Blinking LED "Car Alarm"

10/30/2010 12:05:46 PMTerry Decker

I notice that most new cars with a sophisticated alarm system have a blinking LED somewhere on the dashboard. I occurred to me that I could "arm" my '92 Ford Ranger by having one of those.
I live in an area where there is some vehicle vandalism.
So I guess I'm looking for an oscillator circuit that would run on nine volts. I have plenty of information for blinking neon bulbs, and I could probably buy what I need from Ramsey. I just figured it'd been fun building something from my junk box.
Thanks-
Terry

Sir Terry. . . . .

Decisions . . .decisions . . .DECISIONS!

Been using them for years to make others think that I have alarm systems.

On one more involved applications installation, I had the LED's mounted right beside door locks and deck lid lock positions.

Been just as well pleased with the initial Flip Flop circuit as the more complex units, I tended to shy away from
the '555, just from the basic aspect of maintaining simplicity.

On the later, referenced circuits, they can really be driving the LED hard, but just for milliseconds, as 10 ms seems to be just a very FAST blink while at ~100ms, that is being of long enough duration to have the retina make a full perception of it.

AND . . .IF you have an adequately power rated LED , like the Luxon family, you can simplify to the use of one of those "christmas tree" bi-metallic strip flasher lamps.

Flashing Neon Lamps ? . . . . . I have one of those built up (~40 years ago) on the face of a 1 foot square walnut cube/w/ brushed stainless steel faceplate, with 100 NE-51 lamps mounted on 1 in centers, as s--l--o--w relaxation oscillators.(Seems like each R timing element was a 10 meg resistor, and I for sure remember, that the caps were .68 ufd, as a few failed over the years.)

To inquiring dummies . . . I then explain that the "instrument" is a random cosmic ray particle detector . . . that then has them all worried and quaking in their boots. LOL.

Terry,
You can get flashing LEDs at the Shak, ready to go.

Thanks Marv-
You're right, I forgot about that. Still, I'd like to play around with one or two of Edd's circuits.
