The assignment for our first class is to build a flashlight that is both portable and able to light up.
Here is what I got in the end.

The following is my documentation for the process.

At first, I welded the switch with a LED light bulb and connected them to a 3 volts coin battery.

Basic circuit and original idea for my flashlight

Then I left my little circuit in my tool box for a week. A week later, when I was sitting by my bamboo curtain with the light shadowing on my face. I have a Beta2 idea for my flashlight.

It was really hard to cut the wood into such small pieces, especially when I was using band saw and caring about my fingers.

Use a clamp to fix the edge of the wood piece. Leave it a fix width so that every time the wood got cut through it would come out same width.

Here is what I got. A bunch of acrylic rods and some wood pieces

The next step is to glue them together. I use a glue that is able to combine wood and acrylic together. ( though it does not work so firm after I put them into clamp)

After that, I have to drill a accurate hole into a piece of wood to hold the switch. It was really hard. So I split it into 3 steps.

1. Drill four holes at each corner of the designed place.

And then I finally got to insert my switch into the board.

After that I glue some pieces of the wood and acrylic together and then came across another problem, which is how to hold the LED light bulb in between.

I cut a line into the wood piece side and insert the tiny led light legs into it. To hold it better, I used glue gun to stick them together.

In the end, I glued all the other parts together and finally got my own tiny flashlight.
