It’s finally happening! Apologies for the delay. International bulk shipping to the US has been a bizarre experience.

It’s been pretty eye opening - the difference between sticking something up on tindie and doing it “properly”…

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...

That's a lot of displays! I've started locking down components - we need to get ready to kick off production!

I’ve got ESD protection on the USB port and the ESP32 module seems to be pretty robust. To be honest, I was expecting it to fail horribly.

Next step will be RED testing - which hopefully should be straightforward as the module is already CE certified - but I wanted to get at least the basic certification done before that.

And I think this is testing to see what interference is getting back into the power supply (though I'm not completely sure).

How long does it take to map the LEDs? And have you tried out his 3D mapping?

The stock keyboard firmware doesn’t support key up/down events - which makes playing games pretty hard.

Keyboard is a bit useless on the T-Deck. But this is running the same software as my ESP32 Rainbow.
