I missed my monthly "don't buy a resin printer" meeting with @jumperless.org because I was hand-soldering a 3×2mm WS2811 IC to a flex PCB. If you want a Neopixel with colors other than RGB, turns out you can just make your own by having a long enough manic episode.

@settinger.net missed his monthly appointment to tell me not to buy a resin printer so I did. These things friggin' rule (for the kinds of things I tend to make) But I also see why the washing and curing stuff is such a big deal, my tupperware full of vodka and 3 UV flashlights aren't gonna cut it.

Petition to give the LA Metro A Line a secondary name, the "Jonathan Gold Memorial Line," so we can all go back to calling it the Gold Line and end this song-and-dance where I have to suss out how long you've lived in LA before I know which name to use around you

This has been a quixotic quest for no reason other than to see if i could do it, but I did do it: I've created a ceramic circuit board with copper traces that I can solder components to. Here's a little astable multivibrator circuit running on stoneware.

RP3A0-AU: Raspberry Pi Zero 2 W SiP - now with bottom pads! Thanks to @settinger.net for sharing and making this the 154th macrochip design! See them all here: www.evilgeniuslabs.org/macrochips

I made a box to keep my lead-tin solder isolated from the other gear in my traveling electronics kit, and uh,

Updates from the Cool factory

#39C3 is about to be very.. Cool

Ok but seriously, what am I going to do with a nearly 4-foot-tall (114 cm) Cool S, I've run out of wall space for such a thing. Do I let it into the blank wall space I keep for professional video calls? Do I mount it on the ceiling over my bed??

We are officially seeking applications for TALKS, WORKSHOPS, EXHIBITIONS, ART and PERFORMANCES for OHS2026 May 23rd and 24th at TU Berlin! Submit yours today: forms.gle/kDGTVqfVAZXm... Applications due December 21st!

Putting on a hard hat and steel toed boots, consulting the cyanotype blueprints for this elaborate construction project

....oh right, I completely forgot about these until someone asked me about them at Supercon and then a lot of people asked for a set.

A silly idea that turned out well! Most flex PCBs are cut by laser, not milled, so you can make perforations by adding incomplete edge cuts. These disks are for cleanly joining LED strips at different angles and different radii, and they break apart with just my fingers, no other tools.

I wrote a little comic about #opensource hardware and serviceberry foraging! I'll post all the panels here, but you can also read the whole thing on @archive.org : dinalab.us20.list-manage.com/track/click?...

Honeycomb pattern, one of the preloaded ones on a Pixelblaze LED controller by electromage @bhencke.bsky.social

I made a really cool LED wall project for my house last week - spruced up an ugly black fireplace with 1035 LEDs and a Pixelblaze LED controller. Check out the full story and project progress on mastodon: mstdn.social/@alpenglow/1...

I made this specifically for @settinger.net but felt I couldn't deprive the rest of the internet of this nonsense.

I have enough pieces to fill an 11×14" shadowbox now. It's all coming together 😁 I'm still a bit worried about fit and precision (or lack thereof) on these tiles, but gosh they fit nicely so far. Need to get more hot glue though.... So that's *two* things I had to buy in order to complete this.

I made some high-temp silicone molds out of Mold Max 60 and have begun casting Moroccan-style zellij tiles out of my years of accumulated PLA scrap. They are very fun to play with.

Another pillow demo, running different patterns (there are 20 options), with different music. This was part of the #makergiftexchange that I did with some friends, and the first sample is shipping out today to @geekmomprojects.com

The stickers have arrived, thank you! #makergiftexchange They're even more shimmery in person - I look forward to using them to encourage people to "do it, coward!" (including myself)

Video demo of my lighted pillow

Introducing my new light up pillow ...

Our #makergiftexchange happened on Wednesday, another moment where I'm bowled over by just how creative my friends and colleagues can be. My contribution was an inside joke. Did you know that, in Shenzhen, they'll let you print whatever you want on those shiny holographic security stickers?

SO. I’m developing a kit because I have a feeling that maybe other people might like to add LEDs to their crochetwear? What do you think, would you crochet with LEDs? I’ll do another post soon showing you the inside, maybe another little vid. More shout-outs to my electronics homies -

I’m so excited that I can finally show this to you all! I’ve been working on it for a while, as part of an annual white elephant #makergiftexchange that I do with some friends every year. This time I went for the full cross-over and made a #crochet LED hat.
