DIY Lab Equipment: Make an Etch Tank for Rapid PCB Fabrication
I love making my own printed circuit boards. It really gives a professional look to a finished project, and having all the design files means I can whip up another batch whenever I need to. However, when I need to make, say, three thousand swarmbots or fill an order for a dozen PCBs, the traditional etching process can slow down the operation to a crawl.

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: 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...
DIY Lab Equipment: Make Your Own Litmus Paper Using Cabbage Juice
Home chemistry is great, but what happens when you forget to label your chemicals? How do you know if you turned a clear glass of ammonia into a clear glass of unobtainium? Chemists have a tool for just that.
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: Build a Light-Triggered Alarm to Catch Your Food-Thieving Roommate in Action
When I was attending college, my friends had a phantom thief in their dormitory. Almost every night, a different item of food would go missing, never to be seen again. There was constant speculation as to whom the thief was and how to catch them. Security cameras were deemed too invasive, but none could think of another method of surveillance... until today.

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.
Galactic Invasion: How to Securely Embed Tracking Electronics into a Rocket
Rockets are lots of fun when you are launching them. However, finding them can be an arduous if not maddening task. Fancy space rockets have lots of tracking equipment to make touchdowns as simple as pie. Today, we look at embedding LEDs into your hobby rocket for easy night flight fun!
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.
DIY Lab Equipment: Make a Magnetically Controlled Cigar Box Stir Plate
If you've ever been inside of a real laboratory, you probably noticed how expensive the equipment is. You'd never be able to afford even just one of those ultra high-tech machines required to splice genes or split atoms. Even the lesser machines can be prohibitively costly, including a stir plate.
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?

Make a Physical Computer Virus: Plant a Parasite to Prank Your Peeps
Computer viruses are terrifying. They are undetectable, dangerous, and operate constantly right under your nose. For the average computer user, there are only a few repair options. You could buy expensive antivirus software that causes more problems than it fixes, you can wipe your hard drive clean and lose all of your important data, or if all else fails—just switch to Linux.
How To: Create a Swarm of Robot Minions with These Popsicle Stick Arduino Hexapods
You're never too young to start building your vast swarm of robotic minions. Taking over the world requires a whole lot of robots.

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.
How To: Your Personal NASA Program from Garbage: How to Build a Pulsing Jar Jet Engine
Jet engines combine oxygen from the surrounding air with on-board fuel to burn at very high temperatures and create thrust in the direction of the flame. Rockets, which we will learn about in a later post, are similar but carry oxygen internally and can therefore function in space!
