Connections for SIRCS experiments.
For those who were able to join in today, thanks for your attendance -- I hope you enjoyed it as much as I did. I have updated the files in the post at the top.
For those who remember my frustration/irritation with the sensor detection not working (when I know I had tested that), the culprit turned out to be my logic analyzer.
For those looking for a very low-cost logic analyzer, this is what I was using today.

It has such a low price tag that I couldn't NOT try it, and it has been very helpful (today's irritation notwithstanding).
For the capture displays (I've attached a couple) I am using the freeware program PulseView. It is x-platform and quite nice. I especially like the wealth of protocol analyzers.

Looking forward to the next session where we'll be talking long-range remote control through a standard RC transmitter and using the S.BUS protocol to get all our channels through a single IO pin. This is the hardware I used for testing:

... but any RC receiver with S.BUS output will work.
I just got an update of program 04 from Kevin -- the young guy who is good with robots. We found a small gotcha, but have that fixed, and now the program reports TV and DVD remote buttons accurately.
Jon,
I bought one of those CANNOT RESIST very low-cost logic analyzers months ago. Just haven't had the time to get it out of the bag
I would rather get the P2 to do something similar but fear that's a looong way off for me.
