bought at Radio Shack and you don't have to open up your radio receiver.
Here's an example of how to rig your pager or phone to reset your PC:
Buy a phototransistor from radio shack ($1.50) and some black electrical tape ($1.50?)
1) disconnect the wires from the "reset" button on the PC, and solder it to the phototransistor.
2) tape the phototransistor so the detector faces the pager or mobile phone LCD. Tape it up
real well so that no stray light leaks through.
Activating your pager or cellphone (via incoming call or txt msg) will trigger the backlight on
the LCD which will, in turn, cause the phototransistor to pass current.
With a few more parts (surge protected power strip, relay, perfboard, project box?)
you could apply the same concept to temporarily interrupt power to your devices.

Try searching for 'watchdog timers' or 'dead man switches' that can automatically reset a PC or access point if it stops responding. There are some pre-built devices that can do this, or you could build your own. I'm trying to come up with the latter...

I'm looking for any references/info on projects or products that employ the paging network for remote control of unattended devices.
I'm interested in building a simple switch to power cycle remote wireless nodes. There is a product on the market for $375 [http://www.nighthawksystems.com/nighthawk_nh2.asp] but it also seems like one could build such a device rather easily with a pager, a relay, and some minor soldering by hooking up the vibrate motor to the relay input.
This got me thinking, though that there might be a lot of cool things that can be done remotely with pagers & unattended devices. Google is not producing much, but maybe I'm not using the right terms.
Please reply off-list, I'll compile and post anything I find.
thanks in advance
