built a controllable laser pointer!
it consits of a 5v laser module and two servo motors hold together by cable straps and is controlled trough a pololu serial 8-bit servo controller by some python code.
the laser module is simply switched trough the serial ports DTR line, that gives pulses as fast as the serial connection speed.
very unstable thing, but good enough to draw some crappy pictures on walls by taking long exposures (check the exif tags)!
its not easy to speed this thing up since you soon come to the point where you have to calculate the timing of your laser pulses with estimated servo speed and momentum. physics, basically, but i ran out of time to develop it really into someting. next try maybe with an arduino and some realtime assembler code..
Skinned the remote control box as the Mad Lights. Might as well make them look as integrated to the world of Mystery Science Theater as possible.
I created a Chirping Wheel of Time for my friend Howard’s 69th birthday. This kinetic art piece spins a wheel of winged ‘pataphysical talismans, in short bursts of motion that sound like a bird chirping. To illuminate the artwork, a circle of lights all around the wheel cycles through the colors of the rainbow.
The wheel was designed in Illustrator and laser cut on thin birch plywood. I then glued the pieces together and sprayed them, using black for the background, gold for the wheel and silver for the wings. A continuous servo motor spins the wheel, while a NeoPixel LED strip provides the illumination. Both are controlled by an Arduino Uno microprocessor.
Vive la ‘patapahysique!

We've been using Ardweenys in a bunch of projects, and this is one of those "wouldn't it be handy if..." items we designed.
Throw a beefy 5A regulator on, and it will drive 12 servos for 3 minutes before succumbing to heat load limitations.
From a sign mag, which game me inspiration to start doing sign fonts on freights. Expect more of these comin' up. As well, these YVRR freights have started appearing, same style as the HS boxes, but apparently these are from the upper mid U.S.A Yatican Valley Railways. Yes!
Working on a "top down" building approach means those Technic rods are just sitting where they happened to be for things to work, as opposed to actually being planned out. This will come back to bite me in the butt. Repeatedly.
I designed this laser cut kit of parts for assembling a scotch yoke, a mechanism for converting rotational motion into linear motion. I'm using it to control a physical camera based on the position of a virtual camera in an After Effects animation to achieve a match move.

New!Tom's head articulation revealed. The eyeball stalk is what will push up against the underside of his beak, allowing it to open. A massive Technic turntable will be responsible for the head turning.
