[SEL] replacement ignition designs

[Elden DuRand]

George:

I'm sorry but you are about three years too late for one of the production models.

Stay tuned.  When I get a chance, I'll design a simplified version in a do-it-yourself kit.  I don't know if I want to go to the expense of having printed circuit boards made, so it may be a rat's nest configuration.  You supply the box, the battery, the coil and the labor and I supply the rest.

I'll have to experiment to see how long a lantern battery will last.  That would eliminate some up-front cost (gel-cell battery and charger).

Since I quit the business, I've designed several other versions of the ignition system.  Some of them are very simple, using only one chip and a MOSFET transistor and the other parts to make it work.  

I've always believed that you should be able to use just about any high tension coil for my systems and my ignitions will  successfully drive anything from a little dinky weedeater mag coil to a big old battery-type point-type coil.

Take care - Elden
