Q: How to know if car alarm is armed

[Joe W]

Last night I turned in and left all three cars unlocked. This morning it got me thinking that there must be a way to hack a palmpad into the alarm wire that would transmit a ON command when armed. Anyone give this a thought? I don't want to have HS set the alarm, just know that the car(s) are armed.

Ideas?

I actually plan on doing this, and it's pretty easy to do. Most aftermarket alarm systems (even factory systems now) blink a red LED every x seconds to indicate it has an alarm and is armed. I am sure you can use some cheap palmpad hack to send a signal the first time it sees that LED blink (so it doesn't drain the battery). I also want to do the same thing with my door locks.

I did a How-to on "How to Hack a Palmpad", but it got lost in the latest crash. Wonder if any member happened to download at least the pictures from that thread?

all howto's were saved except for the pictures, sorry

I remember the picture my good friend BSR didn't post, that I wanted to see, was

the smoke when the palmpad was connected to 12 volts
