How To: Make an Airsoft Machine Gun (AKA Halo Mobile Turret)

Airsoft doesn't get any better than a cloud chamber BB machine gun, aka Cloud BBMG. This design has an incredible rate of fire. If you've got a full charge of compressed air, it can easily fire more than 50 rounds per second at a 350 ft/s muzzle velocity. Since this is a legit airsoft build, it should be handled safely with the same care as any other airsoft firearm, and you should be wearing the same protective gear—protective mask, safety glasses, etc. My video details the build of this bea...

How To: Inject Your Drill Press Table Crank with Steroids

First, I would like to explain that among my family members, I am considered somewhat of an oddball. Mostly because of some of the mods that I have performed on a few of my woodworking tools. After I show you what I did to my drill press, you may be inclined to agree. When I first hatch an idea in my little pea brain, the first thing I take into consideration is whether or not this mod is irreversible and will destroy my tool. In the case of my drill press, I determined that it was safe to pr...

How To: Make a Mini Cannon From a Lighter

I love this project. It involves fire, projectiles, electricity, and is easy to put together from commonly available parts. This mini cannon fires airsoft pellets, is fueled by alcohol, and is made almost entirely from parts found in a standard BBQ lighter. The total cost is under $5. About half of the BBQ lighters out there have a divide in the gas reservoir which makes them not work for this project. In case you have trouble finding a suitable lighter, the exact one I use in this video is a...

News: Enter the Weird World of Hojamaka Games

Without Japan, video games would not be very fun. Atari's early work was important, but Japanese developers, publishers, and hardware makers were responsible for almost every major advance in video games for the first 25 years of their mainstream existence. In recent years, it has often been said that they have become less relevant than Western developers. In the indie games movement— (our area of greatest interest here at Indie Games Ichiban)—Japan does not have anywhere near the presence th...

News: Temporarily Disable Android Lockscreens with DelayedLock App

For those who need security on their Android devices, the standard swipe lock screen just isn't enough, so it's necessary to install applications like GOTO and WidgetLocker to enable either pattern, password or PIN protection.

You could be in a heated text conversation, following directions on a map or compulsively checking the news feed on F...

How To: MoMA Pisses Off Internet Artists (Here's How to Get Back at Them)

Aram Bartholl over at F.A.T. is pretty pissed because MoMA is discriminating against internet artists. As most New York-based working artists know, MoMA offers annual membership for only $35 (compared to the standard rate of $75) to artists who can provide "credentials" that prove legitimacy.

How To: Make Homemade Microwaveable Foot Warmers

Well, Ol' Man Winter is upon us yet again, blasting us with his icy breath. When I was a kid, I loved wintertime because it meant the prospect of sledding, snowball fights & missed school days in which to enjoy both.
