Of course, yours isn't the first such device to hit the market. For
example, there's this one (and it's just one of many) --

Though it's a bit heavier (7g vs 4g) and a bit more expensive ($15
vs. $10.) It will also tell you about a battery whose voltage is too
low, however. All in all though, yours seems fine to me (from what I
see on your web page anyways), though the chip on your shoulder may
turn off some potential customers.

Other alternatives include :

And here's instructions for building your own --

(Though at $10-$20 each, I'd probably just buy one.)

Can your device be triggered if you have a receiver that never stop
sending the servo signals, even if the transmitter is turned off? PCM
and some of the newer DSP receivers sometimes never stop sending
signals to the servos, even when the transmitter is off, and some lost
plane alarms only trigger when that signal stops, which means that
they'll never go off with one of these receivers.

Just being an EE doesn't make you a better solderer.

(It also doesn't seem to help with capitalization or punctuation.)

And some people never learned that this is Usenet, and the old adage
of `if you don't have something nice to say about somebody, don't say
anything' has been replaced with `it's better to be thought a fool
than to open one's mouth and remove all doubt.'.
