Interactive Projector Screen

  We have seen lots of Projector Screen hacks over the last few years, this one demos the power of the system quite well. It doesn’t take much hardware to provide some fantastic results! The video game gun use is a natural extension of the technology. "The basic idea is really simple: a program running on the PC will process the images viewed from the webcam, find the position of

DIY Laser Etching Projects

  Baccus61 has documented some of his cool DIY Laser Etching Projects. He makes etching an image on a round bottle simple! After the jump are a few of my favorite videos he has created. "My new rotary attachment is finally ready after a couple of weeks in the making (I didn’t spend too much time building it though) It’s a Vexta 5 phase stepper motor coupled to a 50:1

Garage Parking Assistant - Basic Stamp Microcontroller Based

  This Basic Stamp Microcontroller Based Garage Parking Assistant may be overkill for the application but that is what makes it fun. 🙂 What fun would it be to hang a tennis ball from the ceiling when you can use technology to give you a traffic light that represents your optimal parking distance.

Underwater ROV Project

TrackIR - Head Tracking for Game Play

Now if only someone came up with an open source version of it since the prices seem a bit high. "As you move in your chair and rotate your head small amounts : your game-view will precisely correspond. You never

DIY XY Plotter

  Re-purposing old computer parts is great since it prevents working equipment from finding their way into the landfill. This XY Plotter is a great example of re-use of old equipment. "This XY plotter was made by the group at Next Window and is the work of Paul Marson and Keith Colson, for the purposes of calibrating touch screens. It uses components that were salvaged from two old Kodak flatbed

Lego NXT Rubik Cube Solver

  The most impressive part of this Lego NXT Rubik Cube Solver is that the NXT module does the computing that solves the cube! I wouldn’t have thought that would have been possible without having a PC do the calculations. Video after the jump. "Tilted Twister solves Rubik’s cube fully automatically. Just place the scrambled cube on Tilted Twister’s turntable. An ultrasonic sensor detects its presence and starts to read
