Mini Fume Extractor

These are the parts that we started out with on the first day. We later acquired an Altoids tin, a switch, and a battery snap connector.

This is the first circuit that we assembled. We later had to disassemble this circuit because it is a short circuit. The new circuit is not pictured.

Before cutting holes in the tin, we had to place all the components into the tin to ensure that it fit correctly.

Once we figured out where everything went, we then began to cut two square holes into the tin for the air to flow through. 

Once the holes were cut we simply glued a guard over the holes and fit everything into the box.
