I also am building Phaestus, a 0 to product system, that builds entire products from scratch.
https://www.mikeayles.com/#phaestus-wip
It is capable of creating a PCB (and outputs gerbers, bom, pick and place files), an enclosure (written in SCAD, outputs an STL for printing), and firmware, which it's able to compile using a pio runner on railway and provides a binary, but also has a webserial flasher for ESP32's.
There is a blog here, but i've been focussing on getting things finished, as I built it for a hackathon ending today.
I need to update the blog & writeup, because I have the first product it created, a bluetooth remote control. It wasn't without issues, but I have a working PCB, in an enclosure that was printed from it's design, running firmware it generated.
What was the hackaton?
