Hi Paul,

Your driver PCB is looking good!

Do you have any specs on those driver transformers you are using (turn ratio, inductance, isolation voltage)?

Also instead of using the ATTiny, why did you not just use an off the shelf Half Bridge Driver for a 50% duty-cycle? Example: (IR2085S).

Keep up the good work
