Looking at dmesg, and the USB stack is literally dying, causing one of my cores to livelock, which eventually forces me to hard reboot, since it kills my mouse and keyboard.

That said, I can at least confirm that my rev 4A of my PCB works!!

Life is hard.

Here's Tabitha sleeping on my belly, hugging me in her own feline way.

I know it's not Saturday yet, but who cares. You must enjoy these moments as they happen, not when you want them to.

Before and after. Will it work? Don't know; but it is electrically identical (as far as continuity tests go) to the original.

I'll find out later this week.

Remember that jumper that I needed to install? See if you can find it.

(30 Gauge wire from pin 1 of U2 to its decoupling capacitor.)

There. A freshly minted, new old stock 14 pin DIP socket.

Still more hackery. Since I don't have any available 14 pin dip sockets, I've decided to convert one of my 24 pin wide sockets to several sip sockets. This should be sufficient for my needs. I promise to use real sockets when I come out with the actual kit. ☺

Turning a spare 40-pin DIP socket from the 70s to a 28 pin socket to fit the TinyFPGA BX module.

DIP switch now soldered to the PCB. Let noone tell you that DIP packages can't qualify as surface-mount devices. ;}

Splaying the dip switch pins out and placing them Just right so that they make good surface mount contact. Next up just got solder them.
