Kramble, that's an impressive piece of kit. I haven't read the entire ~150 pages , but that's about one of the coolest pieces of kit I've seen on this thread. It's not about the MH/s, its about getting stuff to work. Hat's off to you! Way beyond my "Electrotech 101" which is some 20 years old now back in college where we'd blow up a capacitor/inductor or two :-)


To the person who was interested in 10 port USB hub, this one works good (and is cheap)

Don't know if you can get it in the US, but 21 pounds works out about 30 USD - but shipping from England would be heavy I would think.
