Interresting book from Lindsay

List,
Lindsay publications has a book out that might be of interrest to some. I'm
not related in any way to them but I've ordered books from them before and
been pleased. It's a book on EDM.

Some may enjoy, I'm thinking of ordering a copy. If someone can come up with
a schematic for a digital power supply to do the job I'd be interrested in
that as well.
Thanks,
Lindsay Durham
