$20 SteadyCam in an afternoon

Heres a cheap and easy steadycam which works amazingly well. The design is based off Johnny Lee's, which can be found at http://johnnylee.net/. More of my projects can be found at patricksprojects.posterous.com or here on instructables.
Very nice. I do have one question: It appears as if the two vertical pieces of pipe were the same length, or they were equal distance from the fulcrum (or 'T-joint'), so in this case you weren't actually getting a 'geometric' advantage. Shouldn't one of the pipes have been either shorter or longer than the others to take advantage of the 'geometry', or did I miss something?
That's correct - the T-joint is in the middle, but that's not the fulcrum. I guess I didn't make that clear in the instructable. The handle is only for stabilising it from twisting left to right (z-axis if using NED coordinates). Your hand other hand is the fulcrum for the x- and y-axes, and that should be holding the pipe close to the camera
How do you attach the camera and what purpose does the concave washer serve?
Good questions!<br><br>The screw coming out the top is a 1/4&quot; Whitworth, which is the standard for camera tripods. Almost any camera that has a tripod screw mount will fit that.<br><br>The concave washer spreads the load out across the base of the camera so that there isn't a concentrated load on at the attachment point. For my point and shoot it's not so much of a problem, but for larger cameras you really don't want to have its whole weight focused on one small 1/4&quot; point
Nice concise yet complete video. I like the physics explanation at the beginning and being upfront about your inspiration.
Oh good, I was afraid the physics might bore people too much. Thanks! Always good to know I'm on the right track
