Nothing too mind blowing technology wise but I wanted to share my latest project - The RPi 2600. I wanted a portable multi-emulator system I could take anywhere. The result is a RPi B running Chameleon with a cheap 7" TFT monitor mounted inside of an old Atari 2600 "woody" case. For you Atari fans out there, don't worry, everything is totally removable and you can swap the old 2600 board right back in.

The components used in this project are:
RPi B - ($40)
7" TFT - ($34)
(http://www.amazon.com/dp/B007SLDF7O/ref ... 25410_item)
2 Power Adapters ($20 total for 2)
16GB sdcard ($12)
Bluetooth USB ($11)
Atari 2600 ($20 used)
Screws, Hinges, Handle ($5)
Total build cost: $142
(includes everything except controller of your choice)
The RPi B is running the Chameleon multi-emulator (http://chameleon.enging.com/) on a 16GB sdcard. I made a case for it using an old Atari 2600 cartridge "Space War".

The Atari 2600 console case is pretty easy to work with. It only has 4 screws and the motherboard comes out easily in one piece. The only permanent modifications to the case are the 2 hinges in the back and the handle on the front.

The 7" TFT LCD screen is mounted securely via small strips of velcro. It is so light you don't need much and it makes it easy to remove. The RPi cartridge is also attached via a small bit of velcro. To give me more space inside I stuffed the various cords for the screen into a "Combat" Atari cartridge mounted in the console cartridge slot.

To power the screen I had to wire up a 12V DC power adapter since it expects a car battery. So right now there are 2 power cords coming out of the RPi 2600. One plug for the computer and one for the screen. My next project is to make a custom power adaptor to power both and use one plug. I am also looking into battery powered options to make it truly portable.
In terms of controllers I've gotten it working with a Xbox360 wired controller, USB NES controller, and Wiimote via bluetooth. My favorite portable option right now is the Wiimote as it fits in the case and is wireless.

I'm definitely going to continue improving it. As mentioned, I want to consolidate the power supply and look into other power options. I also may build a small amp & speakers into the case for sound. Right now though I'm enjoying it as a practical solution to keep everything together that just happens to look pretty sweet
