I've been working away at this little guy after reading jwz's rant on the UHK over at [1](Copy and paste that link, referrer shenanigans). The main takeaway being that for the name UHK, it sure didn't go down in Vim. So I've tried to make a comfortable keyboard that minimizes strain on the fingers that come from banging on a keyboard all day :)
The I2C bus routed to every switch is the fun part in my opinion. If you can find a device, with a bit of code you can bodge it into your keyboard!
