that constructive challenges aren't just complainers and critics - they don't just annoy and distract their colleagues, and thus create dysfunctional friction. Instead, "they help break down the brick wall or pull other people and their ideas through the brick wall so that it can become the new big idea." And, as Michael added, they either have solutions to problems they complain about or ideas about how to develop solutions.Our interview and Adaptive Space unpacks the different kinds of roles and people that work together to bring new ideas into the core of social networks. Michael pointed out that "ideas developed inside small teams are 43% more likely to be rejected by the larger organization." But when new ideas are advanced by "energizers" - people who leave others feeling more motivated and enthusiastic about their work, themselves, and the organization - the newideas are far more likely be heard and spread. The implication, which has been around the innovation literature for a long time, is that the most successful innovators are adept at getting others excited about new ideas, about their roles in helping to develop and spread the ideas, and about selling the ideas to outsiders. Or if they are skilled at finding or inventing new ideas, but aren't adept energizers, they make innovation happen by teaming up with expert energizers. Steve Jobs and Thomas Edison were master energizers, but neither of those famous innovators had the best technical skills in their companies or industries. They become renowned innovators by teaming-up with more skilled inventors and technologists.I also like Michael's observation many of the best innovations already exist inside the organizations that need those ideas. He explains that social networks play a crucial role in finding and spreading these good but largely unknown and unused internal ideas. The role of "brokers" is key - these are people with connections to diverse people, groups, and ideas inside and outside of the organization. Because they have their fingers in so many different pies, brokers are often the first to learn about good ideas in their organizations and are in position to spread them to places where the ideas are not known or used. Michael says that brokers often uncover "positive deviance," pockets where great things are happening and that most of their colleagues don't know about. For example, Michael talks about a nurse at Einstein Medical Center in Philadelphia who knew about an area that had far lower rates of MRSA infections than elsewhere the hospital. The nurse attributed these lower rates to a janitor named Jasper Plummer. He taught doctors and nurses to remove their splattered surgical gowns in a way that sealed the soiled gowns in their surgical gloves. That method made his clean-up job easier and isolated the infection in the gloves. That nurse is a textbook example of a broker: Her connections to that unit meant she was one of the only a few people who knew about that practice and was also connected to the many other people and parts of the hospital who could benefit from using it - and thus Plummer's practice was spread it throughout the medical center.A final thought about Michael Arena's attitude and perspective. When we talked, Michael acknowledged my grumpy assertions that life in organizations is often messed up, frustrating, and exhausting. Yet he did not want to dwell on the causes and symptoms of dysfunctional friction that are rampant in nearly all big organizations. He wanted to talk about how to overcome and remove these and other obstacles to innovation - and he especially wanted to talk about the good things in organizations, and how networks enable people use their connections to find, develop, and scale good ideas. Michael's Adaptive Space, Lou Gerstner's Who Says Elephant's Can't Dance, and Ed Catmull's Creativity INC differ in many ways. The authors of all three of these wonderful books, however, have the same perspective on what it takes to fix a big stalled company: You can't let the bad news and setbacks get to you down. Your job is to make things a little bit better each day. And there is always something constructive you can do to make that happen.This piece was first posted on Linkedin.I am a Stanford Professor who studies and writes about leadership, organizational change, and navigating organizational life. My latest book is The Asshole Survival Guide: How To Deal With People Who Treat You Like Dirt. Before that, I published Scaling Up Excellence with Huggy Rao. My main focus these days is on working with Huggy Rao to develop strategies and tools that help leaders and teams change their organizations for the better - with a particular focus onorganizational friction. Check out my Stanford "FRICTION Podcast" at iTunes or Sticher·RELATED QUESTIONWhat is the working principle of an electric motor ?An electric motor uses the attraction and repulsion of magnetic fields to produce motion. The simplest is the permanent magnet motor. A simplified version is shown below.Placing a coil of wire inside a permanent magnetic field and fixed so it can freely rotate. Pass a current through the coil of wire and it will rotate to the perpendicular position. Now reverse the current flow and the coil will spin 180 degrees. The brushes and the commutator does the switching directions of the current through the coil at the appropriate moment to keep the coil rotating in one direction. This is the basics of all electric motors.Fleming's left hand rule above describes the relationship between the main magnetic field. The current flowing in the coil and the direction of the movement or forceNow we can use electronics to do the switching instead of the commutator and brushes. These motors are called Brushless DC motors.Larger motors require a stronger magnetic field and more electrical ,power to drive it faster and with more torque. Stronger magnetic fields are created by electromagnets.AC motors use induction from the stationary windings to create the second magnetic field in the rotor. That induces currents in the rotor and these currents have their own magnetic field which interact ( repel and attract) with the main magnetic field to make the rotor rotate
What Is a Disable Input for on a Motor Controller For?
