one that is quite often over looked is the push pull arrangement used to drive fluorescent lamps in caravans, with a little feedback and control they are very efficient providers of high voltage power. I will dig out a schematic for one i have here. it has been used for laser PSU's, driving neon lam...

sounds like you are the guy to do the filtering then!

This is an attempt to simulate a regulated high voltage supply on Circuit Wizard (cheap sim tool for colleges etc) it doesn't simulate well at all but it does work in real life. the values are not right on this one but you can see what i am aiming for with voltage feedback controlling the 555 astabl...

Yes, i'll post it up in about 10 minutes.

Thanks for the cross reference, I should have though about that :oops: . Personally I think we should make the whole thing as easy as possible with the least number of components that way more people will want to give it a go and it DIY-EFI will be the site for yet another aspect of Engine Managemen...

The ionic current flow will be there at all times even in free air but to a very small degree probably not even measurable by our front end. During compression the number of molecules per unit volume increases as the mixture is squashed into a much smaller space there fore the gap between the plugs ...

Actually I'm in London tomorrow evening and most of tuesday! a colleague and I are traveling at about 1400hrs to get to the Wembly plaza Hilton by about 1700hrs we are staying there for the night and going to a National Instruments LabView expedition in Savoy place, by the embankment. That finishes ...

Its usually the bigger boned individual that craves pies with such a passion!

I think the point of ion sensing is to sense knock conditions before they happen rather than trying to blow the head gasket!

Dave, if you haven't seen this, you should read it : http://www.diyefi.org/forum/viewtopic.php?f=35&t=193 Yes i read that quite some time ago, but i can't help but try to pull in some of my own data and see what is there in real time. I note the requirement for an AGC for the front end this wou...
