Does someone understand the difference between those NXP parts?
* PTN5150 vs PTN5150A
* PTN36043B vs PTN36043A

Precious Plastic - designers of open source hardware plastic recycling machines need your support! They are a very small team and launched a whole community of REAL recycling communities worldwide who use their DIY machines to recycle plastic waste into useful new objects, keeping the waste out of landfill, but they are having financial difficulties because of a long chain of mishaps and problems. See https://www.preciousplastic.com/news latest post for details #recycling #preciousplastic #opensourcehardware #community

For the second year in a row I designed the electronic badge for the DORS/CLUC conference in Zagreb - one of the oldest open source conferences in Europe. It has some fun features and there were some "fun" challenges while making it. Here's the full writeup: https://hyperglitch.com/articles/dc2025-badge

Have you noticed there are tons of great hardware on kickstarter but they usually don't get mass produced and then we don't have them in the market?

They usually come in very limited quantities...

Wow 17 years already, time flies! Thank you Adrian, for your invention and all your hard work 🙏🎁

Omi is what happens when wearable tech meets AI.
Put it on. Speak. It records — automatically.
No buttons, no hassle. Just seamless memory.

🚜 What if the Unimog had stayed in the commons?
Born post-WWII to serve many, built to last, the Unimog met global demand — and then its creators went bankrupt. Not from failure, but from success.

They sold to Daimler. The rest is planned obsolescence.

What if they had released the IP instead?

@jbqueru Also I hope for #RISCv to be the #ISA of the future for long-term #OpenSourceHardware and support.

#ARM64 - just like #amd64 - is yet another proprietary ISA and almost all devices with it in terms of #Laptops have #AntiRepairDesign like #Apple's #MacBook|s that self-destroy their #SSD|s which also contains it's #EFI / "#BridgeOS", making machines with fried SSDs 'braindead'…

And yes, #RAM to also fails and making it not fully replaceable and upgradeable is inherently bad and I'm still mad at @frameworkcomputer for their botched #FrameworkDesktop #PC!

• Cuz it's neither necessary nor beneficial for a #Desktop PC, unlike with the #Framework12 where the #SoC used only supports single channel and a single SODIMM so it makes sense for them to take that into account.

Also #esphome ist schon was cooles. Hab mir so n Entwicklerboard von #funduino gekauft. Als Lötübung. gabz lustig. Gibt nen Adapter für #esp32 dafür. Alles schon beschriftet. Noch nen CO2 Sensor dran gehängt und dann über #esphome in meinen #homeassistant integriert. Flutscht einwandfrei, Daten auch direkt im #grafana sichtbar. Mini-Wetterstation mit Knöpfen und LEDs und Display zum Anzeigen von irgendwas.
Temperatur, Helligkeit, Luftfeuchte, CO2. Fehlt nur noch ein Luftdrucksensor aber den habe ich gerade ausgeliehen.
Jetzt nur noch überlegen was ich damit alles anstelle.

Das Entwicklerboard ist übrigens #opensource #opensourcehardware vom #hackerspacebremen e.v.
Super zum Lernen von arduino ohne dass man sich groß mit Verkabelung auseinandersetzen muss.

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 🙏❤️

@hofmannedv da Software auch bei Hardware mit im Spiel ist oft, gibt es selten nur "eine" Lizenz. Dennoch sind die beiden genannten die bekanntesten. #OSH Lizenzen, oft wird noch CCBYSA verwendet, historisch gewachsen. Wirklich zeitgemäß sind aber nur die 3 CERN OHL Varianten (ggf. in Kombination/verschachtelt mit anderen Komponenten im Nesting als "Available Components")

Wir geben dazu auch ein paar Hinweise in unserer #OpenSourceHardware Broschüre, hier als Auszug:
