The following components have been used to built the project:

FLORA Wearable Electronic Platform

FLORA is Adafruit's small and compact wearable electronic device platform. It uses Atmel MEGA3204 microcontroller. It weighs about 5grams and looks like a disc of 1.8 inch diameter. For this project I used the second version V2 module.

**FLORA Wearable Ultimate GPS Module **

It is a wearable GPS module from the Flora series which is easily compatible with the FLORA motherboard. It uses 22 tracking and 66 searching satellights with an update rate of 10Hz and racking sensitivity of -165 dBm.

FLORA Accelerometer/Compass Sensor

LSM303 is the accelerometer/compass module for the Flora series. Although it has accelerometer, for this project I have only used its compass feature.

NeoPixel Ring

NeoPixel ring is a pretty looking cascade of 16 RGB LEDs. Being 1.8 inch in diameter, it perfectly fits over the FLORA board. They are also available with various number of LEDs but I chose 16 LED ring because of its size.

LiPo Battery

A Lithium ion Polymer battery is used to power the circuit to function alone without being connected to the computer. The output voltage varies between 4.2V when charges to 3.7V constant.

LiPo Battery Charger

I used the LiPo charger to charge my LiPo battery. It is a small USB device which charges the battery simply by plugging it in the socket.

Tactile Switch

A 6mm push button tactile switch is used as on/off switch and to toggle between the modes.
