ML Baby Monitor Sleep Tracker

A machine learning web app to track our daughter's sleep routine.

Google SDM API

SQLAlchemy

This is a complete machine learning project from data collection to production. I first connected to the API for our Google Nest camera and collected thousands of training images. I manually categorizeed the images as "baby in crib" or "baby not in crib".
I then constructed a neural network and trained it with this data. This was a long, interative process as I recognized various weaknesses in the neural networks (e.g. shortcuts by recognizing lighting patterns), and would then collect additional data and modify training methods to improve the model.

The project was then bundled into a web app to provide:

• Database for recording baby presence every 10 minutes
• Aggregation of data into "bedtimes"
• Live video feed, with live inference from the latest model
• Visualization of bedtimes for the week
• Meta-project information
  • UI for saving data from the live feed
  • A page for each model containing its hyperparameter info and a visualization of its accuracy.
  • A view of all data with ability to correct its value

Pop It. Now.

Browser game for popping bubble wrap. Try it out.

TypeScript

React

Testing Library - React

This is a simple game built with React to pop bubbles as fast as you can. The timer starts as soon as you start popping, and the app keeps track of your best time.

Cowlitz County COVID Tracking

Bot for gathering COVID data and tweeting daily graphs.

Python

BeautifulSoup

Matplotlib

Twitter API

Early in the pandemic I grew frustrated with the lack of trended data available for Cowlitz County. So I wrote a script to scrape their website every day, normalize the data to account for reporting gaps, compute 7-day rolling averages, and tweet an updated graph of cases.
Official reporting is now improved, so this bot is no longer active.

Audible Picture Frame

Picture frame for playing a voicemail from a loved one.

Arduino

C++

My wife lost her grandmother unexpectedly, but was ecstatic to discover a voicemail from the previous year of her singing Happy Birthday.
To help that memory last, I integrated a touch sensor, speaker, Arduino Nano, and SD card reader into a picture frame.
When the photo is touched, the frame plays the voicemail.

IP-Locator

API to get information for your IP address. See more.

AWS Lambda

Python

This is a lightweight cloud-deployed API for capturing your public IP address and looking up the listed location. The API can serve a standalone HTML page for human consumption, or a JSON response for applications.
