How does the 2012 Olympic freefall diving camera work?

 


The "Dive Cam" was done by the great Garett Brown, the inventor of the StediCam. The cool thing with the DiveCam is that is it just a camera triggered by simply letting go of a rope!

When seven-time gold medal winner Michael Phelps slices through the water in the Olympic Games next week, he’ll be followed by a torpedolike underwater HD camera that will capture his every move.

Halloween 2013 skeleton marionette

The goal is pretty obvious this year, but may be a lot more trouble. I'm getting tired of the clunkly, pivoting haunts I always see every year on the DIY blogs as well (as my own lame attempts) and always marveled at the fluidity of puppets. There is something organic and random about a dangling, controlled structure - I just want to know if you can have that visual impact with the constraints of only using a single motor. Yes I could buy several and have  them set for all kinds of whacky phases but I think the single motor limit is what is driving me this year.

DIY R/C Sailboat Project

I've been wanting to combine a few favorite hobbies, woodworking and physics, and dive head first into a project I know nothing about - sailboats. I have been thinking about dusting off the old RC gear and configuring it for small-scale sailing for a long time, so I thought I'd build a boat over the winter. There's something unbelievably rewarding about building something like this from scratch, even more so if you tackle something that you know has a significant probability of failure . This is definitely a boat that is much better built than bought... IF IT WORKS.

 

 

Fixing Toyota power window

 

After my second power rear wind jumped the track on my 2006 Toyota Highlander Hybrid, I decided to document the fix. Hopefully, this helps someone else out because this was a real pain in the ass doing this with little information and avoiding getting screwed but the dealer. I just had this image of some dude/dudette popping off the door panel and whacking something with a rubber mallet for a mere $400.

Rock Tumbler Sound Proof Box

The only drag with this hobby is the sound the tumbler makes for months on end. Its not really a problem for me, as the tumbler is in the shed... but I feel bad for the neighbors. There are tons of articles on sound dampening techniques and Ive tried several, including a plywood box covered with carpet samples. I like the idea of using styrofoam insulation because it easy to work with, has minimal resonance across all audio frequencies, and its non-flamible.

DIY golf Stimpmeter

Make your own stimpmeter

DIY Stimpmeter
I had been playng golf for about twenty years but just began regular putting practice when I joined my first men's club last year. Between the two public courses that I sneak out to for putting practice,  one feels like a shag carpet and the other feels like glass. I've been seeing signs reading   "Current Stimp xx.x feet" for years and decided to build my own Stimpmeter.
