Hi Guys and Gals

I've just joined after following this site for a while to ask if i could have some help
building a Variable flyback driver,
as I'm a bit of a n00b with some forms of electronics and don't have a large budget for new parts i need some help building it to be rather robust.
the only drivers I've ever done for flybacks are using CFL light bulb circuits.

I'm looking for the power to be very variable from the lowest i can go with a flyback transformer to the highest you can @ a variable mA if possible.

ANY help will be gladly accepted and any advice too

thanks,
Tom Williamson.

A TL494 driver is pretty good, I did make a complete new version of this instead of the one in this thread, but the driver section is the same, look at it for some inspiration...
