Re: My first telly TV22
I have gathered the bits for my LOPT rewind
1. Arduino Uno with stepper motor shield
2 stepper for winding axis
3 stepper with lead screw for traverse axis
4 0.2mm magnet wire
5 transformer tape
The rest of bits I can 3D print
There are quite a few arduino based coil winding machine projects on the web for inspiration
My first step will be to set up the existing primary coil on the stepper motor and do a controlled unwinding and use the arduino to count the turns for me , I could do by hand but don’t want to lose count
I will 3D print a suitable bobbin to wind the primary onto and exactly reverse the process with new wire and a layer of tape between each layer.
That’s the theory at least!
Will video as I go and if successful post it on youtube
