Using a Teensy 3.2 paired with an audio shield, the project aims to put a digital synth in an Otamatone that will include presets that can be configured on the fly. This could be very useful in making the instrument a bit easier to play. After all, the world needs a better Otamatone.
David Henderson and his brothers installed their own ambilight on the back of their new TV and the end result looks awesome.
Ambilight is a technology by Philips that uses LEDs mounted on the back of their TVs to add ambient light. David retrofitted his TV using a total of 100 addressable LEDs. The project uses a Teensy 3.2 and takes advantage of the FastLED library.
“A guy called Tom” made the Polaron, a 16 step, 6 track digital DIY drum machine.
Driven by his curiosity to understand and experiment with interaction patterns on digital musical intruments, Tom made the Polaron. It combines features from other drum machines that he knows and loves as well as new features he found useful during development. The current list of features includes:
16 step sequencer
6 instrument tracks
2 pots for parameter control
parameter locks: all instrument parameters can be recorded for each step
different pattern length for each instrument track
crunchy 12bit stereo outputs
This video show the Poaron in action with a Waldorf Blofeld keyboard synthesizer
The project is fully open source with the code available on GitHub
There is also Wiki page available with instructions on how to build your own
Measurement of impedance over a range of frequencies can be useful for testing speakers & microphones, monitoring corrosion in metals, and biomedical applications. Pick up a copy of Issue #344 for the full build details, including schematics & access to the software.
Inspired by the vortex manipulator worn by Captain Jack Harkness of Dr Who and Torchwood, this steampunk-esque wrist mounted device includes a lot of useful features. In addition to having clock, it also has a compass, picture gallery, heart rate monitor, and Dalek detector.
The device is powered by a Teensy 3.2 and uses an ILI9341 touchscreen for the interface. The Teensy worked out well as a development platform for the project. It had plenty of capacity to add more features as the project progressed, such as a heart rate monitor with an I2C interface.
Detailed information about the build can be found on this page.
Code and Eagle files for the project can be found on GitHub.
Magic Wheelchair, a nonprofit organization that builds epic costumes for kids in wheelchairs, matched ATMakers to a kiddo for a wheelchair build. ATMakers joined forces with MakerFX to build a wheelchair costume in 3 short weeks – in time for the Assistive Tech Industry Association conference.
Alex, the young man receiving the wheelchair uses assistive technology devices to communicate, so as part of the build the team decided their Bumblebee needed to be interactive using a keyboard. The interactions they selected could be usable by Alex and worked into his physical therapy in the future.
The dashboard has a capacitive touch horn, two assistive technology buttons, a 320×240 LCD video screen, and 3 addressable LED rings. The dashboard sends commands to the costume using USB MIDI notes. This allows the costume to be controlled by either the dashboard or a keyboard. All the controls and LEDs are powered by a Teensy 3.6 with a Teensy Audio Shield. They used the FASTLED Library and the Non-blocking WS2812 LED Library to control the LEDs. The USB Host capabilities of the Teensy 3.6 were used for the MIDI connection.
