Prototype A uses 20 turns of Joule Thief type winding in the clockwise direction.  The 0.5mm transformer wire was used.  A multimeter was used after the winding was complete to determine the correct connection.  In the diagram, the small white label papers at the toroid have the numbers 2,4,3,1,6,5 counting from the top.  Wire points 2 and 4 are jointed as required in the Joule Thief Circuit requirement.  One pair of wire is 2-3 and the other pair is 4-1.

Wire point 1 is connected to the 1K Ohm resistor which connects to the Base pin of the 2N2222 transistor as specified in the basic Joule Thief Circuit.  Wire Point 3 is connected to the Emitter pin.

The 1.5 V AA Battery is connected with the positive end to the joint 2,4 wire connection.  The negative end is connected to the end of a 1 Ohm resistor which is connected to the Collector pin.

The Wire points 5 and 6 are created by a continuous clockwise winding on top of the 20 turns of Joule Thief winding.  Initially, the number of turns were too low to produce the required effect.  It was then increased to cover the entire toroid.  The new configuration worked.  This was the only tuning used for this particular prototype.  No variable resistor, capacitor or inductor was used. 

This happens to be one of the simplest and robust prototypes.  However the COP is low compared with the best tunable ones.

It is extremely important to have the two oscilloscopes connected properly to get the correct results.

Check the connection with the following diagram carefully.  The most common mistake is to have 3 and 4 reversed.  Most Oscilloscopes have common ground between Channel 1 and Channel 2, the incorrect connection will create confusion and worthless readings.

With this Prototype A, the Output Load is a LED, a 100 Ohm resistor and a 10 Ohm resistor.  The 10 Ohm resistor is chosen instead of the 1 Ohm resistor because we need to have a large enough voltage measurable by the Oscilloscope.

The draft information for the qualified verifier on Prototype A is complete.  May God guide him and provide him the wisdom and the skills to perform this historic verification.  Amen.

I have put some comments on Experiment 6 in the attachment.

God is bringing us closer and closer to the solution.
