Great design! I have two things that I would like to ask:

1: How about a safety interlock that only allows it to operate when the lid is closed? That rotor seems to be going a good RPM and could hurt someone I imagine if they got too close. This could just be a NO switch on the power supply for simplicity.

2: How about substituting a simple tiny45 with a basic program reading a pot then using PWM to control a MOSFET into a lower cost motor perhaps? This could lower overall cost, is there a minimum RPM that must be reached for this to operate properly?
