Steve I would try these people this is there contact information. They do sell Hall Device igition systems.MJN Fabrication 3330 Neal Acres Rd., Dover, FL 33527 telephone (813) 719-3220 web site http://www.mjnfabrication.com Ignition systems for model IC engines. Otto Gas ...check it out you might find what you are looking for.Don
Hi Steve,You could look into the earlier Harley ignitions. They had twin fire coils operated by points. That might work for what you're doing. gbritnell
Insure you have proper heat sinks. Don
Steve - If you insist on using an old style bipolar transistor as the switch - have a look at the Bosh BIB373. It's admittedly not easy to come by, I only found two outlets on the net. Unlike all the other old style high tension transistors, it has the necessarily gain to ensure that it can easily be controlled by an MCU or a Hall sensor. It also contains all the necessary protection circuits - but it's not cheap ($7-8). Oh, I forgot to tell, no one designs anything with a TO-3 or has done so for more than 20 years - they are too expensive, takes up too much space, etc.
Hi GuysWould something like this serve for my V8 project?On a good Day I can just about work out a simple single cyl points ignition system, but its a streach I hope to use a Hall system for the first time on this.Thanks guys.Pete
