Hello friends, family, supporters, and maker community. I've had to make the difficult decision to shut down Alpenglow. The short story is that we aren't making enough continuous sales to cover our shop space and employee costs. More info: www.alpenglowindustries.com/blogs/all-bl...

It features cool stuff by us, @architeuthisflux.bsky.social @californiasteam.bsky.social Steph Piper / Maker Queen @bhencke.bsky.social @evilgeniuslabs.org @drc3p0.bsky.social and has links to all their sites & socials for easy shopping & following. Support small creative electronics businesses!

It's the time of year where I get to show off all the cool things our friends make! Check out the 2025 Alpenglow Gift Guide and find something fun for that electronics nerd in your life (and maybe that's you!) www.alpenglowindustries.com/pages/2025-g...

It's alive, it's trapped inside, and it likes music. Audio-reactive pattern and #Pixelblaze by @bhencke.bsky.social driving an 8x8x8 volumetric RGB LED cube with frosted acrylic enclosure. Get your own: lectronz.com/products/led...

I was able to run the PixelBlaze Panama Hat with 150 LEDs for over 5 hrs, looking great at 20% brightness, using this small battery that fit under the hat & at 2.2oz, wasn't noticeable: a.co/d/bbhObkk youtube.com/shorts/TZBFV...

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...

Behold: the 18650 Battery Bandolier!!!! I have limited PwrTop 18s left and will be offering them with a battery at Maker Faire on a donation basis.

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

Production today starts with a dip in conformal coat to insulate the exposed wires and pads. #glowies #alpenglowies #ledjewelry

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

Awesome new support board for Pixelblaze for making amazing wearables, or all kinds of projects really, with pebble strings.

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'm putting a tariff on the word "tariff"! Hooked up an arcade dispenser to give me a ticket every time that god-forsaken word shows up on my computer screen. 20 tickets == 1 beer

I got these boards in just under the tariff wire, and I’m pretty stoked on them, coming soon to the shop! They’re optimized for soldering right to the back of a Pixelblaze Pico by @bhencke.bsky.social, but they can interface with any controller & are an easy way to power everything via USB-C.

I currently have one Fibonacci512 PixelBlaze available for sale, DM me if interested. Please note this one uses WS2812 LEDs, not SK9822. It's still gorgeous (if I do say so myself). 😁 Fully assembled, includes #PixelBlaze by @bhencke.bsky.social More info: www.evilgeniuslabs.org/fibonacci512...

Sneak peek at Pixelblaze Buddy Boards! These interface with a Pico and provide direct soldering for pebble strands, and support any strip via a connector or wires. Convenient USB-C breakout for power. Wired to a 4-pin pebble strand with backup data, then a 3-pin tape strip. @bhencke.bsky.social

PCB assembly and packing process.

I make a super fast simple sound synthesis engine. Designed for microcontrollers, it uses little RAM and flash. Intended for 32-bit microcontrollers that have a fast multiply, like ARM Cortex-M0. github.com/simap/MicroM...

520k and counting! Thank you all for watching this and contributing to this wild ride. Hopefully we can turn this moderate success into something helpful to the world. youtu.be/FEl_S3zHxh4

One of the few benefits of owning my #lasercutter is that I know exactly who to blame for its current condition.

Hey soldering kit makers! Struggling with new coin cell regulations and have a pile of PCBs with coin cell battery holder patterns on them? I made a thing for ours that converts them to USB power, maybe it's handy for you. 🧵

Really nice Mandelbrot viewer. Can even make videos! mandelbrot.page

So 4 pin common anode/cathode RGB LEDs can be charlieplexed! I made a tool that helps figure out how many given a number of GPIO, then added PWM on a subset of them, and refresh rates for charlieplex scanning. Shows a table for PWMable configurations. www.bhencke.com/charlieplex-...

Finished this art piece for my office! The base for this piece is a cork board. I painted the frame, covered the cork in fabric, added a string of WS2812 LEDs controlled by a Pixelblaze V3 Standard LED controller, and then finished it up with some mirrors and flowers. #leds #pixelblaze #wallart

It's that time of year where I spin up the flywheel of effort that runs There U Glow, a femme & queer created, run and centered LED-focused electronics camp. ⚙️ 🦾 Honestly, it's a balm and incredibly vital vibe in these horrifying techbro times. Stay tuned if you are interested! thereuglow.club

If you order a Lux Lavalier Heart pendant now I can't promise it'll arrive by Valentine's Day, but I will upgrade it to priority shipping & try my best. Powered by #PixelBlaze by @bhencke.bsky.social, a small & mighty Wi-Fi LED controller with live-code patterns! ❤️💚💙 lectronz.com/products/lux...

🤩 the Evil Genius is up to more Lab work!

Cool trick for approximating distance fast

My hand drawn circuit talk i'll talk a little bit about anwaar which will cover some of my use of Hybrid caps! @californiasteam.bsky.social has done wonderful jewelry work with hybrid caps and a lot of the tech we use overlap. If you're planning on going to #teardown2025 def consider these talks!

I will be speaking @crowdsupply.bsky.social #Teardown2025 together with these wonderful friends working on similar projects.

Guess what? My talk about the woes of batteries was accepted for @crowdsupply.bsky.social #Teardown2025! I'm really excited and so looking forward to that magical event. Here's a link to my talk last year on using 3D printed parts in production. www.youtube.com/watch?v=4bTh...

Hello! I'm a maker, LED enthusiast, electronic artist, software developer, 3D printer, laser cutter, and hardware tinkerer. I sell and share what I make as Evil Genius Labs: evilgeniuslabs.org If you like anything you see here, it might be available in my store: lectronz.com/stores/evilgeniuslabs

Back at at supercon '22, @zachfredin.bsky.social and I get things working moments before the badge hacking contest deadline. We made an optical “punchcard” reader to load programs into the 4-bit computer badge using scavenged LEDs as sensors.

"Building an expression engine thing that is looking more and more like a compiler and tiny vm." - Me, Jan 2017

Clear TPU is pretty neat, but had to dry it for a week at 60C to get here.

For the #makergiftexchange last week with friends, I made a POV clock. Using one RGB LED and a seven segment display, it draws up to 21 characters and a full circle of 180 virtual pixels on a spinning circular PCB. Loosely inspired by Bob Blick's "Propeller Clock." 🧵1/3

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.

happy “I’m gonna start a side project” holidays

Happy nondenominational decorative tree season!

Finally finished this sign for our friends at Two Broads Ciderworks! Keeping with National Fuck with Pixelblazes Week, this is powered by @bhencke.bsky.social ‘s Pixelblaze. It uses fiberboard with a cherry veneer, sparkly acrylic, and addressable LEDs for backlighting.

It’s National Fuck Around with Pixelblazes Week, right? Hooked one up to a 12V strand we just got with a little buck converter giving the Pixelblaze 5V. Rainbow fonts was the winning pattern for most LEDs on in a rainbow at once. @bhencke.bsky.social

Hey, I recognize that pattern from #PixelBlaze by @bhencke.bsky.social!
