Hello there, this is just a very quick update on the state of the project since I haven't reached out to you in quite a long time. I've investigated some issues with the temperature dependency of the threshold and the gain. It's not a big issue, but it can be annoying if you use the board in an environment where the temperature can change over a much wider range than indoors. You can always increase the threshold a little bit above the needed voltage to have a small safety margin, so it won't affect you nearly as much.

These problems will be fixed with a slight change in parts and more optimized circuitry. I'm going to do one final updated revision of the board with these changes and maybe some other slight improvements that come to my mind. I'll update you once the work is done and the hardware is ready, so stay tuned!

On another note, the Mini SiD is sold out on Tindie, so thank you all for your interest in this project and the support. You can still get some of the Tiny MicroFC breakout boards if you want, the sale is still on until the end of september.

Cheers!
