(...) yup, it was too short! (...) Phil, couple of questions for clarity. Does it need to go up and down the steps or just up? does it carry stuff? Why is step climbing needed?

No, you can't use PWM outputs that swing from about ~10v-~4v for *digital* output. However, you can pull the 74HC374 (see motor output schematic) out of socket and put a 16pin ribbon cable(rat shack) in the socket. Then take the other end to a (...)

If you can use an I2c chip, then the Motorola MC68HC11E2 has 2k of EEPROM and costs about 8-10 dollars. You can try contacting Motorola for samples if you are a student I have heard they are free. You need a school letterhead signed by a proffessor. (...) (27 years ago, 11-Apr-97, to lugnet.robotics.handyboard)

So, I saw the Scientific American show on PBS and I was completelly geeked! It was too short. I was most impressed by the tennis ball capturing contest and by Newton Lab's Vision Car entry. Cognachrome is very cool. After seeing the show I logged on (...) (27 years ago, 11-Apr-97, to lugnet.robotics.handyboard)

(...) I believe the wattage just tells you how much power the resistor can reasonable dissipate. Therefore using a transistor which can dissipate more power than what the design calls for is alright, but using one that dissipates less power is bad. (...)

I have a question on the replacement of the a specific resistor. On the handyboard there is a 3.83K 1/8W resistor. I just received in the mail the last pieces for the board and was shipped a 3.83K 1/4W resistor. Is the wattage citical on this (...) (27 years ago, 10-Apr-97, to lugnet.robotics.handyboard)
