Hey! Thank you for the question. For sure, it's not a polished product and I don't mean for it to be. It works surprisingly well. (I've used it as my daily driver for school)
With college apps and school work, the time was tight. I'd say that was the most limiting. Of course, resource and skill played its role.
I did consider flex PCBs, but I didn't have the time to follow through with all the ambitions (i also wanted an FOC input sigh).
I'm honored that you think my keyboard implementation is nice! I put a lot of thought into it — truly. Oh btw the keyboard works just as well as a solo device. I've used the keyboard more than the computer in some ways. Thanks!
