Original Design
Original Design
This original design was based on a common toy xylophone. All the 3D models were done on Autodesk's Fusion 360.
Sensors on Bottom
Sensors on Bottom
Our first idea for the pressure sensors were to put them at the bottom of the keys, This is the 3D model for that design. As seen above, the sensor is directly underneath the first xylophone key.
Sensors on Top
Sensors on Top
We soon realized that for a pressure sensor to work, there needs to be pressure on both sides, so we decided to change the design such that the sensors were on top of the keys. This would allow the sensor to be activated by the mallet on top, and the key on the bottom.
Button
Button
We decided to put a button to the end of the xylophone design so as to add an extra aspect of the toy. The button's purpose was to switch the colors on the Xylumos.
Final Design
Final Design
Our final design was modified such that the pressure sensors were placed in between two identical keys, as seen by the layering of the keys. This design was ideal for manufacturing.
