Testing the TK Tar Baby

It's hilarious. In the Q2 oscillation mode, I think the mosfets are actually dissipating even more power than the load is, somehow.

TarBaby does the impossible!
According to RA, there is no way that Tar Baby's load could be getting warm, because the current and voltage in the oscillations are "exactly" out of phase. Of course they aren't "exactly" out of phase, and she's wrong anyway..... but experiment trumps theory, because Tar Baby's load, the resistors in 250 mL mineral oil..... is sitting at 125 degrees F, which actually is fairly warm. Of course the mosfets are warm too..... Testing Kontinues....

So.... I put together the MileHigh LEDs of DOOM, Special Edition Director's Cut this morning. One addition to MH's design is the small brown inductor (only about 2 microHenry) and the switch. The LEDs are parallel within color, and opposite between colors. (All red anodes together with all green cathodes, and vice versa). The inductor can be switched out of circuit, or in circuit to "short out" the LEDs completely with the small inductance.
Inserting the device inline at the negative battery terminal makes a small difference in oscillations and indicated current flow. No difficulties here.  No white smoke or spalling LEDs yet !! I think she can take the strain as long as we stay under Warp 2, Captain.

With the inductor switched OUT, we see only the green bank of LEDs glowing. This means that only green zipons are detachyfying from the overwhere and flowing into the battery.
However, with the inductor switched IN, we detachyfy a bunch of red zipons from the underwhere and they try to mix inside the brown inductor, and overflow to light up both banks of LEDs.
Unfortunately the LEDs must be preventing the zipons from keeping the battery charged, because it still seems to be running down. At least the reading on my cheapo, not-AC-high-frequency-qualified DMM is going down.
(No bad jokes please. There is already one big one staring us in the face.)
