KeyNotes: A Play-Along Keyboard

Here’s one of my latest projects, still in development:  KeyNotes

KeyNotes: A full octave of Illuminated keys

KeyNotes: showing the full keyboard octave of 13 notes from C to C

KeyNotes is a illuminated keyboard that sports 13 notes that span one complete octave: from C, C#, D, D#, E, F, F#, G, G#, A, A#, B, and C.  Each key is connected to a micro-controller to sound and illuminate each note.

While still in development, the intention is that KeyNotes joins the other www.SENSE-i.ca products that are designed to offer users the opportunity to engage with their environment through self-guided proscriptive stimulation to assist in decreasing responsive behaviours. KeyNotes players will be encouraged to play short pre-programmed sequences of commonly recognised melodies through both sound and light prompts.

The size and shape of each of the keys is modeled on my 88-note Yamaha Clavinova and cut from 12mm thick HDPE. The “white” notes and cut from one piece, while the “black’ notes are made from a sandwich of two pieces.  Each key pivots on a common brass bar that runs from dide to side.

Each key activates a microswitch and is illuminated from below with a full-colour RGB LED. These LEDs are connected into one continuous ‘string’ that is controlled by the Arduino Nano.  The Arduino is responsible for sounding each note and to output key information to the MIDI output.

Neat, huh?

The SIMPLER SIMON: Update

Introducing “The SIMPLER SIMON”, a fun game for seniors based on the original “Simon” 70’s game.

Aimed primarily at the elderly and people with cognitive challenges, the current version of the SIMPLER SIMON sports three basic games – “Follow Me” (simple and blink), “Memory Pairs”, and “Memory Sequence”.

Large tactile buttons, vibrant bright colours and playful melodies make this an engaging game for all ages.

Here, the SIMPLER SIMON basic “Memory Sequence” game is being played.

Based on feedback from field testing, the latest revision of the SIMPLER SIMON includes more rounded and textured (numbered) buttons, and baffling to reduce light bleed between adjacent buttons. Additional software changes have increased the range of tones used for the buttons, provided longer intervals between successive game plays, and added the “Memory Pair” game.
