Video Youtube

I've just signed up a Youtube account (ZDP189HK) to share videos. I'm not competing with Jörg; I'll just post maker tutorials and technical videos there.

Here are three videos to kick off. They were shot in high speed motion capture to illustrate and measure slingshot action and band acceleration.

This is one of Perry's with natural rubber bands filmed at 420 frames per second.
