 | | Re: Batteries again, sorry
|
| you're almost right. if you plugged a nimh pack into the HB's charge jack, the external pack would charge the internal batteries. but it would not power the board significantly. this is because the HB's charge jack includes a current-limit resistor (...)

| | Re: nimh batteries
|
| the issue with nimh is that plain trickle charge is not appropriate. you must remove charge current when the cells are full charge. the HB charge circuit just doesn't do that. i'd really recommend switching back to nicad. fred In your message you (...)

| | Re: Sensor supply voltage & PC communication
|
| hi. you can certainly tap the 9.6v batt output to power the sensor (use J13), but make *sure* that the sensor does not put out more than 5v, or you'll blow your analog inputs. if you're not sure, put a 1K resistor in series with the sensor's output (...)
