This build started last year with inspiration from this and other forums. I had all but given up on completion (even offered all this junk up for sale) but finally got it finished.
Sony Effio-E board camera w/ On Screen Display
C mount adapter
75mm lens w/ manual focus and auto iris removed
4" LCD monitor
The problem I have always faced was how to stabilize the lens with the camera mounted in the housing then one day it dawned on me. Mount the lens in the housing and the camera board to the lens!
