Finally, I have finished my flashlight. I decorated it, and assembled it. Now, I have started making a set of doll furniture, including a red and green popsicle stick table, gold-colored cardboard benches, a multi-colored sofa, and maybe even a gold and pink bed! I am also probably going to make 2 pipe-cleaner people to accommodate the furniture. In that case, I will make 2 beds! Anyway, this will be my last post, because tech is ending soon, but I will update this post as I finish my doll furniture. Any updates will be in a different color. Overall, I am so excited to finish this project, but also sad, because tech is ending soon. Bye!
In tech I finished my sketch. I cut, stripped, and soldered my circuit. I cut a PVC pipe for my my flashlight. Let me explain to you how I did this. First off, soldering the circuit. When I solder, I am melting metal together. This is strong bond, but will break if you don’t put enough solder on, or pull it apart. To solder, we wear safety glasses, and use a soldering stick, or a piece of wire, to get the solder going. You can’t apply to much, otherwise it will go into your battery, and you have to get a new one. Now, cutting the PVC pipe. To cut the PVC pipe, you use a saw. One partner holds the pipe so it won’t move, and the other one saws! Overall, I am so excited to finish my flashlight!
In tech we started to draw our flashlights! First I drew the 45˚ angle pipe that the light comes out of. Then I drew the tripod on the bottom, with all the caps. A little more on why I decided to design my flashlight the way I did. I figured that you would be able to stand it up, but also be able to carry it. I also drew my circuit. The light is coming out of the 45˚ angle pipe, and the switch is in the back. Overall, I am so excited to keep working on my flashlight!
Today in tech, we learned how to draw items to scale. We learned the scale we were working with. Our scale was that one square was .25”. We did a lot of practices, where we measured a PVC pipes and then drew them to scale. Then we started brainstorming our flashlight idea. I wanted to do a tripod on the bottom with a 45˚ angle pipe on top, with the light coming out from the 45˚ angle.
In tech, we made switches. I made a duct tape switch. A duct tape switch is when you put two pieces of cardboard side by side on a piece of duct tape with a small gap in between. Then, you put a little more tape so it is stronger. After that, cut two pieces of tinfoil, and put one on the first piece of cardboard, and one on the second. Finally, plug wires into the tinfoil, and close your switch. Te LED light attached to the wires should light up. If it does, your switch works! I also decorated mine with pom poms. Here is a picture of my switch…
In tech, I finished my pendant. I left off saying I was putting it together, right? Anyway, after I put my pieces together, I soldered. I was kind of scared, because The soldering iron gets up to 842˚ F, and I didn’t want to burn myself. It was really cool! There was liquid metal oozing out of the iron, but almost as soon as it hit air, it dried, and was not hot anymore!! Overall, I really liked doing this, and am proud of what I made.
In technology, we have been working on wire pendants. This basically means that we are making jewelry out of wires. This is our first real project! The first thing we did was brainstorm designs. Our designs had to have only 5 wires, because we are just beginning. We made 15 designs, all of them were different. Then we picked the one we wanted to make. I chose a simple sunset design. The second thing we did was we made our circles that we were going to put our design in. We did this by using a cylinder made out wood, to wrap them wire around and create a perfect circle. Then, we very tightly wrapped the remaining wire around the wire we didn’t touch before. Overall, I am super excited to continue working on this project!
In technology yesterday, we did an experiment about how effluvia (static electricity) moves a piece of tinfoil inside a jar. In the experiment, we rubbed a plastic stick on wool. This transferred the electrons from the wool to the plastic. Then you take the stick, and put it close to the rod attached to the tinfoil. Since the rod was also filled with electrons, the electrons in rod went to the tinfoil, since electrons don’t like each other. Then the tinfoil moved because the electrons were trying to get away from each other. Overall, I really liked this experiment!
In tech we played breakout. The object of the game was to unlock the box with the safety glasses in it. We had work as a team to find clues, and then decipher the clues to find out the code for the locks. Our group was at first mystified by the clues, but then, after a hint from Mr. Calvert, we understood the clues and began to read between the lines. When we finally got it open, we got started on the mystery box. And we got that open too! Overall, this was a really fun day in tech!
Our first day in tech, we learned about safety and what we are going to do in tech. We learned about the rules, safety precautions, and the different tools that we need to be careful around. We also learned about some cool units we are going to do. For example, circuits. We will do a whole unit abut circuits. Overall, I’m really excited to continue tech!
