CO2 Powered Nerf Gun

Frank — Wed, 05 Jan 2011 13:24:53 +0000

Instructables hacker Philysteak527 modified a Nerf gun, making it semi-automatic thanks to the modern marvel of compressed air. This mod isn’t for the faint of heart since it involves the design and manufacture of a bolt-action the fit’s the specific gun you are using.

Philysteak527 used some polyoxymethylene plastic and a CNC lathe to create the parts needed for the bolt. Toss in some brass fittings, a solenoid, tubing, and some electronics and your set. Check out the footage of it in action after the break. You will definitely be the big boy in the school yard with this. You might very well have the SWAT team called in as well.

3D Video With One Camera

3D video has really started to make a strong comeback. I remember being a kid when the paper glasses with red and blue lenses were all the rage. Technology has changed a lot since then. The cost of creating 3D videos is so expensive that it prohibits the aspiring film maker from considering the option, but if you happen to have a CNC machine that you can access your on your way to brining that dream to life.

Gabriel, the crafty hacker, is using a SketchUp to plot the camera paths, a plugin to export those paths and automatically adjust them for perspective and a CNC machine to preform all of the movement. You take a pass at something for the left eye then the CNC machine takes a second pass at a different perspective for the right eye.

Simple eh, well it does have it’s drawbacks like the inability to shoot anything that’s moving. Although this isn’t the perfect setup, it does show you how creative some people can be. Maybe this would be perfect for stop motion 3D. Check out the two videos after the break. The first is the actually 3D video and the second shows a behind the scene on how the whole rig works.

Have you ever wanted your very own CNC machine but just never been able to pony up the money needed to get one? Have a peek at this one that Tom McWire slapped together. Video after the jump.

“Here is a way to make a computer controlled milling machine. That puts the real power of a computer control machining into the hands of the average human. Small enough to set on the desk but scalable to any size. As inexpensive as possible without sacrificing accuracy (too much). All most all the parts can be purchased in local retail stores. And above all CHEAP you can be up and running for well under $200. With it you can do 2 Dimensional engraving and PC board etching and 3D milling and modeling in Foam, Wood, Plastic and other soft materials.”
