I've spent most of this year's (2014) summer learning how to use a CMOS sensor together with an arduino (ATmega328p) microcontroller, in the process of developing some personal projects.
This is the first of a series of articles to publish my experiencies, and hopefully save someone's time.
In this first post, I'll just release the minimal info that may let you start right away experimenting without reading about how things work. In further articles I'll make detailed explanations of the hardware and software, and the decisions and reasons that led me to my current setup. However, at the end of this post, you may find links to useful documentation.
I've spent last month struggling (once again, after some trouble with the power) with SD card corruptions due to the Raspberry Pi's "design idiosyncrasy" (a funny name to avoid cursing). Until I finally found a solution...
Today I collected my first microfused things from Fundiart, in Valencia.
The items were printed in PLA and cast in brass, and the results are excellent.

So, here we are again, with Climberbot II, of the babelbots project. Last
version was made out of recycled scrap and household stuff. And it
worked, partially. But the tracks were not good enough for further
