Merlin Armor

Alex Glow made some pretty cool light up Merlin Armor.

This carbon-fiber armor has an LED underbelly.  It uses NeoPixel LED strips to run light animations.  The armor pieces can be made to mix and match.  All pieces hook up to a battery back and micro-controller – both of which Alex made some 3-D printed holders to wear on a belt.

The LEDs are mounted so they face towards the skin to create an under-lit effect.

Code for the project, as well as the plans for the 3-D printed utility pockets, can be found on Hackster.IO Project page.

PixelBrite

LeoneLabs created PixelBrite, a study in pixels.  This amazing build is more than a light table.  It’s a digital Lite-Brite, minimalist light sculpture, a disco light, a sound reactive light show all rolled into one.

With batteries and a slot for and SD card to stream patterns without a computer, PixelBrite can act as a standalone light.  You can also plug it into a MIDI controller and have a interactive light show.

The Instructible page on the project is well worth reading.  It’s incredibly detailed and contains not only build details (like a complete bill of materials spreadsheet) but some information on color theory and display science as well.

The project is open source with the code available on GitHub.

WoodWind MIDI Instrument

Johan Berglund created this MIDI wind instrument that’s lightweight and fun to play.

It pressure sensor, capacitive touch keys, and pitch bend joystick to make a very expressive instrument.

More information can be found on this Tindie page where is was sold for some time, this project page (with lots of info and videos), and on the Tindie blog.

The project’s source code and documentation is on github.

Trees of Life Art Installation

Rick Van Melis created Trees of Life, a beautiful and interactive art installation that allows visitors to connect with the 2 trees and bring them to life.

The art installation features over 9,000 LEDs controlled by 8 Teensy boards using the Fast LED library. Each tree is a separate system. It has 6 hands and 12 ‘arteries'(LED-Strips) 2 out of each hand. These start at 1m50 and go 5 – 7,5m high.  Basically when untouched the tree and its arteries are in a restful idle animation. Users however were able to wake up the tree by placing their hands on the “hands of the tree” (hand shaped touch pads), when this happens the 2 arteries connected to the corresponding hand will start pulsating with ‘energy’.

Classic Organ Keyboard Interface

Pascal Leray has designed and built an keyboard interface for an amazing classic organ that he’s built.

Main board: dedicated to contacts or Hall sensor-based organ keyboards. Direct MIDI/USB output. This board has also a standard Parallel Port, fulle PC compatible. Up to 8 keyboards/pedal/knobs. Direct USB/MIDI output.

Interface board: can receive up to 64 digital or analog inputs. To be connected to the above board.

You can read about the organ project on his web page. (It is in French, but auto translation programs seem to work it)

Update:  Here’s a link to the English version of his web page

Beat Counter

Georg Ziegler built a pretty cool beat counter

Beat Counter counts beats and visualizes it using an 8×8 LED matrix by connecting a Teensy via MID to Ableton Live.

Stargazer Drone Machine

Ross Fish of Moffenzeef Modular has made an incredible drone synthesizer modular – The Stargazer.

STARGAZER is packed with features: dual wavetable oscillator with ninety arbitrary waveforms, two resonant lowpass filters, three wavetable LFO’s, sample rate reduction, bit rate reduction, amplitude modulation, and CMOS distortion. The expression pedal input can be used to control the speed of all three LFOs at the same time which free up your hands to control other aspects of the drone.   It’s also firmware upgradeable!

STAGAZER uses the Teensy Audio Library and is Ardunio compatible with code available on GitHub.

 

Computer Combination Lock

Eric Betts created a computer combination lock.

The lock uses the Teensy, rotary encoder, circular led bar graph, and the encoder library.  You twist the knob to the correct position as indicated by the LEDs, push down on the knob to set that value, and on the 3rd value the sequence will be checked against the first 3 bytes of EEPROM. If the combination is correct, “Secret Word” is sent as keyboard input.

The code for the project is available on GitHub.
