Want more details? Well, read what Hackaday has written about my projects so far (not all entries listed):
My cardboard and paper clip CNC, detailed information about rotary encoders and a special encoder made of a resistor wheel are projects with the aim to share base knowledge (a machine is worth nothing if you don't know all details about it).
My first step in upcycling plastic waste was worth a blog entry as well.
Still not enough details? Please feel free to ask your questions in a comment!
