We see a lot of clocks here at Hackaday, so many now that it’s hard to surprise us. After all, there are only so many ways to divide the day …read more Continue reading Displaying the Time is Elemental With This Periodic Table Clock
One of the nice things about the Internet is that you don’t need huge reference books anymore. You really don’t need big wall charts, either. A case in point: what …read more Continue reading Google’s Periodic Table
It wouldn’t be much of a stretch to say that here at Hackaday, we’re about as geeky as they come. Having said that, even we were surprised to hear that there are people out there who collect elements. Far be it from us to knock how anyone else wishes to fill their days, but telling somebody at a party that you collect chemical elements is like one step up from saying you’ve got a mold and fungus collection at home. Even then, at least a completed mold and fungus collection won’t be radioactive.
But if you’re going to spend …read more

Most people obtain a bachelor’s degree before getting their masters, and even that is a prerequisite for a doctorate. Most people, however, don’t discover a new chemical element.
Marguerite Perey graduated with a chemistry diploma from Paris’ Technical School of Women’s Education in 1929, and applied for work at the Curie Institute, at the time one of the leading chemistry and physics labs in the world. She was hired, and put to work cataloging and preparing samples of the element actinium. This element had been discovered thirty years before by a chemist who had also been working in the Curie …read more

Looking at the ingredient list of some popular processed foods will produce a puzzled look on the typical hacker’s face. Tricalcium phosphate, thiamine mononitrate, zinc proteinate, pyridoxine hydrocloride… just who the hell comes up with these names anyway? It turns out that there is a method to the madness of chemical name structures. Some of them are well known, such as sodium chloride (NaCl) and hydrogen peroxide (H2O2). Others… not so much. In the early years of chemistry, chemical substances were named after their appearance, affects and uses. Baking soda, laughing gas and formic acid (formic is Latin for …read more
It seems like every other day we hear about some hacker, tinkerer, maker, coder or one of the many other Do-It-Yourself engineer types getting their hands into a complex field once reserved to only a select few. Costs have come down, enabling common everyday folks to equip themselves with 3D printers, laser cutters, CNC mills and a host of other once very expensive pieces of equipment. Getting PCB boards made is literally dirt cheap, and there are more inexpensive Linux single board computers than we can keep track of these days. Combining the lowering hardware costs with the ever increasing …read more
They didn’t teach you this in high school physics. Continue reading Will the Periodic Table Ever Be Complete?
