Wanting to make an impact on the sidewalk quickly? This Spray Chalk Machine is sure to get that done. “This device is controlled by two Arduino Duemilanove boards, which apparently base the chalk “dot†timing on encoders sensing movement in the two wheels that the cart rides on. ”
Computer engineer Lassee Laussen and software engineer Ken Madsen built this ABB Robot made of LEGO bricks. It was an 8 month build to recreate the complex 6 axis machine. If you are interested in seeing some other interesting projects from Lassee and Ken have a look at Brick It. “The LEGO version of the IRB 120 is so accurate that it mimics every shape and curve. It also

This is a work in progress by Ye Guan, his Bipedal Walking Sentinel Project is a work in progress but the goal is challenging and Ye is making good strides towards a functional walking robot so far. What he is going for is a robot that looks something like the sentinel walker from Warhammer 40k and the two legged walker from Star Wars. “Â The robot will have a complete
There will come a time when you have too much electronic junk laying about ready to take apart such that you can’t easily walk around. The obvious solution is to make some Electromagnetic Boots for Walking on the Ceiling. Via:Â Hackaday “The magnet shoes themselves are easy to make and i can see people trying this. The tricky part is walking upside down, the ropes which have switches on
I will have to make it out to a Maker Faire one of these days. Looks like a blast and they keep getting bigger and bigger! Thanks to Matt Walsh, Rachel Lea Fox, Anouk Wipprecht and Brice Arnold for the cool footage. Â
We have all seen what a Ruben’s Tube looks like, check out the Pyro Board which is a 2D version of that. It has two speakers instead of the normal one. The results are impressive when a sign wave is pumped into the board but when some music is played the effects are very memorizing. I think this is the modern version of watching a campfire.  Thanks for the
