[Gmecm] ECM test bench

[rawardsr]

Apparantly you haven't looked at how much pots, connectors, and switches 
cost.  Good luck assembling all the bits (quality stuff) for less.

Let alone the cost for a low production board run.. hehe.

First I've heard about that, and I'd look to the code first. Not is all 
that is seems.  Bob

Although I wouldn't mind taking a look at his design to have a starting point.  Ideally I'd like to see the cost get down to $100 with parts and board.  How realistic that is is yet to be seen.  I'm getting a preliminary budget together as we speak.  Cross your fingers ;)
