Fuckin' world record in a cheap sonic costume that looks like the most uncomfortable thing ever.

Trying to watch the Nier: Automato run and wishing they'd turn down the game audio.

WELL WHAT ABOUT THAT

That Pumpkin Jack run was amazing.

What if humans were never meant to sleep lying down? What if we were meant to sleep sitting and leaning against a werewolf? Never thought of that, did you?

On the plus side, I'm hoping to get this sent off to the fab by the end of the month. We'll see if it happens or not, but I've gotten past most of the roadblocks in making this so, fingers crossed!

Thinking about putting a hash of the source file on the board. Absolutely no way to verify that's actually what was used, but in non-bad-actor cases it'd let you be sure which version you sent out.

A shame there's no standard for the fab-house auto-inserting it so the hash would actually verify without having to make a different copy of the file with the hash on it just for manufacturing.

Basically I'll have parallel SPI connections for the GPIO header + controller, maybe put some of the GPIO of the port controller onto the header, too. Will see, have to fuck around. PD 75W+ may be done through the header too. All stuff to figure out as I work on it.

Did a bunch of other posts on Twitter I forgot to crosspost, but that's okay because: NEW PLAN! (Re)discovered the UPD350B aaaaaand yep, it uses SPI, does PD 3.0 comms, has GPIO, it's pretty much fantastic as far as USB-C port controllers go. (Which, you know, could be better, could be worse.)

So, like, I dunno.
1x CAN bus
1x DRP USB-C with Power Delivery + Accessory support
vs.
1x CAN bus
1x DRP USB-C only
1x GPIO/SPI Expansion Header w/Clock source
vs.
2x CAN bus
1x UFP USB-C
1x GPIO/SPI etc

But another big choice is I've realized I could probably power the system via the USB port, too, using the 20V/5A standard. PCIe connectors are (kinda) rated to 75W which would be enough. For that I'd have to use *both* the CAN/I²C *and* the expansion header GPIO lines.

Currently there's an 8 pin connector that has two CAN buses plus power and ground. But I'm probably gonna have to drop one if I want the USB port to have dual-role functionality since it shares pins with the I²C bus I'd need for the USB controller chip.

Alternatively I could maybe use a microcontroller as a protocol converter but then the backpack expansion header would have to go away. That'd free up some space but I'm not sure it'd all still fit since it's not an integrated solution.
