Portfolio #4

So as you might know from my last blog post I finished my soldering piece, and now I will  be working on switches.

The way that our switches are supposed to work is by putting tinfoil against tinfoil and connecting it to wires and the goal is to light up a light. We are supposed to make three switches, but it’s ok if we don’t make them by the end of the unit, but we can only make three switches max.

My first switch was something pretty simple. What I needed to make this switch was cardboard, a rubber band, a popsicle stick, and most importantly… tinfoil! I started by using something called a jigsaw. Now you may be wondering what this is… This is a machine that allows you to cut straight lines, make a perfect circle, and make the perfect cut for anything your trying to cut from cardboard.

So I started by using the jigsaw to cut a rectangular piece of cardboard, a very small square piece of cardboard, and an average size square. Then I hot glued the very small cardboard square onto the middle of the bigger rectangular piece of cardboard, and I also hot glued the other square onto the edge of the cardboard rectangle. After that I  hot glued the rubber band under the cardboard rectangle, and hot glued the other half of the rubber band to the  popsicle stick. Then the rest was simple, I Taped tin foil on the bottom edge of the popsicle stick, and taped tinfoil to the square that was on the edge of the rectangle.

Once I was done with that it was Time to test my switch! To test it I attached one red wire to the square with tinfoil, then I attached a  black wire to the side of my popsicle with the tinfoil. And then  I put the popsicle on top of the very small square that was in the middle of the rectangle and pressed the popsicle against the tinfoil square to light up the light! And it worked!

Here’s the picture of the jigsaw…
