Blog Post #2: The building process

Day 1, November 22nd, 2018

Our group started to cut the wires with the wire cutter given and lights given to make a circuit for each of our floor plan. I needed two light bulbs on parallel circuit, so I connected it together wires. We did not brought and did not had much materials, so we worked on designing floor plan, and talked about how are we going to put the circuits on every room. Next day we all are going to bring all of the materials required and start making the rooms in the shoe box with some other boxes.

Day 2, November 23rd, 2018

We brought a lots of materials including the shoe box. Also, the teacher gave us more materials then last time. One person did the drawing the floor plan on the box, and the other two, including me, tried to make a parallel circuit. Also, we learned how the clips work as a switch. We pretty much finished making circuits, so on Sunday, we chose to meet and finish decorating and designing the house as much as we can, because we thought that we are not going to have enough time to finish in class time.

Day 3, November 25th, 18

We met in one of our group member’s house. We didn’t had the wire cutter, so we chose to work on the circuits tomorrow in class time. With styrofoams and some papers we had, we have made most of the furniture and some other decorations for the house. Tomorrow at school at lunch time and class time, we’re going to finish all of the works (finish touch with decorating and making circuits).

Blog Post #1: Design and Rationale

In my group, I am doing the front door and kitchen. I chose to do in parallel circuit with two switch, so the bulb at the front door and the bulb at the kitchen does not turn off at the same time Also, you can turn off or on only for the one of the lights.

  • Bulb at the kitchen is 3.5 ohms /  2.57 current / 23.13 power.
  • Bulb at the front door is 10 ohms / 0.9 current / 8.1 power.
