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

@atomic14.bsky.social hey Chris, just wanted to say thanks for all your content, and in particular your ESP32-Tv series which served as the basis for my Tinytron project: t0mg.github.io/tinytron/ Cheers !

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”…

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...

Started ordering components for my ESP32 Rainbow - we've got a lot of displays coming in the post! open.substack.com/pub/esp32zx/...

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.

000

Chris Greening @atomic14.bsky.social · 15/12/2024

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.

Chris Greening @atomic14.bsky.social · 15/12/2024

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

Chris Greening @atomic14.bsky.social · 15/12/2024

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

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

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

Chris Greening @atomic14.bsky.social · 05/12/2024

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

Chris Greening @atomic14.bsky.social · 05/12/2024

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

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

Chris Greening @atomic14.bsky.social · 04/12/2024

Yep - it’s a work in progress, and is very targeted at my own ESP Rainbow board, but runs on pretty much anything.

Chris Greening @atomic14.bsky.social · 03/12/2024

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