Recycled vape battery bank
I hate e-waste and I love free things, so when I found an open source battery bank project and already having a stock of used vapes from friends, I just knew I had to make one for myself.
I was already comfortable with electronics in general and ordering populated projects from PCBway due to my VR tracker project, so taking the plans and getting some PCBs made was a breeze.
Taking apart some used vapes was a few hours in front of the TV (wear gloves nicotine residue through the skin is no fun) and prepping the batteries with copper tape was a few more hours.
3D printing proved to be surprisingly finicky with a few sad print failures, probably down to the colorful filament.
Wiring the whole thing together and seeing it light up was very satisfying in the end.
