Otto`s replication of Steven Mark`s TPU

Otto,

Since no one else has asked:

What is the diameter of your 50-turn coil?

Do you have an inductance meter to measure the inductance of this coil?  If not, it can be calculated from the dimensions.  Another way is to use a known inductance value - using the old school method.

What is the length of the wire for the 50-turn coil?  You gave the wire diameter before, but include it as well to keep the information together.

Failed duplications call for more data - such as voltage and current readings.  Place an amp meter in there and get some data.

Renssaek,

Your collector is also twisted to reduce flux. That would have a big effect on your results. However our experiment using lamp wire did not help us achieve anything better.

If everyone wound their coils like a "Brooks coil":

Then this set of "circuit variables" will be about the same.

(One of you has an inductance meter or a known inductor to determine the actual inductance of the coil.)

With the difference in other circuit elements, a little tuning may be necessary.

This will make it easier to duplicate each other's experiments.


EDIT:

Example - using first equation in above link:

With coil thickness of .6 cm, 50 turns - the inductance is 38.2 micro-Henries
(This coil would have a mean radius of 1.5 x .6 cm = 0.9 cm)

Nothing more from Otto? Dang, I was hoping we'd get more details.

I too built Otto's circuit & could NOT get anything to light.

I even tried 100 turns, & still nothing.
