Crystal Cell Research for Experimenter

@Tgraca Have #30 wire will wind . how to you like you pocket Oscilliscope? I was looking at the DSO 201....

It works great. It's light and easy to move around from work area to work area... and its cheap, so if I fry it, it's not as big of a deal
as frying one of those big machines. I hope you enjoy that kit... I don't have the patience for a kit, plus the blue one is only a few
bucks more and will probably hold up better to dropping it... my meters take a lot of abuse. I think everything I have is "technically"
disposable for that very reason.

The JT circuits couldn't handle the power of the crystal cells, so I had to add resistors while the cells settle down...

10 mH for the inductors is too much for this circuit and requires a resistor... I tested the various inductance needed for this circuit
and this type of battery build, and it seems the best light I get is from 1/2 to 1.5 mH for the inductors. I'll wind a few today to
determine the number of winds needed with 1/4" bolts as a core. I might make a video showing some of my experimental biFilar
coils built around 1/4" bolts to demonstrate how to get more inductance out of fewer windings... thus making easier biFilar builds.

Also, since these 4 circuits won't work with these 2" crystal cells, I may make a 1" crystal cell to see how that works with these 10mH
JT circuits. The key considerations I am working out is cost of JT versus cost of crystal cell. The 470 uH to 10 mH inductors cost
the same on eBay, but when winding them, fewer winds is better.... and obviously, a 1" crystal cell with this type of build will cost
about half as much as a 2" crystal cell.

Here is a graph 4 cells I made F149 mix i could only zap with 12volt battery because it kept tripping my 30v power supply.
This test is open air meaning not sealed like Fausto's, I'm doing that next.
The load is a white LED, I'll do the same one the sealed one . Next tests will be 100 ohm resister afterwards.
Also have a kit on order from my China friends to measure inductance.[size=78%]http://m.ebay.com/itm/251609065467?txnId=1566142715015[/size]
This is called "Battery 1 F149"Im going to let rest for a week til I activate with the epsom.

Isn't interesting how this graph is totally different than the ones I have been showing?


Good work.

Fausto.

I wound a few transformers this morning... here's some fun information on what I have learned over the last year...

I am always looking for a cheap and effective material to mold my own cores for transformers, but this stuff is relatively expensive....
If you decide to experiment with it, please share your experiences!
