ESP32 Touch Spectrum - Battery and Expansion port test.

It's time to test the rest of the board and make sure it all works... and there's an exciting teaser at the end!

Nice one - a bodge wire is no mistake, it adds character. And to pickup from the last video, it is still pronounced "route" ...

This is an amazing project - good job! I hope you’re able to get it into production soon. Thanks for sharing the progress (and oopsies) along the way.

Fantastic work, looking forward to being able to order one, great teaser :)

That Pi at the end is the basis for Christopher Nolan's new movie, "Inspectrum".

Very cool! Appreciate seeing your progress. Cheers!

Just brilliant, clever project, beautiful board, and many happy memories every time you get into Manic Miner!
Just one question- where do I plug my 85K Microdrive in, I've kept it for 40 years just waiting for this project ;-)

You need canbus onboard. Just me maybe, but I'd bring out all the I/O pins from the ESP32 that aren't being used already.

Will be interesting to see how far you go down the certification route.
looking forward to seeing the D.O.C, remember your need UKAC, CE just for us and our nearest neighbour

Point to note, as the ESP32 has Wi-Fi it's classed as an Intentional radiator, so that means Radio Equipment Directive (RED) compliance is required. a side issue with RED is that is removes the low voltage part of the Low Voltage Directive (LVD). where the LVD states it's only for equipment between 50 and 1000 V for alternating current and 75 and 1500 V for direct current, RED removes the lower voltage limit so it will read "0 and 1000 V for alternating current" and "0 and 1500 V for direct current. So that's two directives and counting.

Now days it's better to supply it as a kit of parts, which might mean that all you might need to meet is the Restriction of Hazardous Substances (RoHS) directive. Maybe with the "Control Of Substances Hazardous to Health" (COSHH)

The fun of placing something on the market as the law calls it. It's last person who places it on the market that gets all the pain if things go wrong. 🙂

I'll keep my eye out for the unpopulated PCB. 🙂

Hello can you modify our code very small code

[megazoid]

It's fleshing out nicely. Worth adding a resettable fuse on the USB VCC line?

Interesting Chris, a few questions though: Are going to use 2 SoC and 2 emulators? Is it Fruit-bat emulator on (expansion) RPI Pico? Which emulator on ESP32?

[lumsdot]

cant you say its ready to buy now, then make us wait 2 months, like clive s did

Would be great if it could have connector for linking to existing computer monitor (eg. HDMI or smth)? The thing I loved most about the speccy was I could take it round a friend's house and connect it to the telly.
