Here are a few of my favorite projects I’ve developed. Many of these are open source – so you can build your own!
Electronic Cloud Chamber
I developed a technique for creating a cloud chamber using Peltier coolers. Cloud chambers let you see paths left by radioactive particles as they pass through a supersaturation of alcohol vapor. I made a few pre-assembled versions – and are in use places like New York Hall of Science and Notre Dame.
Flappy bird for Google Glass. Blink to flap!
3d-printed Friction Bike Shifter
A 3d-printed bike shifter I designed using SolidWorks. Surprisingly durable.
An open source motor control system that allows a robot to both drive and spin on a single wheel (“translational drift”). Uses either an accelerometer or gyro to calculate orientation. Many combat robot builders have implemented versions of this system on their own bots.
An OpenSCAD script I developed to create spherical 3d-printed loud speakers.
An interactive magic wand prototype for a client. It incorporated RFID, gyro/accelerometer module, infrared and a bunch of LEDs. I designed the 3d-printed enclosure in SolidWorks.
Open source bike chainring design software. The CNC mill I have isn’t really intended for use with metal – so I figured I had to try…
Arduino Laser Show
Turns out you can make a laser show using some old speakers, an Arduino and some parts from
Radio Shack the internet. I later developed a version that interfaced with twitter to display tweets matching specified hashtags.
