Collaborate Disseminate
Whether you’re a kid or a nerdy adult, you’ll probably agree that the interactive exhibitions at the museum are the best. If you happened to get down to the Oregon …read more Continue reading Interactive Project Teaches Lessons About Electromagnets And Waves
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

Machined from a chunk of a virtually indestructible platinum-iridium alloy, the international prototype kilogram (IPK) was built to last for an eternity. And yet, being the last remaining, physical artifact in a club of fundamental SI units, the current definition of the kilogram has worn out. Most certainly the watt-balance will take its place, and redefine the kilogram with a true, physical phenomenon. [Grady] just built his own watt-balance from scratch, and he provides you with a decent portion of scientific background on the matter.
A watt-balance doesn’t look or operate much different from a regular balance, only instead of …read more

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
