Merv:

Thank you very much.  As a matter of fact, the E.B. is on the list for one of my next videos.  I need to re-work my connections and such but, it is still out there and, even though I have not used it in a bit, I believe it will still work fine.  We will see.

Thanks again,

Bill

Nice Box!   is it one you had or did you buy it and where from?

[Pirate88179]

Thanks.  It was one I had that used to hold a set of pin gauges.  All I did was stain it a bit darker.

I did find a possible source for similar boxes at reasonable prices, although I have not ordered from them yet.  See what you think:

I know these types of boxes are very expensive at my local hobby shops.

I used my last 3.375" diameter ferrite toroid to make another Lidmotor/Jeanna light circuit.  330 winds on the secondary with 3 winds on the base and the pick-up coil has 13 winds. (22 ohm resistor)  I am able to run two Lights of America 4 watt bulbs. (25 watt equivalent for each bulb)

I mounted the project into one of the wooden boxes I ordered from the link I posted in my previous post.  These are nice little boxes for a cheap price.  I could not make one of these boxes for anywhere near the low price.

I will have to find another way to make some high voltage for these circuits as to buy another 3.375" toroid is about $50.00 (US) now.  These used to be available for just a few bucks each.

I am thinking about attempting to drive this unit with a special battery i have from one of my flashlights.  It is a 18650 3.7 volt 3,600 mAh Li-ion battery.  It will fit inside the case easily and I think (hope) that the TIP3055 transistor mounted on a huge heat sink will take it ok.

Any thoughts on this?

I can easily run my other Lid/Jeanna circuit light on 3 volts and the cfl is a lot brighter when I do this.

I guess I just can't leave well enough alone.
