I've wished I had an IR camera to debug circuits. Two months ago I got one. Today is the first time it helped me out. The USB-A on my laptop have 300mV on them, not 5v. I was expecting a shorted capacitor or a bad diode or something. But I found this part […] [Original post on leds.social]

I've done my smallest hand soldering yet to test a new I2S microphone now that the popular ones are EOL. Probing with a multimeter and it seems there are no shorts. I don't think I'll get to fully testing it tonight. I need to add a 1.8V LDO and level shifter.

I miss the packaging from RadioShack/Archer electronic components. It's handy to have a little datasheet of the essential bits as part of the packaging. I have a whole Internet of datasheets readily available, but that's still an extra step. I'd pay a little […] [Original post on leds.social]

Today, I used the new iron for some heat inserts into PLA, which went smoothly. Fortunately it goes down to 200C (I used it at 220C). (Though another bonus for the HS-02 & TS101 over the T90b is that they go lower still to 100C & 50C.) Then after the PLA […] [Original post on leds.social]

My favorite LED project out there this year was illumicone.com - a returning piece. They use magnetic sensors to reliably detect rotation on various wheels despite the dust. And the interactions drive the display. #BurningMan2026

Inspired by someone we saw two years ago, I setup some LED "pebble" strands with #WLED and a mic for a friend to braid into their hair. Combined with LED earrings, and a coat that she recently upgraded the LEDs on, she was very glowy and very rainbow/RGB on burn night. #BurningMan2026
