Step 6Improvements
A couple things could be improved:
1.Put the screw terminal closer to FET for better ground path.
2.Fatten the supply trace to the capacitors and inductor.
3.Add a stable voltage reference to improve operation from batteries and supply voltages less than 7 volts (where the output of the 7805 dips below 5 volts).
4.Use the upper 55 EEPROM bytes to log fascinating bit of useless data - total run time, overload events, min/max/average load.
