Greetings Tropes. Well its 1.30 am in the morning here in Victoria - Ozzie land. I'm about to turn in after a long day.
I've started up a simple site which is aimed specifically at beginners and addresses some minor points about your Hall problems.
Heres the link. - http://www.totallyamped.net/adams/index.htm

Hope the info is of some use to you.

Its just the beginning so be prepared to be disappointed. I'm gonna go have a quick hot milo before I turn in.
Cheers from hoptoad  :)

What's a "hot milo"?

Sorry Tropes the link should be  http://www.totallyamped.net/adams/index.html
Hope this works
A hot milo is a sort of hot chocalate drink nade from malt yeast and some other exotic ingredients that really is a great night cap.

Cheers

Great job Toad. I've added a link to your page on the circuit site.

Okay Toad, Ren and I are using a PNP transistor. The circuit you show uses an NPN. Is there a circuit using PNP transistor that would make the Hall switch less prone to damage?

toad you are the man. Required reading for anyone using halls above. Oh yeah, go the milo. 5 parts milo to 1 part milk, its the only way

Tropes, my basic understanding is that a pnp and an npn are very similar, the only difference is the way the current flows, hence connections. In our pnp setup you would hook the firing coil up to the emmiter, as opposed to a npn where you would hook it up to the collector. Look at the link I posted in the other thread regarding pnp and npn, and anyone please correct me if I am wrong.

So hoptoad, could I place a variable resistor between + and the input to hall to limit current flow to hall? Will this have any effect on switching time/duration? By that I mean can I vary the resistance to the hall to vary the on/off time, much like you would do with a pick up coil (see Bedini setup)? Or would just a simple resistor be more suitable. My halls are 3-30 v rated. Thanks again champ.
