Assignment 1: Make your own flashlight

The assignment from Class 1 for Introduction to Fabrication, we were asked to create a simple flashlight.  Our teacher, Ben Light's, only requirements for the flashlight were:

  • It needs to be portable
  • It needs to create light

I immediately went to the junk shelf after class to see if I could get any inspiration and I found this small tin:

When I found this, I immediately became nostalgic and thought it might be fun to make this into a flashlight.

While searching on the internet, I found this great tutorial--- Mini MOD Monday: DIY LED Altoids Flashlight -- and decided I would use this video to guide me through the creation of the console tin flashlight.

The trickiest part of creating this flashlight was to drill the two holes.  I had to drill through two layers of tin, both at different angles.  

The other difficult part was knowing exactly the correct size to drill the holes for the components.  I started off drilling the holes with a smaller bit and worked my way up to the correct hole size. I ended up using 3 different size bits for this.
