Piezo transducer

Ludic gets 20 volts from his Piezo chip. When we scale the magnets or copper mass up in the oscillator, it adds to the striking force of the hammer.Last edited by Allen Burgess; 12-09-2018, 04:19 AM.Comment

A little centering and over 2 volts of multiplied output;

I added two neo disc magnets to the stator and wrapped two elastic bands around the rear Piezo and generated a steady 120 volts. Next I'll try and light the flouresents.

Piezo output D.C.?
On Piezo output from vibration:
"Depends on type of mechanical 'excitation' used. If persistent value force is used, a constant DC voltage source is generated".
The 120 volts is D.C.Comment

The D.C output from this piezo chip should illuminate 66 3 volt LED's in series. This is close to the ratio the tester achieves in the speaker video with the 100 LED's in resonance.

Pi/po
Working the 500 Newton (100) lbs. of force electro-magnet with doubled over elastic bands and Neo disc magnets increases the vibration force but also eats up a lot of power from the wall socket.
Simply attaching the piezo chip to the upper back end of the vibrating stator comfortably generates around 3.5 A.C. volts. The piezo generator requires a diode and capacitor to rectify and store an increased charge that can illuminate perhaps a bank of 3 volt LED's. This would match the voltage from the BEMF.Last edited by Allen Burgess; 12-10-2018, 11:52 AM.Comment

Analysis
Forcefully "Whipping" the piezo transducer on the tail end of the oscillating steel rocker generates high D.C. voltage.
Imparting a "rippling wave action" at the resonant frequency of the chip generates an extrodinary amount of voltage (+200).
There's over 100 pounds of attraction force exerting torsion on the piezo chip in that fluttering position. We may not find a better output approach.Comment

30 LED's 1 Piezo chip
Look at the illumination strength this tester is generating by just pinching the chip between his fingers! The fluttering transducer should light 100.

How do the magnets in attraction attached to this electro-magnet and stator effect the flyback? When the current is interpreted, the magnetic field in the electro magnet coil collapses from the outside in. That's the same direction the converging permanent magnet fields in attraction travel when they reconverge.

Double implosion
The regauging permanent magnetic field is pressed right up against the collapsing magnetic field in the coil that opposed it after the current is interrupted. The output is A.C., primarily because the re-penetrating field is an opposite polarity of equal force. Both events transpire within the tiny time frame that the contact points are connected, shorting the coil through the SPDT spring pressure switch.
This oscillator does the job of inverting input like a Ruhmkorff Coil without the secondary!Last edited by Allen Burgess; 12-17-2018, 07:25 PM.Comment
