This mechanical watch shows the moving of the planets around the sun in miniature

Check out this unbelievable watch -- The magnificent Complication Poétique Midnight Planétarium -- which displays a tiny model of the solar system on your wrist. The watch shows representations of Mercury, Venus, Earth, Mars, Jupiter and Saturn. The version without the diamonds will set you back $274,613 in U.S. dollars. The one with diamond is about $366,101!

An article on the watch may be viewed here: http://www.dailymail.co.uk/sciencetech/article-2548017/Forget-smartwatches-wear-150-000-PLANETARIUM-wrist.html#ixzz3VsKzrlM3



To learn more about this fascinating craft, I recommend Watchmaking by George Daniels. The book follows the making of the precision timekeeper, step by step, and is illustrated at each stage with line drawings and brief explanatory captions. The text is easy to follow and to not overly technical.

Gear generator tool allows you to design full gear trains and see them in action!

This new online Gear Generator tool can be used to simulate sets of spur gears. You can plug in all kinds of a parameters, and then animate the gears at various speed to demonstrate working mechanism. You can also download the final results in SVG format. The tool allows you compose full gear layouts with connected gears to design multiple gears system with control of the input/output ratio and rotation speed. The gears are of the involute type which is what most of the world wants -- except perhaps for the clockmakers. This tool is fantastically useful and very well designed too!

Here is where you can check out and use the free online Gear Generator tool.


To learn more about gear design, check out these great reference books such as Dudley's Handbook of Practical Gear Design and Manufacture, which provides comprehensive information on the design and manufacture of gears for the expert and novice alike. Topics include: Gear Types and Nomenclature, Gear Tooth Design, Gear Reactions and Mountings, Gear Vibration, and The Evolution of the Gear Art.

BusyBody - pose and animate a little figure in minutes!

Rufus Seder of Eye Think has just come up with this wonderful animation toy! You pose ten identical bendy figures a little differently in sequence. Then, when you spin the turntable you will see the results animated in the mirror rotating at the center of the toy. What a fun gizmo!

Here is where you can get the BusyBody Quick Pose Animator.


If you are into this type of animation, you might also check out this Praxinoscope available from Amazon. Not unlike the BusyBody, this optical device uses mirrors, paper, and a platform to create moving pictures. When you spin the platform, you can view the animations through the mask plate. It includes printed discs and blank discs for creating your own animation.
