U87 clone -> https://www.youtube.com/watch?v=DtNH46jpwJo&noredirect=1

@Gregg 
UMMM... AWESOME!!!! I would like that too, but I'm going to start with a u87 clone, then try and build a shotgun / hypercardiod with a 3d printer.  

Also, ADC building... I want to start simple with an arduino-based ADC

Let me know if you guys are into the first project for the u87 clone.
