R/C Rocket-Beest Burns Up Fuses Out There Alone

We’re beginning to think the “S” in [Jeremy S Cook] stands for strandbeest. He’ll be the talk of the 4th of July picnic once he brings out his latest build—a weaponized, remote-controlled strandbeest that shoots bottle rockets. There are a bank of money shots up on Imgur.

This ‘beest is the natural next step after his remote-controlled walker, which we featured a month or so ago. Like that one, the locomotion comes from a pair of micro gear motors that are controlled by an Arduino Nano over Bluetooth. The pyrotechnics begin when nitinol wire cleverly strung across two lever nuts is triggered. All the electronics are housed inside a 3D-printed box that [Jeremy] designed to sit in the middle of the legs. We love the face plate he added later in the build, because those gumdrop LED eyes are sweet.

Can you believe that this vehicle of destruction began as a pile of innocent, pasta-colored pieces of kit? We dig the camouflaged battleship paint job, ’cause it really toughens up the whole aesthetic. And really, that’s probably what you want if you’re driving around a spindly beast that can just shoot rockets whenever. Let’s light this candle after the break, shall we?

Homemade Bazooka Has Earned Its Stripes

Many of us dream of launching rockets from our shoulders, but [John] here actually did something about it.

This bazooka build started with a 6″ diameter PVC pipe. He mounted a length of 80/20 T-slotted aluminum extrusion to the pipe through a couple of wood blocks. [John] installed rail buttons on some Estes Alpha rockets which slide along nicely inside the T-slot. He welded a PVC cleanout fitting and plug to one end for easy access and gave her a nice paint job.

The ignition is simple: an irresistible red push button is wired to a 9V battery and a pair of alligator clips. [John] loads up a rocket, puts the gators on the wires of an igniter, pushes said button, and Bob’s your uncle. All he needs now is a pair of gun boats. Video of the build and some demonstrations we don’t necessarily recommend are after the jump.

Controlling Weapons With Kinect

kinect_rocket_launcher

It was only a matter of time before someone would figure out how to weaponize their Kinect. Hacker [Jonas Wagner] was fiddling with his Kinect one day and thought that it would be cool to launch missiles simply by gesturing. Not having any real missiles on hand, he settled for controlling a USB-powered foam missile launcher instead.

He mounted a webcam to the top of his rocket launcher to record video of his victims, and with a bit of Python along with the libfreenect ilbrary he was well on his way to world cubicle dominance.  The Kinect waits for him to pull his hand out of its holster in dramatic fashion, monitoring his movements for tracking purposes. Once the launcher has been armed, the Kinect watches for [Jonas] to pull his hands out of frame before firing the rocket.

We doubt you’ll see this thing controlling weapons for DARPA any time soon, but it’s cool nonetheless. The launcher seems to move a touch slowly, but we’re guessing that with an uprated servo, things could be a bit snappier.
