DIY science is the perfect way to use your creative skills and learn something new. With the right supplies, some determination, and a curious mind, you can create amazing experiments that open up a whole world of possibilities. At home-made laboratories or tech workshops, makers from all backgrounds can explore new ideas by finding ways to study their environment in novel ways – allowing them to make breathtaking discoveries!
Becky spotted this “kodachrome curtain” from Flickr user yarnzombie in her weekly CRAFT Flickr pool round-up post. Besides the coolness of the idea itself, this is a great example of the power of a good photograph to sell your project. Gorgeous shot!
Happy Birthday Gallileo Galilei! Galileo Galilei (15 February 1564 – 8 January 1642) was an Italian physicist, mathematician, astronomer, and philosopher who played a major role in the Scientific Revolution. His achievements include improvements to the telescope and consequent astronomical observations, and support for Copernicanism.
ur very own inimitable Becky Stern makes and sells these beautiful custom scarves featuring the atomic emission spectrum of your favorite element. Shown above is the “silicon” version (as modeled by AdaFruit’s likewise inimitable Limor Fried) but you can choose whichever element/spectrum you like. And here’s a handy-dandy Java applet from The University of Oregon that makes it easy to browse for your selection. Minimalists may prefer hydrogen or helium, but for my money it’s hard to pass up the rainbow-y goodness of, say, iron or tantalum. Want!
Yes, this is a missile. Sorry about that. But it turns out the AIM-9 Sidewinder is the only well-documented example I can find, on the web, of a machine that employs these interesting little widgets called “rollerons.” See the little metal pinwheels at the trailing corners of the fins? The rolleron is basically an air-driven gyroscope, as Tom Harris explains over on How Stuff Works:
In these photos, you can see the heat transfer happening through a number of roofs in my neighborhood. In a wintery time like we have now, the snow acts as an indicator of your insulation. If you have a full roof of snow, then you’re well insulated. If you have spots of bare roof surrounded by snow, then inside the house is an area where it’s uninsulated, or poorly insulated. If your roof doesn’t hold the snow at all, then it’s time to look at your attic insulation. Sunny, South facing roofs will naturally clear faster on clear days, due to the input of solar energy.
Sean Ragan shows you how to use the label on a beer or wine bottle as a built-in resist for etching on the glass.
Astronaut Bob Behnken participates in a spacewalk during STS-123. Image courtesy of NASA. Imagine having your workshop traveling at 17,500 miles per hour more than 200 miles over the Earth as you work through grueling, painstakingly-planned out steps of a project with specialized gadgets like a massive Pistol Grip Tool. STS-130 mission specialists, Bob Behnken […]
