TomoHawk Posted January 19, 2017 Share #1 Posted January 19, 2017 (edited) You know those flashing LEDs that you see on cars with alarms or theft-deterrent stuff installed? I was looking at my drawer of electronics junk, and realized I had the stuff to make one (555 timer, resistors, LED, etc.) I made a Printed circuit board ( hate breadboarding) and put the thing together. It worked! I will add some wire to the LED so I can hide the PCB behind the sunvisor, and let the LED hang down near the rearview mirror. But overall, would something like that be useful? Does the fake alarm LED actually deter a would-be thief? Edited January 19, 2017 by TomoHawk Link to comment Share on other sites More sharing options...
Captain Obvious Posted January 19, 2017 Share #2 Posted January 19, 2017 Theft deterrent. Theft resistance. Theft recovery. Does it do anything to help? Well it certainly can't ENCOURAGE theft, right? Link to comment Share on other sites More sharing options...
TomoHawk Posted January 19, 2017 Author Share #3 Posted January 19, 2017 (edited) It's a 1970s car. A 2017 alarm system has no place in it, nor is it compatible, probably. They probably plug into your OBD board. Edited January 19, 2017 by TomoHawk Link to comment Share on other sites More sharing options...
heyitsrama Posted January 19, 2017 Share #4 Posted January 19, 2017 Those blinkies should work nice, but I think using some type of relay that could be removed for the ignition would be cool too Sent from my iPhone using Classic Zcar Club mobile Link to comment Share on other sites More sharing options...
Captain Obvious Posted January 19, 2017 Share #5 Posted January 19, 2017 That would be a small amount of theft resistance. That couldn't hurt either. Link to comment Share on other sites More sharing options...
S30Driver Posted January 19, 2017 Share #6 Posted January 19, 2017 I agree, a small amount. A hidden kill switch on a fuel pump relay is a better overall solution. Link to comment Share on other sites More sharing options...
TomoHawk Posted January 19, 2017 Author Share #7 Posted January 19, 2017 (edited) Right now, I have all these little LED things connected to a 9V in a switched battery holder. It's not really related, but Bruce might get a kick from the chasing lights board I built: it's got a 555 timer and a 4017 decade counter. I should make one up in the shape o f a Z?

S30Driver Posted January 19, 2017 Share #9 Posted January 19, 2017 I think he means disabling the ignition when the led blinker circuit is active. Link to comment Share on other sites More sharing options...
TomoHawk Posted January 19, 2017 Author Share #10 Posted January 19, 2017 There ought to be a simple way to disable the ECU too. I'm just tired of stringing loose wires behind the gauges. Link to comment Share on other sites More sharing options...
heyitsrama Posted January 19, 2017 Share #11 Posted January 19, 2017 Well it just that the blinky is just like a visual confirmation of the system (if it exists) but something that would interfere with the ignition would be a better deterrent. I think ultimately thats what we would want, something that is going to immobilize the car unless its the owner. Link to comment Share on other sites More sharing options...
