The Keyboardio [1] Model 01 is an open hardware success story (Figure 1). First shipped in late 2017, it has gone on to ship thousands of units, as well as developing a small but enthusiastic band of users and volunteer developers. However, this success did not come overnight.

"For quite a while," he remembers, "I carried a Microsoft Natural Elite keyboard in my backpack. I tended to go through three or four of them each year." Sometime in 2011 or 2012, "I discovered that there was an online community of folks who made their own keyboards. Somewhat naively, I figured I'd take a month and build myself a keyboard. Seven years later, my wife Kaia and I work full-time on keyboards."
