I mildy fucked up my cheapo machinist block but its perfectly right angle and flat, which is rare when I weld square stock together. Overall feels like distortion happens a lot less with the laser

Whats with embedded devs and coming up with weird new ways to calculate a checksum.
Today I found through trial and error the checksum for a UART message protocol:

checksum = (0x08 - byte[5]) & 0xFF

Did they just roll a dice on this or smth

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.
