alternating strobes for my car - Electronic Circuits Projects Diagrams Free

jakethepython · 22nd April 2003, 03:29 PM

can someone help me. i need to build an alternating switch for my car. i want it to be able to run 2 strobes at differnt times. so while one is blinking the other is off and it goes between the two every 2 seconds or so. i know how i would do it from a 555 timer. but i need to somehow do it from a car batterie which would blow the hell out of the chip. can anyone help me find a shcematic for such a thing?

Isn't the 555 rated up to 9v? This may explain it!

Otherwise, are you using the output of the 555 to drive trigger tranformers?

555 is rated up to 16V. Bear in mind, that a car's system voltage can rise up to about 15V, with the engine running fast.

For circuits, search for "555 astable".
