CPX Headlamp

This is a circus playground express headlamp. This headlamp consists of a go pro head strap, a CPX, a battery, and a servo to make it work. This was created specifically for people who are outdoors a lot such as hikers and construction workers but it can be used by anyone. The headlamp also has a lid that is meant to cover the light when it is bright and it is meant to go up when it is dark.
