Been thinking of doing this for over a year and finally got round to it. Found parts. Spent hours soldering, lubricating, stuffing with foam and programming QMK. So happy with the final result. It's a joy to use.
Gateron yellow switches. YMDK PCB, backplate and case. Ali Express keycaps.
It's a budget build and none of this is high end......but it has still worked out really well.
If you like tinkering and creating then it's also worth checking out DIY perks.
Also, there's another computer peripheral I've made in my post history if you're interested. It's a fighting gameleverless controller that I made from scratch.
