My latest blog post: I presented at the 2025 Open Hardware Summit
https://mikecoats.com/presented-at-ohs-2025/
Apologies for the break in blogging, but I've spent the past month preparing for, and then giving, my 'VanSpoof and F**dG3ar' talk at the 2025 Open Hardware Summit.
Best argument for #OpenSource Electronic Design Automation (EDA) tool flows yet!
Article: U.S. Restricts EDA Software Sales to China
Curbs on design software escalate tech war and hit western firms.
…
The latest directive, which appears to broaden previous restrictions, requires major EDA firms, including U.S.-based Cadence and Synopsys, and Germany’s Siemens EDA, to seek licenses for all sales to China, subject to a case-by-case review.

Tips til holdbar tech - reparerbar, åben kode og ikke-forlortede dimser
Jeg vil gerne prioritere at købe ting der er holdbare og åben kode også når jeg skal have den slags tech man kan tage og føle på: høretelefoner, højtalere, smartphone, bærbar etc.
Det føles som det rigtige at støtte folk der arbejder på at lave noget teknologi, som kan holde lang tid, er reparerbart, ikke har materialer fra konfliktzoner og slavearbejde i miner. Men jeg må sige de gange jeg har skiftet til åben, reparerbar, ikke-forlortet tech har det også været en enorm frihedsfølelse. Man behøver ikke smide ting ud så snart noget går i stykker. Jeg kan få mere kontrol over de apparater jeg omgiver mig med!
Jeg har researchet lidt og også allerede taget nogle valg. Kan vi bruge den her tråd til at samle tips og eksempler sammen? Jeg vil gerne se alt hvad der findes af den her slags tech.
Hvis det blive et hit, så opdaterer jeg den her post som vi skrider frem.
Smartphones
Computere, bærbare
Høretelefoner, earbuds
Aktive højtalere, Bluetooth-speakere (farvel JBL!)
Musikafspillere (goodbye Spotify!)

Another piece of cool, open source, user repairable #linux #hardware ordered because #accessibility focused guides on user-repairable hardware basically don't exist. I can't wait to evaluate it and make a post series about the experience. Maybe with some videos! I need a Patrion or something if I keep this up, but oh well. It's fun and people seem to enjoy what I have to say. #mnt #linuxHardware #a11y #openSource #foss #openHardware
Long before smartphones became walled gardens, there was OpenMoko. Launched in the early 2000s, it was one of the first truly open source smartphone projects with open hardware, open software, open everything. The Neo1973 and later the FreeRunner aimed to give users full control, down to the bootloader and radio firmware.
The idea was radical for its time. Developers could tinker with the kernel, replace the UI, or even rewrite the modem stack. But poor hardware, high prices, and limited polish meant it never took off commercially. Still, it left a lasting impression on the DIY and privacy-focused communities. OpenMoko was a vision of freedom in your pocket, long before most people realized what they’d given up.

Dear #openscience swarm, does any of you know someone who would be interested to build/adapt an #openhardware course to create a BIP, who would work in one of these uni:
Chalmers Tekniska Högskola AB
Eidgenössische Technische Hochschule Zürich*
Politechnika Gdańska
Norges Teknisk-Naturvitenskapelige Universitet
Politecnico di Milano
Rheinisch-Westfälische Technische Hochschule Aachen*
Universitat Politècnica de València
Politechnika Warszawska
The second Open Source Hardware Conference will take place in Chemnitz in November. Abstracts can still be submitted until 04.06.25.
Oh no, Openbuilds goes out of business 
The CEO Mark Carew invented the V-Slot extrusion in 2013. We use them on the Bear because the V shape offered an easy alignment during the assembly and more flexibility for the printed parts (no support needed).
Everything must go, check them out:

Thank you Openbuilds and the community for those 12 years 
Recently stumbled upon https://mono.si/, an open source 10 Gbit/s router project that is currently being built by https://www.youtube.com/@tomazzaman
Looks very cool! Should make for a good successor to the PC Engines APU series for low-power routers with custom software :)
I have pre-ordered one, please spread the word to help them secure funding and make their project a success!

The Call for Presentations for 2025 is open!!
I am not in need for a computer at the moment but I wanted to support @mntmn and their team a little, so I bought a hooded zipper [0] with a logo. It is cosy and looks nice. You can do the same to support open hardware projects.

Big news: the first Liberux dev-board is here!
After weeks of work, we’ve finally received the assembled PCB and already started booting it up. Our hardware team has spent the last days debugging, testing, and getting the SoC to talk to the PC, and we’re officially entering the bring up phase! 
We just published a full post with all the details, photos and videos:

Evertop is a portable retro PC with an E Ink display and hundreds of hours of battery life
Most modern laptops have battery life measured in hours. Smartphones may run for a day or two, and tablets can sometimes go a bit longer. But the Evertop is a portable computer with an E Ink display and integrated keyboard that promises “hundreds or even thousands of hours” of battery life from a single charge. And when the battery is running low you can use the built-in solar panel to refuel […]

New video! I'm building the Open Source Arcade Stick in the DE-9 version (Commodore, Atari etc) with adjustable auto fire and lit fire buttons.
