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

MAX30102 + ESP32-C3 OLED - a perfect match!

We're going to have to do some surgery on this to turn the volume down!

This brings back some happy memories :) Original audio and analysis here: www.windytan.com/2012/11/the-...

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.

Been messing around with my latest PCB - I've now got a "digital twin". More details at the video: www.youtube.com/watch?v=6vpd...

This is some serious packing - a box within a box within a box. The displays have arrived safely!

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...

Nice bit of bathroom electrics :)

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

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 ⚡

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

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

Pretty pleased with my new cable management - though I need more now!

Sometimes have to lunch myself when I look out the window.

Even closer! I'm going to stop posting updates on this until it's funded - otherwise it's going to get a bit boring for everyone :)

Chris Greening @atomic14.bsky.social · 20/11/2024

Getting very close to fully funded! www.crowdsupply.com/cmg-research...

They appear to have stopped responding to me... I believe I have won this particular internet battle :)

I try not to let comments like this annoy me, but you do see them an awful lot. news.ycombinator.com/item?id=4218...

Got sound working :) Pretty pleased with this - pretty much the same code that's running on my ESP32 runs on the desktop and in the browser.

Chris Greening @atomic14.bsky.social · 18/11/2024

My first try at using emscripten - compiling my ESP32 ZX Spectrum emulator to run in the browser. I can't believe how simple this was!

What did you use to diffuse the LEDs? I’ve made similar things, but have always struggled to hide the individual pixels.

Really starting to lose faith in Azure - how does a Zone Redundant app service randomly just go unavailable?

Fingers crossed, should hit the funding target easily. Big thanks to everyone who has backed it so far.
