Bushbo's server is up again, and yes, the H-bridge file is still there.
However, I just realized how vulnerable we are if someone decides to
stop supporting critical information like this (so I now have a virtual
copy).
This is a great article -- I breadboarded up the H-bridge step by step
as outlined, so I'd learn exactly how it was developed. OK, I lie. I
built the final version and it didn't work, so I started back at the
very beginning and did it step by step. Because I was starting with
simpler versions, there were less things for me to screw up -- and, yes,
it worked.
BTW, there's a typo in Figure 3. The caption is correct, where it
mentions the -ve trigger, but the labels on input 1 and input 2 should
read -ve and not +ve as shown.

and enjoy,