This is a H-bridge motor controller which works like this:simulate this circuit - Schematic created using CircuitLabHere, SW2&3 are closed, so the left terminal of the motor is connected to the negative, the right to the positive terminal of the supply. You can reverse the direction by closing SW1&4. (but never have 1&3 or 2&4 closed at the same time)Normally, D1 is LOW and D2 is HIGH. As soon as one of the both signals is in an other state, all switches will be opened ("high impedance") and there will be no connection to any terminal of the source (Note: to switch off the motor, it's usually sufficient to open just the lower switches, or just the upper.)If you apply a PWM signal of 70% duty cycle to D1, D1 will be HIGH 70% of the time - the switches are all open 70% of the time and closed 30%. As stated in the comment, this can be used for two end switches. However, the combination of one active low and one active high signal can be used for higher safety: Imagine a door which should not be opened while the motor is running. A simple door switch may fail and the controller will not notice that someone opened the door. Now you can use a change-over switch which opens one circuit and closes the other. This will not work if the switch gets stuck in one position, but it still adds some reliability to the safety system1. Robot motor help!!! Electric Motor and Battery Questions.?Now one can answer this because we do not know what the motor current will be and we do not know the battery ratings2. Where's is the vtec located in the motor?The VTEC system (Variable Timing and Lift Electronic Control) is a system that uses 2 different camshaft profiles, one for low RPM torque and economy and the other to maximize volumetric efficiency and power at high RPM. The system consist of an extra set of followers that are hydraulically engaged by a locking pin and allows the valves to open more (more lift) and for a longer period of time (Duration) when the electric VTEC solenoid allows engine oil pressure to the actuator there is also a VTEC oil pressure sensor that sends feedback to the PCM (Powertrain Control Module) ADDED: Wayne gets T.U for his description, the other poster "You drive a mopar" you REALLY lose, but you do not even know it yet!3. What is an orbital motor?ANSWER No Orbital motor and hydraulic motor are not synonymous terms.A hydraulic motor is essentially a hydraulic pump in reverse. It has one or more pistons that move in a cylinder, with valves and timing, rather like an internal combustion engine powered by compressed air. By comparison, here's an orbital motor. Main advantages are that the "motor" itself is quite small, and generates little heat compared to an electric motor. Also, this is a high torque but low speed shaft, so there's no need for a gearbox in situations where an electric motor would need a gearbox.Downsides, its low speed, so if you want to move something quickly, it may not be the best motor for the job. You will also need pressurised lines to and from the motor to your pump.Here's a cutaway showing more of how it works. Notice the shaft in the middle is not flat - this is the rotor shaft and is seen in the middle of the blue picture above, and is not flat.4. difference between scooter and motor cycle?I think the most obvious difference is the engine position and consequently frame design. There are so many variants that this is just a generality but the engines of scooters are placed as close to the rear wheel as possible, frequently at the side of the wheel, a motorcycle engine is positioned to the centre of the frame5. What size motor for a boat ?10 hp 20 hp 50 hp 75 hp 100 ho,,,,150 hp,,,thats the worst question,,,a lightweight open 14 footer will be ok with 15/hp..my buddys 18 foot fiberglasscuddy cabin has a 150 merc6. how to winterize a boat motor?When boating season ends, some people park the boat in the storage yard or driveway without a thought for starting the engine the next season. In so doing, they insure that the first start up of the next season will be troublesome or expensive or both. Many of the problems associated with that first trip to the water can be avoided by taking the time to winterize the motor before laying the boat up for the winter. Step 1 Change the engine coolant and thoroughly rinse the cooling system, including the engine block, heat exchangers, water heater and the overflow bottle. Refill the cooling system with a 50/50 mixture of fresh anti-freeze and water by filling the heater hose with a small hand pump and filling the engine when the mixture returns from the water heater to the engine. When the coolant fills the "fill tank," reconnect the heater hose to the engine. This will eliminate almost all of the air from the cooling system. Step 2 Change the engine and transmission oil, draining the engine oil from the oil pan sump and the transmission oil from the gear box sump through the oil drain plugs on each. Replace the old oil with the new oil of the proper grade, through the oil filler cap. Change the in-line oil filters and, if so equipped, the Racor cartridges. Step 3 Remove the flame arrestor from the engine air intake. Spray fogging oil into the carburetor while the engine is running to prevent corrosion in the carburetor and jets. Step 4 Shut off the fuel supply valve or disconnect the fuel line from the motor and let the motor run until it runs out of fuel. When the motor begins to die, put one more heavy spray of fogging oil into the air intake, through the flame arrestor. Step 5 Drain all water from the muffler canister. Step 6 Seal all air inlets, crankcase and transmission vents, exhaust outlets and tank vents with plastic wrap and duct tape. There are other tips in the website below.
