Mats continues his challenge of designing one PCB every week. In week 7 he designed a voltage and frequency logger for household mains power supply. The device is designed around the ATtiny45 microcontroller which records the frequency and voltage, and passes measurements through an onto-coupler to an isolated logging board....
