Recently 0x0000ff has reached out notifying me that the guide does not completely work for people using the Wayland display server in place of X.Org , as sending keyboard signals works a bit differently there. Fortunately they were also kind enough to provide the list of changes needed as well as the relevant
I was in need of a logic level shifter so I could easily interface to an in-circuit low voltage EEPROM with my Beagle Bone Black board via a breadboard for some debugging and poking around. While there are a few existing solutions out there, not all of them were in stock due to the recent chip shortages and supply chain issues, and others I did not like. So rather than keep waiting for availability on one of the electronics websites, I’ve decided to dust off my EE degree after nearly a decade, and build my