PWM Controlled MOSFET Based DC Motor Driver, Stuck with Reverseing Direction
The reason you see the sparks is because you are open-circuiting a charged inductor (ie the stator of the motor) Thou shall not open-circuit a charged inductor, thou shall not short-circuit a charged capacitor. The stator of the motor has been "charged"... you have at one point applied a voltage to it to permit current to flow. For whatever reason (intent or oversight...) the relay has opened the stator terminals. The inductor MUST keep the current flowing & due to: $V = LfracdIdt$, a sudden (attempted) change in current can only result in an increase in voltage which leads to sparks, avalanche or insulation breakdown. To remove such sparks you could consider using a H-Bridge arrangement but these are more involved. As a "poor mans" replacement, some sort of snubber across the motor would be the next best thing. An R-C-Z would be one option1. reversing DC motor rotation using TWO limit Switches Problem !! need helpNormally you use state machine for this kind of programming: you have a state variable that remembers what you are doing, and depending on the current state you decide what to do next. Below is an example with two states. I have embedded a few assumptions about the wiring of your motor and your switches, which may be wrong, so you have to check the code.This will start in the MOVING_CW state, but you have to actually start the movement in setup(). It has the drawback of having long delay()s in the loop, which is undesirable if you have other tasks to perform. These delays can be removed by "remembering" that you are waiting as two extra states:2. how do i hook a small 12vault dc motor to a battery when it doesnt have any wires ?There is only one motor shown in that link, and that has two solder tabs. (I can see only one, but I am sure there is another one on the other side). So you solder the wires to those two tabs.3. Change Direction of 12v DC Motor Rotation using RelayMaybe something like that could work.Switches are on the two ends and trigger the change of direction of the motor.The relay should be of the 'latching' a.k.a. 'bistable' type.simulate this circuit - Schematic created using CircuitLab4. What if we don't use split ring commutator in a DC motor?Cosider the simplest of motors, one with a single coil of wire within a fixed magnetic field. The split ring commutator is a primitive switch so the that DC electricity goes through the coil one way, and then reverses the current when the armature turns 180 degrees. Without a split ring commutator the current would not reverse when armature reverses, and the magnetic fields of the rotor and stator would clash and the rotor will stick in a position and not turn.5. Wiring DC Motor Controller board to Raspberry Pi 3QuestionPie fired - Why?AnswerThere is 50% chance that the pins 1, 2, 3 labelled below are hardwired to Gnd or Vcc. These pins are used for dry run, without Rpi connected. You use a jumper to short the pair of pins to check out if the motor can move. But if you connect your Rpi GPIO pins to these dry run test pins, Pi fried instantly.You might use a multimeter to measure the voltages at these pins, or give me the link to the motor driver to check out the schematics to confirm6. What kind of DC motor is this and what does the circuit do?That looks like a DC motor of the type used in tape cassette players.For music reproduction with accurate pitch constant motor speed is required. Achieving this in battery powered equipment requires addition of a voltage regulator or speed controller as DC motors' speed varies (nearly linearly) with voltage. The potentiometer in the motor allows the speed to be factory set.I modified one such motor on a good tape deck, adding an external pot and switch to allow some pitch adjustment so that I did not have to keep retuning my guitar between tracks / albums.The TDA1151 seems to be one simple device intended for such applications.7. Battery Specification for using a 1 HP DC Motor?One horsepower is equal to 746 Watts; in reality, however, a 1 hp AC induction motor draws 1500 Watts at 1 hp load. If you use a DC motor, you would connect batteries in series. If you are designing uninterruptable power for an AC motor, the requirements are formidable. First, you need an inverter capable of 1500 Watts comtinuous and 9000 Watts starting surge. Second, at 12 Volts the battery will have to supply 150 Amperes. A back-up supply of this size is not practical as opposed to a standby generator. A suitable inverter will be expensive (if available). The actual battery requirement would be several hundred Ampere Hours of capacity for every 20-30 minutes of operation.
