I've been playing around with ESP32 MCUs and displays for a while and finally got around to getting a ZX Spectrum emulator working. I then saw that you can now do full color silk screen printing on PCBs and got the thinking - the ESP32 has capacitive touch capabilities - I could make a full ZX Spectrum keyboard on a PCB along with all the electronics for running the emulator. And it actually works!There's a full video here: https://youtu.be/foP81O48WAI
And you can sign up here for updates as I move towards getting it ready for a production run: https://esp32zx.substack.com/p/announcing-the-esp32-zx-spect...
It's looks amazing, takes me back to my childhood.
