This may sound like a dumb question, but I don't know where to get headers. Digi Key has some but 4 different kinds. The parts list says nothing except 14 pin female header. Nothing else. Where did you get your headers and what are the part numbers? (27 years ago, 21-Jul-97, to lugnet.robotics.handyboard)

Chuck: I agree with you; what I've done with the MiniSSC is to break the path into a set of linear segments with via points in joint space. The lynxmotion arm ends up needing a lot of points (therefore moving pretty slowly) to avoid jerkiness, but (...) (27 years ago, 21-Jul-97, to lugnet.robotics.handyboard)

Hi Fred: The Mini SSC does have a TTL-mode, but it needs inverted data i/o mode. Rather than figuring out how to do that in s/w I just used the MAX232 because it was easy and it made debugging easy into a dumb terminal program on my PC. I've had (...)

Using the Miniboard as a servo slave is a good idea, perhaps even easier is to use a BOTBoard since the BOTBoard doesn't have any motor drivers hooked up to it (no PCB modification required.) Using the MiniSSC is "ok" but for controlling multiple, (...) (27 years ago, 21-Jul-97, to lugnet.robotics.handyboard)

Mike -- Doesn't the Mini SSC have a TTL-levels mode, making the MAX232 unnecessary? Please send your serial output code, though. that would be good to distribute. -Fred In your message you said: (...) (27 years ago, 21-Jul-97, to lugnet.robotics.handyboard)

Hi John: I've used the HB to send serial command strings to a Mini SSC (for the Lynxmotion arm). I built a tiny daughterboard with a MAX232 that plugged into J6 on the board for power. Software handshaking is minimal and the MiniSSC works fine. If I (...) (27 years ago, 21-Jul-97, to lugnet.robotics.handyboard)