Electric Bikes for Sale at Best Buy - Cbs News
Are Americans ready for electric bicycles? Some celebrated entrepreneurs, including Lee Iaccoca and Malcolm Bricklin, have lost their shirts in the category, but Best Buy is convinced that the electrification of transportation now extends to two-wheelers. It has started an experiment to sell several forms of assisted pedaling (as well as Segways and the Brammo electric motorcycle) at 20 stores in California and Oregon. One of its ebikes in a lineup that includes the Baja Motorsports moped and Currie Ezip is the $2,699 Ultra Motor A2B, which I recently borrowed for some memorable test drives.Best Buy is serious about this, and recently invested $10 million in Brammo. Neither Ultra Motor nor Best Buy will comment on how many A2Bs the retailer has sold three months into the program, but Best Buy's Kelly Groehler says, "One of the things that's important for the future growth of [our company] is staying ahead of where technology is in people's lives." The Geek Squad has been trained in ebike maintenance. Paul Vlahos, vice president of sales at Ultra Motor, isn't sure how big the ebike market is, citing competing estimates of from 20,000 to 200,000 sold annually. The line between ebikes and electric scooters is somewhat blurry, especially with the not very bike-like A2B. "Unlike more mature categories, there is not very good sales data on ebikes," said Vlahos. "Our distribution points continue to increase daily as more dealers and retailers see new trends, and as the category gains awareness and acceptance among U.S. consumers." Ultra Motor has 250 dealers in the U.S.--spread among traditional bike stores, green specialty retailers and motorsports locations."We have some strong independent dealers out there," said Vlahos. "We're unsure how the Best Buy relationship will ultimately work out, but we're excited about it. Will they expand into other stores? We hope so, but we're unable to speak to their plans for the category." Trending News Google Cloud Outage Missing Connecticut Mom Virginia Beach Shooting Protester Interrupts Harris The private Ultra launched the A2B in warm-weather states California, Arizona and Florida in September of last year. It's now available in bike-friendly locations such as Seattle, Portland (OR). San Francisco and New York. The lithium-ion batteries are guaranteed for a year, and the motor for two years. The high price might be a deterrent for some customers, but the beauty of the A2B and its competitors is that no motorcycle license is needed--in most states, this scooter-like device is regulated as if it were a bicycle.A very sleek design with the batteries enclosed in the frame and the electric motor in the rear hub, the A2B resembles a small scooter. It's somewhat heavy at 72 pounds, which makes unassisted pedaling uphill somewhat of a chore. But twist the throttle and it takes off with alacrity, offering 20 miles of cruising range. The With wide tires, the bike is extremely stable and easy to ride. Recharging is simple, and takes three and a half hours. A small box plugs into the wall and into a three-pin port on the bike.Vlahos says Ultra Motors sells "thousands" of A2Bs annually, but he declined to be more exact. "We're evaluating expansion into the scooter category," he said. That makes sense, because the A2B is most of the way there already. And we hear Best Buy is selling what we might call "escooters."
Steps in Rewinding Three Phase Motor?
