You cannot use one of those infrared temperature meters to read with any degree of accuracy when the emissivity of the surfaces or distance is different. Often you will get  a difference between two readings when measuring the same surface / same distance.

Matched Thin film Platinum 100 Ohm resistance film sensors used in a differential bridge circuit would be a better choice when trying to differentiate one degree or less.

Also the cores will take quite some time to heat up as the loss is in the copper wire, which is not efficiently  coupled to the cores thermally. At this low frequency (3200Hz) with metglass, core loss / core heating  is hardly an issue.

Furthermore, digital temperature sensor systems often respond erratically when there are "frequencies" being emitted by the DUT.

one year into the future.  tk caught in a photo riding the jetson scooter down his street while still denying this is a valid device.

One  could always try it. 

I was thinking how easy it would be to try to make an SFT.
Then one could see if it has any anomolous gain at 50/60hz frequency.

Then one could build a box chain;

(1) -> (2) -> (3) -> (4) -> (5) -> (6) -> (7)

(1) 12vdc rechargable (acid lead) battery
(2) double throw double pole knife switch for self looping
(3) 25Watt cheapy cigarette lighter inverter 12VDC -> 120/240 50/60hz.
(4) step down transfomer 120/240VAC =>  12VAC 50/60hz & plug from RS
(5) 50/60hz SFT Split Flux Transformer see below
(6) diode bridge rectifier
(7) 12VDC incandescent parking lamp, dummy load

misc 1000Uf 25WVDC or more electrolytic cap., 560 ohm resistor, LED

Goal: to see if you can get the current into the inverter @12VDC less
then that going into the  bulb @12VDC and if voltage is ~12VDC =>  get rid of the bulb
and run wires back to the switch for self-run test. nKuf Cap across switch.
You may have to try several different inverters to get an efficient one,
small inverters are very inexpensive these days.

Build a symetric SFT - Experimental Split Flux Transformer

(1) Get three spools of 24guage project wire from Radio Shack
(2) obtain both ends of the wire from spools
(3) punch some holes in the plastic spools
(4) glue and wire leads on all three coils
(5) Get three large diameter muffler hanger ferrous U-bolts with hardware from auto-supply store.
(6) Put one leg of 2 U-bolts through each coil center hole.
(7) Put on header brackets and screw down nuts,  not too tight.
[8] Mark primary and sec1,  sec2 coils
[9] Connect series sec1, sec2 considering coil phase.
[10] Done - this needs to work at Low VAC 50/60hz.

See if it will work.

Anyone buy the Jetson bike yet?  Steeltpu?
