      The aim of this project was to continue the work of the previous project “Developing a Network Storage Device Using a Single Board Computer” using the lessons learned to develop a new device for a different use case. This projects aim was to determine the viability of a portable storage solution that could be powered by batteries. The hardware was a key area of this as a balance needed to be found between performance and power consumption. After researching different hardware options the Raspberry Pi Zero W was selected for this project as it included features that were needed, such as Bluetooth and Wi-Fi, and used the same operating system as the original device and would support the same code. Bluetooth audio receiver capabilities were later added as a required feature. Due to the hardware selection an audio output needed to be added. This was done using a Hardware Attached on top, HAT, called the pHAT DAC this added a 3.5mm audio jack to the PI Zero W. The device was tested at varying locations to determine the how much interference factored into the user experience of the device. Multiple tests were run on different devices, due to the application used for testing the tests were only done on Windows devices.
