Like everyone, I was busy preparing the poster and myself for its presentation. Posters looked great. The Symposium was fast-paced! I didn’t have time to see the others as we all left quickly to enjoy what time is left of the summer. So… see everyone in September after school is back in session.
Also… Jimmy … Macromolecules are a a broad category of molecules that are often referred to as biomolecules in the Biology TEKS. The electrospray mass spec can provide the atomic mass for any macromolecule/biomolecule that can be linearized and contains ions. From my brief training, peptides can be injected directly into the instrument (see original post’s picture). However, other molecules such as carbohydrates and nucleic acids are often run thru tubing for a HPLC connected nearby the equipment. From my reading on the internet, the fatty acids in lipids can also be linearized and charged so they too can be analyzed.
I started this week by trying to build a program that would detect a face in a still picture. After much frustration, Yong helped me add another line of code to my Haar Cascade. This helped my face detection program work- next step would be face detection via the webcam feed.
Facial Detection Code Through Webcam Feed
Yong and Presentation
Yong, our mentor, came by on the first day of the week. He laid out a step-by-step guide to help us emulate distancePPG. The first step was ‘Thresholding’- which means to turn an image into a 2D array-so it displays in only two colors: black and white. I had to put a hold on my facial detection plan and move to thresholding. Yong has been helping throughout this week- we started using Slack to share our code-he has helped me consistently when I get stuck.

Tuesday and Trotting
By Tuesday, I completed thresholding and facial detection with a still image and with the webcam feed. I took a break to focus on NumPy; I followed a tutorial online to help me learn a bit more about NumPy. This helped me learn the basics of NumPy. I knew I would be working from home on Wednesday- so I took all my notes home.

Gifts on Friday
Allen brought us food and a Pulse Oximeter. I’ve been thinking my TeachEngineering and using an Adafruit Circuit Playground to build a visual thermometer. This might allow me to create a Maker Challenge and I would like to use the IB Design Cycle, which is very close to the Engineering Design Cycle on the website. It is still quite early, so I might change my mind. One of the obvious benefits is that my advanced students have been using the Adafruit Circuit Playground-so they will be comfortable in using it. I wrap-up this week contently, I’ve completed thresholding, face detection and I’m almost done with shape detection of a face-but it might be more complicated than it looks.
Pulse Oximeter- how we will collect the ‘ground truth’ reading for the heart rate, we will be comparing this to our distancePPG reading to check for accuracy.
