Drawing a 3D Scene in Blender with a Pen Plotter

Pen plotters are an attractive tool and toy for anyone interested in computer graphics or generative art. The simple machines draw with a pen or pencil on paper under the control of computer code. Possessing infinite patience, such machines can build up complex imagery defined by digital information or rule

Sound Machine Sound Swap

Replacing the samples on an obnoxiously loud and irresponsibly cheap sound toy.

Hex Bug Swarm

For an art project during a hackathon at the MIT Media Lab we wanted to have a swarm of "creatures" under computer control. The concept called for these creatures to participate in a simulated society, which would be guided by a crowd of humans online. They had to look like

SMT Part Tape Counter

I wanted to get a handle on my Digikey SMT part cruft, but didn't want to count the parts by eye. Built a simple 3D-printed sensor block with a break-beam sensor that I can easily slide the SMT part tape through and hooked it up to a simple Arduino shield

A Tiny Cloud

Infrastructure as a Service, for when you need infrastructure made of the ittiest bittiest computers.

Plotting Images Bigger than the Plotter

Artmatr is a company that I was working for at the time. I wanted to make a sign with the name for the wall of our lab.After I got an AxiDraw I wanted to combine it with the Vive tracking experiments I was doing at the time. I had

Lofi Calculator AR

Off-screen there is an Arduino Nano plugged into the communication port of the TI-83 which is converting a stream of video data (96x64 monochrome frames) into the TI port protocol. An assembly program on the calculator very rapidly transfers the video data to screen memory. A 3D scan of me

Remote Controlling a TI-84+ from a PC

There is a remote control protocol baked into TI 84+ graphing calculators so that it is possible for Texas Instruments to make products that take control of calculators in the classroom via their link ports. I implemented the protocol on an Arduino and made a control program in Ruby to
