Mandala Coasters

I wanted to make a good friend of mine a house-warming gift. I wanted something that was elegant, useful, and took advantage of the free tools I had available: 3D printing, laser cutting, vinyl cutter. I saw some very cool 3D mandala designs on Thingiverse, but didn’t think they were particularly practical as coasters, neither do I think 3D printing coasters is particularly cost effective. However, … Continue reading Mandala Coasters

Stereographic Projector Lamp as Wedding Gift

My two bosses got married to each other this summer. (Weird, right?) My coworker and I decided to make a really awesome wedding gift for them and spent a long time dreaming up crazy ideas. Eventually we settled on something inspired by the shapes Henry Segerman was making on ShapeWays and Thingiverse: a stereographic projection lamp. (Funny story, he happens to have also made some … Continue reading Stereographic Projector Lamp as Wedding Gift

Electronic Mural: Part I

The circuitry for the electronic mural I made in the first two weeks of January (final product post here) was simple. I used three types of circuit stickers: an LED sticker, a sound sensor sticker, and a micro-controller sticker. Each sticker had the required components embedded, such that I just needed to connect everything. The challenge of the mural was not in the circuit design … Continue reading Electronic Mural: Part I

RhinoScripting for 3D CAD

My housemate Moon Duchin is interested in 3D printing these shapes that she studies. (She’s a mathematician.) The technical name for the shapes would be spheres of radius 1,2,3 in the Carnot-Carathéodory metric on the real Heisenberg group induced by a hexagonal norm. It’s a mouthful. I’ll probably do another post describing how to come up with the shapes. Anyway, she’s actually already had two … Continue reading RhinoScripting for 3D CAD
