@All,
Pay attention to the videos...... If your after heat anyways! Look.......

Now THAT, is some kinda plasma! Time to cook.

@All,
I ran the SEC-15-3, with the modifications for heat, for a couple of hours last night. It sustained this operational set point or "tuning" and continued to maintain the temperature of the neon at 121F (49.44C). 20.XXX VDC(voltage climbs and falls approximately 0.6 VDC as the circuit runs) 29ma input current (rock solid for the duration of the test). As Dr. Stiffler pointed out the device is very stable in this configuration with no noticeable detuning by picking it up or approaching it with a hand. Further note that the 22uH chokes are almost the same temperature and now it is becoming difficult to isolate individual components for relative temperature measurements because everything that is even close to the Neon is getting very warm indeed. The calorimetry runs will be very interesting I suspect. So the hard work is in progress.  The next challenge for me will be stable operation in the calorimeter, I do believe, and accurate data acquisition. 

CAUTION IF YOU ARE REPRODUCING THIS!

This will burn your finger or other body parts that come into contact with that Neon!

@Dr. Stiffler,
I take it you have designed this to operate at optimum heat output without the need to take into account the light radiating from the neon for COP determination? Is the energy radiating as light a significant percentage of the total power budget? Otherwise the increase in just the light is very significant from subjective observation. The entire interior volume of the Neon is plasma and bright Red-Orange is a very accurate description. Nice work! I can't wait for my temp sensors now! 

See the pictures.

@Yucca
Excellent work, but what I might ask is do you feel that this method does not require calibration? In other words I might be inclined to have a calibration resistance in each side and power both for a cal period to be sure there is no offset from the two sides, then would use that offset in the final calculation??

Of course, I hadn't thought about that yet. Thanks for the heads up.

Q)Would aluminium foil backed cardboard work for the SEC heat mod or should I scrounge some thicker metal?

@Loki,

WOW, nice cooked finger! Hard to believe 1/2watt input power did that, I've been messing with 1Watt resistive heaters and they just hurt a little but no physical damage like that.
