The 2026 Open Hardware Summit is coming.... to Berlin, Germany! On May 22nd and 23rd!! Still so much news to come here but we wanted to be sure you knew! For now you can enjoy the beautiful logo designed by @bleeptrack@vis.social and check out the site at 2026.oshwa.org

(livestream heard it first🤭)

Yep! It's from a Chinese clone

was wondering how you would print that, mystery solved :)

Second to last dimensions check for the #WHY #Badge Cover. Fusion file and STL will be made available soon, a slightly earlier version is available at gitlab.com/Dynom/hardwa...

Also checkout the model of @davedarko.bsky.social at www.printables.com/model/136919...

Only 7 days until #why2025!

So I've published my model now as well. I'm a perfectionist .., however 3D printers need time to print and people need time to pack, so here goes: www.printables.com/model/137231...

Please read the information, but I think it's come out pretty well.

The Omnifixo plate with a 3d printed case above. The case contains a Type-C to DC Jack adapter, the TS100 soldering iron, and the Omnifixo clamps. There are also two magnets that hold the Omnifixo plate on top, forming a case.

Like many recently, I have joined the Omnifixo owner's club. Together with this case from @commar.bsky.social, it's the perfect all-in-one travel solution!

Berlin Swapfest @ c-base The Berlin Swapfest is a place for people to buy, sell, and swap electronics, computer equipment, and tools.

After the success of the first Berlin Swapfest we're happy to announce the date for the next:

July 20th, 2025 at @c-base.org from 12:00 - 18:00

We're incredibly thankful to everyone who attended the last and we're excited for the next!

New LED polyhedron build is underway. It's a dihedral hexacontahedron with 60 kite-shaped sides. My PCB polyhedron builds are getting better. These 3D printed tile covers use a translucent PETG designed for lithophanes plus a larger air gap than the last build for much smoother diffusion.

Well I guess you have your solution then :)

what's your hourly rate to design boards and ship them? :)

My ESP32 Rainbow board being zapped!

My poor boards got zapped... and they survived! We passed EMC and EMI tests ⚡

The Party Pet digital prototype, which is a Tamagotchi-like screen hooked onto a cup on the left with the Arduino and all of the wires.

Say hello to the Party Pet, a digital companion to help you meet new friends and have deeper conversations!

Created for our final project in our Theory of Tangible User Interface class at UC Berkeley.

Made with Arduino :)

Gah I love 1812, this way even more.

New episode of @thebootloader.net is out! @paulcutler.org & I chat about Hackaday Supercon 2024, SAO badge add-ons, some of our favorite talks. I made part of the official badge! www.thebootloader.net/blog/2024/12... or where you get podcasts.

Got a case designed and printed for my open source #spotify car thing powered by the #ESP32. The knob on the side controls volume and the buttons on top do playback! Now I just need to figure out how to decorate it! I'd love to hear any ideas if you have them!! #arduino #electronics #music

I have several potato cameras

that too

I have about 25% of that and my main theory is that we're shown during the onboarding process that's supposed to help people see some content on their feed. Sadly hackadayio feels a bit dead when it's not running a contest.

I've treated myself to a Raspberry Pi Pico advent calendar this year. Day 1 was basic setup, but today I made an LED blink. Witness my power!

Working on my open source car thing alternative since #spotify is shutting them down in a week 😞 it's running on a #ESP32. everything is working and I can play, pause, skip songs, etc. just need to make a case and it will be ready to go. Video on my YouTube with the whole process soon!!

Assembling magnetic mounts for LED panels. Each mount is about 10 cm wide by 3 cm high, and has six magnets anchored to them in a 3 by 2 arrangement. The magnets have M4 threads on them anchored by locking hex nuts. At the upper left is the remnant from an earlier attempt of threading the magnets directly into the holders. Trying to tap the threads accurately proved to be problematic.

Working on a large LED scoreboard. These are magnetic mounts for the panels that fit into T-slot extruded aluminum rails.

neat! :)

3 hexagon flowers

more is always better. now where did I put the other hexagon pcbs?

not a smol project at all, if its not in Hamburg anyways, then yes, you should book soon

a shot of the circuit graver at the Supercon8 soldering table in the alley behind LACM. when not giving or attending talks, I spent a good deal of time carving PCBs for attendees, it was great fun!

7 PCBs arranged in a 3d printed frame, a pink esp32c board on top

7 hexagons with six LEDs, a rainbow animation over all LEDs shining through the 3d print

Finally doing something with the populated LED hexagons I've ordered almost two years ago. 3D printed a frame to hold the PCBs and also as a dark diffusor.

sounds cool, but what does it sign then? :)

that's some witchcraft RF stuff :) or maybe not - great project!
