- ALL materials have been ordered. Vest is in locker
10/3 - Gillian continued work in lab: 1hour, 30 minutes
- Couldnt figure out how to install ssmpt on pi, so sent Jim an email
- Without ssmpt, cannot send email with IP address
- Looked into installing VNC, but Gillian doesn't have space on personal computer to install (if Kenneth and Andre do though, she can walk them through how to do so)
- Created GitHub for project, and cloned the repo to the pi
- Found code from project that Gillian tried to get to the pi, download failed, will try again later when she has more time
10/3 - Kenneth finished ordering all components: 30 minutes

10/4: Gillian continued work in the lab: 1 hour
- connected pi with filezilla
- having trouble cloning the github repo to pi, didn't want to spend too much time troubleshooting that so will do that later.
- wrote two python programs which can control 1) a blinking LED (blinking.py), and 2) a light (lightcontroller.py). I don't have the breadboard or an LED so I couldn't actually hook up the circuit, but the code should work! I commented the source at the top of both codes if Andre/Kenneth would like to reference that.
- I've been having trouble installing some of the packages of code, so I have a sinking feeling that something may be wrong there. I have attached a screenshot of the error message I get when I go to "sudo apt-get update"
10/5: "Basic circuits with the Pi: 2 hours 30 min"

10/10: Kenneth found other resources: 30 min
- Talked to his bother about the project and discussed a similar project that he had done lighting his band trumpet.
- His brother's project consisted of two series of LED light strip that are interactive: including a mode that increases the number of lights shining with the volume of the the environment around it.
- Following his approach to sound sensing and light interaction, we can have a good sense of direction.
- Andre began preliminary design for circuits in vest: 45 minutes
10/11: Gillian working in Lab: 3 hours
- Note from Gillian: Sorry I haven't put in much time this week, I had 3 midterms and so many other things going on. I will be in town on Monday and Tuesday of fall break, and plan on spending a lot of time in the lab making up for my lack of hours this week.
- Power supply for pi: 5V battery pack that supply 2A would be ideal. Kenneth said he had a battery pack so he is checking that would work.
- The light matrix required 5V and up to 4A to power. The pi cannot power the light matrix in itself because of high currents. How do we want to power the light matrix?
- the auxiliary LED light strips require 12V of battery
- pi: still having issues updating it. Issue was addressed as a wifi problem. I still cannot install ssmpt to send emails with the IP address. Hopefully will get to spend some time with Jim tomorrow troubleshooting this.
- Python code for potentiometer circuit is complete and in the "zestyfiles" folder on the pi.
- all of the python code from one of the libraries is on the pi, director /home/pi/lightshowpi. I'm hoping once we get the light matrix soldered to the pi, we can run these scripts to display things on the light matrix.
- Started working on block diagram, it's in the google drive.
- Started working on getting the AD converter working.
10/11: Kenneth working on the Block Diagram: 2 hours 30 min
