Week 1: labs

Life is funny, 12 years ago during my a national mandatory service I was sent to an electronic technician training course. The military had a plan to take girls without electronic background and make them an expert in one month. It didn't go so well... long story short, I finished my service as a graphic designer. Now, 12 years later, I quit my job as a graphic designer and I'm learning electronics, hoping to become an expert.


Reading all the materials was overwhelming. I read the materials and didn't feel like I understood anything. Three things helped me understand a little better:

  1. Working with others and explaining to someone else

  2. This video that visualizes the way a circuit works very well (specifically the presentation of voltage as height):


3. Doing the labs. Once I had put every component on the breadboard, it all became visual and more clear, in particular the "bus" metaphor.


Lab: Setting Up A Breadboard

- First I organized all I needed (the Things You’ll Need photos really helped)


- I used wire with header, so I didn't need to cut them or strip them.

- Then I tried to imitate the circuits on the photos

(My first circuit!!!😱😱)




**Measuring the regulator helped me understand its purpose


Lab: Electronics



One more thing that helped me is making "mistakes" and trying to understand what is the problem. In that photo above the position of the LED closed the circuit in the first LED so the other LED didn't got voltage

Trying the circuit with a motor:


The Get Creative With Switches assignment:

- I know I would like to use my Maneki-neko doll, using the doll's hand as a switch.

- The next step was to understand how I want the switch to work. After I realized that the foil (conducting material) is that part of the switch that opens and closes the circuit, I tried to figure out how to make the contact with the foil match the position of the arm. I knew I needed to think how I'm doing both scenarios (opened/closed) with the doll.

- The video in the lab (https://vimeo.com/29026837) gave me the solution, I needed the wires in one scenario to touch the foil paper and in the other scenario to not (closed and opened circuit respectively). Here is the final circuit:
