For some time I have been toying with a couple of servos and a bluray laser. The bluray laser wavelength of 405nm is ideal for activating glow materials.
So with a small amount of trigonometry I've created a laser plotter, that will draw an, almost, undistorted stencil on a glow in the dark painted background.
Glow inc V10 green glow powder: http://glowinc.com/detail.aspx?ID=42 (I bought 1kg which was $160, you won't need this much)
Pololu Maestro Servo controller board: http://www.pololu.com/catalog/product/1350 $20, an excellent tiny servo controller board, provides C#.net support)
A couple of servo motors from www.hobbyking.com
and a servo signal operated on/off switch for the laser, also from Hobbyking http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=8833
I've been playing with my Kinect sensor for about a month now, and I've created a simple bubble menu system (and a ton of different alterations) using WPF.NET C# and the OpenNI Kinect Driver and .NET wrapper.
Have a look:
In the summer of 2010 I had the idea that I would build myself an electric bicycle.
With battery and motor technology maturing to a point where it would be feasible to build something that would actually get me to and from work and school without running out of juice.
I first looked at commercially ready products, 25 kph and 30km range pedal assist bicycles going for somewhere around 1000 Euro I came to the conclussion that I didn't have that kind of money for a joke like that.
So I built my own, and the result was a (including the brand new mountain bike) a 80 kph hour 25 km range LiPo battery powered brushless RC helicopter motor assisted mountain bike. This thing turns heads!
This is the very first testrun
A project I am currently refining and about to complete, is a C# .NET servo controlled bluray laser.
This thing can paint an image on a glow in the dark wall, using a 405nm bluray laser and some quick programming.
Here is a work in progress video
Once completed it can paint any stencil image, text onto a wall that I have painted with glow in the dark paint.
