This instructables project details the latest version of the bicycle mounted steadicam arm (constructed from hardware store and hobby shop parts) for a miniDV camera. I've used the video that I've captured to create DVDs for: a bicycle shop and for myself (as motivation for my indoor biking). The original article is titled: DIY: Bicycle - Steady Cam - mount
The last version of the steadicam arm (from the previous project) looked like the image you see below. This version had two iso-elastic arms operating in different directions. One for up and down movement and the other one for side to side movement. However the need for the side to side arm wasn't as bad as the need for additional compensation in the up and down direction. In the new version I rotated the arm (shown directly under the camera) such that it provides isolation in the same direction as the first section (see second picture in this step).
