Inexpensive MSO

A friend pointed out this inexpensive MSO.  $250 for a lot of capability.  Looks like it’d be great for a home lab, or even for light professional work.

Camera Mounts & Stabilizers

Dan asked if I could help him build a series of camera mounts and stabilizers so he could capture video for paintball and canoe jousting.  We started out building a simple clamping mount for a waterproof digital camera, intended to be used on canoes to get shots of the paddlers, and of the boats capsizing.  ...
