Dissimilar metals testing 1 (Jan./Feb. 2005): Volta's contact law says that when two dissimilar metals are brought into contact with each other, a voltage appears between them. Testing was done to see if this would make a difference if the metals were brought close together, as may be happening in the testatika when different metals are rotated close to each other. Results: There was a voltage fluctuation. However, as was learned with the small machine testing below, this may be a normal result of variable capacitance which you may have with the same metals too.

Testatika pots as capacitors theory 1 and testing (Mar. 2005): Theorizing and testing were done regarding what might be in the testatika pots (cylindrical grid capacitors). Results: This testing unexpectedly found a way that lower voltage DC output is possible if high voltage DC is the input. The testing also had some low voltage AC riding on the DC input which was amplified. This is all possible if there is ionization in the air between one of the capacitor electrodes and the output grid. This ionization provides a current path which is the source of the DC.

Small Machine testbed 1 (Mar.-Jun. 2005): Replication was tried of one of the small machines taking an approach of testing and learning about each component as it was added. Testbed 1 was the first version but it suffered from a disk that wobbled too much. As well, due to lack of experience using an oscilloscope to measure something that had a floating voltage (neither electrode grounded), all the measurements were done incorrectly - one of the electrodes was always unknowingly being grounded.

Small Machine testbed 2 (Jul.-Aug. 2005): Improvements were made to testbed 1 to create testbed 2, making it possible to eliminate much of the disk wobble and adding other adjustability improvements. From this, and by using the oscilloscope correctly for floating voltages, a better understanding was gotten of what was going on. Results: The purpose of the disk in this machine is to be a variable dielectric for all the grids that face the disk. These grids act as variable capacitors, their output being an alternating voltage (something that has long been suspected). The following diagrams illustrate this and the experiments can be found here.

Two other results are illustrated as follows:

However, the design of testbed 2 was still too unstable as the wobble would return if it was knocked too hard, resistance was an issue in the back grids, and other problems made it so that constant readjustment was needed and the same precise measurement could never be gotten two days in a row (though the electrical behaviour was consistent). The main problem, though, was that only about 20mV to 50mV spikes were gotten from of the disk. At least 700mV was needed so that a modern diode could be used to charge up the grid capacitors. Creation of diodes by wrapping coils around magnets (see Tesla's US patent 413,353 "Method of Obtaining Direect from Alternating Currents") was tried but none of these efforts produced any rectification.
