Filed under Kippycam

I had the wireless router to show the webcam images for the 'kippycam'. Some discussions in the openwrt forms showed, that there are several spare GPIO pins on its chip. So: there is a chance to do all kinds of hardware control. This rekindled some childhood enthusiasm for electronics that I had nearly forgotten. So, how did I add hardware control (specifically, the I2C interface) to the TL-WR703N?
