Pretty impressed this worked. Back when I was doing my PhD simply extracting the numbers from an image reliably would have been a good result.

Been messing around with my latest PCB - I've now got a "digital twin". More details at the video: www.youtube.com/watch?v=6vpd...

Nice - though I’m now regretting not shipping with rubber feet!
My ESP-Rainbow created by @atomic14.bsky.social was delivered through @crowdsupply.bsky.social today! I just added some rubber feet, fired Chromium on my Linux laptop and upload Manic Miner 😁
The first impressions are terrific: menu, games loading and keys all worked as they should.

It’s finally happening! Apologies for the delay. International bulk shipping to the US has been a bizarre experience.
@atomic14.bsky.social Hi Chris. Just checking that the ESP32 Rainbows are still on track? I've not heard any shipping messages just yet.

Pretty interesting - I really thought it would be the capacitors that had gone wonky.

Nothing like scratching your own itch. Wanted a nice easy way to convert from ZX Spectrum SCR files to PNGs. There are some nice command line tools for doing it, but here's my web version. www.esp32rainbow.com/tools/scr-to...
