Ask the kids where mommy keeps her pink flashlight. They probably
don't know what it's for, but they might know where she hides it.

So far I've built three gear warning systems from Electron Hut parts.
Typically, it's a 6-volt pezio buzzer, two microswitches, and a 9-volt
battery and holder. But that's pretty much what everybody does. A
couple random points:

* These days I'd look into replacing the buzzer with a box that plays
a recorded verbal warning, maybe from a pre-recorded .wav file. Or
maybe I'd just get a Yak Bak 2 toy (http://en.wikipedia.org/wiki/
Yak_Bak) and wire Play into the pair of microswitches.

* I always use an independent battery for the gear warning. I don't
want its function dependent on the main battery.

* I mount the system parts so that I can deactivate the gear warning
if it accidently gets stuck on. I can either pull the battery or
disconnect its wire or break one of the switches.

* I either mount the system parts so that I can test its function
during pre-takeoff, or I add a test switch to do so.

* I never run the buzzer longer than necessary to test its function. I
don't want to become inured to it.

Thanks, Bob K.
