7. Mains Failure Alarm (1994)

​

Hardware: Microchip PIC microcontroller

Software: Microchip PIC MASM macro assembly language

​

The housing estate where I live was still relatively new and suffered the occasional mains power failure. It occurred to me there could be other places suffering longer outages that might disrupt electrical systems, and I set about designing and building my 'Sentinel' mains failure alarm.
