Hi everyone, The mistake you make in your calculation is that in your calculation you take the entire 15V for the resistor and this leaves no voltage for charging your NiCad. Do the same thing again and deduct your NiCad voltage from the 15V you (...) (26 years ago, 14-Nov-98, to lugnet.robotics.handyboard)

You could use resistors to make a 1/10 voltage divider. If you need high input impeadance, you could build an Op-Amp circuit to divide the voltage by 10. Most ADC chips have a pin that is the reference voltage for the high end of the scale--set this (...) (26 years ago, 13-Nov-98, to lugnet.robotics.handyboard)

greetings to all i dont know if it has been asked before, but im trying to use son extra ADCs on my handyboard, trouble is they have a 0 to 5V range (analogue) but im trying to adapt the signals in the ranges of 0 to 50 volts, how do i make them (...)

(...) 3 Watts is correct. Look at the resistor on the HB charger board. It's pretty hefty too. -Scott (26 years ago, 13-Nov-98, to lugnet.robotics.handyboard)
