 | | resistors w/motors?
|
| I'm curious - can I limit the voltage to a motor by putting a resistor in series with it? What are the pros and cons of this solution? I have a bunch of low voltage (3V) motors that I'd like to be able to use with the handy board, but giving them (...) (29 years ago, 4-Feb-96, to lugnet.robotics.handyboard)

| (...) That's a definite possibility. However, I'm looking more for something that has a tread-type drive system, though two independently driven wheels is fine. That allows me to simplify steering the robot, so that I can rotate it at a point. (...) (29 years ago, 4-Feb-96, to lugnet.robotics.handyboard)

| (...) How about buying a $15 RC car from radio shack and adding a $15 servo to do the front steering? I haven't tried it. I'm using RC-10 cars and they're GREAT. Independent suspension, hispeed, good traction... but several hundred dollars. -- (...) (29 years ago, 4-Feb-96, to lugnet.robotics.handyboard)

| Keith, You may have shorted something out while connecting up the battery. I've seen this before, and parts do fry if you connect them to 9.6v.

| | | | | hmph
|
| Ironic that, just as I write a message looking for L293 drivers, the motors I was driving with them should fail. Unfortunately, it seems that I overpowered the small DC motors I was using, and burned the brushes to bits. :-( So perhaps I should (...) (29 years ago, 4-Feb-96, to lugnet.robotics.handyboard)
| | | | | L293 chips
|
| I'm still searching for a pair of L293B chips. (Though I guess that Ds would work as well...) In the meantime, I'm overloading my L293Ds, which become extremely hot during operation. (Wonder how much life I'm taking off of them... I need to find a (...) (29 years ago, 4-Feb-96, to lugnet.robotics.handyboard)

| It is now time to think about reording more parts, or just bailing out all together. Please tell me if you will need any parts in 3 or 4 months and what the amounts may be, you are committing yourself. I just need to gauge if it is worth having (...)
