I’ve just updated the VGA clock PCB to take advantage of a batch of new chips.

I think my VGA clock design might be the world’s first certified open source hardware down to the chip level.

Unfortunately the MPW1 chips were very hard to use and the new ones have a different pinout and footprint. I’ve been using the clock design as a test project for all the Tiny Tapeout chips past TT03. To test the new mux structure introduced at TT04, we ran an experimental TT3.5 chip. The chips are back and the clock works as expected (phew!)

As we have a hundred chips but no customers, I’ve decided re-spin the board and finally fulfill my plan to sell a few and donate the proceeds to OSHWA.

The new board’s repo is here: https://github.com/mattvenn/tt-vga-clock-pcb

Until the docs are updated the OSHWA certification refers to the previous version.

If you’re interested to know when the boards go on sale, leave your email on this form.
