Thanks for the well wishes. The trip went very well. I just wanted to give you an update that the list of PCB tools that I mentioned has been posted here in this blog post. Come take a read and let me know if I missed something that you were looking for.
Paul-I am glad that you found it useful. I do have a program as you indicated. I will be submitting a piece for the new PCB Design line here once I get back from my trip. In fact I am at the airport right now.
A good Digital scope will allow you to "see" digital streams, A/D steps and resolution. Also there is really no differentiation between digital and anlog signals since ALL digital signals have finite rise and fall times, ringing, etc. so when you get down to it all signals are analog.
Now there are special multi channel logic analyzers with built in I2C, SPI, CAN, and other serial protocol analyzers, but these come at a high cost if you REALLY want to see the analog component of the signals.
I have to admit that I frequently have gotten away with crimping with a standard pair of needle nose pliers and a small chisel and hammer. Because I am mostly building personal stuff this has not been an issue. I would love to hear about a good set of crimpers that covered a wide range of devices for under say $65. I realize that is asking a lot as many specialized crimpers are in the $200+ range.
