Been seeing some #deej https://deej.rocks/ projects lately and wanted to make one, had a dig around in my parts bins for interesting stuff, A double slider from an old tape deck for main volume and browsers, 3 pots for music, voice chats, and everything else. 6 switches with LEDs are used as a macro pad (had the idea to make one for a long time) and an Atmega32u4 PCB to do serial, mouse and keyboard at the same time. With smart management the switches can do a lot of different things.
