I bricked then recovered my reMarkable 2
Let me start by saying that the reMarkable 2 is a great device.

Raspberry Pi KVMs Compared: TinyPilot and Pi-KVM v3
In a strange coincidence, the authors of TinyPilot and Pi-KVM both emailed me within a week of each other and asked if I'd be interested in one of their KVM devices.

A different kind of keyboard
I’ve always been attracted to chording keyboards in theory, but I lack whatever childhood musical training is required to wrap my fingers around them. So I made something else: an arpeggio keyboard. Peggi is an eight-key keyboard that fits on the back of your phone. While chording keyboards require you to press…

Monitoring my home's air quality with AirGradient's DIY sensor
A few months ago, I found this Hacker News post about the AirGradient DIY Air Quality Monitor. I had already been considering buying an AirThings Wave Plus sensor to monitor my home's CO2 levels, but the high price and limited 'ownership' of the data coming from it turned me off. So I built two AirGradient DIY air…
