I'm, so sorry everyone but KZfaq muted the last 3 or so minutes of the video :(. I'm not sure what happened as my software still has the audio. I hope you can still enjoy the video and not much did happen at the end anyway.

What a great video very cool well done 👍

information. at 1:50, it IS a DC motor.!!!! NOT a tiny DC generator. when a brushed DC motor is driven, it can function as a very INEFFICIENT (DC) generator. the degree of inefficiency is indicated by this fact: the output is DC. !!! this is 'strange', because, when a magnetic field moves past a coil (or vice versa), Alternating Current is produced.!!!!! it can be seen that there is no such thing as a self-starting Engine. thus, the use of a (small brushed DC starter) motor does allow a single rotary device, to serve two purposes. on the other hand, during part of the time that it is running, the engine Could charge a cap or tiny battery; in order to power its OWN, subsequent, 'start-up'. googletranslate