Step 1 - remove stator from motor housing. - generally done with a 'gas circle' this is a ring with about 8 - 10 gas burners. It will expand the steel casing and let the stator drop out. Step 2 - remove burnt copper windings, usually done by sawing one end off, then pulling it out of the slots from hte other end. This will generally pull the insulating materials out with it. Step 3 - insert new insulators in the slots. Step 4 - divide the number of slots into 3, starting at the desired slot start feeding in the new copper coils in one end out the other and so forth, making sure that each time it is going into the correct division of 3 slots to keep the magnetic syncronisation correct. Step 5 - once all the coils are completed dip the motor into the curing solution to fully insulate the coils ( see my other answer for heat ratings ) Step 6 - re install into stator housing with the gas circle and rebuild.( Take care to use new bearings on the motor shaft as the old ones will be full of carbon. Interesting fact for you, if you apply voltage to the stator when it is removed and put a ball bearing in it you will be able to find the spot where the coil has failed, bearing will go round in the stator with the magnetism and drop when it comes to the open link. This is done when a motor continuously fails and the phase recognition needs to be carried out to ensure there is no fault with the power being supplied to the motor. Hope this helps.1. Electric Power comes back when I open up warm tap water and then goes when I close the tapAs already said by other authors, the interrupted phase is supplied by one or both of the other 2 phases when the water heater switches on (backfeed). It could be a also multiple problem with a combination of shortcut(s) and low resistances between phases or phase to Neutral. This could increase the voltage to a level thatdestroys the devices that are fed by this backfeed via the water heater, since the water heater's resistances are very low and the sum of 2 phases with 120 degree difference could be fed back. The heater is connected to a 3-phase breaker that can only interrupt 3 phases alltogether, even if there is an overload on 1 phase only. That breaker apparently did not trip - or the heater does not have a combined triple circuit breaker, but only 3 separate ones, which is against the standard/code.Most likely an upstream fuse or breaker did trip, which is separate for all 3 phases. Do neighbours report problems with some electric circuits not working? If not, the problem is within the own house/apartment.The heavy main fuses/breakers upstream of the water heater directly at the incomer box of the supplier should give the downstream breakers the priority, i.e. a short in the wiring of the water heater should cause the downstream breaker(s) to trip, and not the main fuse/breaker. Another 3 main fuses or breakers (for each phase) normally sits upstream close to the meter, and one of those could also have tripped.2. How much energy does it take to change water from the solid phase to liquid phase?A calorie is a unit of heat equal to the amount of heat required to raise the temperature of one kilogram of water by one degree at one atmosphere pressure 1 calorie = 4.18400 joules3. Finding phase velocity for froude number scalingI am not sure where did you brought the would eep water relationship' in here. If you are dealing with usual water wave (gravity, surface, linear, and close to sinusoidal wave form), then the relationship you would need to use will be dispersion relationship.$omega^2 = gktanh(kh)$As you are assuming deep water, it becomes: $omega^2 = gk$Which leads to almost exactly same equation you came up with, but one less power of T:$lambda = dfracgT^22pi = 72m$and phase velocity of 10.61 meter/second.(Actually, your original calculation, with $T^3$ was incorrect. That should have give you wave length of 491 meter, instead of 712 meter)Additional comments:
CBT: I've Never Riden a Bicycle in My Life Or a Motorcycle?
I would at least learn how to ride a bicycle to get a sense of balance first, then look into a small bike1. Isn't being a vegetarian ethically pointless if you think about it?I am not a vegan, but I abhor cruelty to animals. On the other hand, as hypocritical as this may sound, I am an omnivore because I was made that way. I have iron poor blood and need to eat meat. unfortunately also used to work in a factory, and, unfortunately, suffering is a necessary part of not just the human experience, but, it seems, of the entire planet. Everything we wear, buy, or use, came from some suffering. Most of the products we buy are by-products of cows, and even the streets we drive on and the lifestyle we lead is the result of suffering. As with the "Yin-Yang" principle, there should be balance in all things. From the suffering of the road crews, we have roads to drive on and lines painted on those roads to keep us (mostly) from killing each other. From the diesel-coated cardboard dust phlegm of UPS factory workers, consumers can have DVDs, Christmas presents, etc. to make them happy. And so on. We are the only species on this planet (so far as we know) that experience such a level of self-consciousness. Carnivores eat meat, and it is not cruel, it's their nature. I used to have a seal-point Siamese cat who was an excellent hunter, and he used to crunch on the bones of mice and kill all kinds of critters. We had dogs who would do anything to protect us. We as human beings are arrogant enough to think that our way is the only way, ignoring as we do the way in which *all* other species on this planet seem to accept their role and their place in the natural order of things. It is when we attempt to throw this balance off by "fighting" with each other that we mess up the planet. Yes, I know it's out in left field, but I am a third-option kind of guy. Hence, the moniker.2. is this a balance diet?warm canines are a hundred% junk nutrition because of the fact this is all processed fillers and man made products inclusive of a extreme quantity of animal fat. They incorporate no dietary fee and too much sodium. something is extra suitable than McDonalds (YUCK!) yet once you have been going to elect between the hotdogs and the cupcake, you would be extra suitable off with the cupcake. in case you heavily desire to lose the load then you definately will ought to make the sacrifices. decrease out ALL processed meals. as quickly as you get on your suitable weight, then you definately can handle your self to the occasional hotdog yet for stunning now, attempt to steer clean :o) attempt a turkey wrap with clean turkey, swiss cheese, avocado and tomatoes in an entire wheat tortilla rather.. yummier and in good shape :o)3. What is Blood Balance Formula?Entering the phase of life where you start progressing towards getting old is not an easy one since the body tends to become weaker with time. As people grow old their energy levels also begin draining; they start developing pain in their joints as well as the muscles. The power of memorizing as well as focusing too starts declining. Dieting, as well as exercising, can help people in their old age to some extent, but problems of blood sugar and blood pressure, cannot be completely relieved. Hence, it is advisable adding the efficient complement or supplement which will act as a shield against the process of aging. Read the entire inference to know more about the product called blood balance formula. It is a solution for both men and women, irrespective of their ages as well as health conditions. Blood Balance Formula is a broad and an all-purpose complement which assists in improving various aspects of an individual's body.

