Nice to see YouTube showing adds that deliberately try and mislead users.

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!

Taki@oldtaki.bsky.social

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.

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...

My poor boards got zapped... and they survived! We passed EMC and EMI tests ⚡

15 Dec 2024

Here's the setup to see what my board is radiating along with the test setup.

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

Well, this is fine…

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

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

We’ll soon have websites run by hipsters. Hand crafted HTML - or maybe… frontpage!

Michael Antczak@mantcz.com

There will be only two types of websites soon: 1. AgentWeb - Build, run and optimised by automated agent at some web farm 2. ArtisanWeb - handcrafted by a human 😀

3 Dec 2024

It works - but unfortunately without reprogramming the keyboard controller it’s pretty useless.

But it has made me thing the next project should be a hand held spectrum emulator…

1 Dec 2024

I’ve got to include this on my next board run.

We did it!

Video about loading games into a ZXSpectrum from tape - CTR 4.6%. Video about fixing a broken nose hair trimmer - CTR 8.2% I know what my audience wants :)

youtu.beOld School Tape Loading - Can we get it to work?YouTube video by atomic14

Took a nostalgic trip back in time to play with some tape loading. The sounds really do bring back happy childhood memories (and the memories of "R Tape loading error"...) youtu.be/sTRcuNMziwQ

On the ZX Spectrum a 0 bit was represented by a high and low lasting 1710 T-states (around 488us in total) and a 1 bit was represented by a high and low lasting 3420 T-states (around 977us) - so depending on the content of the file the loading time could vary dramatically.
