A custom chip, one at a time, in 24 hours

What if you could order one custom chip and have it in 24 hours? 🔬

Normally a custom chip means months of waiting and a minimum order in the thousands. Gotham Silicon wants to make it one chip, about $100, in under a day.

How: → A 1 micron CMOS process (roughly where Intel's 486 was in 1989) → Electron-beam lithography that writes the circuit directly, so no mask set → Lab recordings, build tutorials and runsheets shared in the open

1 micron is old tech, and that's the point: it's enough for a huge range of chips, and cheap enough to make just one.

This is the stated goal and it's still in development.

What would you build if a chip cost $100? 👇
