I finished the machine, it still has a few rough point, but I you'd like yo see, follow the link below. http://basdebruijn.com/2014/05/additive-wire-laying/ >> >> Currently I have enameled wire, but I would rather use clean copper. >> My thought is that inserting components after the wire has been made >> (cut with a piece still standing out (hovering) above a recess), will >> bend the wire down (in a recess) like forming a sheet metal plate. >> Then turn around and apply a little solder.

I will make a base, with a recess/holes, and find out what the dimensions need to be. > > -- > Charles Steinkuehler > char...@steinkuehler.net > > ------------------------------------------------------------------------------ > "Accelerate Dev Cycles with Automated Cross-Browser Testing - For FREE > Instantly run your Selenium tests across 300+ browser/OS combos. > Get unparalleled scalability from the best Selenium testing platform available > Simple to use.
