yup, you never give bad ideas to someone who is crazier than you are (at times even crazier than that!), especially, when they have access to a computer, some software, a table saw, a laser engraver, and a hot glue gun. i took it a little bit farther than expected, and had fun with it. (btw, the I is in the word convent(I)onal). i think there is still room for the optional recalibration tool...
