+ | ====== 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 => [[http:// | ||
+ | * 2 x 75 Ohm resistors 1/4 W => [[http:// | ||
+ | * 1 x USB mini B cable => [[http:// | ||
+ | |||
+ | ==== Schematic ==== | ||
+ | |||
+ | {{: | ||
+ | |||
+ | German Wikipedia-article about the universal serial bus => http:// | ||
+ | |||
+ | ==== 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. | ||
+ | |||
+ | 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 ;) | ||
+ | |||
+ | {{: | ||
+ | |||
+ | ==== Software ==== | ||
+ | |||
+ | When i searched for a good solution to activate the host-mode of the freerunner i found this blog entry | ||
+ | * [[http:// | ||
+ | Joseph Reeves modified his usbmode-button package after a few suggestions by me and here is his new blog-article with Version 0.2 | ||
+ | * [[http:// | ||
+ | |||
+ | Thanks Joseph Reeves :D | ||
+ | |||
+ | You can toggle the host-mode on and off with a click on the icon. | ||
+ | |||

+ | ==== Improvements? | ||
