Their are three important steps to 3D printing. The first step is to create a design you can do this by starting out with a shape and editing it to you choice. The second step is for the computer to slice up your design so that it can tell how to print it. The last step is to print it. 3D printing has had a a huge impact on the world: there are toys, tools and many more objects made from 3D printing.
For homework, i watched a video on how in the early 1900’s they harvested wood. It is very different from now because they didn’t have machines. It seems like dangerous job back then. They had to use hands saws and hammers to cut down the trees. They also had ropes instead of machines or ladders to climb up.
Today in tech class our assignment is to write about something we have built. I have made jewelry, a ring, It wasn’t to hard to make it because I had help. It felt a little weird making something but it was fun! I don’t have it anymore but I wish I did. I really enjoyed building and would do it again.
In computer tech we had to create a music video using the coding app scratch. I looked at some of my classmates posts and really liked them. I really liked Sophie’s, this was nice to see theirs because it helped me know what to do for mine.
For the fourth quarter of the year I was required to do computer technology. I did not know a lot about coding because I had only done it once or twice. Our first assignment was to make a scratch project about myself. I thought about all of the things that I liked and created a project. This was not as bad as I had expected and turned out to be really fun.
Mr. Calvert had told our class that we had to create/design a flashlight in the situation of the Thailand caves. The design of flashlight had to be small enough to fit into a tight box. For my design I wanted to do a 90 degree angled pipe with a smaller 1inch pipe to transition into a cap on the other side was a plug here is a picture of my design.
In class, we talked about the Thailand football team. For one of the teammates birthday they went to explore the cave. While they were in the cave it started rain. The rain became heavy and soon the cave flooded. The football team did not know how to swim and they soon went farther and farther back into the cave now they were stuck. This is a dangerous mission. So once the family found out they were in the cave they called for help.
In class, we combined our knowledge on switches and circuits and created a game. This game was to have your three switches attached to a alligator clip attached to wire in the circuit. When the tinfoil touched each other the light/circuit went on. To make a game off of this you need 2 piles of cards when the cards are a certain amount of colors there is a certain switch you flip.
When we used our switches there was a circuit to make the LED light go on. In class we were learning how to make our own circuit. To make our own circuit yo have to have a breadboard that connects to a battery pack with alligator clips and wires that connect the tinfoil to the source of light. At the end of the LED light there are two legs one of the legs is long that it’s the positive leg the shorter one is the negative leg.
For my first switch I created a rubber band connected to card board with tin foil on it the rubber band was also connected to a stand created out of popsicle sticks. The card board would be able to move and have flexibility based on the rubber bands. When piece of cardboard with tinfoil touched a base with tinfoil, when you pressed them together a circuit is attached to it and an LED light goes one.
For my second switch I made a pipe cleaner through a straw, that way it could move back and forth a card board piece and when the end of the pipe cleaner (which had tin foil at the end of it) hit another platform of cardboard that had tin foil when they touch the LED light turns on.
For my third switch I created a cardboard platform glued onto that was another piece of cardboard, attached to that were to rubber bands connected to a stand made out of popsicle sticks. When I pushed one piece of cardboard down to the other one, they both had tin foil on them, the LED light turned on again.
It was very interesting creating all of these switches. I came towards some obstacles like getting a very bad hot glue bubble blistered burn or having to restart a switch but overall it was really a cool outcome.
