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...

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!

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.

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...
