Pulsed DC Transformer with Embedded Magnets

My last workship at Hong Kong University on Oct 9, 2010

I shall run my last workshop in Hong Kong before going back to USA.  The date will be Oct 9, 2010.  For those who want to see the whole process of winding the toroid, making the Joule Thief, they can come at 11:30am.  For those who just want to see the results, they can come at 3:30pm.  The workshop is free.

The Workshop will cover:
1.   Theory of Lead-Out Energy
2.   Making the Joule Thief
3.   Enhancing the Joule Thief
4.   Resonance hunting
5.   Feedback
6.   Use of the two oscilloscopes

The Demonstrations will include:
1.   A one-second flasher that has run for 6 weeks on one AA battery
2.   A similar flasher that runs on a solar cell key ring toy.  With recharging from sunlight, the device is expected to run forever (or until parts fail).
3.   Lighting of 108 LEDs for 6 hours on one AA battery
4.   Possibly lighting of a Christmas Tree on a solar cell key ring toy
5.   Possibly taking out the batteries and the two LED FLEET will still be on for at least 30 seconds

The future workshops in Hong Kong will be conducted by others.  The task of developing and showing a 1kw FLEET device in Hong Kong will be left to the younger teams.  They will shine.

According to your explanation, this is what I understand.

Minde  Your theory on the blocking diode is a good as anyones.    I can't see how Stan could create higher EMF force except by using harmonic push/pull and forced decay.  This would give only one place for that force to go,  thus the fluid medium is the absorbant.  So a blocking diode would only allow at best one half the power that should have been available.    And Minde do you have a project anywhere we can view on HHO?  OR ANYTHING?

Mr I, Thank you for your sharing your Hong Kong adventure with us!

More to share on Feedback

One surprising thing on Feedback was that the polarity back to the Power Supply did not seem to make too much difference.  One connection should recharge the battery.  The opposite connection should supply current in the same direction as battery.

The Input Vpp was about 800mV with no feedback.  With feedback:
1.    Connection A lowered the Input Vpp to 200mV.  With adjusting, the Input Vpp varied from 170mv to 400mv.  The Output Vpp varied from 6.2V to 10.0V.
2.   Connection B lowered the Input Vpp to 230mV.  With adjusting, the Input Vpp varied from 160mV to 360mV.  The Output Vpp varied from 4.6V to 7.6V.

Both values dropped the Input Vpp significantly.

*** Will rework the JT battery charger.  With the standard JT charger, both batteries will drain down after a couple of recharges.  When we configure the JT in the overunity state, we managed to observe both batteries rising in voltage.  However, if we leave the charging on, the system drifted to the underunity state.  Now with feedback from the secondary side and the charging at the JT output side, we may be able to use some lead-out energy to recharge the batteries and keep the charging at the overunity state.

*** Will experiment along such lines.

Hey  ltseung888

How is it going?   Have you shown a circuit yet?    I pop in here once in a while.

Hope all is good
