(...) 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.

| | 12V batteries
|

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)

(...) Scott The 18200's are a pretty staight forward upgrade. I'm currently using two of them to run a couple power widow motors from a 12V gel cell. They work great. 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 (...)

Rather than fix one of our Polaroids, we want to put one on a rotating platform in front of the vehicle so instead of turning the vehicle to search for targets, we can stop, sweep the sonar back and forth, find a target, and turn towards it.
