    Welcome to A.A.C., Willem! I've removed the e-mail address from your post. Don't want those nasty bots blasting you with spam, eh?

    Can you specify where you need the help most? Is it the control of the pulse width, or is it the switch? Will you want to use a microprocessor or will a manually controlled 555 perform adequately? Will you build your own driver for the MOSFET or use a pre-made one?

    If you can help us focus down on the problem, we will be happy to help you solve it! ;)
