After making our three switches, we started a unit on making a switch, but a little more complicated! We learned information about the Thai soccer team and how one day their whole team went into a cave to play to celebrate a player’s birthday. However, it was the monsoon season, and soon it started to rain and the water level in the cave was slowly rising. The water was coming from the entrance, so the team kept on walking farther into the cave. They had been missing for a while, and they were really scared. Finally, divers found them, but there was a problem of how to get them out. The divers used flashlights to see in the dark. Now it was our turn to make flashlights that they would have used.
I decided to make a flashlight tilted at a 45 degree angle. It would have two pipes connected to two caps on each end. I started with cutting my pipes. I used a ruler to measure the length and marked it with a pencil, and then cut it with a saw.
After cutting my pipes, I began to work on my switch inside my flashlight. I got two black wires and one red wire, a light, a battery, and a switch. The battery was connected to the short black wire and the red wire. The short black wire connected to the switch, which was connected to the other black wire, which was connected to the light. Then the other end of the red wire was connected to the light, completing the switch. I had to solder all of these parts together, and make sure it worked (which it did!). Then, I put my switch inside my flashlight, and was ready to decorate the flashlight.
I decided I wanted my flashlight to be like a galaxy, so I took blue, purple, and black markers and got ready to color. I was able to sort of blend the colors, and from far away I think it looks pretty cool. It took me a while to color because I had a lot of white space and it was slow to blend different colors together, but eventually I finished and am proud of my work.
However, while I was coloring, I realized I need to take the switch out of the flashlight so that I wouldn’t color on the light or switch, so I tried opening it. All of a sudden, the switch broke, and I had to re-solder it back together, which was not fun. I decided to keep the switch out of the flashlight and wait until I was done.
This caused a problem later on, when I took my switch and flashlight out and later found the switch on the ground, broken (again!). I didn’t have time to fix it, so I asked a friend to help, and she was extremely kind and agreed to help me. Without her, I don’t know where I would be, so thanks so much Sophie!
After finishing all the parts, I put it together. I think it looks great. I am very proud of what I made (with Sophie’s help)!
