@samuelclay - I’m most definitely not knowledgable enough to hack this together, but I was looking for possible ways to keep my TurnTouch charged without a constant stack of CR2032 batteries. Since I’ve already got a 7.5W WPC Qi-compliant charging pad, I wondered if there were some really tiny ICs and components that could be brought together to make it possible.
What follows is a bunch of links to components and some examples (a lot are from of Texas Instruments’ product pages). I was thinking a relatively straightforward swap for a rechargeable LR2032, but maybe a move to a small Li-Po cell would give better power density.
I’m sure someone with the expertise would at least have fun trying.
