This may come as a surprise to many, but this is my first Arduino program. Running on a tiny Digispark!
My booth at the Bazaar Bizarre. I’m here at the Concourse Exhibition Hall in San Francisco all weekend. Come on by!
Fresh from the laser cutter! Parts for another museum piece for the Curiodyssey at Coyote Point. Can’t wait to get started making it.
A short GIF (hopefully animated) of my sample project for the Introduction to Mechanical Sculpture class at the Crucible. Made from a small shadow box and nylon gears, the input crank is split into two movements: one slow rotation of the bird’s body, and one quick oscillation of the bird’s wings. The fun part is that the axles for the two movements must be on the same axis, so one is a tube. My students are making excellent progress on their own machines, leaving me some time to shoot silly GIFs.
Here is my pile of unfinished buckles and bottle openers getting ready to be either electro-plated or brushed. Getting Kickstarter rewards fulfilled and also preparing for holiday season!
I built a jig to bend brackets for belt buckles! The body is mild steel, but two small spring steel pins form the actual bending points (the brackets are 304 Stainless, so they would wear out mild steel surfaces quickly). When the jig bottoms out, it presses two spring-loaded arms at either side, which over-bends the bracket just a bit to help with spring-back. The result is an almost perfect 90 degree bend!
Here is a brief slideshow of how I built the Post-Imperial Shaker. The frame of the machine is built simply of 2x2 angle-iron, with 3/4” dia. supports for the axles. I used shaft collars welded to the supports to house the bushings and bearings where the axles rotate. The key mechanism here is the “crank slider”, a sort of piston which allows a rod connected to a crank (on the flywheel) to pivot and slide, creating an elliptical path where the shakers are.
