P.M. D.C. Motor for Treadmill

Hi I am working on an Image 15.0 R Treadmill. As soon as you start it , it shuts down as if the circuit has been interrupted. I unhooked the drive belt so that there was no resistance to it and it does the same still. The speed sensor seems to be working okay so I pulled the controller (board) and tried re-flowing it. as I flip the treadmills switch on not starting the treadmill-just turning the power on the motor runs for about 3 seconds. Because the cover is off while I am working on it I can see that during that 3 second window the motor has a spark (bolt) from one of the bolts to the post (I think stater) the one that if the motor were disassembled the part spinning inside the copper wind. I don't remember what it's called (armature?) Anyway this arching does not re-occur unless I completely unhook the board once more and re-assemble. After re-flow the motor still just begins to load (start) bumps about 1/2 a rotation and stops. I read an article here that Iceng had commented about bringing his P.M. D.C. Motor model # c335483304 back to life......it is the exact motor....my girlfriend has been on me about fixing her treadmill so here I am. Anything would be of great interest and help to me. Thanks a million in advance. Troy

Drone not turning on? Answered

I have an Ardupilot 2.6 from 3DRobotics on their quad frame. I am using their power distribution board now instead of using one that I made myself. Before I changed the power board, my drone was working perfectly. Now when I try to arm it (enable the motors) it does not work. The light on the APM 2.6 blinks red when disarmed and is solid red when armed. It only blinks when I try to arm it. I am using a Turnigy 9x transmitter with a turnigy RX. I have tried replacing the RX and it does the same thing. I have a separate battery pack for the receiver because it seemed like it was not getting enough power with the 3DRobotics power board. Could it be a problem with the transmitter?

Need help constructing a transformer!!!

Here are my specs and anticipations for my homemade transformer: Im looking for my transformer to produce a voltage of 400vAC out of a standard 115vAC wall socket. If ive done my math, and this is where I would like do correctig if noticed I need a turns ratio of 1.2 : 3.5. That is 1.2 to 3.5 or 115 turns of primary and 350 tunrs of secondary. 115 X 3.5 = 402.5vAC respectivley. I have access to a fero-core so thats not a problem. Im using 22-20 gauge wire for the primary and 18-16 gauge wire for the secondary. If you find my wires to be of incorrect gauge please let me know. I realise 18-16 is rather large for a coil but I was trying to keep safety in mind do to the high voltage.

Vibromotors and GPS turn by turn navigation

Hello, for one of my university courses I have to develop a prototype that give turn by turn signals to a person by means of vibromotors. First I would like to say that my background is mechanical and I have no idea whatsoever of electronics or software. My full Idea (Don't know if feasable) is to use the turn by turn information of a smatphone navigator that uses GPS (like the one of google maps) to activate one of two vibromotors, there would be one vibromotor on the right arm and the other on the left, if a next turn is needed to be made (info from the navigator) a signal will be send to the the motor on the left arm, It will vibrate and let the user know that this next turn needs to be done. I need urgent help since I don't know which components I may need and how to develop the software or anything I will appreciate any hint.

Wireless Turn Signals

I have toyed around with the idea of making a jacket that has the turn signals and/or brake lights on the back. However, there is a twist, I would like to see a controller box to wirelessly send the signal from a scooter to the jacket. When the turn signals and brakes are used on the scooter it sends a wireless signal to the controller in the jacket which relays that to lights on the back of the jacket. I've seen some jackets with lights wired on to them controlled with an arduino.

Bluetooth speaker not turning on?

Hi, i made a basic DIY Bluetooth speaker with a glass box. I used one 18650battery from old laptop, a charging module with protection circuit inbuilt,one stepup module to step up 4v to 5v and a 3w amplifier. It's a basic project, but the thing is WHEN I TURN THE SWITCH ON(AMPLIFIER POTENTIOMETER IS OFF) I SEE LED BLINKING ON BLUETOOTH MODULE, MEANS IT'S WORKING ,THE CIRCUIT IS OK. THE MOMENT WHEN I TURN ON THE POTENTIOMETER ON OF THE AMPLIFIER THE SPEAKER JUST SOUNDS LIKE "TICK" AND BOOM EVERYTHING SHUTS OFF. I TRIED TO MEASURE THE VOLTAGE COMING FROM STEPUP MODULE SAYS "0"V. SO I PLUGGED A CHARGER ON CHARGING MODULE AND THEN TRIED TO TURN ON AND FIRST 2 SEC SPEAKER MAKES SOME SOUND AND IT TURNS ON AND PLAYED SOME MUSIC, IT WORKED GREAT. THE THING IS WHENEVER I'M TURNING ON THE AMPLIFIER VIA POTENTIOMETER OR THE POTENTIOMETER IS ON AND I SWITCH ON THE POWER FROM THE FIRST SWITCH THE POWER CUTS. SO WHAT'S WRONG WITH THE SPEAKER. PLEASE TELL ME :(

