as has been discussed on this list, the Handy Board wasn't really designed for three volt toy motors. Reducing the voltage and doubling the motor chips is a reasonable approach, however. The Handy Board requires 7.2 volts to operate, because of the (...) (28 years ago, 1-Mar-97, to lugnet.robotics.handyboard)

Hi, This is in response to the question about motor voltages posted earlier tonight. Check out the archives. Late last week I posted a similar question and got some good responses about wiring the HB for two power supplies and using diodes. I have (...)

Hmmm. What voltage and/or LEDs are you using? Assuming 5V, your LEDs age passing only around half a milliamp of current. I am using a 100ma LED and I can only get less than a foot of detection. Am I missing something here? Jun Nolasco (...) (28 years ago, 1-Mar-97, to lugnet.robotics.handyboard)

(...) Those are the IR LED's - the one's that transmit the IR light that the receiver sees. Also, while I'm at it, I found out that the diagram above isn't completely accurate (I drew it from memory). The circuit I really use is like this: (...)
