The power supply around here is not the most reliable in the world.
Today it has gone off three times (off for ~3 hours so far), and I
suspect that the voltage is down (fluorescent won't fire up, normal
bulbs are flickering). Is there a cheap way of monitoring the quality
of the power supply (keeping a record) ?


TIA
