@ Jeanna:

Excellent news!  So, now you have 3 AA boards......good!  If you go back a few pages, maybe more, there are plenty of photos, explanations, etc. on the AA boards to hook up correctly.  If you have any trouble, let me know.  If I make any progress on the AAA board, I will post it right away.  It would be good if you can find a slide switch like Jose used (and me too) as it makes it a lot easier (and safer) to experiment with.  I found one in an old, cheap, cheesy flashlight.  Mine is 3 position but I only used 2 of them, it still fit nicely.

I think I agree with xee2 about the copper surface switch on the AAA boards.  I removed mine and I think I will either short it, or look for a switch I can install there, or on some short leads. If that does not work, I will try Wilby's approach.  Maybe I should flip a coin?

I think I will contact Fuji and tell them not to make any more AAA boards and stick with the AA board design.  I am sure they will listen. Ha ha.

Anyone here think I should try for 400 LEDs?  It is tempting as they are only about $5.00 on an after Christmas sale.  I can't fit any more on my tree but, they are good to have around any way.  Since they are the icicle style, I was thinking that if I get the clear ones, they would make a good night lite spread out on a wall and held up with push pins.

I found this on the net.  The parts are labeled.  Thought it might help.

This is the schematic that goes with the previously posted pics above.  I don't know if this is the same as the one posted way back on this topic by someone or not.  This may help.

With that circuit you can try this simple configuration.
