Here's a little demo video of the Jukebox in action. I customized the look a little from the options menu in SK jukebox (Press 'O' for the Shortcut). I chose to display the selection menu in the lower right and changed a few of the Fonts and Colors to suite my fancy :)
I recently modded my PSP with a clear case and [6] 0603 surface mount LEDs. I added a tilt switch for the front most [Blue] LEDs so i could turn them off quickly (and save battery life) if i wanted by just tilting the PSP back. I also found that blue LEDs need a 3.0 - 3.6V forward voltage to light up so i had to wire them directly to the battery with the Tilt switch in series (Just under 4V). The other Red and Orange LEDs opperated fine wired to the ON switch which is approx. 2.2V on my PSP. They are always on when i turn on the power. It's nice to be able to turn the front LEDs off when i'm playing due to the bright annoyance factor.
Oh yes and i wanted to comment that this idea was not my own, it was from a Tutorial @ Llamma.com check out the following link if you'd like to do it yourself: www.llamma.com/PSP/psp_led_lighted_trigger_buttons.htm I added a tilt switch for my own preference.
The supplies i needed to build this Touchscreen Digital jukebox were:
a touchscreen from eBay's Dr. Touchscreen
Carbon fibre printed peg board from Totem Building supplies
LED Arcade Buttons from ebay
a Coffee table i found at the thrift store for $4.
Free Keyboard from work (sticky buttons)
Jukebox Software
I used free Software from Salmon King called SK Jukebox, although there might software out there that may look more pleasing to the eye SK jukebox is definitley the most bang for your buck. Download the software from here:mirrors.arcadecontrols.com/Salmonking/
