Coil Winder Build Using Arduino & Stepper Motors

- Sharing my prototype coil winder design that I built and used to rewind a vintage PEPCO power transformer for my Jackson Bell Model 556 receiver. The simple design leverages Arduino and Stepper Motors.
The as-built BOM and two Arduino sketches can be downloaded from the Coil Winder folder at: drive.google.c...

Don - this is phenomenal... I love how you use new technology to restore old technology. That is a perfect marriage.... Well done my friend.... Very proud of you
I really appreciate your kind words Ron. Merry Christmas and Happy New Year. Best, Don
Don this series on rewinding the transformer, along with your calculations are priceless. Your attention to detail, and teaching us is truly appreciated!
Thank you so much for your kind words. The rewind provided a learning opportunity for me and challenged my skills/abilities. Thanks again and all the best. Don
I spent years as a young man operating coil winders way back before I got my elect. degree. I really hated that job but now seeing what you have done here gives me a bit of enjoyment to see Dons robot doing it instead. Outstanding build Don, your way above normal classic radio entusiasm. Your more than that. You are truly.... an inventor.
Very neat Don. Always great to see you tackle jobs most folks walk away from. I have hand wound a few transformers before but this would make it much better. Thanks for sharing.
Thank you Buddy, the hobby presents a learning opportunity for me and stretches my abilities to the limit and beyond at times. Merry Christmas and Happy New Year. Best, Don
Don, great job!
Thank you Josh. Merry Christmas and Happy New Year. Best, Don
Very nice design. Thank you for sharing the diagrams and description.
Thank you Robert. Best, Don
Your ingenuity is truly amazing Don, what a great piece of equipment to have.
Thank you Jim. It worked well and a few tweaks down the road should add value. All the best. Don
Nice work!
ya know, when i was researching the same project, i was very interested in how sewing machines kept tension and using a spring tensioned arm with software to account for the four corners of the block or square stock to compensate the wire to keep from snapping as it wraps around sharp corners. it turned into a large project with no end in sight.. :/
Interesting. I considered a solution similar to your idea, but decided to try the conical bottle caps with locking nuts. I was fortunate not to break the 36 AWG magnet wire, but this is an area the winder can be improved. Best, Don
Thank you. All the best. Don
Thanks Don! Another winter project. Hopefully this will help me with my RCA rebuild.
Hope it helps Ted and the RCA rebuild is successful. I plan on publishing the data for the transformer rewind after Christmas. Take care and thanks again. Best, Don
Very nice...
Valdir - thank you, I appreciate it. Best, Don
This is great! I learn a lot from from your videos and appreciate the time and effort you put into them. I hope you and your loved ones have a great Christmas and a happy, healthy and prosperous 2022.
I really appreciate your kind words. Merry Christmas and Happy New Year to you and your family. Again, thank you for watching and reaching out. Best, Don
Nice work, and very informative. Thanks.
Much appreciated John. Best, Don
nice great job
Much appreciated. Best, Don
Wow! I would've just waited for one to show up on eBay. And waited...
Vic, glad you found it helpful. All the best. Don
Brilliant!
Robert, much appreciated. Best, Don
Nice job on the Nell and winder. Is a lattice / pi version next? I have the definitive book "Coil Winding" by Wm. Querfurth published by Geo. Stevens Mfg Co. Understand the text mostly. Just can't get the steppers to cooperate.
Thank you. When another I.F. Transformer fails, I might try tweaking the “LS” Stepper Driver motion to achieve the lattice / pi version. I’m assuming you saw my Honeycomb Coil Winder at:

Hello Don. How much do you think this would cost if you had to buy all the parts? Its a real ingenious build sir. Best regards Mark
Great build Don. I don't have Arduino programming ability, yet. One thought is what is the difference between a parallel wind and cross wind (X)? Is one more efficient than the other?
Thank you. Definitely a difference in the winding and performance. My design is best for multilayer that is used in field coils, audio, power transformers, etc. Universal or Progressive (X) type windings reduce distributed capacitance and increases the Q-factor of the coil and best for RF coils operating at 20 kHz or greater. I built a very basic Honeycomb winder that I used to wind some IF Transformer coils that works pretty well. I’ll edit this comment and put a link to the video for reference. The Honeycomb winder was later phased out as the Universal and Progressive winding techniques provided better performance. Best, Don

@@RestoreOldRadios Thanks Mr Don. The reason I asked about the X wind is that I have seen some I.F. transformers wound that way.
@@RestoreOldRadios I will have to start the research on coil winding. Sooner or later there will be no option for repairing a radio that is in front of me.

Here’s a pdf for the book I noted: www.benmook.com/tech/documents/Schematics%202/Coil%20winding%20&%20catalogs/Coil%20Winding.pdf
Please give me code
The link to the code is in the video description. All the best. Don
