I have tried to use my servo with the HB, but the icb that I have does not reflect the documentation in given in the HB manual that I have. There is reference made to servo_on() and servo_deg() which is not in the icb file that I have of the servo. (...) (28 years ago, 13-Mar-97, to lugnet.robotics.handyboard)

Digikey is out of stock of the ztx614 transistor. Can anyone tell me another supplier for this transistor? Can I substitute a different transistor? If so, which one(s) would work? Thanks! .... Jim Montague (28 years ago, 12-Mar-97, to lugnet.robotics.handyboard)

| | Spike protection
|
|
Does anyone know if the motor ports on the HB are spike protected? I would like to actuate a relay from a motor port. Normally a diode across the coil kills the spike, but I was wondering if the drivers on the HB already handle that. Thanks, Terry (...) (28 years ago, 12-Mar-97, to lugnet.robotics.handyboard)
