Eugene... I mean you no offense, seriously. But is it really a _requirement_ for all "Free Energy" devices to be constructed as if a rat has nested in your parts box?

Consider, please. Almost every circuit can be laid out "Between the rails". Look at a typical solderless breadboard. The positive and negative "rails" are strips running along on the top and bottom of the breadboard, and all the action takes place between the rails. It is very easy to lay out and construct circuits this way, and it makes it easy to analyze them to see just what is happening.

For example, I have been constructing lots of small circuits lately using small pieces of thin plywood for the bases about 6x8 cm, with "rails" made of bare copper wire 1mm as the positive and negative busses. It only takes a few minutes to make such a baseboard; in fact I just made one just for this post for illustration. You can see the 1 ohm current-sense-resistor installed as well as the 2-pin DIP header I use for connection to the power supply or battery. The rest of the circuit is easily laid out between the rails, and I guess you can appreciate how easy it is to lay out following a schematic diagram (which is conventionally drawn out "between the rails") and to connect test probes to the circuit once it's laid out on the board.

Especially with oscillating circuits, the loose and stray wiring can cause artifacts in the measurements due to capacitance and inductance in the wiring, and interference from outside sources can also be easily picked up in the wiring. Of course... if these are the effects you _want_ to demonstrate, that's one thing. But that's not usually the case...

If you could post a schematic for your circuit, including the test points you are using, I would be more than happy to try to build it and confirm your measurements, and it's a great opportunity to show how to use our excellent Rigol scopes to perform trace math and do power measurements.

another rat circuit :P
nothing special some kind of joule thief. what is interesting show glow up led when earth is connected. additional investigation to be done
