Teenstrument64-LC

Jonathan Payne made the Teenstrument64-LC, a cool MIDI sequencer made from an Adafruit Untztrument.

This device features 3 instruments on 3 MIDI channels as well as a 32 step sequencer for each instrument.  It takes advantage of the native Teensy USB MIDI stack and also connects to an iPad using a USB camera connection kit.

LED Wall Visualizer

James Best a very cool wall mounted LED music visualizer that lights up his room more than the over-head lights do.

Armed with blue tape and some hand tools, James got to work mounting 900 WS2812 LEDs.  After a miss-step with some Gaffers tape and some sanding, the adhesive on the LED strips adhered nicely to the wooden base.  The original Arduino didn’t have quite the processing power needed for the project, but the Teensy 3.2 with built in Direct Memory Access (DMA) was up to the task.  The final enhancement to the project was a diffuser to help hide the internal components.

Additional information on the project can be found on this page.

 

 

Dandelion Hunter

Arduino “having11” Guy created an autonomous robot to hunt down and destroy dandelions.

After being frustrated a dandelions out pacing his grass between mows,  Arduino Guy (who also does project consulting for) built a robot using a Devastator Tank Cassis from DFRobots, a Pixy2 Camera, and a Teensy 3.5, to roam a yard to identify dandelions and chop them down.

Additional details as wells as the code is available on this Hackster.io project page.

Mega/Due Shield Breakout Board

Daniel Gilbert (Tall Dog on Tindie) has developed a breakout board that let’s you easily use Arduino shields  with the Teensy 3.5 or Teensy 3.6

This convenient board includes all parts needed to assemble a breakout board that allows you to connect a Teensy 3.5 or Teensy 3.6 to shields designed for the Arduino Due and Mega.  It features switches to select between USB or external power as one to set the US host port’s power mode (used for the Teensy 3.6).

USB MIDI to 12 Gate and 16 Control Voltage Outputs

Sebastian Tomczak has improved his USB MIDI device from 8 gate and 16 CV outputs to 12 gate and 16 CV outputs.

This handy device has 16 control voltage (CV) outputs and 12 gate outputs.  USB MIDI channels 1 – 8 are mapped to CV outputs 1 – 16 for pitch and velocity, and gates 1 – 8 for note on and off events. Gates 9 – 12 are mapped to note on and off events only on channel 9, and also will send a sync and transport signal based on MIDI clock messages if received.

This is a new version of of a project we previously covered.

Schematics and a build guide are published on Sebastian’s blog.

Code for the project is available on GitHub.

PhOut12 – USB MIDI Motor Controller

Bryan Jacobs of Knick Knack Sound built PhOut12, a motor shield controlled through USB-MIDI.

The PhOut12 allows software traditionally used for music to control motors.  The board can control up to 12 DC motors, solenoids, or relays, and up to four servos.  It also has a couple of inputs for sensors, pedals, or knobs.  This versatile board offers a lot of options for adding sound control to your art project.

Code and schematics are available at Bryan Jacobs Music.

You can purchase a kit of parts of fully assembled board on Tindie.

 

XtsTinyBasicPlus

Franck Galliat has developed XtsTinyBasicPlus to make it run on a Teensy ++ 2.0 and connect to a Cannon X-07 hand held computer.

XtsTinyBasicPlus is a fork of TinyBasic.  This version features support for an SSD1306 LCD screen, a uSD card reader, WiFi using the ESP8266 module, and 2 serial ports.  It can act as a little http server to execute an auto-script that outputs to a web browser.

Some additional information can be found on this blog page.

Chordboard

Ali Afshar (alialiali on the forum) built a chordboard – a nifty synth project that includes a drum sequencer.

Ali describes this labor or love project as playing the major keys of piano with the ability to change the key and mode.  It’s pretty easy to play and get a decent result.  It also features a drum sequencer, strings, chords, and other stuff.  The interface uses the oh so satisfying Cherry MX keys that have LEDs in them and a few pots to control things like tempo.
