Hi, I would like to help you on this project of yours. It is similar to one I had to for a medical device to treat skin for newborns. The easier/cheap way to detect if your UV light is not working is to detect how much current is being consumed on the secondary. With a low impedance resistor you should have a small voltage drop. If there is no drop is because the bulb is burned out. A 1USD solution is to use a reed switch. The biggest advantage is to be electrically isolated from the secondary voltage. More expensively 2USD, you can have a optocoupler. The timer is done with a simple RC circuit, to drive a comparator with hysteresis to avoid rapid switching. The alarm can be either audible and/or with light. The volume, brightness (view radius) can be tweaked to met the placement of the board. All the best, Filipe
