  • I got a question, I built this but when I turn on the power supply only a sound is heard but sometimes only one side of the lifter flies but others just a lightning occurs between the aluminun foil and the cable, how can I get this work, is for my science fair and its on thursday please help.

  • Maybe too late, but problems can be:

    The lifter is too heavy.

    Your power supply is not powerful enough.

    The corona wire is too close to the base foil.

    Any point or sharp corner in the upper area of the foil causes vibration in the corona wire. Keep the foil as smooth as possible there.

    Put a large high-voltage resistor in series with the high-voltage terminal to avoid sparks.

  • The board is a switching power supply, generating +12 V and +70 V. The breadboard is a flyback driver in development. The high voltage output is connected to a ball electrometer, and has a resistor (5M) in series with the lifter.

  • @GNaranjoN well i suppose its too late, but its most likely the top thin wire is too close to the foil (you said its arking over)

  • sweet. you mechanized the string on this one. now there's some brilliant thinkin.

  • That music was classic... especially when the chorus kicked in!

    On a serious note, your video is a good demonstration of a well built lifter.

  • Great work Antonio! Question:

    Can you describe all the equipment? I see two breadboards (printed circuit boards)? What are those? I really appreciate the great video post!
