Thank you for the variac explanation Mike, I do have a variac here (the transformer variety) but was not sure what you meant with that word in regard to the control card.
Now, I do like to copy your ideas (I hope you don't mind) and when I saw your interesting use of a 'current type voltage transformer' for sensing the AC mains voltage I thought I'll have to try this.
So I laid out a control PCB with this instead of the original LT1638 that Poida used.
But I'm curious if this will work with the original Nano program?
I'm using your early version of the MC74AC86 gate drive BTW.
I'm not interested in many of the features your latest control card offers (have external fan temperature controllers and no need for automatic start up or a status display monitor.
I finished the PCB layout but have not sent it for manufacturing yet until I know if my original Nano works with your AC sensing or if I require a different program.
Thanks
