NYC Resistor has a Epilog 35W laser cutter with a 30x60cm bed. It is one of the best rapid prototyping tools I've ever used -- I can go from quick sketch in Inkscape to an enclosure in minutes. Here is a selection of some of my favorite projects that I've made.
Command line laser cutting
The Epilog laser cutter at NYC Resistor officially only work with Windows, but that doesn't seem right for a hackerspace. I reverse engineered the HPGL dialect and have a set of command line tools to send PDF files directly to the laser cutter's LPD port over the ethernet. Read on for more info....
My open source boxer program generates SVG files for laser cut boxes. Pass in the desired dimensions, out comes a right rectangular prism that fits together. I've used it for almost every project, like Voronoi boxes, my Analog gauge and Morse Code keyboard.
ReplicatorG and SkeinForge can be used to generate slices of arbitrary thickness, so I used a 3D model from Thingiverse and cut it out of 3mm clear acrylic. The technique makes for a very neat mix of high XY resolution and very low Z resolution. Read more about this technique...
Lasercut Intaglio printing
One of my favorite things is to combine low and high tech. Here I writeup how to use the laser cutter to etch printing plates for intaglio method prints using our lithographic printing press. The 21st century meets 15th century in our house warming invitations. Read on for more details...
I wrote a perl script to convert images to halftone circles that can then be laser cut into stencils. They also cast very interesting almost coherent shadows. The script tries to optimize the cut order, but it still takes a very long time to cut so many small circles.
Voronoi lace boxes
I love the natural look of Voronoi diagrams after learning about them in a path planning robotics class. To design these boxes I wrote a script that outputs SVG of the Voronoi diagram and then combine it with my SVG box maker to create the delicate boxes. Each one is randomly generated and unique, although the ones above are available as thing:39415. Read on for more details on making the boxes...
Ada Initiative letterpress
The Ada Initiative commissioned a portrait of Ada Lovelave to use for their marketing materials and released it under a CC0 license. I lasercut relief and intaglio plates and printed a few different sizes for friends on the lithographic press at NYC Resistor. More photos of the printing process...
Settlers of Catan
Settlers of Catan is a fun game and I wanted to make my own version of the board. These laser etched and cut interlocking pieces make for a very sturdy setup. One is made from bamboo, the other is inked acrylic.
LED Ring Light
I experimented with a laser cut ring light based on a circular PCB of white LEDs that Adam brought back from China. They work fairly well, although the petal shaped hood of the 24-70 cases a shadow unless the light is at the very edge of the plastic.
