Copper Circuit Lab

The first two circuits I created were started in lab. The simple one didn’t take long – the most difficult thing I found was practicing looping the wire over and under so it would be conductive as possible.

It was also hard to learn how to successfully connect the copper wire to the LED. On this example, I had to put pressure on the negative side of the LED for it to work most of the time. But this was an issue I would fix later on.

For my first picture, I used a quote that I found during lab last week. I connected the positives and negatives together, then connected it like the first circuit.

I had to tape down the sides of the LEDs so it would light up properly. There must be pressure on the battery so I made the placement of the quote line up with the word light.

For my 3D card, I wanted to do origami but I set up the circuits first. Since there were three LEDs I had to plan it out for a while then connect the wires and LEDs. I connected the positives to negatives again, but it looked a lot less organized than my previous one.

The origami was pretty simple, but it took some planning to decide what size would fit properly on the size I had allotted. I ended up cutting a 6x6in piece of origami paper twice to make the right size. In the end, I made 24 pieces for all the flowers. Once I had made them all, I glued the sides together then taped the flower on the paper. They fit perfectly in the middle of the LEDs which is what I wanted from the beginning.

To finish, I cut another piece of paper and glued it over the battery, so there’s only a little pressure needed for it to light up.

It’s hard to get a picture with all the lights facing straight towards the camera, but they all properly lit – there were no troubles with the circuit on this one, so practice definitely helped.
