Both Explanation And Build For This Artwork Are Beautiful

Posted on by

Sometimes you encounter projects that defy description, as is the case with this one. So perhaps it’s best to start with what this project is NOT. It is not a sphere. It is not a perpetual energy device. It has neither a sloppy build nor a slapdash video. This IS a motorized rhombicuboctahedron that is a well-explained with high-quality parts and loving attention to detail by [Wolfram Glatthar]. At its heart is an exercise in building a moving device with the barest minimum of friction. Without no grinding in the mechanism, the electronics will probably wear out first. Low friction …read more

You May Have a Nixie Tube Clock, but Can Yours Levitate?

Posted on by

nixie tubes, electromagnets, levitation, and microcontrollers, this project has “Hackaday” written all over it!

Time Flies: Levitating Nixie Clock comes from [Tony Adams], and uses a lot of technology we’ve seen before, but in a new and interesting way. A nixie tube clock is nothing new, but using electromagnets to levitate it above a base certainly paired with inductive coupling to transmit power using no wires make this floating nixie build a real treat.

In order to achieve this feat, [Tony] used coils to wireless transmit power from the base to the floating platform that the tubes are mounted to. …read more
