I decided to build a new winder for my custom bass pickups. My old one is quite a pain to use, I wound some great pups with it but it was just a hassle to set up and use each time which made the task dreadful. This winder will be almost fully automatic and is a breeze to use. With this new setup I will get better built, consistent sounding pickups. The winder consists of a 24volt Dc motor that has two speeds fast and way too fast. To control the speed I use a pulse width modulation speed control that is really smooth and offers superb RPM control. To use it you simply turn a pot to turn the speed up or down or off Counting the turns of the spindle is handled by a Honeywell Bipolar Hall Effect sensor that sends a pulse per revolution to a Veeder Root preset counter. Because the sensor is Bipolar it needs both a north and south pole to pull in sequence before it will trigger, I choose this setup because I wind with my bobbins charged (neo magnets) The bobbin will not effect the sensor because only the south poles face it. The preset counter will kill power to the DC motor via an internal relay at any predetermined count. Thanks to Will Ramirez for the preset counter tips! I've also got an automatic transversal worked out for it. Basically all this does is move the wire back and forth on the bobbin. It sounds simple, but theres a lot more to it. The transversal consists of a linear stepper motor, Easydriver stepper motor driver board and an AVR microcontroller. The AVR tells the Easydriver when to move the motor and in what direction. The Easydriver applies the higher voltage that the stepper motor needs at the AVRs demand. The amount of different things the AVR can do is simply amazing. Future plans include synchronized transversal and automatic motor speed control. I had a lot of help on this part of the build so I can only take a little credit, the programming code needed to make the AVR jive is way above my skill level.(THANKS MATT!!!) Everything is powered by a converted pc power supply. Why? because I've got tons of them The supply has several outputs of 3 volts, 5volts, 12 volts, 24volts versatile enough to handle the whole outfit very nicely. NOW THE VIDEO! This was shot during the mock up so all of the winders guts are showing and not everything is mounted as it should be yet. Its kind of ghetto to say the least. I can assure you that I do not plan on using it like this. Everything will be buttoned up and out of site when complete. I also have a guide/tension system Im working on for it. Ill post another video when those are done. Please feel free to comment or question..
