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 ;)


  • 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



  • 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



German Wikipedia-article about the universal serial bus ⇒


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.

  • without the metal part of the connector


  • with the metal part of the connector


  • with hot glue (i know its not very beautiful, but it works, it's robust and i have no short circuit ;)



When i searched for a good solution to activate the host-mode of the freerunner i found this blog entry

Joseph Reeves modified his usbmode-button package after a few suggestions by me and here is his new blog-article with Version 0.2

Thanks Joseph Reeves :D

You can toggle the host-mode on and off with a click on the icon. It works! Fetch4.jpeg Images


Improvements? Ideas!

It works but it's not very beautiful, perhaps you have any ideas. Mail me :D
