ISO Tenkeyless TKL Mechanical Keyboard

thingiverse

## the plan: since the stalks on my Corsair K68 RGB started to wear out, i've been wanting a new keyboard, preferrably handmade, and without a numberpad for extra mouse space. i couldn't find any premade PCBs in ISO for not a stupid amount of money, and handwiring my own is a much cheaper option than getting PCBs cut. ## parts: my first handmade keyboard was shit - it used gateron blues, a (badly) 3D printed chassis [sick68](https://www.thingiverse.com/thing:3478494) and a teensy 2.0. i forgot to buy stabilizers, but the concept was sound and worked. - teensy 2.0 - ~100 cherry MX reds - ~100 1N4148 diodes - 3D printed custom chassis - stripped ethernet cable - costar stabilizers - susuwatari MT3 caps - USB mini B cable ## electronics: a TKL ISO board with a full function row has 87 keys, 6 rows and 17 columns - the way a teensy works as a keyboard is by scanning each row and column to check for connections, so to hook up every key i'll need to use exactly 23 pins. ## software: the teensy 2.0 can be turned into a keyboard controller using EasyAVR. you just need to supply it with a json file of the keymap, and it'll generate a .py file, or a .hex you can flash. I've provided the .hex and the .py if you'd like to edit the layout.
