With the modification mentioned in the the FAQ, can you power 3V motor at 3V with external power? The FAQ mentions external 6-36V and L293D spec sheet says that the minimum Vs is Vss (which has a minimum 4.5V). The modification doesn't change Vss, (...)

(...) I too talked to Customs and they are typically confused and confusing about import tariffs and such. I was told that the limit was £19 for what that is worth. I would probably just order the damn thing and see what happens. Tax probably won't (...) (27 years ago, 7-Aug-97, to lugnet.robotics.handyboard)

If you try to regualte the voltage to 3V You will still loose the extra power as in using a resistor. You lose it in the form of heat to be specific. Using a regulator will give you the 3V you need at continuous output. I'm not sure how voltage (...) (27 years ago, 7-Aug-97, to lugnet.robotics.handyboard)

Does anyone know if the hb LCD is classed as reflective or transflective.If it is reflective is there a transflective counterpart(i.e. one that can be backlit)? Thank you, Joe Martin Email:joema@mpx.com.au (27 years ago, 7-Aug-97, to lugnet.robotics.handyboard)

Yes, it is true that altering the duty cycle does not alter the voltage. What it does do it alter the amount of current to the motor. The problem with these motors is that they draw too much current, more than the HB can readily provide them. By (...) (27 years ago, 6-Aug-97, to lugnet.robotics.handyboard)
