Thanks for those of you who sent me the $2 for the ceramic insulators. In your note please include your DIYA member name. I have a hard time connecting your email address with this list. If you have paid the $2, please edit the list and indicate so next to your order.
Thanks,

Waiting for boards😀

We have to verify that it works before I release as a general GB. We have 3 beta testers including me. Four beta testers if JPS64 goes at it too.

Hi X,

I need! Firmware to do! Coming from aeronautical development, safety most important!

So the fan PWM daughterboards need to be connected to a micro controller?

I saw $4 PWM fan controllers with alarms and set points on Ali that I may get just to play with. I also have mechanical 75C temperature limit cutoff switches.

Your smart amp controller sounds like the best way to have everything controlled and safe.

They are a bit more expensive on Amazon but available right away to let me run the fans.

Excellent work with nice micro details, a lot of attention went into these PC boards.
All do I will almost sure I do not build this version still I want to thank you for your effort in the DIY community.
