Have a look at the cool project that the guys over at Pumping Station: One made, it’s a Tron Bike! You can see the look they were going for below the video below. Via: Make “By far the coolest part of the project was making UV reactant ice cream. The secret ingredient in this is Fluoroscine, whose only side effect is turning your urine neon yellow. “

I’m not much of a gamer but I think this Racing Simulator by Motion Sim could cure me! Have a look at the first video below to get an idea of what this system can do. The company that makes it is actually in the industrial automation business so they clearly have a good handle on what is needed to fling around the 300KG that the system is rated to handle. “The full motion platform was created on the bases of the development for the 737NG project www.737ng.cz Its development took almost 2 years to reach the pre-serial production stage. A series of problems had to be solved throughout the development. The particular realization of the projects itself is quite a unique solution with regard to the components used and their connections. This would justify a separate article alone. Nonetheless, a big problem was to find a solution that would facilitate clean and quiet operation and also provide adequate load carrying capability and motion dynamics. After a line of experiments, a concept using non-synchronous motors and cogged belt gearing was used. It was necessary to work out a way to use these electromotors as servo drivers, especially at low RPM settings. In the end, a solution was found using intelligent converters and a specially designed control system. The result is an almost noiseless, compact platform which is able to operate without any special requirements.”

The guys over at Nerd Kits have made a cool Human Theremin project that uses Infrared Light. IR light from an infrared LED is bounced off someones hand and some of the light is reflected back onto an infrared transistor. The closer the hands are the more IR light is reflected back onto the IR transistor. The output of the IR circuit is fed into a Nerd Kit microcontroller and sounds are created based on the analog values. As Humberto demonstrates this makes for a cool wearable project that allows for cool interactions. The same IR technique was used in the Nerf Gun Hack when an IR LED and IR transistor were used to make an invisible beam which fired the gun when crossed. “This project recreates the properties of a musical instrument called the theremin. A theremin is played without the performer having physical contact with the instrument. A “normal” theremin uses two antennas and changing electric fields to sense the position of the players hands (not unlike our previous Capacitive Proximity Sensor from last Halloween); one hand controls the pitch of the note, and the other hand controls the volume or amplitude of the note.”

Have a look at this crazy University of Pennsylvania Quadrotor, just think about the issues getting stable flight not to mention the flight recovery this Quadrotor is capable of.

Jason sent in his latest creation, it’s a 1.25kJ Coilgun. Check out the cool video of it below, you will get a good overview of how it works and see it in action. I like the fact that he is re-using some parts in the build like the cell phone charger for some of the low voltage circuit needs. By the looks of the damage caused by the gun I am thinking that this might be the most powerful one we have seen yet. I like the dial that allows the max charge voltage to be dialed in so that the system can’t overcharge. Pulling the trigger disconnects the charge circuit and triggers the SCR which dumps the capacitor energy into the coil. If you like coil guns make sure you have a look at some of the others we have featured in the past. “Some technical data: - Action: single stage, bolt

Ben Heckendorn is known for his crazy hacks like the XBox 360 Laptop. He is hosting a web show on Revision 3 called The Ben Heck Show. The show will be broken up into 2 types of builds, he will be taking suggestions from the audience and he will also be covering a large build that will be covered over many episodes. I wonder how he got the suggestions for episode 1? Watch the video to see how a normal game controller is converted into a one handed controller that lets the player use his feet to control the other functions that the other hand normally would. The big build is the first stage of a XBox 360 Laptop build, it will be constructed using a XBox 360 Slim. |

If you have a CNC machine you can easily convert it into a high resolution scanner. All you need is a $20 web cam and a bit of software. In the video above Andy Grevstad from Tormach demonstrates how easy it is to slap a part onto the CNC bed and have the entire part scanned so that the part can be copied. Click on some of the images below for a look at what the scanned results look like. Via: Buildlog.net “CNC Scanner utilizes a Mach3 plugin to take a series of photographs where the camera is automatically positioned for each photograph with CNC motion. A dimensionally scaled photomosaic is then assembled by stitching photographs together to build a larger image. After the photomosaic is assembled, it can be opened in Tormach CNC Scan CAD, a simple 2D CAD program with basic functionality for measuring distances and tracing shapes. This information can be exported as an industry standard .DXF file to other CAD/CAM programs for further work. CNC Scanner uses a spindle mounted adjustable focus USB microscope camera that features our Tormach Tooling System® quick change mounting system. It is also compatible with any CNC mill that utilizes Mach 3 control software. Requires a spindle that is capable of holding ¾” shank, such as R8 or MT-3.” |
