During my co-op job at Cypress Semiconductor I was assigned the task of designing a demo unit to show off a new Cypress system solution.  The goal of the project was to create a small and attractive unit that could be used to demonstrate the technology to potential customers.  I developed the electrical and software components of the demo unit and designed an enclosure to show it off.

To create a compelling demo, I wanted to be able to control the Cypress solution from an Android phone.   I used a IOIO board to interface with the Cypress solution since it can connect easily to Android phones over Bluetooth.  I wired the IOIO to the Cypress solution and got them talking to one another using I2C.  I powered the system with a 9V battery and added a switch to turn it on and off.

I created an Android phone app using the Android SDK.  The app communicated with the IOIO board over bluetooth to control the Cypress solution and collect and display data from it.

I designed the enclosure in Solidworks and contracted a local rapid prototyping shop to CNC mill the parts and assemble them.
