Weekly Progress

Week November 2 - November 8

We have talked about using the etching process and build a homemade PCB. We might have to put black sheets on the walls and the glass door to create a dark room. Hopefully, we will begin once we have all the materials.

Materials:
- transparent film shett
- photoframe
- driller (with a point that can make 1mm sq holes)
- film develope chemicals
- red light
- black sharpie

Weekly Progress Report

Week 2: October 26 - November 1

Progress

 1. We have set up our laboratory space in the classroom
 2. On Thursday, we have set up the circuit board and the oscilloscope and the signal generator.
 3. Vivian has finished reading Chapter 1- Electricity and a little bit on Chapter 2- Electronic Components

Problem

 1. The signals are displaying incorrectly on the generator. We used the multimeter to see if the voltage was 12.
 2. We believe that we may have short-circuited the ATX power supply. 
 3. We think that it is the components on the circuit board. We will have to modify the board by experimenting.
 4. Designing the pattern board - Each square needs to be at max 1mm square big (that's really tiny)

Plan

1. Figure out if we permanently broke the ATX power supply.

2. Take apart the components on the circuit board and look for issues. 

3.  Option 1: Etching
