I suspect tho, that manually wiring 306 leds for charliplexing is gonna be quite a pain in the ass.
I would have rather multiplexed them using shift registers and preassembled 8x8 led matrices.
I've a friend who actually manually built a 16x16 led array and I can tell that after placing and soldering 200 of those, he wasn't that excited about the project anymore.
But if you still do it, that would be cool, I fully support you![/quote]

Thanks for the advice. I cannot really use 8x8 because my LED's are placed in a horizontal line. What I will be using is 1/4 inch adhesive conductive http://www.stewmac.com/shop/Electronics,_pickups/Supplies:_Shielding/Conductive_Copper_Tape.html copper tape which I already bought and works great. I haven't got yet the best idea to join the copper with the LED's, which will be a big pain in the ass but I dont really care spending time doing it. I can't solder (and dont want to) because I am working on top of a photo and I dont want to burn it. I've been thinking about using a solder pen or some conductive glue. Any suggestions? I might leave the wiring exposed so I want it to look nice. thishttp://www.flickr.com/photos/62145351@N00/2768386897/sizes/o/ is a photo of the beginning of the schematics, for anyone interested.
