12 times more output than input, dual mechanical oscillation system !

[Garethfine]

Hi all.
Well this has been a very interesting topic up to now, save for the lack of working experiments. I've never posted before but you'll see why i decided to today.

You gotta see what my brother built last night. I went over and made a video of it and took some pictures. Very interesting ideed, but I have to say, we didn't find anything remarkable in the design.

Some notes:
There is a particularly large effort involved to get the pendulum swinging initially (easily forgotten)
Subsequent pushes on the pendulum could be compared to the output on the wheel of the bicycle, except that the lever stops moving when there is a small load on the wheel.

See for yourself and comments will be welcomed.

Will post the video in the next reply because this keeps failing. It 12Mb.

There is a little detail stated on: http://www.veljkomilkovic.com/OscilacijeEng.html

QUOTE: "The best results were achieved with the lever axel and pendulum at the same height, and the base of the massive lever above the centre of mass, as shown in Figure 1."

From your picture I don't clearely see how this is achieved (you maybe carefully consider it though). However, I'm waiting for the clip and your comments.

OK here's a video

It's shown the system, and briefely the whole oscilating thing.
It's suppose to be in resonance, and in short periods from clip, to me it looks not "tuned" on the same frequency. It might need you to play with the arm lenght and/or weights.
I'm not to much in mechanic engineering but I think this was to reason to use the simulator in previous posts: to find an optimum.

Secondly, the chain mechanism is not a reductor (like the speed gears)? If so, it's normal to have less power and more speed.

Good luck and don't give up!

Hi all!

PESWiki updated the article about Milkovic's two-stage oscillator and here is what is new:

"The input coil consumes 1 amp at twelve volts at approximately a 20% duty cycle which comes to around 2.4 Watts. The output is between 200 and 300 mAmps, at between 14 and 15 Volts, which comes to around 3.5 Watts AC (sine wave)..."
