Hi,
I'm considering a locator for my slow stick. I searched quite a bit, and found a bunch of good ideas, but none that are really what I was hoping to accomplish. I don't want something that beeps continuously if signal is lost - since it could well be within earshot of a neighbor and I may be coming back for it later on, with the needed supplies to rescue it from a tree. I've got an unused channel on my current setup that I was considering using for a bomb-bay door, but this may be a more practical option for that channel. I'd like to be able to sound the alarm (and silence it) remotely. I considered a generic finder such as this http://cgi.ebay.com/uPager-Key-Finder-Locator-find-remote-purse-wallet_W0QQitemZ320305881835QQcmdZViewItem?hash=it em320305881835&_trkparms=39%3A1%7C66%3A4%7C65%3A15%7C240%3A1308&_trksid=p3286.c0.m14, using the wallet module that is only 4mm thick. My concern is range and volume - it may not have enough range to be useful, and "up to 90dB" isn't overly promising.
Some of the personal alarms seem like they could work, but rigging the servo to push the button or switch could be a trick, and whatever trick I devise could be knocked out of alignment by a crash. The type that work on a pull-cord basis would be easy to activate, but impossible to silence. Something like this http://cgi.ebay.com/Personal-Safety-Protection-Keychain-Alarm_W0QQitemZ180292381117QQcmdZViewItem?hash=ite m180292381117&_trkparms=39%3A1%7C66%3A4%7C65%3A15%7C240%3A1318&_trksid=p3286.c0.m14 combines a flashing light with an alarm. Perfect, if I could activate it remotely. Unfortunately it's hard to tell how that one is activated and deactivated.
Also, are the wires from the receiver to a servo a constant source of power? Could I perhaps connect 2 of those leads to an alarm in the proper volt range, and have the alarm sound when I moved the stick on the unused channel?
Any advice/input appreciated.
Thanks,
Dan
