The build instructions have been completed and can be viewed here or at the root of this repository. The project for this semester has now been completed on time and within budget.
Today, the project is presented to the class. The Power Point can be found here.
The schedule has been followed accordingly for this week. I have finished the presentation on time and am on track to complete my build instructions by the end of the term.
The budget has been updated to reflect the final changes of each indavidual item being acquired.
The schematic can be found here.
After getting my case laser cut, some glaring problems were observed. While I had resized the sides/top/bottom to accommodate the addition of the LCD display, I had neglected to take in to account that the indiavidual slots on each peice would be moved as well. As a result, each piece did not fit together and the case could not be constructed. Below is a picture of my second option, that being to use the original case the Raspberry Pi came with and attach the screen to the top. In the future a cover will be added to the top of the device in order to protect the electronic components inside.
The schedule has been followed accordingly for this week. I was able to succesfuly design and send in my schematic to the prototype lab for cutting. After having to use my backup plan for the case, I was able to remain on schedule.
The budget has not been changed as of this date.
This week I received my updated version 2 of the PCB now with the correct number of ports and connections. I soldered the vias together, and attached two pin headers for both the GPIO pins on the Pi and the 6 pins for my LCD screen. These headers are being used so the devices aren't permanently soldered to the board and PCB. Below are two images of the PCB after soldering (front and back).
After solding and connecting both the PCB and the LCD to the Pi I was able to compile a simple C script to read in a string from the terminal and write it to the LCD. The below images show the script running.
After having to make up the time lost redesigning and soldering a new PCB I have returned to the proper place in the schedule and remain on track to complete this project by December 11th.
The budget has not been changed as of this date.
As I began soldering the vias together I noticed that I didn’t account for the GND pin not being placed adjacent to the CLK pin on the display. As such, I was required to move the ground connection on the PCB over one port. Also, I reconfigured the total number of ports on the PCB to match the amount of pins that the display has. In other words I added a sixth port to account for the SS pin. The SS pin and the SDA pin will be left open. The files were sent to the Prototype Lab and the PCB should be constructed by the 8th.
As I was unable to complete the soldering task laid out in the schedule by the end of this week's lab period I will now be completing it on my own time by the end of day on November 9th. This will keep me on track for next week when we will be deomstrating our sensors/effectors.

I am on schedule as it is laid out here. The PCB Design has been completed and my Gerber files have been sent in for production.

- Pin01(3.3V) = VCC
- Pin03(BCM 2 Data) = DATA
- Pin05(BCM 3 Clock) = CLK
- Pin06(Ground) = GND
Initially I ran in to an issue of connecting to the wrong ground and power pins on my Pi. I switched from 5V to 3v3 and adjusted the ground so it was on a closer pin.

I am on schedule as it is laid out here. Breadboarding was to be done by the 23rd, and it has been completed on time.
The budget has not been changed as of this date. Solder has been borrowed from the Prototype Lab and the acrylic casing will be acquired on the date laid out in the schedule.
