Cut the usb cable and seperate the rubber of the usbmini connector and remove the pins 2,3,4 (a lower risk of a short circuit). Now solder the components according to the schematic.

Check the circuit without the metal part, if it works. | Cut the usb cable and seperate the rubber of the usbmini connector and remove the pins 2,3,4 (a lower risk of a short circuit).

USB-Light
One thing that i like on my older phone, a Sony Ericsson W800i, is the light (camera light, but you can use it without the camera). So i thought about a solution for my Freerunner and the result is the following article. At least ⇒ At own's risk ;)
Idea
- Two leds
- Two resitors
- a miniusb B male connector
- a bit solder
- and a bit hot glue
and you have a light for your Freerunner :D
Instructions
Components
- 2 x white LED ultra bright ⇒ LED 3-2000 WS on Reichelt (german distributor for electrical components)
- 2 x 75 Ohm resistors 1/4 W ⇒ 1/4W 75 Ohm resistor on Reichelt
- 1 x USB mini B cable ⇒ AK 673-A USB mini B to normal usb connector on Reichelt
Schematic
German Wikipedia-article about the universal serial bus ⇒ http://de.wikipedia.org/wiki/Universal_Serial_Bus#Farbkodierung_und_Pinouts
Preparation
Cut the usb cable and seperate the rubber of the usbmini connector and remove the pins 2,3,4 (a lower risk of a short circuit). Now solder the components according to the schematic. WARNING ⇒ risk of a short circuit on the metal parts of the connector. Check the circuit without the metal part, if it works.
