Do you need a well-equipped lab to measure the size of an atom (German, machine translation )? According to [stoppi], no. You need sunflower oil, some bear moss spores, and a bit of gasoline. You’ll also need some common things like a syringe, a baking sheet, and a jar. You can see the whole process in the video below. The measurement isn’t really for a specific atom, but it is an average for a lipid molecule, which is still impressive. You essentially measure the diameter of an oil drop spread over water. Since the oil is mostly oleic acid, the height of the layer is known as 167 atoms. After that, it is some simple measurements and math to get the height and find the average atom height. The measurement relies on the fact that oleic acid is a lipid and is part hydrophobic and part hydrophilic. This means that when an oleic acid molecule hits water, it stands in a particular orientation. A drop of oil will spread to a single molecular thickness. If you know the volume of oil you ...

In Pirates of the Caribbean , Captain Jack Sparrow has an enchanted compass that points to what the holder wants most in life. The Pizza Compass created by [Joe Grand] is basically the same thing , except it’s powered by a Particle Boron instead of a voodoo spell. Though depending on who’s holding the thing, we imagine they’d even point in the same direction. [Joe] was tasked by Wired to design and produce the Pizza Compass in three weeks, a process which was documented in the video below. Being the Badgelife luminary that he is, the final product looks far more attractive than it has any business being. In addition to the Particle Boron that slots in on the back of the handheld PCB, there’s a GlobalTop PA6H GPS module, a LSM303DLHC compass, and eight NeoPixels that correspond to the points on the silkscreen compass. From prototype to final product. Using the device is simple, just press the button and then walk around trying to keep the top-most LED lit. Behind the scenes, the ...
