This was our last project of the year, and it was my favorite one. It was cool because we were given the instructions, but everyone had the opportunity to make it unique. For my board I based it around Mr. Stacks, my physics teacher, and the stories he's told us.
First, we had to design our board on Inkscape. I learned a few more tidbits such as tracing the bitmap so it could then be used in my design. Next, we had to laser cut our board with the laser cutter. After that, we had to line the holes with copper tape or aluminum foil. When we were done lining each hole with copper tape/aluminum foil, we connected the holes with strips of copper tape/aluminum foil in the back to compete the circuit. We then grabbed a battery holder, a wire, an LED, a resistor, a pair of tweezers, and a strip of velcro. We placed one side of the velcro where we wanted our battery holder to be and placed the other on the battery holder. After the battery holder was stuck to the board, we poked the LED through and soldered the red wire from the battery holder to a 100K resistor, then to the long leg of the LED. The other leg of the LED was soldered to anyplace where there was aluminum foil on the back. For the tweezers, we soldered a wire to the black wire of the battery holder to elongate it, and we wrapped it around our tweezers so that the end of the wire was touching. To secure it we wrapped a piece of electrical tape around it.
In conclusion, this was a multistep project, but I had fun through each step of it. This is my last project of middle school engineering, and I'm excited to move on to Design method 1 and 2 in high school.
