Here’s the final style of Glowie we’re making! Shooting stars and flames! These fun animations draw attention without being too distracting, and their battery life is double the solid Glowies, so around 20-24 hrs on a single charge. #glowie #alpenglowie #ledjewelry #mfba2025 #makerfaire

Terra Luna by Quixotic at the Overland Park Arboretum did not disappoint, as usual. Art, music, performers, lasers & LEDs. vimeo.com/742747614

Bzzzt! Glowies are powered by a tiny LiPo battery and rechargeable! Stay tuned for more incredibly fun designs coming to Maker Faire Bay Area! #mfba2025 #makerfaire

I have something to say about the PC817 Opto-Coupler

My friend, @chipperdoodles.bsky.social, has launched their Crowd Supply campaign! www.crowdsupply.com/chipperdoodl... If you're interested in badge life and want power delivery figured out for you, consider backing this project and creating your own faceplate as a great starting point.

I know I'm late to the @architeuthisflux.bsky.social Jumperless V5 party, but this thing really is brilliant in every way! 🤩 Get yours: www.crowdsupply.com/architeuthis...

Light yourself up at Maker Faire Bay Area and Lambtown this year - we’ve got some fun new LED wearables in the works! #mfba2025 #wearables #ledjewelry #lambtownfestival2025

Anyone interested in ~hexagonal Fibonacci LED tiles? Each tile would be unique, but could be combined together to form large displays of various shapes and sizes. These would be ~20cm tiles with ~200 SK9822 LEDs each. Six rings would be 91 tiles, 2.2m wide, 18k pixels, and could draw up to 2.7kW. 😁

Hell yeah, its a tool-changing 3D printer fight! www.tomshardware.com/3d-printing/...

Yes, I'm still alive (and the cake was fantastic)! Meet Caroline, my experimental low-cost robot arm - swinging a camera today, on the way to running my Studio tomorrow. www.youtube.com/watch?v=rKyJ...

Want to make a wearable LED project? We’ve got some new helper boards in the shop! Our LED Buddies make it super easy to add USB power and an Electromage Pixelblaze Pico to any project with addressable LEDs, particularly the flexible Pebble-style ones. www.alpenglowindustries.com/collections/...

Curious what it takes to write 3D patterns for #Pixelblaze by @bhencke.bsky.social? I've written up a tutorial: www.evilgeniuslabs.org/tutorials/pi... Among other examples is this rainbow-colored 3D Perlin noise on a three dimensional #RGB #LED cube. Get your own cube: lectronz.com/products/led...

I did it! I made a video game. Introducing Star Captain 32767, a retro-arcade shooter with rogue-lite elements, inspired by games like Galaga and 10000000. The game is free, but if you enjoy it I would really appreciate a small donation! aaronpendley.itch.io/starcaptain

New episode! @johnpark.bsky.social joins the show and shares floppy disk MIDI boomboxes, @todbot.com shares AlgoRave - live coding music, @paulcutler.org shares the rp2350 as a mini-computer (with the Adafruit Fruit Jam released days after recording), and more! www.thebootloader.net/blog/2025/08...

I made another little thing. It's a particle sim driving a voronoi fracture. The results then get some uvs and topology love before being shipped off to the displacement algorithms and rendered. Made in Houdini and rendered in Blender. #houdini #blender

I've played less than an hour, but I'm really enjoying Primal Planet so far. "a metroidvania with survival & crafting elements, a pixel-perfect aesthetic & action-packed story, all on a lush planet filled with dinosaurs." www.gog.com/en/game/prim... store.steampowered.com/app/2350270/...

The tiny one inch (25.4mm) Fibonacci128 perfectly fits in the front chest plate of Dummy13 printed at 200% scale. I'm working on a modified 3D model with a cutout for it in the front and a "backpack" to fit an @adafruit.com QT Py and LiPo BFF. 1" Fibonacci128: lectronz.com/products/inc...

It's been a while since I promoted my own and others' Maker/Electronics Starter Packs! bsky.app/starter-pack... bsky.app/starter-pack... bsky.app/starter-pack... bsky.app/starter-pack... bsky.app/starter-pack... bsky.app/starter-pack... bsky.app/starter-pack...

Finally revisiting "Fibonacci256 Expanding"! I found a few working LED PCBs in my stash, finished the #lasercut acrylic enclosure, got it working with #PixelBlaze by @bhencke.bsky.social, submitted for approval on Lectronz, and up for sale soon! www.evilgeniuslabs.org/fibonacci256...

Fibonacci256 price drop! I messed up when copying the listing from Tindie to Lectronz. It's fixed now, resulting in a $120 drop in price. If you'd previously taken a look at the listing, you might want to take another look. Sorry about that! 😅 lectronz.com/products/fib...

Instead of pixels being only off or on you can use a wave function for brightness. The period of the wave is each pixels' radius, you get a much smoother pattern. The #Pixelblaze code is short & relatively simple: gist.github.com/jasoncoon/db... Get your Fibonacci256: lectronz.com/products/fib...

Carl Sagan's "The Demon-Haunted World: Science as a Candle in the Dark" was literally life-changing for me. It completely changed the way that I saw the world.

I just made a yearly donation of $60 to my local PBS station and received a subscription to their streaming service Passport. It includes all of their shows: Nova, ACL, News Hour, Bob Ross, Test Kitchen, all the Ken Burns documentaries, etc. Watching the DaVinci doc now. www.pbs.org/passport/lea...

In disc phyllotaxis, like Fibonacci256, lighting every N LEDs from the center produces a pattern. If N is from the Fibonacci sequence a spiral (or mesh of spirals) is produced because the divergence (angle of succession in a single spiral arrangement) approaches the golden ratio. evlgeni.us/f256hdr

New episode of The Bootloader is out! @todbot.com and @paulcutler.org chat about tariffs (with some occasional swearing), desoldering tricks, a classic arcade game, and more. Find the show wherever you get your podcasts or visit www.thebootloader.net/blog/2025/06...

Today I'm reworking a Fibonacci512 using the same technique as the F1024 from yesterday: isolate dead pixels with a jumper wire, desolder using an aluminum shim and lots of flux, and replace with new pixels.

I haven't ordered new PCBs lately because tariffsarebullshit.com so I tackled my rework pile. I had enough to build a Fibonacci1024 but one needed rework. I used a thin wire to jump the first dead LED, which didn't light the rest. So I jumped the last lit LED which ended up being the culprit.

I am so excited for you all to try out the new HackRF Pro! I've been hearing all about the work that has gone into this product from my old team for a while now and I'm so impressed. I'm sure you'll find a few new features (compared to HackRF One) that you'll love.

This Khamsa Umm is beautiful, thank you @chipperdoodles.bsky.social! 🤩

This is so long overdue. Over the past eight years I've watched the Fusion and Eagle commercial yearly subscription "legacy" price climb from ~$200 to $350, then $450, then $500. The non-legacy price is now $680(!?). I should have switched to @freecad.org and @kicad.org long ago.
