This tiny dog robot kit by G-Robots looks like it will be lots of fun. I can’t find a place in North America that sells it yet though. I have no idea how they got the servo motors to move so fast! Have a look at the first video that was shot by Robot Watch and notice how quickly the servos move to certain positions. The kits looks like
I am looking forward to the day that we can grow fresh vegetables in a small machine that takes a bit of room in the kitchen. By looking at this technology by Gabriela Mombach it may not be far fetched. "By designer Gabriela Mombach, the Broto Domestic Greenhouse grows plants through aeroponics (in which nutrient mists replace soil) while constantly measuring pH, temperature, nutrients, and humidity. A row of
Power Labs has put together a nice powerful Coil Gun. The principle behind most of these coil guns are the same however it looks like Sam has some nice tools that make the job a bit easier. "The gun has been completed, and it works! I finalized the design so that I could show it on my presentation on electromagnetic accelerators -which mainly focused on the Rail Gun- for
Thanks to Csaba for sending in this very nice looking display. The frosted blue LEDs have a great effect! Project code (zip). "Motor An old tape recorder motor. With this load it can rotate about 7.4/s. The image is flashing, it should rotate about 25/s. For supply a 7809 IC is used. Supply of the rotor The commutator of another similar motor is used (crw_1511) and a 3 phase
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
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
