Retro Gaming Handheld Without a PCB

Dave is a big fan of freeform soldering styles and made a tiny skeleton handheld. As the wise Ben Heckendorn said years before, Dave too tells everyone to collect spare LED legs. "Don't throw them away, as they might come in handy one day!" - or they get stuck in your maglock sockets. Here we need them to connect an Attiny85 with some buttons and an I2C display. |
