In the Handyboard homepage under 6500 polaroid sonar libraries, there is a
great illustration (BRAVO!) that depicts the connections from the HB to
the module that operates the sonar itself. The power supply to the module
(which should be around +5V) is connected via the motor power supply
hookup with 6 diodes in series to reduce the 9V to the required range.
My question is: can I use any +5V / ground connection on the HB
instead of the motor power supply (Our supply is an external one and
uses almost 30V and rather than connecting 30-some diodes in series... you
get the point) ???
Also, Can I use D2 and D3 to control a second sonar module without too
many changes?
Thank you,
Yoni Garbourg

| I haven't seen the schematic you're refering to but I believe you can use the +5V bus already on a standard HB. Just connect your PWR/GND to one of those headers "below" one of the A/D inputs. I did this before and it worked. Apparrently, the 1A +5V (...) (27 years ago, 19-Jan-98, to lugnet.robotics.handyboard)
