Hi all, has anyone used the Quality Technologies infrared sensor modules listed in the HB Technical reference? The QT (www.qtopto.com) site indicates an 'optimal' test range of .050 to .150 inches. Can they detect *at all* beyond these distances? (...) (27 years ago, 29-Jul-97, to lugnet.robotics.handyboard)

Hi there, I've just finished installing the serial communications hardware on the board itself and am on section 4.4.2. in the assembly manual. I was just wondering, should the green SER LED on the Handy Board and the green PWR LED on the Handy (...) (27 years ago, 29-Jul-97, to lugnet.robotics.handyboard)

I've just got hold of two hamamatsu photoreflector(part #5587). I got them as samples from the company. It came with no data sheets, so I have no idea on how i can interface them to the handyboard. I plan to use them as shaft encoders. It looks like (...) (27 years ago, 29-Jul-97, to lugnet.robotics.handyboard)

Billy, (...) Make sure your defaults are right. Type "DLM" with no args to see the possibilities. You want -256 and -mb. In the future, please use the robot-board list, *not* the handyboard list, for Mini Board questions. See below for info. -Fred (...) (27 years ago, 28-Jul-97, to lugnet.robotics.handyboard)

Anthony, A couple of suggestions, the handyboards dual servo routines are not as stable as one might like (the timing it tricky). I would suggest however that you put a separate battery pack on each bank of servos, since each bank can draw 3 amps (...) (27 years ago, 26-Jul-97, to lugnet.robotics.handyboard)

| | Re: I2C Counters
|

How many counts, how fast are you counting? Can the LSBs be dropped? What I'm suggesting is using a clock/calendar or clock/calendar/RAM such as the Philips PCF8583. Input your wheel pulses instead of the oscillator. You scale by 256in one mode, (...) (27 years ago, 26-Jul-97, to lugnet.robotics.handyboard)

Does anybody know if there is such a thing as a binary counter that will work on an I2C buss. If there is such a thing it would sure simplify a few circuits. I'm already using the SPI lines to control a few I2C DACs. To monitor motor/wheel RPMs I (...) (27 years ago, 25-Jul-97, to lugnet.robotics.handyboard)
