Edison’s Cradle is a bright idea

This interesting take on Newton’s Cradle is called “Asobi” and was created by [Yasutoki Kariya]. However, [Johnny] at Spoon and Tamago dubbed it “Edison’s Cradle”, which we think is a great name.

As you can make out in the video, it isn’t really a Newton’s Cradle. There is a solenoid pushing the bulbs at the end out at the correct time, but that’s fine. The overall result is quite brilliant. Unfortunately, we don’t know much about the setup. Anyone have more information? Anyone want to take a stab at making “Tesla’s cradle”?

Edison clock uses Ammeter plus bulbs to set alarm

This is the Edison clock, designed by [David Krawczyk]. It shows time in the same way as the multimeter clock, regulating power to two analog needle meters. The feature that makes this one a bit different is the alarm. You can see the series of holes on the front of the base. These have a small light bulb socked in each, and correspond to hours and 5-minute increments. Insert two bulbs to set the alarm time, and make sure that the alarm knob points to ‘on’. As you can see above, the alarm has been set to 8:15. Hidden on the last image of the article above is a PDF with just a bit more explanation. Still, much has been left out so if you replicate this clock we want to hear about it.
