Monica Houston built these awesome flaming LED palm trees for her camp at Burning Man.

This was Monica’s first fire art project.  Her motivation for the project was to impress her friends and having something fun to take to festivals and parties.  It was important that it be interactive so a control panel was made to allow people to generate poofs of flame.

Two controllers are used.  A Teensy 2.0 controls the propane valves and sends messages to a Teensy 3.2 animating 1200 LEDs in sync with the flames.  Complete source code is available on github.

Staci Elaan hacked a megaphone to make it into a Dalek voice.

The 30Hz ring modulation and diode clipping is done using the Teensy Audio Library.  Code for the project is published on Pastebin.

The decorative additions to the megaphone make this magnificent ….. Magnificent …. MAGNIFICENT….

Kenneth Marut made a very cool, battery powered, hand held, digital synthesizer – Moon Germs.

This compact synth uses a combination of buttons and triggers to produce different waveforms and effects. An 8×8 LED matrix shows information while use.  It also uses an IR proximity sensor to modulate frequency.  In recent updates to the project he synth engine was restructured to include a Low Pass Filter and Low Frequency Oscillator (LFO).

As a lifelong musician Kenneth wanted to explore digital synthesis and experiment with unique ways of interacting with a synth using minimal buttons and knobs.  He hadn’t really explored digital synthesis before and decided dive in using a Teensy 3.2 and audio shield.

Be sure to check out the HackaDay project page, it has a lot of great information.

Code for the project is available on GitHub
