It looks like you're shorting the LED. it looks like the bare wires are touching the copper heatsink.

The wires were touching, and that's been corrected now, thanks Phoenix.
Unfortunately I'm still getting no sound or lights. My gut is telling me I've got the wrong transistor (But my confidence has been shot with this project, and could be anything). I'm using a NTE 2542 transistor. Here's the info I have on it. (I can't make heads or tails of it)

Note 1. For NTE2542, the polarity is reversed.
Some may leave The Jedi Order; but few leave it alone.
If the red and black wires going to your recharge port are red for positive and black for negative, you have it wrong.
