    I used to as well. Had to give it up though. It had a nice sound. I didn't like the high-pitched sopranos as much.

    what would be the best led to use for this project? add an ebay link for some major cool points

    I cant watch the video, so i tried to do it on my own using the schematics that GITRGR8 kindly gave. In a nutshell, I made sure the polarity was correct, and that I used a 100K resistor. I connected the LED to the VCC and GND, and i plugged it in. The second the flash drive connected with my laptop it shut down. What did I do wrong and why cant I watch the video? Could it be that the wires touched the metal casing and shorted it? But why would that cause my CPU to crash? P.S. My laptop is fine.

    Nevermind, i just read that if the USB power jack is shorted out, then most laptops shut down to protect the motherboard otherwise it'd get fried and your computer would die... i am SO glad they put that in otherwise id have a dead laptop.

    Instead of using the 5 volt rail, you could have used one of the data rails. That way the LED would blink when you are transferring data.

    I'm pretty sure if you hooked up an LED over the data rail you'd make the USB drive no longer function (as you are essentially shorting out the rail to ground) You'd have to hook up a small transistor with the LED hooked to power and ground, and then you'd be OK.
