Circuit setups for pulse motors

[Ren]

good healthy debate, but Jase is right. We are here to improve and share our techniques. Hop toad let me ask you this. Are you skeptical about setups which apparaently charge more batteries than they consume?

Jase, you said you charged a 12 v off your setup. What was the circuit? Car battery? Were you just filling a cap from emmiter and collector and connecting the charge battery to the cap? How long to charge? And have you done any experiments with pulsing the power out of the cap into the charge battery or do you just let it flow?

@ tropes, good stuff with the mj's let me know how they go.

@ hoptoad. Perhaps you could offer a suggestion as to how tropes and myself could stop blowing halls. We use a simple hookup method which is posted in this thread I think, my diagrams are in the old thread. I have been told to install a diode between base and emmiter. How does this help/protect the circuit? Could we place a pot or resistor between the power and hall to limit current and offer tuneability?

I could not imagine an Aussie and an American peacefully resolving a conflict but you ( Jason and Hoptoad) came close. Good on you!!!
About 9 years ago I taught myself enough HTML to build some websites (4). I now have two and use one of them mainly for storage. I have a folder on my desktop marked "Circuits04" and it contains the circuits that have been uploaded to this forum. I will upload these to a site so they can be easily accessed and will continue to do this as we accumulate more.

BTW, I also draw "pitchers" http://www.theowlnest.com/looking.html

Hi All:
   The deal with the Hall device is you are hitting it with stray voltage spikes. From experience
they dont like that at all. I call them flaky myself. They do work quite well but... No you can use
a voltage regulator to power them with directly with a bypass cap on it. Also you can put a small
amount of resistance on the output leg to the transistor to limit the amount of current you can
draw from it. Read the tech sheet on them to see what the max current is and then figure out how
much resistance to use and still send the transistor into full turn on state.
   This is the reason I like to use mosfets for switching with a driver feeding them. Real fast turn on
times. Into the nanoseconds. Hope that helps you all out in the quest.

Thanks for the info Thealin.
I uploaded some of the circuits to http://www.theowlnest.com/circuit.html
If you would like a circuit on this page upload a jpeg or gif to this thread or point out its location and I will put it on this circuit site.

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
