How To: Wildlife Photography with a DIY Motion-Triggered Camera

Even if you live in a big city, chances are you have some wild raccoons or foxes that cannot abide a vertical trash barrel. While apparently omnipresent, these phantasmic critters usually vanish in the night leaving only a shameless trail of refuse you never wanted to see ever again. While I haven't found a way to stop them, I can help you snap some photos of the dastardly creatures.

News: Pure Silicone Casting

For those of you who enjoyed the oogoo tutorial we did, this tutorial from instructables shows you how to make molds from 100% silicone gel for casting resin! I wonder if you could also cast other silicone shapes using a silicone mold...

News: Make Insulating Glass Conductive with a Blowtorch!

Have a few light bulbs and a blowtorch? Then join the folks over at Harvard in a cool science experiment on the conductivity of glass. As you well know, glass is an insulator with low conductivity and high resistivity. In the video below, they flip the switch, demonstrating how heating the glass fuse enclosure from an incandescent light bulb can create a conductive material that completes the series circuit and lights the second light bulb. In the video, the two light sockets are wired in ser...

News: Medical Intestinal Camera Teardown

Mike received a tiny medical pill-camera from a relative who had recently undergone treatment. The most surprising part apart from the utter grossness is that the camera transmits electrical signals straight through the human body to skin electrodes with no radio at all! Check out the video to see the camera and Mike's impressive mastery of the oscilloscope.

How To: This DIY Soft-Circuit Military Tech Lets You Power Electronics Using Your Clothes

It turns out that the popularity of soft circuit electronics has leaked out of the interwebs and into the hands of the U.S. military. Soft circuit electronics allow you to literally sew electronics circuits into fabric using flexible conductive thread instead of wire. Soft circuits can be used for all sorts of fun projects, like the TV-B-Gone Hoodie and the Heartbeat Headband.

News: Explosive Polymerization Is Basically Magic

This video is by Adrian McLaughlin, aka plasticraincoat1 on YouTube, who shows us one of the most magnificent examples of explosive polymerization ever. In the video, what appears to be about 1/2 tsp of p-nitroaniline (which is short for para-nitroaniline, which is also referred to as 4-nitroaniline) is treated with a few drops of concentrated sulfuric acid, in a ceramic dish, over a Bunsen burner flame.

How To: How This Newly Discovered Amazonian Bacteria Is the Secret Key to Biodegrading Plastic

Since the rise of private property and industrial production, modern capitalism has been on a undeniable crash course with Mother Nature. It's no so much that we'll end up murdering the entire planet, but just that the planet will quietly smother us with a pillow of famine, heat, cold and hurricanes. We over-farm land and replace the nutrients in the soil with oil. To package our oil-based produce, we wrap them in synthetic oil-based plastics, soon to be discarded in a trash heap or ocean.

Red Wine: The Secret to Superconductivity

We've all heard of the power that red wine holds. It can help lower risks of heart disease, boost your brain power, and can even recharge your car battery. But last year, a group of Japanese physicists made headlines when they announced that they could induce superconductivity by soaking metals in red wine. But why red wine?

Arduino Air Force: DIY Robotic Cardboard Quadcopters

You're hellbent on taking over the world, but one race of robotic minions isn't enough for you. With your hexapod robots acting as your ground forces, it's only natural to take to the skies. These cardboard quadcopters are the perfect air force for you. Combined, you are mere steps away from starting your evil takeover. Now you just need some water bots. The cardboard flying quadcopters are built around the MultiWii platform with the twin power of Processing and Arduino, so they are actually ...

How To: Make Your Very Own Blinding Sunbeam with a Lithium AA Battery

Taking apart batteries is one of those things that every adult you've ever known has warned you against. Today, we break the taboo and dive into a lithium battery. Lithium has some pretty cool properties—it burns instantly in water and glows blindly bright under flame. And with just one AA battery, you can make a blinding light beam inspiring supernatural awe in all dictatorial adults who doubted you.

Force Lightning: How to Make a Shocking Cookie Jar Any Sith Lord Would Be Proud Of

There is nothing more annoying than a greedy roommate. It's absolutely infuriating to wake up and find the cookies your mother just made for you gone without a trace. Your favorite drink is empty and the homemade meal you worked so hard on the night before is nowhere to be found. This irked me so much that I made this shocking cookie jar. When a cookie burglar touches the side and the lid of the jar simultaneously, a small electric shock stops them in their tracks.

News: This DIY Mini Tesla Coil Packs 380,000 Volts of Lightning

At one point in time, Tesla coils were actually used for things like wireless telegraphy and electrotherapy, but as technology advanced, they shifted to a slightly more enjoyable purpose—entertainment. What's even more entertaining than using a Tesla coil? Building your own. One of the best portable Tesla coils out there is this mini acrylic version by Daniel Eindhoven, aka TeslaCommander. It's made almost entirely of acrylic plastic, minus the steel sphere, and copper wire and tubing. When t...