Where is the best place to find cheap motorcycle parts?UK, buy MCN local paper shop every wednesday3. Anyone know where I can motorcycle parts for cheap?Basic sites Amazon eBay Craigslist4. Motorcycle Parts 101: How to buy themI have learned hard lessons about motorcycle parts. Aftermarket and OEM parts alike range in price and quality. Sometimes, items that should "bolt right up" need more tweaking and finessing than if I just built something from scratch. Other times, making some non-standard pile of pieces jive goes so easily it seems like kismet. I am often asked questions about how things can be made to work together. I do my best to explain that sometimes the answer involves fabrication, which is usually greeted with a frown. I often steal Merch Specialist Mike C.'s phrase: "Custom bike problems, custom bike solutions!" In the spirit of making the parts ordering process less painful, I present some general thoughts I have developed on mo'cycle parts over the years. Some parts are replacements, some are upgrades Some parts are intended to fulfill a factory function, like an exhaust gasket. These look and act generally like the OEM parts they are intended to replace, so it's fair to expect them to behave like OEM parts. However, especially in the motorcycle aftermarket, a large portion of the available parts are intended to change the performance characteristics of your bike. Some parts are meant for the track only. Using a slick tire on the street will give you reduced performance along with a higher likelihood of crashing. Shinko photo. An item like a race slick is going to drastically change performance. It's going to grip like mad on clean dry pavement - at the expense of having awful wet-weather grip and terrible longevity, not to mention a warm-up time that will render it more or less unusable on the street. If you are a street rider, this is a wholly inappropriate tire, but if you shred it at the track every weekend, you will probably appreciate the performance shift. Before you order a part, determine whether you want the same performance as the part you are removing, or if you want to change it. Our Catalog Specialists spend untold hours verifying, studying, and even fitting parts in an effort to get maximum information to our customers about installation, fit, and purpose for a huge variety of parts. There's a little "fitment notes" tab that often has some real nuggets of knowledge that can help an installer. Our Geeks can help you with some of the more technical products if you are uncertain if those notes pertain to you. Strike while the iron is hot Aftermarket parts are generally unavailable for a brand new model. The manufacturers have to obtain the bike, tool up, and then start cranking out parts. After a bike is a year to a few years old, usually the amount of parts for that bike is at its zenith. Unless the bike remains unchanged for a long time (Kawi KE100s, Harley Shovels, Honda Gold Wings), parts availability through either OEMs or aftermarket manufacturers dwindles as stock gets sold down. If you do not believe me, compare the amount of exact-fit aftermarket parts that we sell for something like a 2015 Harley Ultra (1,170 on the day this article was authored) as opposed to a 2001 Suzuki TL1000 (40). Other items come into play here, too. The number of bikes produced is no small consideration when the aftermarket is gearing up to make parts. If you've never seen a first-year Aprilia Futura in person (I have not !), our meager offering of nine direct fit-parts kind of makes sense. Universal parts come in two flavors Universal is a term that gets applied often. I find it has two meanings, though. There are some parts that are described as "universal" that fit damn near everything. A throttle boss is a good example. If you have a motorcycle, odds are excellent this throttle boss will install correctly in about a minute and a half. With some "universal" parts, you have to take a lot of responsibility for making them work with your motorcycle. TC Bros. photo. At the opposite end of this spectrum are parts that are universal, but do not fit nuffin'. Take a peek at these universal rearsets. Out of the box, these do not fit a thing. It's up to the user to figure out how to mount them, to fabricate shift linkages, and determine that they are ergonomically viable. As you can see, it's a totally different type of "universal" fit. Sometimes, I order parts that "do not fit" and game the system. Mazda oil filters fit the old Triumph 865 Modern Classic motor handily. Similarly, Toyota oil