(...) By ground, I just meant the HB ground. The important thing is just that everything in an electronic system share the same ground; voltages are relative, and the ground is just the shared reference point--the point arbitrarily defined to be (...)

Never done it before, Alf, but here are a few hints. First off, learn about the IDE interface. These CD-ROM drives are cheaper than SCSI. Also, try to find source code for a CD player on-line, and examine it to see how it works. Last, why not just (...) (26 years ago, 16-Jan-99, to lugnet.robotics.handyboard)

Hi all! I got a question. Whenever I connect the motor outputs to a scope (I wanted to read the output of the HB), the LEDs light up even with the output off (ao())... Can anyone explain this to me? Thanks. Keith (26 years ago, 15-Jan-99, to lugnet.robotics.handyboard)

In the example, are there any advantages or disadvantages in using a voltage regulator (such as a 7805) to dropping the voltage from 12v to 5v as opposed to using a diode string? Also, I guess no one had an answer on the earlier question of running (...) (26 years ago, 15-Jan-99, to lugnet.robotics.handyboard)
