Neat. I still have my iPaq somewhere in the garage. Doubt it powers on anymore, but it worked when I last put it away. That thing was sweet. I mean, how many handheld devices did you know about that could take TWO PCMCIA cards?

It's pretty amazing what people are able to do today with relatively mundane tech.

Granted, Mark has specific knowledge and skills, but I'm sure many people have similar education (not to detract from Mark, this is a very cool solution, just that there are lots of "Mark types" out there these days).

Even what can be done with an older RPi, or a cheap controller, etc. So much capability for just a little effort and a few dollars.
