I found this crazy tutorial video from Film Riot. They are producing some great DIY content on their You Tube Channel. The video is quite long but if you skip through some of the funny and not so funny stuff there is a cool little DIY Jib Arm to be had. In the video, Ryan states that he would not use this with his camera. I would tend to agree with that statement. However if you are on a budget, this will cost less than a weeks rental for most lightweight jibs out there.
