Discipline 65

65% DIY keyboard kit using only through hole components. Open-source design by CFTKB.

Built 2020-03-12

Sound Test

For my second board, I got a little more ambitious. I was keen to do more soldering and was drawn to the unique look of the Discipline 65, with it's internals laid out beautifully under an acrylic guard in an open-case design.

The official kit seemed to be perpetually out of stock at the time, so I took it upon myself to source the parts. (Yay for open-source!).

Soldering all the components on

Assembling this board was a little less straightforward than the first one, owing to the increased complexity of the design, and one pesky little USB port that called for some drag soldering. Thanks to a pretty detailed build guide by CFTKB, nothing caught on fire (so far).

AVR Hello World territory

The brunt of my troubles came from flashing the blank ATMega32A chip that powered the board, but after a few hours of head scratching, environment reinstalling and Stack Overflow, my first completely DIY board was alive.

Soldering switches and testing the stabilizers

All in all, it was a really fun build, and definitely brought my attention onto the hundreds of open-source designs out there. Again, pretty bad for my wallet, but sacrifices must be made in the name of progress!
