Found a 60x60 LED panel for 20dkk in the thrift store last week. Found an LED driver in the trash a couple days later. Just had to adjust the output power and change the power connector. Who knows, dali control might be broken, but I’m not living in an office. Think it’s gonna be my new work desk light.
I found a Rollei action camera in the trash. Seems fully functional except it won’t take a charge. The shell clicks open after removing the four visible screws at each side of the camera. The camera has two lipo flat-packs wired in parallel and soldered to the board. Only one of the cells has a protection circuit, the other’s wired in behind it. Both cells have swollen significantly.
