Plug in this internet radio player and listen to your favorite stations on Pandora Radio. Six pushbuttons control the music, while an LCD gives feedback on the song, artist, and other useful information. All of this is housed in a custom acrylic case with access to the Raspberry Pi's ports.
Special thanks to LVL1 Hackerspace (www.lvl1.org) for use of their laser cutter!

Step 1: Parts List
In order to build the system, you will need several things. The main piece is a Raspberry Pi Model B with a 5V, 1A power supply. This Instructable is based on a Revision 2 board, but will work on earlier boards with minimal changes.
Next, you will need an SD card with a Raspbian Wheezy image. Instructions for this process found at: http://elinux.org/RPi_Easy_SD_Card_Setup
Electrical hardware needed:
1) Solderless breadboard (and wire)
2) Serial LCD module (3.3V module from Sparkfun was used: www.sparkfun.com/products/9067)
3) Ethernet Cable
4) USB Keyboard and mouse (necessary for setup, not the final product)
5) Pushbuttons (6) - "Normally Open" type with threaded mounts
6) 3.3V Regulator (LM1117T-3.3 from Texas Instruments in the TO-220 package type used here)
7) Resistors: (7) ~10kOhm, (6) 1 kOhm
8) Capacitors: (2) 10 uF tantalum (as recommended by TI for 3.3V regulator
9) Pi T-Cobbler from Adafruit (not necessary, but makes GPIO access much easier)
10) Auxiliary audio cable
Other equipment needed:
1) Soldering Iron and solder (for the T-Cobbler breakout board)
2) 1-Minute Epoxy (for the acrylic case)
3) Acrylic (and a means of cutting it)
4) Nylon Standoffs and Screws
5) Velcro strips (with sticky sides)
The acrylic used in this project was 0.08" thick and can be found at Lowe's in 8"x10" sheets. This was great for cutting with a laser-cutter. Other thicknesses can probably be used - this will be left up to your discretion (and experience).
The standoffs used were a combination of (3/8" - hex - 1.25" - 4-40 thread) and (3/8" - hex - 0.375" - 4-40 thread) nylon male/female standoffs. 4-40 fillister flat head nylon screws were used with these standoffs.
Although this Instructable includes directions for the custom case, this is probably the trickiest part of the design. Familiarity with a laser-cutter is necessary, since every laser cutter and design software package is different.
