There's a lot that goes into making a nice crystal radio set, so this is going to have to be broken down into two parts. The first part is the actual making of a functional radio, and the second part is making the whole arrangement look nice. In this part, I'm actually going t ...more
There's no doubt you've heard the old saying, "When life gives you lemons, make lemonade." The phrase was penned in an obituary to a dwarf actor in 1915 by an anarchist named Elbert Hubbard, who lost his life five months later aboard the RMS Lusitania when it was torpedoed by ...more
Silence spreads over these mountains like nothing I've ever felt. If I didn't have Moby blasting in my earphones, there'd probably be no other sounds around. Well, except for someone, Phil probably, murmuring in a nearby tent just low enough to make his words indiscernible. W ...more
It's hot this summer, but it's not that easy to cool down when you're on the go. You can't take an air conditioner with you, and a handheld fan will just tire you out, so you'll need to find more creative ways to cool down when you're on the go. One of these ways is a DIY sola ...more
A deck of cards may be a magician's best way to demonstrate his or her's sleight of hand, but for the prankster, it's the perfect way to deliver a shocking 300 volts of electricity! And that's exactly what I'm going to show you how to do today. Stuart Edge used it in his "Elec ...more
When the power goes out, having the ability to contact others becomes extremely important, and your cell phone can be one of the most important tools to have. But if the power is out for an extended period of time, battery life becomes a constant problem. Without the ability ...more
Sometimes I forget that I'm also a fiction writer, so I thought it might be a nice change of pace to share one of my stories with you. I wrote this piece awhile ago for an anthology that never came together and I'm tired of just sitting on it. It's one of the more odd stories ...more
Fireworks are the best part about the Fourth of July and other celebrations, but they can easily cause accidental injuries. It's both safer and more fun to set them off remotely, so we'll hack some standard fireworks with nichrome wire, a relay, and an Arduino to ignite remote ...more
In this experiment, we're going to get Mn2O3 (manganese(III) oxide) from MnO2 (manganese(IV) dioxide). Mn2O3 forms brightly red or a dark red colored crystal. It is used in Li-ion batteries, since (in a form of a crystal) it conducts electricity (much like MnO2). There isn't ...more
I don't like paying for repairs, and I don't like purchasing extended warranties. When one of my gadgets break, I perform emergency surgery and try and fix it myself. It doesn't always go well, but I've managed to resuscitate a few iPhones, an HDTV, an Android tablet, multiple ...more

Food waste is a topic near and dear to my heart, but the truth is, no matter how dutiful we are about finding ways to double-down on food scraps, a lot of stuff goes into the trash needlessly. Composting is the obvious answer. This is the process of taking organic waste (thin ...more
In my days as a hardware tech, I often came across motivated do-it-yourselfers who watched a video or two on how to repair a phone and thought that they'd give it a go. More often than not, they failed miserably and damaged their phones (and wallets) even more in the process. ...more
Welcome back, my budding hackers! People often ask me, "Why are you training hackers? Isn't that illegal?" Although I usually give them a short version of this post, there are MANY reasons why YOU should be studying hacking. Before I begin, I want to re-emphasize to all of y ...more
