Hacked Turntable rotates humans for 3D scanning

If you are from the 70’s, you’ll probably remember the Disco Body Shaper or the Aerobic Body Shaper exerciser devices that were the rage of the day. Basically, Lazy Susan turntables on which humans could stand and twist away to burn fat. The results were suspect, but [Daniel Kucera] thought one of them would be ideal in 2016 to build a heavy-duty turntable to allow full body scanning.

He had already tried a few other ideas and failed, so it was worth giving this a shot, since it cost just 10 bucks to buy one. The plan was to use a motor to provide friction drive along the circumference of the turntable platform. For this, he used a high torque motor with a gear on the output shaft. From the looks of it, he attached a Meccano plate to the base, and mounted the motor to this plate. A large spring keeps the motor pressed against the rim of the turntable. A strip of rubber scavenged from a bicycle tube was glued along the side of the turntable to provide some friction to the gear drive. The turntable is placed on two thick pieces of foam, to provide clearance for the motor. We aren’t sure if a toothed gear is the best choice to drive this thing, but a hacker’s gotta use what he’s got. He’s clocking 190 seconds for a full rotation, but he still hasn’t posted any scan results from the Android scanner software that he is working on. This one, for sure, doesn’t qualify for a “it’s not a hack” comment.

Simple telepresence hack lets remote user rotate this laptop

[Kris] wanted to make the telecommuting employees at his office feel a little more in control of their virtual presence in the office. He gave them a way to look around without needing to go into full-blown robotics. This laptop stand has a Lazy Susan connected to a servo motor to give the user control of where the computer is pointed.

We’ve certainly seen our share of really complicated surrogate builds like this balancing robot. There have been simpler options too, such as this smartphone-carrying motorized base. But when you get right down to it, the ability to pan the camera is probably good enough for most situations. [Kris’] solution can be built in an afternoon, using simple materials. The box is made out of MDF with a base for the laptop connected by the ball-bearing hardware that supports the weight and makes sure the servo is able spin it freely. It is driven by an Arduino which connects to the computer via USB; making it easy to control remotely. Check out a quick clip of the laptop going round and round after the break.

Arduino powered singing table

This musical Lazy Susan, or “Crazy Adam” was brought to us by students from MIT.  It basically plays [Soul II Soul]’s “Back to Life”  as it turns.  In their words: “Through the interaction with the Singing Lazy Susan, we found the eating patterns and behaviors unique to each person, which reflect our personalities and interests. The dining experience expands to a new domain.”  Are we the only ones who think this is silly? Not only is an Arduino overkill for this, how does this help reflect our personalities and interests? We know, someone will say that art doesn’t need to make sense, but  this would just get annoying really fast. Good job coming up with an idea and making it happen. Please don’t bring that to our next office party. It is also worth noting that musical Lazy Susans aren’t exactly a new idea.
