Laminar Flow Fountain - Maker Faire 2013

This year at Maker Faire Detroit, I helped Matt Oehrlein and the team from i3 Detroit with their laminar flow fountain. The fountain is composed of three laminar jets. Each jet shoots into a barrel containing the next jet, creating a ring. The individual jets are controlled by an Arduino which wirelessly communicates with a Makey-Makey connected to three brass candle holders. Touching two of the candle holders causes a jet to connect the corresponding two barrels.

Since the project was built in Detroit, and I'm living in Boston these days, I wasn't able to help with the fountain construction. Instead I helped create a "screensaver" demo to show the fountain off when there isn't any activity on the controller. I didn't have access to the electronics when I started because 1. they were in Detroit and 2. they weren't finished yet, so instead I wrote a simulator for the fountain in Processing and worked on it in Boston.

Since the team from i3 was using an Arduino to control the fountain, and the Arduino language is a subset of Processing, I was able to copy my demo code straight from the simulator and into the controller code. You can see the result in the video above, showing the demo running on the fountain with the simulator in the upper right corner.

I wish I could take credit for the fountain itself, because it turned out amazingly well (despite a lot of wind throughout the Faire). The demo was still a lot of fun to work on, and this project now has me thinking about more ways the Arduino/Processing combo can be used for remote collaborations.

Mind Flame: Maker Faire Detroit 2012

For Maker Faire Detroit this year, I collaborated with Matt Oehrlein to build MindFlame, a mind-controlled flame effect game.

MindFlame uses commercial EEG headsets from NeuroSky to read the brain waves of two contestants. The signal is sent to an arduino, which can determine (more or less) how hard the contestants are focusing. When a contestant focuses hard enough, the arduino activates a solenoid, releasing a burst of propane past a glowfly ignitor, causing a giant burst of flame. The goal was to be the first person to get to four bursts of flame.

This project was tons of fun, and collaborating with Matt was great because we had twice as much time and resources to throw at the project, and I think the end result was much more impressive than we could have done individually. Plus, controlling fire with your mind is just awesome. Josh “Bacon” McAninch (from the Gon KiRin project) helped us with the flame effects, and Maddy "Brodi3" Winans helped us design and decorate the apparatus.
