Just a few weeks ago, I posted something called the HandiZoom that aimed to provide a handheld electronic zoom for DSLR lenses. The problem most people saw was that when shooting DSLR video, the lenses don't Auto Focus (at least for Canon) so as you zoom in, you'll need to chase focus. YouTube member madboardfun decided to solve that problem by taking a Nintendo Wii controller and making a DIY arduino based electric Focus & Zoom that can be programmed to synchronize the focus point. Basically it stays focused on the subject while it automatically zooms in. Very cool DIY project. [Thanks Guy]
