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!
It’s not a dramatic color shift, but it turns out you can control the hue of EL wire over a narrow range by varying the frequency of the resonating driver circuit. dcroy (upper video) did it back in February using a 555, and Paul Stoffregen (lower video) unknowingly repeated the work recently, having noticed that a single fixed-frequency driver produced slightly different colors in two different lengths of wire.
Milwaukee Makerspace brought electric vehicles and floats to Milwaukee, Wisconsin’s South Shore Frolics parade.

Yes, OK, I know that the weapons in Iron Man’s palms are technically *repulsor* beams, which, at least as I understand them, are a kind of wholly sci-fictional counterpart to the equally sci-fictional “tractor” beam. But this terrifying device from German laserhacker Patrick Priebe, who previously has produced a handheld Nd-YAG pulse laser that will punch holes in, is “working” in the sense that it is a dangerous, if not deadly, directed energy weapon that you can wear on your palm and use to work great evil…
Here’s a fun project to get a walking robot up and running as soon as possible.
Happy International Year of Chemistry! And this is also the 100th anniversary of the award of the Nobel Prize in Chemistry to Marie Curie. To commemorate the occasion, the magazine, Chemical and Engineering News asked several chemists to contribute essays about the achievements of chemistry. Well worth reading is Naomi Pasachoff’s essay on Curie. Truly, has there ever been a scientist as courageous as Madam Curie?
Pleats created in pieces of fabric to create geometric patterns are known as Shadowfolds. Here’s how to fold your own.
Explore the power of microbes with the MudWatt™ Microbial Fuel Cell (MFC) Kit from the Maker Shed. Simply fill this kit with soil from your backyard (or someone else’s backyard), along with any biological matter you find in your refrigerator. Within days the attached LED light will start to blink using only the power produced by the electricity-generating microbes in your soil!
