When I was told to make a flashlight, a bunch of fancy flashlight pictures which I collected online was flashing in my mind. Since I love everything with wood color or texture, I was going to make a woody flashlight. Therefore I picked some materials in the shop:
However, I forgot that professor hadn’t taught us how to use power machines cutting woods in smaller pieces. So I finally decided to make a “starter flashlight.”
The electrical circuit of a flashlight is easy, just connect a led and two aa batteries with electric wire, the LED would make light.
To make sure the light is strong enough, I soldered three LEDs together and finished other parts of the circuit with tap and soldering.
Next step is to make a body. I need two materials. One has to be transparent for light going through, and another should be opaque for covering the “ugly physical circuit.” Therefore, I choose bubble plastic paper and the first layer of cardboard.
Before making the body, the bubble plastic paper should be disposed to remove the additional bubble.
Additionally, I didn’t put a switch in the circuit. Instead，when I press the wire in the bottom, the circuit connected, LEDs shine; On the contrary, when I loosen the wire, circuit unconnected, LEDs darken.
Finally, I got my flashlight!
