(...) Most Connor disk drives have a 68HC11A1FN on them. If you find someone throwing one away, it is a cheap HC11. (...) Digi-key sells these. (...) Ben Wirz sells these. Also look for the TI replacement possibly. (28 years ago, 19-Mar-97, to lugnet.robotics.handyboard)

Hi, Does anyone have recent model #'s, part #'s, or suppliers for Hall Effect magnetic sensors that interface directly with the Handy Board. There is a picture of a Hall sensor on page 52 of the Handy Board Technical Reference, but no part number or (...) (28 years ago, 19-Mar-97, to lugnet.robotics.handyboard)

(...) I just looked back to the IR transmitter schematic... The 1K res + RED LED you see there is for the only purpose of having a visible feedback of IR transmission. The IR Led and it's limiting resistor (if the case) will be connected in series (...) (28 years ago, 19-Mar-97, to lugnet.robotics.handyboard)

Does anyone have experience using a Truly MCC162A1-2 16x2 LCD? I bought one from Wirz electronics for the handyboard. In assembly step 6.something, it says to power it up and there should be *faint* segments lit, if they are dark check pin1 to (...) (28 years ago, 19-Mar-97, to lugnet.robotics.handyboard)

(...) How are you gonna get 100 ma through a 1k resistor biased by 5volts?? The max would be 5ma. I have *never* heard of a LED this size that can handle more than 20ma!! This LED is tiny. I don't know where pin one of the jumper goes to or its use (...) (28 years ago, 19-Mar-97, to lugnet.robotics.handyboard)

(...) I think it must better be a darlinghton and it must support enough current: if you want to get 0.1A or more pulsed current in the IR led, the transistor must have a rather high current gain, more than that of an ordinary npn trans (by the way (...)
