These little guys have been on stuff like aliexpress for a while, they're VERY cool

Frequently incoherent. Hater. Not interesting. Very boring.

I only found out about them because I saw people using them to make their battery powered mice rechargeable like this (not my pic). I think I remember some people 3d printing shells and routing a small cable so it could be charged from the front too. They're really handy for mods or rechargeable conversions  

Don't really use mine anymore though

oh that's smart af

i see what you were saying now @velvetblue.eth haha

interesting that they've been out - first i've heard of it tbh
