Week 3 Updates

Two main advancements were made in this week's work, which were:

• Developing a Bill of Materials (BOM) and placing orders for the needed parts
• Beginning the development of the Pip-Boy smartphone app (Android)

Further refinements, minor but plentiful, were added to the mental blueprint of the idea that will be taken into account when developing the wrist device and the smartphone application.

BOM Developments

By searching through online stores and available resources, a Bill of Materials was made, including prices as well as the purpose of each part and an online link to them. All the parts have been ordered, with some still on the way.

PARTS		PRICE ($)	PURPOSE
Arduino Nano		7.98	Single-board computer; heart of the device
Heartbeat sensor		21	To give BPM and IBI readings
Temperature Sensor		11.49	To give body temperature readings
Display (small)		9.99	Display; prioritizes size		Functionality
Display (touch)		15.86	Display; enables touch screen interaction		Optional Functionality
Velcro Strap		7.6	Strap; allows for easy modifications		Aesthetic
Rubber Wrist-strap		12.99	Looks tight
Battery		14.8	To power the device
Charger		9.51	To charge the battery and device
Breadboard + wires		12.99	For prototyping/connections
TOTAL:		124.21

Android App Developments

Using Android Studio and the very many sample codes and tutorials Google's Android Team provides, some fundamental progress was made in terms of developing this app. For example, code that can exchange data with Arduino processors through Bluetooth was written, and some UI features were built with regard to making a complete and interactive experience whilst using the app. There is ample progress left to be made, specifically with regard to testing and interpreting its data exchange with the Arduino processor on the Pip-Boy.
