"Serpina" -- an electromechanical wooden rolling ball clock by Christopher Blasius

Christopher Blasius wrote to let us know about his latest creation: an electromechanical wooden rolling ball clock. Check it out!

From the creator:

I have designed a new clock. Her name is "Serpina" and it's a electromechanical rolling ball clock. Instead of a pendulum, a ball rolls down an inclined plane, which takes 20 seconds. Then the seesaw then tips in the opposite direction and the process begins again.

Free plans for a charming cat and mouse autoamton by Christopher Blasius

Check out this really nicely made video showing step-by-step how to make a cat and mouse automaton. The narration is in German, but the video is so clear it hardly seems to matter. (Incidentally, if you turn on the YouTube CC function, English subtitles are shown.) This charming automaton was created by Christopher Blasius.

You can download free plans for the cat and mouse automaton from his web site.

[ Thanks Charles! ]
