Congratulations @lasersaber!!!!

I'm confused about the transformer and its function/schematic.  Can anyone post a link to a datasheet for this or a similar transformer?  I'm likely missing the obvious, but I just see a primary with two leads and a secondary with four leads and I have no idea how the secondary is wound, let alone anything about the core material, ratio, etc.  Seems wide open.

Thanks!

The transformer appears to be an aa version fuji or larger size than the aaa fuji. Its actually a primary with a center tapped secondary so 5 wires . the sixth connection is open . SO two are the primary and three are the secondary . Maybe a better schematic can be made so other camera transformers might work .i will trace out the aaa transformer when i complete the replication . I want to use leds instead of a cfl bulb . Good work lightsaber and thank you for sharing !

The only reason i didnt use a center tap on the circuit is becuase i thought it had 2 secondaries. But the library has a center tap IF thats what it is.

If its just a center tapped secondary it makes it very easy to replicate by almost anything. There is nothing special about these transformers. They have a little ferrite core so they can handle higher frequencies for charging the flash cap.

In fact you can use  ferrite ring like a joule thief. Wind about 100 turns of thin wire, loop it and twist for a center tap then another 100 turns for the secondary. Then make a 10 turn thick wire primary. Almost any decent ratio to give some volts should work it depends how long you want to sit there winding coils!

Thank you bolt . I didnt mean your schemitic is wrong . i can read it and apply what i know about those transformers . I remember way back in the jt thread we did pinouts on various modle of the fuji and deturmined there were 5 pins . the primary is 6 to 8 turns on the outside of these transformers so its easy to find  primary however the secondary has to be ohmed out to determin the three legs.  the secondary is about 1750 turns of fine wire so in that respect they are a bit special for their size.Yes we can and have build many rings and they can be used as well i suspect . If you have that symbol in your schemitic  that would make it a bit easier for replicators . on the lightsaber  pictorial i think the two on one side is primary and the three on the bottom are secondary. Attaches is pinout jesus did a while back.Keep in mind this schemitic is covering only a few of the variations of the camera transformers.
