The GraviComp Gravity-Powered Mechanical Computer on Channel 9

The “Channel 9” Web site is an interesting Microsoft site that publishes all kinds of videos. Nick Landry, a colleague of mine at Microsoft (I don’t work directly with Nick but he’s a frequent speaker at software conferences like I am), created a series of videos called the Maker Show. The videos showcase hackathon-like projects built by Microsoft employees.


Several months ago, I built a very large (12 feet high by 4 feet wide) gravity-powered mechanical computer. I call it GraviComp. Nick took an old 4-minute video of GraviComp that I recorded, spiffed it up a bit, and posted the video on Channel 9. See


One of the best things about working at Microsoft is the people — there are some really bright and creative people everywhere at Microsoft. Also, management is, as a general rule, very supportive of creative activities (as long as they complement “real” work in some way).

    Would you have some pointers or more detailed design to share?

    Btw, the youtube video “Mechanical Computer (All Parts) – Basic Mechanisms In Fire Control Computer” which you shared in the Channel 9 video description was pretty awesome. Thanks!
