Lego Mindstroms NXT no battery, power by AC plugin

Lego Mindstroms NXT no battery, power by AC plugin Video Clips. Duration : 4.02 Mins.

This is a method to use Lego Mindstorms NXT with no batteries, just an AC adapter. The adapter needs to change voltage from 110 or 240 to 9 volts. please make sure NINE VOLTS only not more. The ampere is recommended to be one (1) or 0.8 A . You can use less but I do not think that the motors will work well. Lastly, discover the positive and negative by trial and error if you need. If you connect the poles incorrectly, no harm will happen (I tried it myself many times). Just reverse the poles and play !! I hope this video was educational and if you need help, please ask.
