MMPAD
MMPAD stands for "mangkoran MacroPad", built with osu! in mind (lol).
Backgrounds
I've started playing a rythm game osu! to kill time since the pandemic began. Actually, I play osu! because it's the only game that I could ran in my Linux. Then at some point in November, I'm thinking of buying a mechanical keyboard for osu!. But holy f*** they are so damn expensive for my poor wallet. Then I remembered herpiko's UNK and it inspires me to build a custom handwired mechanical keyboard.
Objectives
- As cheap as possible
- Fully customizable switch config (I mean, it's handwired)
- Compact, ideal for travelling (mobile gamer gang)
- Helps me reaching FC 5* (lol)

Pro micro arrived. Unfortunately, I didn't check the port this pro micro used, and it comes with mini USB B. So painful searching
for it's cable adapter. Luckily, my friend has unused yet faulty power bank and I just ripped it for it's micro USB B socket.

Switches arrived. MAAANN this switch thingy is soo small. Brown since never using mech keyboard before, next build maybe blue.
2020.12.02
Plates finally finished. Got to pick them up myself (~14 km from home). The first thing I realized is the switch hole I used here is more suited if you want to disassembly the switch after they are soldered/mounted on the plate. I didn't know this until I mount my switch, placed keycap on it, and pulled the keycap. The switch housing popped off LMAO. I kinda scared, but then I browse swillkb documentation and then realized it LOL.
