Maybe you've heard music. But have you SEEN music?
The Muzak Visualizer was designed by me, nmcclana. It's based on the open source Pixelmusic project with a few modifications to enhance the visuals and do the ADC on the Propeller. NOTE: This project has been updated to reflect Gadget Gangster's new project boards. The project boards in the photos are yellow because they're prototypes, but the final boards have a soldermask.
You can get the kit from Gadget Gangster. It comes with everything and is pre-programmed. But, if you'd like to gather the parts yourself, you'll need the following.
Here's a little video demonstration

Parts list
- Resistors, 1 each of : 1.1K, 270, 560. 2 x 10K
- 2x RCA phono jacks (1 for the Video out, 1 for the Audio in)
- Gadget Gangster project board (Boss Board)
- 8 Pin Dip Socket
- A 3.3V LDO Voltage Regulator (Kits come with a LD1117)
- Power Connector
- 40 Pin DIP Socket
- Parallax Propeller
- 5MHz crystal
- .1uF Capacitor
- And a programmed 32KB i2c EEPROM. You can get the Source Code off Gadget Gangster

You're going to be adding the main power for your project. To get started, let your soldering iron warm up and put the Boss Board in the vise.
The main voltage regulator goes at the part of the board labeled [Pc].
The regulator is inserted as shown in the picture. Note how the tab lines up with the square of bare metal. Use a bit of solder to 'tack' down the tab to the board, this will act to dissipate heat. Once the regulator is inserted, flip over the board, solder the legs to the board and trim the excess lead.

Do you have an actual schematic so I can try this on a breadboard?

I don't, but the software is based on a <a rel="nofollow" href="http://makezine.com/14/pixelmusic/">pixelmusic</a>, and they have a schematic. Their design is a bit different, though, as they decided to do the ADC off the prop.<br/>
