For remotely turning on and off your heli simulator computer of course...
Me and my dad came up with this circuit for making a remote on off switch for a computer from a wireless doorbell. I have a pc in my entertainment center which is nice to have a remote to turn it on and off. The relay at the end can simply be wired to the motherboard pins that turns on the computer when they are shorted.

I only needed this circuit because my doorbell rang too long and it would hold the relay closed so long it would hard shutdown the computer (power held for 5+ seconds)
If you find a remote doorbell with a shorter ring you can just put a capacitor in line with the speaker output to smooth the signal out enough to drive a relay directly without it chattering.
Ehh anyways this has worked well for me :thumbup:
