Good stuff sobil.
the hardest part i think would be the winding of the toroid
Maybe not...atleast it doesnt ask you to wind 1,000 turns

Ive tried winding 250 turns for a project once and kept loosing count
Try this you might find something in here :

I though the hardest is getting all the parts required. I havent read it all yet but it look like the PSU is specific.
Good luck and let us know it goes
