Hey Everybody, Quick question for you. Just bought two Polaroid ultrasonic ranging modules, and I would like to know if I must use the Propulse batteries and holder that the manual suggests. If not, does anyone have any suggestions for a substitute (...) (28 years ago, 13-Dec-96, to lugnet.robotics.handyboard)

I am new on this list and I wander if anybody can help me with information about a supplier of 'Handy Board' with a reasonable price; the ~$280 it's excessively high for me. Thanks Gyuri (28 years ago, 13-Dec-96, to lugnet.robotics.handyboard)

(...) I concur here, I have a 6inch X 6inch piece of aluminium for 2 of them, and this seems to dissapate all the heat I am generating. I could see longer runs or steeper grades would require a larger heatsink. (...) I was the one who originally (...) (28 years ago, 13-Dec-96, to lugnet.robotics.handyboard)

I need a source for a good 12V battery. I'm thinking gel cell to keep the weight and size to a minimum. I found a 12V lead acid at Radio Shack, which is a good size but it's too heavy. My current needs should be modest - a couple of stepper motors (...) (28 years ago, 13-Dec-96, to lugnet.robotics.handyboard)

Hello! I'm looking for feedback on my proposed modification of the HB. I need to drive a 2amp motor with 24 volts. I don't really trust the 754410's to handle that much power (not to mention the handyboard traces). What I'd like to do is replace (...) (28 years ago, 13-Dec-96, to lugnet.robotics.handyboard)

They get hot pretty quick, so a heat sink is a definite must. Scan through the (...) (28 years ago, 13-Dec-96, to lugnet.robotics.handyboard)

| | RE: laser diodes II

Any laser diode will work for sensing objects. The trick is that they are _so_ bright that you can't just look for the reflection (unless your are sensing objects at a few hundred feet) There was a Circuit Cellar contest entry which used a laser (...)
