For Those of You Electrically Gifted, (I'm Not!)

Unread postAuthor: mark.f » Wed Dec 27, 2006 8:14 am

I've been looking into electrical ignition systems for the past few days to help a buddy of mine out. I was considering a few circuit designs. First was the familiar "buzzer" design, which worked, but was rather weak. Then, I thought of this:

<img src="http://i10.photobucket.com/albums/a123/markfh11q/fcircuit.gif">

My question, first off, is if something like this is entirely operational and practical at the same time. The second question would be some optimization ideas and specifications. What type of resistor would be best for this? I know it depends on what type of capacitor I'm using, so I WILL say I'm using one out of a camera, which is poled. Therefore, I know my reisistor will have to be biased off of this. My question is what type of resistor?

If you don't see what's going on here, the capacitor is dumping in a complete circuit through the transformer through the resistor. This causes the resistor to "switch" the current back and forth to an alternating current, which flows through the transformer and steps up the charge on the load side. I call this the "capacitor/resistor" effect, (don't know what it's really called :oops: ), and I know it's used a lot in the electronics biz.

All help is greatly appreciated. Thanks!
