Adding a battery? · atomic14 esp32-zxspectrum · Discussion #26 What's the name of the connector for the battery on this board, and what batteries would you recommend for usage with this board? What's the best run time we can get with a battery hooked up? Anyon...

I’ll add some more details here: github.com/atomic14/esp...

Pretty easy - it’s already got the battery charging circuit.

For some reason I find this the most stressful time - what mistakes will discover when the boards arrive…

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.

Nice - though I’m now regretting not shipping with rubber feet!

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...

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).
