 | | 3V motors
|

Mike, I had a similar problem and the solution is not to put a resistor in series with the motors. With the varying amount of current a motor draws, the voltage drop across the resistor will vary as well and the motors will not see a consistent 3V. (...)

I have a cute little tracked robot base i want to run from a handyboard, but the problem is that it has 3V motors. The handyboard is set up to power 9v, right? The way i see it, i can either just put a resistor in series with the motor to drop the (...) (27 years ago, 5-Aug-97, to lugnet.robotics.handyboard)

Hi, I'm trying to get the ir output on the handy board to power more than 4 LEDs (need to power 6), anything beyond that the ir signals become drastically weak. I have these LEDs wired serially. I'm not too familiar with electronics, so is it (...) (27 years ago, 5-Aug-97, to lugnet.robotics.handyboard)

| | Re: ? mobile base for handyboard
|

Depends on what you want to accomplish. The LegoBug can use otpical sensors to follow a black tape and the smaller 'micro-motors' are better (less play) than the standard 9v motors. check out (URL) for instructions, ordering info and a price list.

| | ? mobile base for handyboard
|
|
Can anyone suggest mobile bases for the handyboard. I am looking for something which is reasonably priced and fairly easy to work with (for a "software" type!). Has anyone used the ARBE-ONE? LEGOBug? Thanks. David Naugler (27 years ago, 4-Aug-97, to lugnet.robotics.handyboard)

Hi! I got to do some test multi servo-motors. I found out the expansion board is not available yet. When will it be available from vendors? I can make a simple test by using #9 digi-input though. best Regards, Mark Kim (27 years ago, 4-Aug-97, to lugnet.robotics.handyboard)

Hi, A few students here at Penn State Abington successfully controlled the Zig-Zag using a 6270 board with both a 6volt and 9.6 volt supply using a .5 or 1 ohm series resistor. If I remember correctly the current is in the 2 amp range when loaded. (...) (27 years ago, 4-Aug-97, to lugnet.robotics.handyboard)

I have that car too but I haven't tied it to the handyboard yet because it gets stuck goin sideways! Does yours?? Have you tried the motor function or just the fd() function. The motor function should be able to slow down the motors. If not, the (...) (27 years ago, 4-Aug-97, to lugnet.robotics.handyboard)
