Well, I didn't win the set up off ebay anyway! Oh well, probably a good thing! Instead I picked up an electronic distributor for a fraction of the cost. There's some very interesting sounding stuff flying around here, makes me realise just how complicated a project it would of been! Thanks for the t...

The problem is that the delay is usually expressed it terms of degrees of crankshaft rotation. This would require a circuit whose delay is both a function of an adjustment pot, but also inversely proportional to engine speed. ...oh... One thing you should keep in mind i think is that when the engin...

Thanks for the quick summation of the 555 timer, seems to be the sort of thing I'm looking for. With regards to it being a 5V or 12V signal, would be amazed if it wasn't 12V, but will have to ask the question I suppose! Relocating the disc encoder/reader on the dizzy is the way you're supposed to se...

lol, read that 3 times, and it's still predominantly greek!

My electronics knowledge really is abismal - bit of faffing around at school, etc - so I'm afraid I don't understand much of that...

I'll go google flip flops, as they sound promising! :grin:

Slowing/retarding a signal pulse

Hi guys, Just found this place after having an idea for modifying an electronic distributor ignition system. The system works with a photosensor detecting a break in a beam of light from an LED, when a fan-like object spins over it. As each blade passes through the beam, the signal is broken, and th...
