How To: Build a Deadly Motion-Activated Airsoft Turret Gun
It's tough out there on the battlefield, especially when your stuck in the trenches and your comrades are dropping like flies. There's no hope. At least, until the next airsoft battle.

Wet-plate collodion photography is a process that lets you develop a photo onto a piece of glass. It has some neat applications, but it's not a simple process, and most people use a special camera to do it because the silver nitrate used to process usually ends up leaking, which would ruin a regular camera.
Earlier this week, we learned that you can get people to put more money in a tip jar simply by drawing eyes on it. But what if you want to keep them away from something? Eyes can do that, too, especially when they're Putin's.
Wall Anchors. Drywall Wall Anchors. Plasterboard Wall Anchors. I discovered these plasterboard (drywall) anchors / plugs a few years ago and think they are fantastic. They are ridiculously easy to use and are extremely effective in attaching fixtures to walls. One of the main things to be aware of (as with all things that have fixtures hanging from them) is the recommended maximum weight loading of each size of anchor. What ever the packet says, adhere to it.

It's September 1st, 1859, and the Earth looks more or less like something out of an apocalyptic movie or Sci-Fi novel. All communications have failed, it's so bright outside at midnight that people are getting up and making breakfast, and people all over the world are seeing auroras. The solar storm that produced the electromagnetic pulse and caused all this mayhem is known as the Carrington Event, and storms like it happen about about once every century.
As useful as they can be, 360-degree photos are a total pain to create. The process usually involves taking a bunch of pictures with expensive equipment or software, and not just anyone can do it. But a new iPhone app called CupChair changes everything—it lets you take 360-degree photos with nothing but your iPhone and a cup.
A few weeks ago, we saw a simple 128 inch DIY Projector Screen that looked like a pro built it—and it only cost $200. But this one is even cheaper, and looks just as good. It's also simpler because it's painted right onto the wall. In the video below, How To Lou shows us how to make it with just some white or silverscreen paint, a few pieces of casement molding, and some black velvet for the trim.

Anyone who does a lot of photography knows that the right exposure can make all the difference in the world.

Photographer David Johnson decided to put a twist on the classic long-exposure fireworks photo. Normally, when people take photos of fireworks displays, they just set a long exposure for somewhere over 3 ...
André Broessel of rawlemon has developed a solar energy generator that can use both sun and moonlight to create usable power. Oh... and it's gorgeous. The device is essentially a huge glass sphere filled with water that uses a ball lens to refract light in a way that increases energy efficiency by 35 percent. It's completely weatherproof and has an optical tracking device, meaning that it can be incorporated into architecture. Here's a concept design of how it could be used to power buildings...
It's been proven over and over that you can make batteries out of fruits and vegetables such as lemons, potatoes, and even apples. Turns out, passion fruit is also acidic enough to power a battery, but Maui Makers member Ryan K decided to take it a step further by adding a laser. Passion fruit, or Lilikoi as it's called in Hawaii, is usually over-abundant in Maui, so Ryan decided to put it to good use. Using anodized bolts, copper pipe, wire, switches, and some LEDs, he built a battery that c...
You've probably seen the classic fruit battery science experiment a thousand times, but I doubt you've ever seen it turned into an art project! Photographer Caleb Charland uses everyday objects like apples, coins and vinegar to create makeshift batteries, then takes these gorgeous long exposure photos. For the apple tree photo, Charland got about 5 volts for every 10 apples, so he had to wire 300 apples to power the lamp for several hours. He used a zinc-coated galvanized nail and copper wire...

I've never really liked to type on a flat or low keyboard. Even the small flip-up stands underneath most keyboards were not good enough for me, as those little legs aren't usually more than 2 or 3 centimeters high. I'd like a minimum of 5 cm, so I decided to make this keyboard base for myself. Aside from giving me the right height and angle, this DIY keyboard base also features LEDs that light up my monitor, the table, and gives a nice background to my desktop. It's even got a built-in stand ...
