 | | Fried analog port
|

I was taking some measurements of sensors by reading the value on the LCD display. Suddenly poof a burst of smoke came from the analog port (0). Now the only reading I have on that port is 1, but the other ports are fine. Could I have somehow fried (...) (27 years ago, 13-Apr-97, to lugnet.robotics.handyboard)

| | HB Simple Encoder Routines
|
|
Hey everyone, My partner and I are trying to use the sencdr?.icb and fencdr?.icb routines to keep position measurements of a robotic arm. The encoders are break beam and provide a signal of 4kHz max. We used 4 J-K flip flops to reduce this frequency (...) (27 years ago, 13-Apr-97, to lugnet.robotics.handyboard)

I once saw something like this, but it was very complicated to build. There were TWO separate arrangements of your wheel descriptions, and they were hinged from a set of "hips". I believe this is because, as wheel 1 is pivotting over the front edge (...) (27 years ago, 13-Apr-97, to lugnet.robotics.handyboard)

(...) That's exactly the stuff. I saw a demo of this in class, so I can't give you specifics, but it's the sort of experiment that takes about 6 minutes to try on your own. Note, however, that there are a few different kinds of the foam: i mean the (...) (27 years ago, 12-Apr-97, to lugnet.robotics.handyboard)

Volts = Resistance X Amps Using the traditional I = current (they say it comes from the French word for Intensity) R = Resistance E = (...) (27 years ago, 12-Apr-97, to lugnet.robotics.handyboard)

Postscript files are generally for printing out. Therefore, you send a postscript file to a "postscript printer". Most HP Laser Jets are. Otherwise, you can use a program called GhostView. It's a viewer that has postscript capabilities. I think it's (...) (27 years ago, 11-Apr-97, to lugnet.robotics.handyboard)
