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)

Simon, This shouldn't be too difficult to create...but it could be a real waste of memory unless it is real important issue. The reason why is that you would have to save the messages in memory. You'd have to decide if you wanted to fill all the (...) (26 years ago, 15-Jan-99, to lugnet.robotics.handyboard)

(...) Yes, and it is totally trivial to do so. I don't have my sources here at the moment, but it is roughly like this: c = readknob(); /* or whatever the cmd is for reading it */ if ( c < 64 ) { print "a"; } else if ( c < 128 ) { print "b"; } else (...)

I apologize for having sent the following with extra line-feeds in it; Here it is again: The main problem I see is with how you label the voltages at various points in the circuit. If you have a 12 V battery, the low voltage end is usually called (...) (26 years ago, 15-Jan-99, to lugnet.robotics.handyboard)
