← Bench notes 6 October 2026 From the bench Thought my old computer had a bad power supply, so I replaced the PSU. My first time swapping one. Turned out the older machine just didn't like all of its cores getting slammed.for species id.....oops. Newer Slapped together a "stop backing up" sensor for my partner, using an esp32, an old ultrasonic sensor, and spare neopixel strip. Anything within a certain distance of the sensor makes the rainbow light party. #esp32 Older Painted a turtle print to give my sister a smile. Found out afterward I should have painted the lines white, not black. Doh. #3dprinting ← all bench notes
