Thats my headphone jack. Theres 3 possbile parts to connect to. Theres these 2 small little hooks on the side, one a little bit bigger than the other, then this huge one that towers over them. This has to be the problem becasue the circuit is just like the diagram.

The large part of the headphone jack (lower terminal in your picture) goes to negative. Choose one of the others and connect that to terminal 1 of the transistor.

Didn't work and I'm kind of pissed Sad
If possible see if you can tell whats wrong or out of place. And I believe thats the way you told me to do the jack.

If you need me to explain my fuzzy picture I can tell you, snce thats as best as i can get right now. Thanks.

The jack looks right, but as for the rest I can't make out where your positive and negative power supply wires enter the circuit and I can't see all of the connection in the fuzzy picture.

Wow, I'm happy to see I'm not the only one who needs additional assistance in doing this type of thing.

Alan, this is what I'm talking about with the color organ instruction. There are people like me who would love to do this but have never worked with this medium before and need a little extra help.

I'm looking for someone to work with me on this stuff.

Also, there was the ieric kid I saw through the comments. He's got a video with wires all stripped and exposed, and he's just asking for trouble with that set up. Did you see the one on his headboard? ugh.

I just threw this together on a proto board before work. I thought I would say that I'm getting better "fidelity" out of the LEDs with a small non-polar capacitor between the pin 1 and 2 of the transistor. It takes a minute or so for the potential to level out before I can see the difference. I'm using a very small ceramic, seems to have about the same effect as a mylar with a little better pickup/response time. It's makes the LEDs a lot flashier I think.

This also seems to have the added benefit of keeping the transistor from sticking open as mine seems to do (very cheap mosfit I guess).
