New hack - Alarm as a relay control board?
After seeing the latest alarm that AsianWolf was selling I did a little background research on it. It is rebranded as several other alarms, and some offer an option of connecting to it via a PC! Scktek even offers a PC link for the alarm! http://www.scytek.net/pdf/ScyTekWiza...ationGuide.pdf
The supplied software dosen't look like it would do a lot for you, but if you could reverse engineer the protocol, it would seem that you could build something semi-realtime based on the alarms inputs and outputs. Of course, the computer would have to stay on all the time.
Some of the things that came to my mind was:
Camera on when preimeter sensor triggers
Autostart of the vehicle for cooling
MP3 alarm chirps depending on the situation
Automated defense (ie sensor triggered and GPS shows movement, trigger this thing: http://www.stopthecrime.com/prod-repulsar4.htm)
Anyone else interested? The alarms can be had pretty cheaply and I'm sure the cable can be RE'd to reduce the cost of entry. The number of channels might make this a pretty cheap and easy relay board if the protocol can handle a passthrough trigger from the com port to the relay without dependance on an alarm trigger.
