Bedini Generator MK1
John's original idea is quite a simple idea. Normally a motor can't turn a generator which runs it own motor. But if you cheat by using a fly wheel and switch the motor off every second or so, then the weight of the fly wheel continues to spin the generator when the motors off giving it that little bit extra and charges the battery which powers its own motor.
I tried a simple design.
I used a simple 555 timer to switch a relay which turns the motor on and off, but in my design the generator is always connected.
For my first try I used a wooden fly wheel and small DC motor. Please ignore the timing switch, that was an earlier idea.
After some testing I decided that it would work better with a heavier fly wheel, so I stopped this one and went on to the MKII.
