We've had some pretty dang cool badges over the years of the Open Hardware Summit existing! From PCBs to e-textiles to lego we've explored lots of ways to play with #badgelife and this year will be no different.
While it's still in production for #OHS2026 you can think SAO header, & your random extras: the LEDs you've had sitting, the weird button you haven't found a home for, IC's you ordered too much of & let's prevent some e-waste with badge hacking!

uuuh, I think that is not a USB device...

I guess this is just straight up UART, goes to a ESP32 without any IC inbetween

Seeing this EV conversion is making my neck hair stand up.
Rebuilding a high voltage car battery willy nilly in some completely different configuration while clearly not knowing what the fuck he's doing 😬😬

At some point a car guy like that is gonna electrocute himself

And another reason why Python packaging needs to gets fixed upstream. You can't have the languages package management be treated as a thing to be implemented by third parties.
Please CPython, finally learn from node and Rust on how to do this properly.

Sometimes I think James Cameron mostly makes movies to fund interesting science.
Avatar: Fire and Ash is not a movie I have any big desire to watch but the technology Weta developed for this is absolutely incredible. Huge step forward for generalized fluid simulations.

so uh
we rescued a set of 4K movie film scanners

does anyone need a set of 4K movie film scanners

if you have a need for a cinema film scanner (or can give it a good home!), and can arrange to have it transported from the Seattle area, message me on fedi or e-mail me at [email protected]

Also one of the few high end BLE parts that are still coming in QFN (normal QFN, not the weird QFN from nRF52 times).
While most wearable want WCLSP, for more normal stuff QFN is great to have as cheaper to implement option if you don't want to go with a module.

If you know the nRF54L15 already, its all of that + High Speed USB, 2MB RRAM (NVM), 512K SRAM.

If not:128 Mhz ARM M33, a 128MHz RISC-V co-processor that can do software defined peripherals (written in (C) code) and the usual excellent BLE and other 2.4GHz radio stuff while being extremely low power.
Price wise also fairly cheap at 2.5€ in singles (much less in high qty).

Even if you ignore the wireless this is a neat part.
