Bifilar Pancake Flat Spiral Coil: Winding & Mounting Process (speaker wire & acrylic sheet base)
Channel: cold3lectric
Date: 2021-11-08

Here's a walkthrough of how I like to wind my Bifilar Pancake Coils - I like having them zip-tied to a rigid acrylic base to be able to fix them in place for stacking, and for mounting connections & whatever else so that all stays level. This way I avoid adhesives/glue/tape, which may contain trace water content (although probably trivial at gloriously low bifilar frequencies, often below 100k cycles/sec).

I have attempted to distill my approach into a quick & accessible informational/teaser here. However, I learned about bifilar stuff from Master Ivo and he has tooooons more details about Bifilar Pancake Coils on his channel, so for more info definitely check his channel out - you'll find dozens of gems:
