Hi Bill

well done!!

I love it, its exactly what I'm after for the odd camping/ fishing trip.

Have you thought about making a step by step guide from the Fuji Mod to where you are now with the double LED lights, I for one would like to see something like this and probably many others, as I'm currently only on page 120 of this very long thread and would love to make it while I'm trying to catch up to you all.

Thank you very much, I really appreciate that.

You know, I have been asked that before and, as you will see as you read this topic, there are 2 main variants of the Fuji board....an AA battery board and a AAA battery board.  All of my successful projects were done with the AA board.  Jeanna discovered a way to tell the difference by the outside of the camera....the AA board has a black switch on the front, like a rocker switch and the AAA board has (at least it USED to) a green slide switch with little bumps on it.  By the way, these all come in the same box with the photo of the AA board camera on the front of the package.

Well, I bought another camera the other day and opened the box in the store and it had a black slide switch with little bumps on it and this was a AAA board.  I have messed with it for hours and can't seem to get it to work.  I am just hoping that the AA boards are still out there somewhere.

It would take a lot of time and patience on my part to make this type of video but, I do agree one should be made.  I have been asked many times.  I'll see what I can do IF I can locate some more of the AA boards.  The rest of it is easy and the Fuji mods are not really that hard either.

These make great little lights and I have been having a lot of fun with them.

I think you are correct about the AA fuji boards being a little scarce now days, I have been collecting used cameras now for a few weeks from the local shop and all up I have around 20 Kodak of various models and about 5 Fuji's all AAA, I have not seen any Fuji camera's for sale in my part of town, but will keep seaching, If I can find some I will help out and make the step by step, as I am finding out the info to get to your stage is spread over a very long thread.

Anyway keep up the excellent work, we are all having fun here even though some of us can only light 20 or so LED's.

I just remembered....I had purchased 2 Fuji cams about 10 months ago.  I finally got around to trying to make something with them, as seen in my latest video additions, and even though they were AA boards....the traces were a bit different and I had to get an older one of my mods to look at and figure out where to hook up what.  It was not that bad, but it was different.  So now I know how to make 2 different Fuji AA variants work.

As we discussed way back (yes, I went back last week and was re-reading about our Fuji posts to get some help)  The size of that transformer on the AAA is very small compared to the one on the AA boards.  So, I will always try to hold out for those AA boards...IF they are still around.  Who knows?

If I can help you in any way, just let me know and I will try.  Josepino.com has a good piece on how to do the "standard" Fuji mod....all we really did different from him was to cut the anode end of the diode to get the full wave.  He said that all he could light was the small 4 watt tubes and, as you have seen, we have done much more than that.
