I've started to build myself a Levinson (40% ortholinear split keyboard) and I'm really enjoying the whole process. Except soldering burns maybe.
Soldering diodes and resistors on the Levinson PCBs was the easy part. I think I've finally understood how to use a soldering iron (and I also think the one I use is crap).
@lectronice looks like a lot of fun, I've wanted to do something like this
@tsu It's definitely a lot of fun (and confusion, since it's a split keyboard you have to mirror everything on the other side of the second PCB and it's a bit strange at first.)
