I just rigged up a standard boxing glove on one of those spring loaded accordion arms to punch me when the oil pressure gets low. It's like a left cross. Works good, no buzzing until afterwards.
BTW, my neighbor's name is Piezo and his lovely wife Patina.
Their kids are Holley and Zenith.
The dogs name is Babbitt. Nice family.
Instead of a buzzer, why not just have a cd play Bowie's "Ground Control to Major Tom, Your circuit's dead, there's something wrong"
