Backpack Portable Xbox Station

After researching the costs of creating a battery system for either the regular xbox or 360, plus a 17" LCD, I have found that it would be too expensive to create a battery based portable system. The DC-DC power supply for the xbox alone would cost ~100, excluding the batteries.

I have revised the project basis for a retractable power cable that would sit inside the backpack. This would also allow for the use of external speakers instead of crappy ones on the lcd panel. Cheap external speakers will either be free or like $10.

Here is the official price list for the parts of the portable xbox station project:
• Used Backpack with bottom compartment to fit xbox – Free if donated, or $30-50 ebay

• Used 15-17” DC LCD w/ speakers - ~$60-80 ebay
• Power strip + Cheap external speakers and audio cable adapter $10
• Retractable power cable 15-25’ long, $40

Not Included in Sale of creation:
• Used Xbox

Total: excluding Xbox console
~$130-190

After we modify the backpack to fit all the parts the xbox console would be easy to switch in and out. At the end of the year we could sell off the modded backpack or raffle it at one of the lans.

Let me know if your interested in helping do this project or have suggestions on the parts used/needed.
