The latest DIY ideas, techniques and tools for bikes, rockets, R/C vehicles, toys and other diversions.
Randy Sarafan writes: This Simple Bot was inspired by a work by artist James Rouvelle called Colony in which a bunch odd shaped ovals self-propel around their environment. It is my understanding that his bots were made by placing a vibrating motor freely inside of a Styrofoam ball that was then coated to give it […]
The ARM powered Motorola Droid controlled LEGO Mindstorms NXT robot called MultiCuber 777 solves a 7x7x7 V-CUBE 7 in 38 minutes 54 seconds.
My significant other was recently given one of these Woodbaby shoulder puppets by a friend of hers who frequents renaissance faires, where the Woodbaby is a popular commodity. The puppet features a strong magnet in its base that mates with a curved metal “shoulder plate” that goes under your clothing and keeps the figure firmly perched on your shoulder. The mechanical control cable (which, per this thread discussing a DIY version, are R/C airplane control surface push-rods) runs to a simple controller that can be concealed in a pocket and manipulated to make the figure turn its head and look around in a surprisingly life-like manner. More elaborate versions have additional controls like wings and blinking, light-up eyes. Flickr user JeffreyWiden made his own. Would be cool to see an electronic version with a wireless control fob.
O’Reilly author Alasdair Allan (Learning iPhone Programming and the upcoming Programming iPhone Sensors) talked about using the OpenCV framework for face detection at OSCON in Portland, Oregon. In the video above, Mac Slocum interviews Alasdair from the expo floor of OSCON. For more information on Alasdair’s talk, check out his summary and slides.
This monster robot, according to the NXTStep, packs 9 NXT bricks controlling 16 Power Functions motors. Sweet!
.all of a sudden, flying around in Google Earth really felt like flying, and exploring the ocean trenches was like piloting a submarine. When you splashed through the sea surface you cringed slightly, expecting to get wet. You could even command your own lander down to the Moon or Mars…With the Liquid Galaxy, we could fly through the Grand Canyon, leap into low-Earth orbit, and come back down to perch on the Great Pyramid of Giza without even breaking a sweat.
Personally, I find the mark of a really gifted Lego artist is that his or her work makes you look twice and say, “Wait, that’s made out of Lego?” Renowned English builder Peter Reid (aka Flickr user legoloverman) consistently achieves that effect, for me, by obsessively permutating all those little Lego odds and ends that aren’t shaped like conventional bricks or plates at all–minifig arms, hands, and tools; Technic elements; pneumatic hose connectors; etc. These arms are part of a recent “assembly line” diorama of a future factory assembling his iconic “Turtle” robots.
