Excellent website, I too have just discovered it, a simple easy to understand and practical approach to a technological subject. My 9 year old son was amazed by the CNC mill using everyday components so much so that he has pressured me into building it.
Thank you for sharing.

Me: Thanks for all the good words. Would be nice to see your son's CNC soon.

Excellent site just dicovered it and i am hooked.
Love your teachings as well as how simple you make it attracts the novice without making them fearful.
Using cheap materials to build the cnc is a real plus to understand the concept research it without expending an arm and a leg.

Thanks Norbert have a great half life

Me: Thanks! The working principle of the photo sensors and the DC motors is explained in more detail in the chapter about the Arduino Uno.
