Dalek sensor system

This project was created for the Gold Coast Science fair. It is basically a proximity detector that fires an “Exterminate!” through the speaker and lights up the gun when an intruder comes in it’s way. It was the most popular exhibit at the fair and the next phase will be to make it move!

This project was also documented and entered into the Hackaday Prize

Firstly if you are too young to know what a Theremin is – head on over to the Wikipedia page to find out more. In a nutshell, the Theremin is a musical instrument that can be played without physical contact by the musician.

The original Theremins used radio antennas but our version is considerably simpler using a simple LDR (light dependent resistor) to detect how close your hand is and change the tone on the speaker accordingly. We also added a battery (using an old camera battery Рthese things last forever on Arduino  projects as they have very high mAh values) and an RGB Led for extra effect.
