LED Guitar

This LED guitar has a 555 circuit that allows the leds to pulse at a desired rate, or stay on all the time.  Its only powered off a 9V battery that i've concealed in the back panel where you would change the strings (so its somewhat easy to change)   This could make for a visual "beat", or strobe when playing.

Step 1:

First i had to make a new front panel for the guitar to hold the extra swiches and POT.

Step 2:

Next i cut out the new piece and cleaned it up.  Also I etched one side to create a fogged effect for the backlighting.

Step 3:

Here is a quick schematic of the design.  Pretty basic 555 timer design, which can be changed for various results.  I put together a small cludge board with each color led on it.  So there are four boards all together for a total of 16 LEDs.

Step 4:

Each color can be turned on independently, or have them all on at the same time.  Combining colors gives you combinations of colors inbetween.
