Nope. I get all my chip information from datasheets, mostly from
Motorola. They also had some great design information on-line, but
sadly, since they restructured the company, much of it has disappeared.
That leaves me with whatever I downloaded.
There are HC chips, HCT chips, LS chips, and many more, but I can't find
an HCTLS chip.

Include some good information about adding sencors to the walker. There are now quite a few excellent tutorials on 2 motor walkers, but they finish after you get the thing to walk. They don't discuss what you should do next.
I think you should also discuss HOW the walker is expected to walk, because I know when I was just a beginner, I had trouble understanding how it was supposed to walk (until I built a few) and also explain a bit about the feedback and the micro/bi core's reaction to it.