TDA7293 isnt turning on Answered

I recently bought some TDA7293 chips figuring they'd make nice amplifiers, but when I tested one just now, nothing happens.  It doesn't even seem to take any power in, it doesn't heat, hum, smoke, pop, or anything else, and I've checked the wiring a bazillion times.  (12, actually, but that should be enough)  I'm using this circuit :  http://sound.westhost.com/project127.htm   on a +-12V supply, which is the minimum specs according to the datasheet.  I can't use a higher voltage because I don't have a higher voltage power supply right now (the 24V one I had hummed enough to destroy one of the other TDA7293s I had), and I want to remove all other possibilites before buying another split supply.  It has a little static when I take the power off, but leave the input connected, but it turns compleatley off if I apply voltage (but doesn't click or anything, there is no voltage going to the speaker at all.)  Any ideas?

Dell computer question?- not turning on

I have a Dell dimension 2400 that while using it turned off and never powered back on. It was raining that day and I was on the computer and I heard what it sounded like a spark and I kinda saw it too behind where the computer case is(light was off so I saw like a small spark on the wall). I have the computer on a protected surge power strip. This happend before a month before and it was fixed with a new power supply. It didn't turn on also the next morning and it was raining also in the night. I'm thinking a voltage spike cause it .So this time I put in a new power supply and it wont turn on. The power supplys both work(new and older one). So what could it be that is causing it not to turn on? Anyone ever had this problem before? There is a green LED inside that turns on when pluged in but thats it. The power buttons LEDs don't turn on when pushed to power on.

Turn dial to generate pulses

Here is my proposal. I'm building a pan/tilt unit. I plan to have a 200 step motor attached to a 20:1 worm gear, (the latter is needed so it will 'lock' in place, and not be solely reliant on the motor's holding torque.. So in order for the output shaft to turn 180 degrees needs the worm gear to turn 10 times. In turn the motor must do 10 revs, which would need 2000 pulse steps. It's the pulse generation that's proving difficult. Whilst a 555 timer could generate pulses, I want it to be 'mechanical' For example, if I turn the knob 90 degrees, I want to create 1000 pulses, (45 degrees creates 500 pulses) and so on, so the knob matches the physical position of the camera. If I turn the knob 180 degrees in 1 second ... the motor will turn 180 degrees in 1 sec. If I turn the knob slowly, pulses will be generated slowly, and the camera/motor will turn slowly. My idea at present is some sort of optical encoder ... but that would need 4000 divisions on the wheel!! Or - a 1024ppr wheel with a 1:4 step up gearing ... but such encoders are several hunderd Pounds!! And I would need two of them!! I have software that will allow me to print an encoder wheel, but resolution will have to be 'course' since it will use an LED / transistor, so I suspect around 64 divs. I purchased a RC servo, wondering if I could remove the motor, and turn the output shaft by hand. Couldn't be done. I've also considered 'planatary gears' in reverse to 'step up' the revs ... but I cannot locate any 'hobbyist' versions other than the Tamayia type. Also briefly looked at RC servos, but having done the maths, it would be impractical to get the output to move (say) 0.1 degrees as the motor would only move about 1/4 of a rev and have no torque!! (One option may be to make it continuos rev, and place a feedback pot externally.but again, moving 0.1 degree around a pot would create minimal feedback) Incidentally, 0.1 degrees is the stepper resolution 180 degrees / 2000 steps Anyone any ideas? Bearing in mind that the speed of the pulse train is dependant on how fast the control (pot) is turned, and also matches physical camera position. Encoders are preferred option as it's then possible to electronically guage which way the motor is turning. If electronic, here is (sort of) what the circuit would need to compute. (Sample and hold?) Moved from 0 to 45 degrees in one second. That degree of movement needs 500 pulses, thus need to generate a pulse width to get 500 pulses in 1 second timescale. ** This is just to give an example. The actual sampling rate would be much faster. If it was a 'slow' 1/10th second, in the above example it would check every 4.5 degrees, and generate 50 pulses in that time scale.