filters spin right on to Big Twin Harley Evolution and Twin Cam engines. They work great for the Evo, but they will starve a TC for oil and smoke an engine. As you can see, trying to outsmart the people who do this for a living can either pay off or backfire. Do any of you remember when I was trying to mate up old and new Harley primary pieces to fix up that 1993 Softtail I picked up to flip? I had to do a little bit of finagling to get all that stuff to work together. To present a third scenario, sometimes fitments wo not include models or years that a manufacturer suspects will fit, but have not been confirmed. Monkey with your bike at your own risk. I picked up a set of exhaust pipes not too long ago for a Shovel. The flanges were welded on crooked. I suspected I could modify the stub pipe to work in spite of the crooked flange. (They were already chromed, so I did not want to cut it off and re-weld it.) Turns out I was wrong. I cut up a set of pipes that was made incorrectly, and that was on me. I knew full well what I was doing, and I did it anyway. A good rule of thumb is that if you are going to mount, modify, or even unpackage a part such that it cannot be resold, a retailer probably is not going to accept it for a return. When you start adding aftermarket parts, like crash bars and skid plates, make sure they do not interfere with each other. RevZilla photo. Some aftermarket parts do not work with others Because of the wide variety of aftermarket parts that exist, it's nearly impossible to test Replacement Part A with all of the myriads of combinations of parts a rider may elect to install. Parts manufacturers usually design their parts for use with OEM machines. Let me give you concrete examples: An aftermarket high-mount exhaust on a sportbike is generally incompatible with aftermarket saddlebags, but it will work fine on the bike as delivered from the manufacturer. Another good real-life example we see is in the ADV world. Often, a rider interested in protecting his bike will find there is a fitment conflict between skid plates and crash bars. Our very own Buzzsaw experienced this on his 2010 Triumph Tiger 1050. He found that Givi crash bars were a no-go with an SW-Motech skid plate. He's in a bit of a pickle because he likes the design of each of those parts, but he feels that the items that "jive" together are not constructed the way he would like. Food for thought, eh? Some aftermarket parts only work with other aftermarket parts There are lots of items that require separate purchases to work. (Remember "batteries sold separately" when you were a kid? Same deal!) A good example of this is a Harley four-speed mainshaft bearing support. This is used to help support the mainshaft when running an open primary belt drive. Guess what, though? Harley never sent a bike out in that configuration. If you want to run that bearing support, you need to junk your inner primary, which pretty much locks you into an un-oiled open chain or, more commonly, a belt. And if you have mid-controls on your bike, guess what? You are going to need to re-work those totally. Sometimes improvement projects can feel like they are spiraling out of control if other modifications were not anticipated. (Ask me how a taillight installation turned into an engine swap. I am kidding. Mostly.) You probably own electrical stuff, even if you do not want it If you bought an electronic or electrical item and had a change of heart, you are up a creek. Generally, you can not return these parts for several reasons. There's not a real easy way to test items like this if they get returned. Additionally, poor mechanics will sometimes use good parts to see if a problem disappears, rather than accurately diagnosing the root of the symptom. Sucks, do not it? Custom bike problems, custom bike solutions. Think long and hard before you embark upon electrical adventures if you are not a crack 'lectrical mechanic. I wrote this article for two reasons. The first is that I've been on your side of the parts counter. I know how frustrating it can be as a customer who did not receive a vital piece of information, usually made worse by someone who does not really care about my issue. The second reason is a bit more sublime. Call up a Geek, drop them an email, leave us a comment on a product video, or ping me right here on Disqus. Even if we do not sell the part you are interested in, we can help you determine if your bike setup and wrenching abilities are a good fit for a given product. Well, that's the end of the article. I suppose we must... part.
