Retro Gaming Handheld Without a PCB -- Episode 384

Retro Gaming Handheld Without a PCB

element14 presents | davedarko's VCP Profile | Project Videos

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.

Attention: The Attiny85 must be set to 16MHz, although it's out of spec, that's what the games are programmed for!

I found this library not working for most of the Chinese display out there. The original author of this library, Neven from tinusaur team has actually updated the implementation due to this issue, but the port from Defragster still has the old code and people may find it hard to get the screens working. If anyone is facing the issue, please use the updated and fixed library from here
It's a drop-in replacement and does not require any code modification
