This is a very neat solution, thanks for sharing!

With triple-AAA holders, a wire-connector pin was included, to be inserted into the relevant spring... which might not be too handy when replacing batteries. But I guess I haven't posted any picture of that modification - your one is much better.

Indeed, trying to solder anything on the holder results in immediate disaster

Sure, will get back to that part once all is shipped - would not be fair to delay it, mainly because some backers got it weeks ago while others are still waiting (could go forever, you know, that's how the software is...    )

The sensor is safe to use with strong magnets, it would need to be a really strong one (or rather an AC field) to damage something - and it would probably damage rest of the electronics as well

Stronger magnet will make it possible to control from larger distance, and therefore more precisely.

But the rings work well enough - I tried this one with inscriptions and this one with darker band, they are good, this hematite one is a lot weaker and almost unusable. Haven't tried this one, looks the same as the darker but might be made from different alloy.

UPDATE: The silver and gold ring arrived and work well - they're much stronger than dark one.

Yes from the channels in current beta firmware, only one or two respond to it. The programming channels are broken (sorry, it happened while last-minute refactoring and optimizing other parts of the code, and I've noticed it only after flashing over a hundred boards).

Hi Guys,

If you are interested in hardware extensions, look here: http://www.gechologic.com/diy-kits-guide

It explains MIDI, in case you want to add it using commonly available elements.

Also, the last picture shows all soldering pads. For more information, you might want to check out the STM32F405RGT6 datasheet: en.DM00037051.pdf

Any questions welcome! 

Hi Gaël, welcome on board!

Thank you, I'm delighted to hear you like the PCB, sound, and especially that you find settings intuitive enough. There is still work left on it, but I'll keep it within what the "Quick start" sticker says.

Yes, the code and everything will be published very soon. I am trying to balance work between shipping and catching up with what was promised at the software side (also to get a break from manual work once in a while )

Do you mean "no delay" as if it should start playing immediately, a default channel, without needing to press everything? Or, no delay as having echo completely off? (that can be currently achieved by pressing button #3 during play, more times - till it reaches that setting).

Midi sync and chords from keyboard will be definitely achievable, glad you are interested in expanding the firmware!
