I needed a project yesterday, so I compiled a spreadsheet of all my mech boards (and pending group buys). Aside from being sobering to the point of making me want to hide all my credit cards from myself, I noticed that I have pretty good coverage of the various kinds of switches and layouts (40%, 60%, TKL, full-size, Kinesis, Ergodox). I’m starting to dip my toes into the world of building kits, and am curious as to what people’s favorite “weird” layouts are. I’m particularly interested in layouts that really push the envelope in terms of having the fewest number of switches possible (including things like BAT chording keyboards) and stuff that really takes advantage / requires the advanced features of flexible firmwares like QMK.
So – what are your favorite split designs, or one-handed keyboards, or ergo designs? Especially, which of those designs are available as kits for enterprising makers?
