Oh good. The order of a spool of atmega 4809 microcontroller I ordered during the pandemic just shipped.

1000% forgot I ordered them

If anyone has a suggestion for what I can do with 2,500 8 bit microcontrollers I'm all ears

@Firr

What package are they?

@Firr What were those originally for?

@Firr 2500 of them?? Heck, you could make a TIS-100 mesh computer and not even scratch the surface. At that scale, drivers for eink badges that you could resell? distributed mesh lighting controls? Very impractical business cards?

Perhaps up your alley, but it's not going to use enough of them, maybe animatronics?

There's also the whole space of IOT-style widgets, but needing physical wires or additional HW for interconnecting things would be a drag. In the end you might need to embrace having a lifetime supply of 8bits or a double lifetime supply of 4bit nibbles.

@Firr very small ziggurat
@Firr Build a Beowulf cluster.
@Firr 3 LEDs (green, yellow, red, like a traffic light) perched on the top of a computer monitor (like a webcam, and a button to light them up alternatingly. This warns others around that one is in a Zoom or Teams call. Red means do not disturb (to one's family or roommates). Yellow means will be available soon. Green means available. It's silent signalling to one's household members without the meeting participants noticing.
@Firr Make one 20,000 bit macro controller.
