Hi everyone, I've hooked up the QRB1114 infrared sensors to the analog input ports. Although they appear to be operating, their values make little sense. Whether a black or white object is placed in front of the sensor, the Handyboard reads in a low (...) (26 years ago, 19-Feb-99, to lugnet.robotics.handyboard)

I won't attempt to power your servos with 9v. Those servos are designed to work off a 4.8v battery pack, you'll most likely smoke'm. Wayne -----Original Message----- From: J.W. Pennington <jwp@awod.com> To: handyboard@media.mit.edu (...) (26 years ago, 19-Feb-99, to lugnet.robotics.handyboard)

First, The Handyboard's motor output is 9 volts, does anyone know if Futaba's small servos handle this well? I have two S3003 servos that I'd like to use. Second, Has anyone run a solenoid from a motor output? I'm assuming that it would do fine, PWM (...) (26 years ago, 19-Feb-99, to lugnet.robotics.handyboard)

Does anyone know a good place to purchase the MC68HC11A1FN chip? I haven't found a single place. Motorola doesn't seem to sell them... neither does BG MICRO. Jon (26 years ago, 19-Feb-99, to lugnet.robotics.handyboard)

(...) Many optically black materials do not at all affect the IR range of the spectrum. It is possible that your black object is not black (read "absorbant") to IR and simply reflects it just like the white. Try several different materials. Many may (...)

I'm trying to implement a hardware shaft encoder routine similar to the the one described in the Mobile Robots Book for my Handy Board. I'm using the pulse acumulator for the left encoder and TIC2 for the right shaft encoder. They are both (...) (26 years ago, 18-Feb-99, to lugnet.robotics.handyboard)
