We really like the Adafruit Trellis keypad, and realized that it would be a great Monome. Then it occurred to me...my daughter loves blinking lights and music, how cool would it be to make her a Baby DJ Monome for playing her favorite songs!
So we started with the Trellis keypad, then added an Adafruit Wave Shield. We stacked it all on top of an Arduino Uno R3, We won't bore you with how to build these, just follow Adafruit's excellent tutorials for the Wave Shield and Trellis. Here is a quick video showing the innards:
Next we 3D printed a case using Pumping Station One's Makerbot. Adafruit has provided a nice guide on how to print a case for these. Ours did not turn out perfectly, but the result worked well for our initial prototype. Note we made our case a little taller than the Adafruit example since we had to also fit a Wave Shield.
Finally, we had to test our prototype on our favorite toddler. Turns out she loves it!
For the next iteration, we would like to incorporate a speaker and rechargeable batteries. It will make it a little bigger, but anyone with kids knows that wires hanging off will only cause problems down the road!
