DIY hand-cranked geared string winding machine

video
One dedicated reader of The Autoamta / Automaton Blog made this cool prototype string-winder contraption. It makes a center-pull ball of string with a diamond pattern. To generate the gear profiles, he used Matthias Wandel's Gear Template Generator.

Here is a nice schematic drawing of the device followed by an explanation.
DIY hand-cranked string winding machine

From bhaaluu's description:

The hand-crank turns a 30-tooth peg-wheel gear which drives a 10-tooth peg wheel gear. The 10-tooth peg-wheel gear spins on a fixed vertical shaft. connected via a wooden tube to the spindle head, which rotates at a 3:1 ratio. At the top of the fixed vertical shaft is a 15-tooth spur gear. It is fixed to the vertical shaft and doesn't move. At the base of the spindle tube is a 42-tooth spur gear which rotates on it's own axis, which is tilted at an angle. As the spindle tube rotates around the vertical shaft, the 42-tooth spur gear rotates. The spindle tube, a heavy-walled cardboard tube, is connected to the 42-tooth spur gear, so every time it turns around the fixed vertical shaft, it rotates. This is what gives the diamond pattern. This string winding contraption is a prototype.

Leonardo's Machines: Da Vinci's Inventions Revealed

Leonardo's Machines: Da Vinci's Inventions Revealed
Here is a highly-rated book that explores Leonardo's inventions from flying, hydraulic, war, and theatrical machines to musical instruments. This uses Leonardo's orginal artwork and annotated computer diagrams to show how each of his inventions might would have worked.

It seems to be out-of-print, but can be found used at Amazon. Here's a link to Leonardo's Machines: Da Vinci's Inventions Revealed

Make this charmingly disagreeable machine

Check out this wonderful little motorized contraption that simple does NOT want to be on.

If you are inclined to make one, or learn more about it, there is a full instructable on how to build what they call "The Most Useless Machine EVER!". (I don't agree with the name of the device; entertainment and laughter are far from useless.)

Huge house-wide Rube Goldberg contraption

Huge house-wide Rube Goldberg contraption
I'm not sure if this video has been kicking around the internet for a while or not, but it's new to me. These ingenious folks have created a Rube Goldberg machine made out of familiar household items, clothing, dishware, string, CDs, and lots of black duct tape. My favorite section is the chess game sequence. Brilliant!

Here is a link to video of the Rube Goldberg contraption on the Baynham & Tyers web site.

Three spherical 3D ball maze puzzles

Check this assemblage of 3D puzzles. With all three puzzles the idea is to rotate the sphere such that gravity pulls the small enclosed ball through loops, tracks, corners, walls, and around the various pitfalls of the 3 dimension maze. They look pretty challenging/fun to me.

The Time Machine table top rolling marble clock

The Time Machine table top rolling marble clock
The Time Machine is a mechanical tabletop clock that moves a set of chrome balls every sixty seconds. There is a track of accumulated balls to indicate the hour of the day and another to indicate the minutes. There is a even a second hand on top.

It comes with a custom acrylic display case that makes it look really retro-future cool (not shown here). Reports are that this thing is captivating. One note: because of the constant clacking of the chrome balls this isn't a clock you'll want to put in a library.

Here's the link for more info on the Time Machine Tabletop Clock
