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

4. Option 2: Creating a Printed Circuit Board with a INKJET Printer

Progress

Progress: We have learnt about the Oscillator and the Generator from reading the manuals. We understand how to operate those two machines. Also, we discussed about dividing the film into different squares by cutting and using silkscreen printing to make the different kind of patterns.

Problem: We haven't encountered any technical problems yet. However, I (Vivian) need to learn more about the basics of electrostatics like electric current, voltages, electrical fields, etc. 

Plan: We will continue what we discussed. Vivian will watch some Khan Academy videos to catch up the Physics part and Aaron will figure out how to apply the silkscreen printmaking process onto the film. 

Update Part 1/2

Progress:

Last thursday, we had a formal discussion with Mr. Lin about our project and what we need to do.

As long as electrostatic displays have existed, there has consistently been one major flaw. The way that electrostatic displays work is by sending an electric signal through the entire layer of conductive material. The way these prototypes have always worked around this is by sensing where the finger is and sending out the associated tactile signal for that location. But, we propose to make it so that we can have different cells each with a different tactile sensation.

This doesn’t have to be see-through. The technology already exists for a tactile-touch combo screen. We don’t have to redevelop that. Instead, we can focus on making a tactile device that is not visual (yet).

RE: Gantt Project

Feedback:

1. Your Gantt Chart shows that you have very limited understanding of the scope of your project, and how to approach your final goal. I strongly suggest that your team should find time to meet up with me ASAP to discuss your project scope, contents, and possible activities you can do to solve your problem.
2. You will have to redo your Gantt Chart based on our discussion.
