Hello hxtasy, just come across something that looks as if it might work Opto-isolator,4N25 5300Vac/60mA DIP6
If I read it correctly I can input from the phototransister and pass a 12 volt current through it, I hope ! t ogive you a laugh what I would do is order a few and test it practically...
Hello hxtasy thank you for the information on the e-type I guess that I get at 6500 revs x 6 cylinders approx 650 pulses per sec which the race logic setup ( race logic is the recording equipment ) and it records the 12 volt spike and with some input from me ,just inputting a conversion number...
Thanks hxtasy, the system is that is used is for the old cars with coil ignition and it uses the 12 volt pulse from the low tension side for that ( works fine on my old, 1964 lightweight e-type ) but on my 1969 porsche it has electronic ignition fitted with dual ignition system and I think that...
thanks hxtasy will take some looking into or is there a way just to use the 5volt supply to switch an external 12 volt supply ( from the car ) on and off to give me the 12volt spike
cheers
Hello
Please my apologies for mistakes as I am a new member, and I would like to ask a how to question,I am trying to make a system up that I can use on my racing cars ( classic hence no onboard computer )
What I want to do is to have a 12 volt pulse(from 12 volts to o volts) that I can use on...
