Here is a (poor quality) video of my prototype attempt to understand how these things work. Absolutely nowt that I could find of any use trawling the web, so did it all by trial and error, using 'junk' from around the workshop, including magnets, coils transistors and stuff. I must admit I am pretty pleased with the result.

  • @thegreatbunsofstone Yes, no such thing as perpetual motion where I come from!

  • Here are some clues. An electro magnet in the base is energised to REPELL the magnet on the bottom of the long arm, fed from a power transistor switched by a reed switch closed by another magnet set into the long arm as it passes.

    Good luck if you are having a go, and be patient, you WILL work it out given enough time and patience.

  • Can you make a video on how you made it. that would be Great

  • @bennie18181

    Don't take this the wrong way, a video WOULD be Great wouldn't it, but I'm afraid you will have to guess how it's done, like I did :-)

  • It is all about getting the balance right, you have to add weight to the top end until it is only slightly lighter than the bottom, that way it will swing much slower. Good luck!

  • You are correct about the magnets, repelling to give the small arm a kick as it passes, as for the weighting, many evenings of head scratching and tweaking till I got it working well.

see all

  • Just one question, is this one battery powered as well?

  • come on man give us some more hints. You mentioned that you used transistors and coils. for what purpose did you use em. Did you made and electromagnet with that or something else. I would really love to build and see if i am able to make it work.

    Anyways a job well done building it. 

  • Very nice.

  • im working on my own but mine spings sooo fast! plz help!
