Coupler for Gopro Hero 3 to Brunton Echo monocular = airsoft scope-cam by RandyR

Last crawled date: 4 years, 1 month ago

I am trying to devise and build a "scope-cam" for airsoft use... a camera that mounts to the airsoft gun and mimics the view through a scope. Since I had a Gopro Hero 3 handy, I thought I'd try to couple it with a Brunton Echo 7x pocket monocular that I also had on hand. This is a simple coupler to connect the two together, though it requires unscrewing the eyepiece lens from the Brunton Echo first.
I apologize for not having more pictures of the result, but I managed to break my Brunton echo on an early prototype that was a little too tight a fit. The uploaded design has been made a little looser, but I haven't been able to try it yet. If you give it a go, let me know how it works.
