Finished my first build, it turned out prettier than I expected honestly. I got a diodeless kit because I had never soldered anything before, it was quite a fun learning experience. Also my first mechanical keyboard, I'm really enjoying the feel of the keys (Kailh sunset).
I was really worried about adapting to the column-stagger, I've only used the regular row-stagger before, but after one hour of practice I was already typing at about half my normal speed, so I'm pretty happy.
I do feel that I need wrist rests though. not sure how to fix that yet.
I've been using a 5 column version for a while now and have enjoyed it. The biggest issue is that the blackpill controllers aren't always recognized fist try. It looks like you're using a different controller- what is it?
