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.

Hi Dave,
Great project. Here's one I made. I plan to build a base inspired by Paolo Bacigalupi's "Drowned Cities." Sort of a post-apocalyptic gaming system.
I will post a picture once it's done.
Cheers - Mark

Thanks Dave. I used enamelled winding wire which lets it have that coppery look and remain insulated. Although all of the copper wires are separated, they are quite close in places, so the risk of shorts is reduced.

That looks fantastic!
I'd missed seeing this episode, it looks amazing, as does your enamelled wire version. I think they should be framed behind clear acrylic, with holes cut-out for the buttons : )
