Microcontroller based inductor winder? Answered

 Is there any way, and I'm sure there is but I don't know how to do it, to make an inductor winder that is programable. Any type of microcontroller brand would work, be it arduino, parallax, pickaxe, whatever. Basically what I would need is a code, and a schematic that would drive two servos, one continuos rotation to do the actual winding and one to move the inductor back and forth, to keep an even winding going. The code would have to dictate how many turns the servo does in order to get the desired number of windings. It can even have to be reprogramed for every inductor from the PC, to keep it more simple. --Thanks         P.S. Sorry if this question was difficult to understand, I didn't know how to put into words what I                           had pictured in my mind...

Arduino or Teensy coil winder - any code already out there?

I am in the process of deciding on a normal 8bit Arduino platform or a Teensy for my coil winder project.A found some interesting projects online, some with the code available too.But I was wondering if someone already implemented more than just winding a coil in such a project?At Krux.org is a nice winder based on a normal Arduino while the Alba winder uses a Teensy already to gain more precision and speed I guess.Misusing some printer or CNC code to be able to generate coils by G-code sounded nice at first but turned out to be more complex than actually required.My goal is actually rather simple despite the size and all, so let me try to explain what I want to be able to do:Have a modular winder setup so basically any winding task can be done with just two stepper motors.One for the spin, one to position the wire.Additions like limit switches and external counters are nice but usually not required for such a task if the the code is properly done.As a basic winder like all the examples out there it should be possible to just enter the wire diamter and number of turns and then push a button to wait for the finnished coil.In theory things like pitch or spacing can be calculated externally and then entered as a fictive wire diameter but of course this would be not user friendly enough ;)For special RF coils it is often required to keep an even turn spacing as well as creating a coil with many layers.So far I have been unable to find any usable code for this purpose that does not require glue, guides or at least waxing the wire.Although this seems to be simple enough, when adding things like a display and counters it soon starts to get messy with timings and steps.Is there anything out there that works properly on a 8bit processor with reasonable speed?Originally I wanted to use an OLED with touchscreen.This turned out to be too much for the timing on a Mega.Without messing around with timers and interrupts it seem a 20x4 LCD is the only option.Even then the refresh must be in sync with the tart of a new turn as otherwise the motors miss some steps here and there.These things run a 3D printer or little laser cutter with ease, so I am definately doing something wong with my approach here LOL

Unified field theory?

I was windering if someone could tell me how to add gravity to the Unified field theory? thanks

Hi I would like to make an automatic feeder for my pigs using an electric motor to control the amount of feed.

I was going to use pvc pipe and a electric window winder motor to open and close a flap at the bottom of the pipe. Can anyone help on how to automatically trigger the motor to open and close the flap once or twice a day for about 10 seconds. (open 10 seconds, allows grain out and then closes to stop any more grain coming out again. Any assistance would be appreciated. I dont know much about electronics. Dan

How does one choose the right 100k potentiometer?

I am building a pickup winder... a simple machine that winds hair-thin copper wire around magnetic poles.I need to build a 12V DC geared electric motor speed controller. I bought the following...12V DC 1000RPM geared electric motorLCD punch digital counter with a magnetic proximity switch12V Double-Pole Double-Throw (DPDT) ON/OFF/ON toggle switchDC12V 2A Power Supply Adapter: AC100-240V to DC12V I know that a DC motor controller can be purchased for around $5-10, but since I am brand n00b to electronics, I want to take the opportunity to learn as much as I can by building everything (or as much as makes sense) myself. I found this Instrucable on building a DC motor speed controller. It seems simple enough, however, when I go to the Digi-Key website and look for 100k Ohm pots... there are a lot to choose from. I do not care about form factor. I have no size restraints or aesthetics. I just need a knob... that I can turn... that will allow me to set it to zero, switch the machine on and have the motor not turn at all... then slowly begin to spin as I turn the knob up to 10, and it is spinning at its top speed (1,000 rpm). This is the motor, this is the power supply, this is the counter, and this is the switch that I bought for this project. According to the instructable referenced above, I need: an IRF3205 mosfet, a 100k ohm potentiometer, and a heatsink. I do not yet have the vocabulary to even properly Google "How to tell which 100k ohm potentiometer works with a 12V DC motor..." Can someone please point me in the right direction?
