Hi Xee,
Thanks for the tip.

i was looking at some 0.5v 8amp cells my self
i was thinking of doing 10 in sereies for 5 volt 8amp for usb charging or 5 in series for 2.5 volt 1.2volt battery charging.
i was just going to lay them horizontel with a slit tilt for rain to run off on my wall so they would not be getting full sun this should bring the ampage down but also resisters inline should also drop it to were you wont it.
i think my self 5v at 8 amp be better i could then use 1.2volt battery charger or anything else that might work on usb

You can do it with a simple series of light blubs (flashlight type should work).
It will form a current limiting circuit and voltage drops.  Just pick your output spot.  Three or four blubs will do.

hello

i found 332 volts on the base of the transistor that can be used ..

@ Xee, pretty interesting. One would think since these are meant to suppress they wouldn't work well. They may actually be high perm to catch stray unwanted signals. Some E cores have a thin spacer between halves on the connecting faces that must be kept there or they won't work. One might try to wind the jt on just one 1/2 of the suppressor or E core and on the other side of the same E (past center) of same 1/2 an output wind. Think of winding the 1/2 E like this looking at the E: Pri & sec on the bottom and output wind on the top of this E. Only use 1/2 an E core. Hope that makes sense. The same would be for the suppressor core. Wind what you did and on the other 1/2 wind the output and then snap it closed. If it worked, its much easier than winding a toroid!

@Kooler, In the pic I've went back a few pages and I cant figure the values of all the parts in your pic. It's very interesting. I assume that's a 110 to 24v wall pack transformer. You show the voltage on the cap, but not the cap value and the same for the part going to the xenon tube. Does it light the xenon continuously? I checked youtube and can't find it there either.

Thanks to all for your work & posts.

Also, cutting the line suppressor in 1/2 making 2 that will snap shut may work well in some circumstances. The smaller mass supports higher frequencies for a faster charge & discharge rate. It may lower the output current capability though.

Just a thought.
