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]

So far, I really like the T90b. It heats much faster than my Hakko FX-888D. My main reasoning for the T90b, is that some people have power negotiation problems with the HS-02, and like the HS-02, it has a cap, so I can safely cover it. It also has a motion sensor to auto-sleep. I really don't […]

Many years ago, I bought a 12v / 3S soldering iron with an XT60 connector for $6 for on the for on the go use. It claims to be 30W, but it has a very laggy temperature sensor, and usually uses 10-15w. It has been extremely handy. Though it really can't handle heavier things. So I recently […]

Finally finished my 1st roll of Lucky 200 film in my uncle's camera!!! The film went through the checked luggage x-ray scanner at the airport, so I was worried it was messed up, but actually, it looks pretty good! Makes me wish I'd put more effort into the photos oops

@lazy-cameko.bsky.social Cameras exist that span from UV to IR? IR has been tempting me but more in the sense of FLIR for checking electronics.

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

@ct depends on consumer perception. I was more reluctant to buy things with lettuce. Even if I know most lettuce is fine, I'm not sure which isn't. From my data point of one, demand was down. So if supply drops, but demand drops more, it still works out as lowered price.

About two years ago, I was trying to get concurrent output for several LED strips working in #rust on #esp32 using the RMT peripheral. I got it working kind of ok for two outputs, but some switching overhead in embassy made that the limit. Last week I figured I'd try using the "LCD" output on […]
