I don't see the laser flickering in time to the music. I've quadruple checked my wiring. When I touch a powered speaker contact to each of the 8 ohm leads on the transformer, I hear music. When I touch a powered speaker contact to each of the outside 1000 ohm leads on the transformer, I hear music. When I touch a powered speaker contact to the banana clips connected to the laser, I hear music. So I know the signal is getting to the laser. I tried shining a light on the solar panel, and I see the voltage increase. But when I turn the laser on (push the button), I don't see any light modulation. When my speaker contact is touching the 1000 ohm transformer leads, or the laser contacts, the music goes away when I turn on the laser, but returns when I turn off the laser. So something about turning the laser on is sinking the modulation?

And also, so powered computer speakers turned up full blast won't be able to amplify the solar signal enough?

Please help! I need this by Friday!

The audio source I'm using is the computer hooked up to the headphones jack. Thanks in advance for helping me!

I also did the receiver test and it does make a noise when I put it up to my CRT monitor. So it must be the laser!

I tried switching the sides on the transformer and that didn't work either.

You need a signal source that can directly drive an 8 ohm speaker.
Add an amplifier to your computer, and use the output that is meant
to drive a speaker.
