Awesome cube, Eliten, and sweet shirt, Ish.
Picture dump, woo. Since I took the top half off the DS there were no more speakers and no more Wifi. So, I took out the stylus holder to make room for a mono speaker and wifi antenna.
I didn't have to drill any holes for the speaker because the hole for the stylus lets out adequate amounts of sound.
The resistor and speaker wires soldered where the screen's ribbon cable connector used to be:
Last night I also made a light for my Kindle. It consists of an LED backlight and driver circuit I took out of a portable DVD player screen and a GBASP battery to power it.
Charging: (I didn't add a charge port, I just connect alligator clips to charge it.)
This photo was actually taken in daylight, but the light is so bright my camera had to auto-adjust.
The driver board has three input pins: Vcc, GND, and brightness adjust. I hooked up that pot on the right as a voltage divider, set the brightness so the whole thing drew 50mA, and glued it down. At 50mA it puts out a lot of light and since the GBASP battery is 600mAh it should last quite a while before needing a recharge.
And for no reason, one of the screensavers I put on.
