I've been dying to have a dutch roll effect in ANY production in the future (you know like the scene inside of the oven in Hedwig and the Angry Inch), but those rigs are so expensive that I seriously doubt I could convince a producer it was necessary. So I came up with this fairly simple design to get a similar (all-be-it not as smooth) effect...

Future versions are going to be slightly more complex, I'm just happy enough that the 5dMk2 is light enough to make it work with a drill. Instead of hundreds of thousands, this cost me about 85 cents...

Freakin' genius. Maybe I could do this with my HVX if I used my corded Milwaukee (better torque). And maybe a slightly different build for the back of the HVX.

Thank you sir!

I thought this was a joke when I saw the pic...but I stand corrected. Very cool. Dicy but cool.

Be careful dude you have a lot of money connected to some very cheap screws : )

Yea, it's a first attempt. I've got plans for a more staple design...

Be careful, anyone who might try ths... you don't want to go too fast. But the rolling shutter actually gives you a pretty cool effect when you spin.

Genius! I think I'm going to have to give this a try...

I've always wanted to do those 'blender' shots too, since I saw 'irreversible'...

Nice, I'm going to try this as well

that is awesome. I was hoping to see things like this come soon. I say that because the camera is so awesome yet weighs significantly less then you more conventional HD Cams.

I feel dizzy!

Keep imagining the newspaper headline swirling into view in Spiderman & Superman.

Great effect!

My only concern is the off-center bracket and how you might not get a consistent speed of rotation as there appears to be a bit of weight shift... Or is it the crappy framerate of the vid on my at-work computer?

What if you built a similar designed bracket but it clamped on the sides of the camera with perhaps a sub-bracket that went underneath and a screw into your tripod...hole for additional security? But centering all your mass around the drill head?

Regardless, neat stuff. If a little nausea-inducing. heh. :)

sincerely,

You can always build a steadicam like gimbal around the rotating axis - one hand/"steadyarm" holding it... WOW

If you could balance it around the optical axis it will go on in constant speed I assume but the standard conf is right-heavy and causes some "climb/fall"
