Pictures of the new generator set up and a theory question from Thane:

Here is our new coil test prototype.
And here is a question for all the armchair theorists out thereââ,¬Â¦
The Gold ââ,¬â€œ high current wire slows the rotor when shorted
and the Gold ââ,¬â€œ high voltage coil on the same core accelerates the rotor?
Why?

He's doing different things with them. It's not very clear exactly what the setup is but making some deductions from Thane's post:

1. He's shorting HC3 to produce a deceleration - but it's unclear whether it restabilizes at 700rpm or is still slowing down. I'm guessing it stabilizes because he needs to have time to take the current measurement on HV2

2. HV2 is showing 100V and 0.5A, which means it's not shorted (otherwise the voltage would be zero). It appears to have a 200 ohm load attached to it, rather than being shorted. V=I.R

So we wouldn't expect the two coils to have the same effect, since one is shorted (zero ohms load) and the other has a 200 ohm load. Also, we don't know whether they have the same number of turns or not. Again, if I've deduced the setup wrong I'm sure Thane will be kind enough to correct me.

All,

Update to low cost test equipment research in blue:

An article to buy an accurate digital Tachometer using a magnetic sensor for less than $25 at http://www.instructables.com/id/Tachometer-made-from-a-bicycle-speedometer-cycloc/. The Cateye unit used in the article is not available anymore. I found a newer version, which is a Cateye Velo 8. Got it today, set it up according to the article and it correctly measure the two speeds of my Ryobi drill.
It was $22.56 including shipping from BikeWorldUSA.com.

An article on building a Gaussmeter for as little as $6.00 at http://my.execpc.com/~rhoadley/magmeter.htm. The hall effect IC in the article is discontinued. The replacement is the Allegro A1323LUA-T. Digi-Key has it for 1.45.

Wanted a low cost Wattmeter that can measure milliwatts. Couldn't fine one, so I've ordered the Kill-a-Watt meter for $21.49 including shipping thru Amazon.com. Displays active power and apparent power in whole watts.

Larry

NO SORRY - 100 V OPEN AND THEN 0.5 A WHEN SHORTED.

So we wouldn't expect the two coils to have the same effect, since one is shorted (zero ohms load) and the other has a 200 ohm load. Also, we don't know whether they have the same number of turns or not. Again, if I've deduced the setup wrong I'm sure Thane will be kind enough to correct me.

YOU ARE WAY OFF BUT I HAVE AN EVEN BETTER IDEA THAN CORRECTING YOU HOWARD
- COME TO THE LAB AND CORRECT YOURSELF. HONESTLY LUC AND I WOULD LIKE TO MEET YOU.

HERE IS THE QUESTION AGAIN...

1 HIGH VOLTAGE COIL (270 ohms) CAUSES ACCELERATION WHEN SHORTED
1 HIGH CURRENT COIL (55 ohms) CAUSES DECELERATION WHEN SHORTED
THEY ARE MOUNTED ON THE SAME CORE
SO WHY ARE THEY PRODUCING DIFFERENT RESULTS?
I HAVE MY IDEAS BUT - I WANT TO HEAR FROM OTHERS.

FOR ANYONE WHO IS INTERESTED THERE IS THE FULL INTERVIEW HERE FROM KEY RECORDS. http://www.megaupload.com/?d=ECN1N26Y
