I ordered two of these to try out an ortholinear layout. I know I'll lose two keys to shift layers but the main purpose is to replace my heavily modified nostromo n52. I made a nice palm rest already but still waiting on most likely a raspberry pico for the joystick and space key. I think a similar project called GOTS did the same but I couldn't justify the price. I've hardwired an iris half before but didn't like it so I reused the pro micro for a different project.
Edit: Here is my nostromo n52 with cherry mx clone switches, a chopped up usb hub and a pro micro. I forget but it has like 14 extra buttons. I had to repair it once and do not want to dive into my spaghetti wiring to fix it again lol. The second image is a WIP prototype of the joystick keyboard attachment. I was unsatisfied with it after the first stain so I made it smaller and sanded it again. I tried to copy the n52 palm rest. Not sure why it's flagged as nsfw lol
