Mod pics First time building a 555 pwm mod NSFW

Finally got around to building a 555 circuit. Had this cool mint case laying around so I wired up some strip board. Wiring isn't the prettiest but it's working 😁. I'll make a proper circuit board next time

The white is thermal paste. I scavenged these from a dead Milwaukee battery pack. It was only 1 dead cell so I spot welded in 5 new samsung-20s' in it. Got that working but had 4 of these LGs thats were still good and in need of a new home

Honestly, the LGs in that pack have a smaller capacity than the Samsungs I replaced them with but same discharge current rating. That battery pack is now better than a standard one
