PicoIDE is an open source device that lets you use a microSD card reader with old-school computers instead of an IDE hard drive, CD-ROM, or floppy disk drive. There's also a Deluxe model with an OLED display and WiFi support. Crowdfunding now for $69 - $110. https://www.cnx-software.com/2026/02/02/picoide-an-open-source-hardware-ide-atapi-drive-emulator-for-vintage-computers/ #PicoIDE #OpenHardware #Crowdfunding

Finally, a 3D-printable exercise machine that turns your efforts into electricity for a phone or battery bank. Designed to be backpack-portable, too, so you can get a sweat on anywhere you like!

If ever you need to buy USB wifi adapters for linux this repo has it covered:
https://github.com/morrownr/USB-WiFi
> The mission of this site is to provide educational information, reviews of USB WiFi adapters and links to specific adapters that are known to perform well with Linux ( see The Plug and Play List ).
It's updated often.
I did try FSFs 'Respects Your Freedom' site too but choices are limited(understandably) and US focussed:

I'd really love to see an #OpenHardware, #OpenSoftware matrix mixer & DSP processor.
Likewise for modern PA systems, in order for them to be any use, you must rely on a proprietary matrix mixer and DSP processor to process and route the signals from the mixers to the loudspeakers.
While I think this is largely "fine", it would be great to have something for smaller venues and operators who are running older and maybe cobbled together systems. Ditto for up-and-coming speaker system designers.
I would love to work on a start-up to develop a #Linux and #OpenHardware based audio platform for developing #MixingConsoles, #DSPs, #AudioDistribution and more.
I wonder if anyone is working on such a thing?
Zerowriter Ink is now shipping: An open source E Ink word processor with a mechanical keyboard
The Zerowriter Ink is a portable word processor with a mechanical keyboard, a 5.2 inch, 1280 x 720 pixel E Ink display, an ESP32 microcontroller, support for WiFi and Bluetooth, and a 5,000 mAh battery. It runs open source software designed to offer a distraction-free writing experience.
Zerowriter Ink developer Adam Wilk launched a crowdfunding campaign for the device in 2024, and now Wilk […]

Random musing of the day: What would it take to build an open source atomic clock?
Designing an atomic clock and making the design open is easy. Heck, there are plenty of schematics and drawings of commercial clocks online. But making it such that Joe and Jane Average could replicate it at home without any parts or devices that are hard to get or extremely expensive? That's a tough nut.
The Serial Wombat 8B ecosystem - cheap WCH RISC-V microcontrollers loaded with an open-source firmware and installed on boards that act as smart dev-board expanders over I2C - grows four boards larger now, as Jonathan Broadwell launches a new #crowdfunding campaign.

#Hamradio Manifesto : from usage to creativity
A short writing to define a strategic transition: moving from passive use to the design of resilient and innovative communication systems:
* an open & modular RF stack
* Mesh Networks and Technological Resilience
* RF Hacking and STEM Education

Standing room only in a full #fosdem #openhardware #CAD #CAM room for Yoriks "state of #FreeCAD" presentation. #opensource
Morning from #fosdem #openhardware #CAD #CAM devroom, we are underway with a great range of talks across the day. Ask this idiot in a cool tee for any help you need.
My latest blog post: Using a Spy! Break! Inject! to Sniff I2C Traffic
https://mikecoats.com/spy-break-inject-sniff-i2c/
I've been exchanging emails, discussing debugging protocols like I2C with my Spy! Break! Inject! and I thought that writing this up as a blog post might be useful to others.
Super long #fosdem2026 day. Excellent conversations had on the @FreeCAD and @kicad booth. Food and sleep now before co-managing the #openhardware #cad #cam room tomorrow!
The new UNBRK HEX boards have arrived! An improved version of the UNBRK, this ultra-compact prototyping board for QFP48/64/100/144 MCUs has wider trace geometry for better low-power performance, provisions for header pins, and an improved, unique 0201 prototyping grid to experiment with components reclaimed from #ewaste. #openhardware released under the CERN-OHL-S and supported by @nlnet and @NGIZero, you can find its repository at https://repo.unbina.re/unbinare/UNBRK_HEX #fosdem2026
Flipper Zero Wi-Fi Boards Explained (2026)
Adding a Wi-Fi board to Flipper Zero opens up a lot of possibilities — but not every board fits every use case.
This guide breaks down ESP32, ESP8266, and ESP32-S3, with practical notes on:
• strengths & limitations
• compatibility details
• which board makes sense depending on what you’re trying to learn or build
Straightforward, no hype.
