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!
The amazing Vi Hart (daughter of our Math Monday columnist George Hart) has blown our minds again with this over 12 minute video explaining the math, science, and art behind sound. In many of Vi’s videos, she talks really fast, and it’s a style that works for her, but for something this info-dense, with lots of visual aids, it’s worth going through a few times to absorb everything.
Tyto Alba is an art car made from the remnants of 25 bicycles, along with an owl figurehead fashioned from leather feathers. Brother John and Sister Sharon combine their skills of mechanical engineering and leather shoemaking to showcase their creation at Maker Faire Bay Area 2011.
A mathematical haircut makes an unambiguous statement to the world that you love math. Here, Nick Sayers is sporting a rhombic coiffure with interesting geometric properties.
Unless your application is critical, cheap liquid paint stripper from the hardware store (not the gel, paste, or color-changing varieties) is a fine substitute for commercial acrylic solvent cement. Comparing one MSDS to another, we see that each product is about 75 wt% dichloromethane (AKA methylene chloride), which is the “active ingredient” that softens the plastic and allows it to weld. Purpose-made acrylic solvent is a bit thinner, in my experience, and evaporates a little faster, and contains trace amounts of acrylic monomer that may result in a slightly stronger bond, but for most practical purposes I have not found these qualities to justify paying twice as much for it.
Whenever there’s an available surplus of watch parts it seems that makers tend to gravitate toward constructing vehicular creations: motorcycles, mopeds, etc. We’ve covered these kinds of slick, brassy machines in the past, and Blogger user 2nde VIE (2nd Life) follows where other such makers left off, but then veers into creature territory. He uses the discarded parts to make clockwork owls, turtles, and other entities that have a whimsy that’s all their own. [via Recyclart]
This is a piece of free-burning ABS tubing showing characteristic flame color and smoke. The burn test, as itโs known, correlates a plastic sampleโs composition with a set of observable properties includingโฆ
As much as I enjoyed this unusual technical info from GeekDad contributor Roy Wood, I was disappointed to learn that not all 18,650 things you can do with an old laptop battery are specifically listed in the article. Moreover, by a truly amazing coincidence, “18650” turns out to be the part number for the most common size lithium-ion cell used in assembling laptop batteries.
