Our friend Sprite_tm has had some time to play a clever prank. Some HP printers have the ability for code to modify what is being displayed on the status screen. This HP Printer Display Hack uses that feature to make a stand alone module that displays some funny comments to the roommate that felt that it was OK to leave a bunch of printers laying around for others to
Seems like there is tremendous amount of information over at LUTEC Australia PTY describing their technology but is any of it real? I have seen lots of claims over the years form companies like this but none of them have turned out to be feasible. "In order to gain an understanding of the operation of a LEA (Lutec Electricity Amplifier) it must be understood that there are actually three
Mark Csele has built a Laser Light Show Controller based on the dsPIC 30F6012 microcontroller. There is a good operational description that could spark some of your own project ideas. "In a basic light show, a beam from a laser is deflected by two galvanometer scanner heads, each of which moves a mirror to steer the beam in the horizontal and vertical direction independently. Given the high speeds
This is a cool video that goes over the basics of DIY Combat Robot building. Nothing very high tech but there is lots of interesting tips such as using cheap cordless drills as robot motors when you are trying to build on the cheap. "RoboGames founder and SFSU School of Engineering instructor, David Calkins, gives Patrick a primer on building a combat robot. From the wheel and controllers to
If you have ever been interested in huge telescopes this site is for you. There is a ton of details about this huge 22 Inch Binocular Telescope. Make sure you have a look at the right column of the site, many of the suppliers that were used are listed. This supplier list will give you a head start when you start your build. 🙂
Could this be the breakthrough in energy that we are needing to kick out habit on fossil fuel? With the organic solar cell I think the scientists of the world may be onto something here! "MIT chemists Daniel Nocera and Matthew Kanan discover a new catalyst that speeds up the splitting of water into oxygen and hydrogen. The discovery may heighten interest in pollution-free fuel cell vehicles, which generate
Lack of sunlight at this time of year has many people experiencing Seasonal affective disorder (SAD). One way to overcome SAD is to be exposed to bright lights, with this Sun Track project you could reflect bright sunlight into your house where you may otherwise just have a dimly lit room. "The sunTrack system can reflect the sun in my house and keep the reflection all day. That way it
