Most of the SPAM mail I receive dropped to zero when the #Iran war started (and anytime the US has had a conflict with someone). Today it all shot back up on many accounts I manage. It makes me hopeful that an agreement has been reached.

Yay! The main #PCB for my MOS #KIM-1 replica arrived today from #JLCPCB! The sub-boards seem to fit. Bringup will take awhile since there's a gross chip-pin-numbering error on one of the smaller boards and I'll have to re-fab it. But I'll be able to partially assemble it and test a few things.

When your latest #PCB uses a #PCI connector (super dirt cheap) and you want the customer to know that they should not even be tempted to plug it into a PC. I used the connector but the pinout and voltages are nowhere near those of PC Cards. At least the warning will be entertaining. #KiCAD

A Printed Circuit Board with what looks like a PCI connector edge. There is a warning imprinted onto the board that states, "Absolutely NOT PCI! Do NOT attempt to use in a computer. SMOKE, FIRE or SMELLS MAY OCCUR."

Tracking the person delivering my #UPS package. This individual should get a job in professional gerrymandering. Has driven past my neighborhood twice already and returned to multiple places they were before. Package is also an hour after the original delivery window. This is performance art.
