here is picture (bad quality, cellphone camera) of the grizzly flashlight and the battery canister (disassembled). sorry for the delay on getting the pics up bill. i was on dike patrol, we got a river here in fargo giving us a bit of a problem. things are better now but still gotta keep an eye on them.

edit: this is the first flashlight i have ever owned with a warning on it that "this product may cause gum disease and tooth loss"

@jeanna

Nice scope shot , is that from the mk style cross wind pickup coil ?

@MK1,
Thanks,

That is a half wound but wound with the wire adjacent to each other (bifilar). I found it very difficult to make only a few turns on opposite sides and keep them tight when I connect them across the center.  I made 2 with the same core and same number of primary winds but with the 2 different configurations (this and the cross wind set up).

Over the next few days, I will be sorting out the number of primary turns and how they are wound to see what effect these 2 elements have on the results with the secondary. There is good reason to think the MK cross wind is much better even when not as tight.

Continuing to describe this one, I respected what you discovered about the dead spot, and I wound the 2 wires next to each other to the half way place (right to the dead spot) and went no farther. This means that most of the secondary (60 turns) is on the opposite side (14 turns are in between the primary wires). All that white pick up wire is many layers thick. In the end I was threading it through and pulling tight to get just one more through the center.

It gives average 66volts which is pretty remarkable for such a little thing.

However the one with the cross wind MK style,  gives 20volts off a 6 Turn 2^o. If you multiply that 6 by 12 to get close to the same number of 2^oturns, and multiply the 20v by the same factor of 12 you should get 240volts. I will see if it works out that way. But I will wind it and see. I will not just extrapolate it.

It is just the kind of thing I am doing these next few days, so I am glad you asked this just at this time.

thanks,

Hi Ist,

That is another good video. I have some questions for you. (or anybody)

The frequency meter changed many times showing different numbers.

What does this mean?

What frequency is it telling about?

I am not sure how to ask my question, but that is my best shot at it for now.


A separate question comes up.
I am finding that when I play music and use the scope there is a bit of rhythm that seems to be picked up by the scope.

Is it not better to play the music and the scope separately?

thank you,

jeanna
