What kind of gadget can a newbie build using the vast inventory of Akihabara?

I need an easy, yet cool-looking electronics project. In around one month, I'll be visiting Tokyo, including a day-long trip to Akihabara.

Difficulty: I have close to zero experience with electronics. [more inside]

I'm looking for a digital picture frame that can play video and sound. I'd like to find something as close to 15 inches wide as possible. This is going to be used as a part of an exhibit, and must be no wider than 15 inches, total (screen + frame + anything else). There are no specific height requirements. Thank you!

AC/DC for a sub. No, wait...

My son wants to DJ using a conventional amplifier and speakers, but with his car amp (Pioneer GM-D7400M) powering an 800 watt sub-woofer. This requires a 110 volt wall outlet converted to 12 volts. Can he use a battery charger, or does he need a larger, non-pulsing DC source, like an actual battery or DC power supply? Any other options/wiring tips? TIA.
