I recently upgraded to an SLR with video which I think is the greatest thing ever! However the traditional techniques embedded in me to hold my camera don't work with video. It's way to shaky but there are solutions out there but they aren't cheap. I chose to do more of a gun style just for the ease of creating and I am very happy with the end result. Also the cheap versions you would buy don't have focus and shutter buttons in the handle.
Step 1: Materials
I started out with 3/4" PVC from Home Depot. It is super cheap and easy to work with. I bought two small sections for 1.15 or so each then 3 elbows and 1 T. I purchased 2 buttons from radioshack for a few bucks and I had the phone headset laying around. *I had an adapter from 3.5" to 2.5" from a gaming head set you don't need to do this step if you already have the smaller 2.5" and you want to just run that cable out*. You'll need some random wire from the old junk drawer and some solder/tape.
Step 2: Laying Pipe
The longer peices are 8.5" and the shorter are 6.5" on mine but I would encourage customizing it so that yours will fit you better. I had 2 of the 8.5" and 4 of the 6.5"
Step 3: Custom Head
I had a piece laying around from an old school flash bracket so I cheated a bit and used that. However I did make up a little schematic to supplement with a piece of wood or plexi-glass. Cut a notch in the end of the pipe and drill 2 screw holes. Then fasten the plate to the pipe. Make a handle with tripod thread by putting a tripod thread sized bolt through a cap and attach it to a 6.5" piece of pipe and drill a hole into the plate and viola.
