Mysterious

Hi guys,

In class we were given 6 cardboard boxes that when you spun a handle something happened. In each box something different happened such as a flag spinning, poping up and down, multiple things moving, ect. Without knowing how the boxes worked we had to draw our ideas. These types of boxes are called “mystery boxes” or “black boxes”.  Tomorrow we are beginning to build our own mystery boxes. I am building a kind I didn’t meton. The kind I am building has the thing on top, which is visible, move side to side and up and down at the same time. I haven’t built it yet but I know it will be a lot of fun!

The Insides Of My Flashlight

Hi guys,

As you may know lights don’t turn on and off by themselves there is electricity and circuits involved. This is a picture of the inside of my flashlight. You can see the battery and LED, The switch is on the side but blocked by the battery. To set up my circuit I attached the positive side of the LED to one side of the switch. Next I attached the other side of the switch to the positive side of the battery. Lastly I connected the negative side of the battery and the negative side of the LED to make my circuit!

From Then To Now (My Flashlight is Finished)

Hi,

I finally finished my flashlight. It was a lot of fun to make and I want to share with you how it turned out. This is my finished project. I decorated it so when I look at it I can be happy. I will talk about the circuit and prosess of building this in my next post. I didn’t end up adding the grip or strap because I was happy with the way it turned out. One of the things that I really like about my flashlight is where I placed the switch, if you havn’t figured it out yet that is the little black thing and it controls when the light is on and off. I like the placement of it because if you hold the flash light around the middle that is exactly where your

I am including this just to remind you of where I started from.

Seeing in the Dark

Hi guys,

I just wanted to share my diagram for our new project, flashlights! Our challenge is to make a waterproof flashlight that can fit in a 7.75 inch by 6 inch by 6.25 inch box with the lid closed. My flashlight is going to have a few special features. It will have a grip (Made from hot glue) and it will be able to stand. You might be wondering how it will stand. Well in you look closely at the bottom left corner there is a circle. That is a third leg at the elbow bend. I couldn’t draw it because the paper is flat. I will show you soon when the flashlight is done! I will tell you more about my flashlight the next time!

My Finished Switches

Hi Guys,

I finally finished the switches I have been talking about! These switches were inspired by self driving cars. A sensor on top of the car tells the car when to stop or turn depending on the objects in its way. We are going to use the switches we built to direct and imaginary car (one switch will say to turn right, one to turn left, and the third to completely stop to avoid things in its way). The switch on the far right is connected by pushing the  two pieces together. This closes the circuit and makes the light attached to it. For the switch in the middle you press down on the tinfoil to close the circuit. With the circuit on the left you take the popsicle stick that sticks out of the side and pull in to turn the wheel, and close the circuit. All of my switch are rebounding, meaning they return to the position they were originally in so the light only flashes on uinstead of staying on.

Solder Basketball

Hi again. I just wanted to show you a project I have been working on. It is a solder person. My solder person is made from brass wire and solder. The person is mainly made from the wire but all of the parts are held together with solder. Solder is a metal that you use a soldering iron to melt. First you put the soldering iron of the place you want the solder to go. After 15 seconds of holding it there you can touch the solder to the tip of the soldering iron. If you do it right then the solder will melt and connect the two pieces of wire. The solder is eaisily moldeable but strong. Whenever you put the soldering iron to the solder it will melt and be easy to change. This is a great way to make many things! If you do decide to made a solder person you can customize it by adding accessories. Remember to wear safety googles, always have a wet sponge, and not to touch the tip of the soldering iron.
