tuk_tuk – a 42-key katana-stagger in a Minivan case

open source, files on Codeberg

this was a big learning experience, first time doing a proper PCB instead of using yet another Pro Micro equivalent – this would not have been possible without Noah Kiser’s tutorials on Youtube, all the work that went into QMK and Vial, and the ease of JLC’s assembly service (no way I was ever going to solder an RP2040)

shocked and giddy with how easy the whole process was – plugged in the fresh PCB and it went straight into bootloader mode – uploaded the *.uf2 and it worked first time!

• symmetric split-ergo style layout (6 × 3 + 3)
• katana stagger
  • personally find this works really nicely and keeps the feel of an ortho or columnar board
• fits into Minivan case (12.75u × 4u)
• attempt to use as many existing mounting holes as possible (6/7)
  • main issue was maintaining symmetric layout with two mounting points in bottom row
  • personally find the resulting odd gap to be uncomfortable
  • if I do an update, I would remove the awkward spacing and slide the whole bottom row to the left a smidge (resulting in an uncomfortably-asymmetric symmetric layout)
• learning to use JLC’s PCB assembly instead of a Pro Micro equivalent
• providing a proper Vial firmware
  • (default layout is based off Reviung41 layout)
