A few years ago, I had the idea to track my sourdough starter using computer vision. It was neat to monitor it this way, but it was fairly impractical to do for each feeding since it required setting up a camera, downloading the images, and doing some manual image cropping before running it through my analysis script. The analysis was also only done after the fact, and what I really wanted was something that could tell me when the starter was ready to be used (or fed), or, if I missed the window of opportunity, how long ago it peaked.

Professional photos from Justine Russo Photography. For readers of my blog, you’ll notice that I haven’t had any new content in the past year. For good reason though, as I got married in June! Aside from planning the proposal and wedding, I also had the lofty goal of designing and making my wife’s engagement ring. With this post, I’d like to share my quest in designing and 3D printing the ring, along with some *minor* mistakes I made.

Background: When a hard boiled egg is spun on a table, it rotates freely since the inside is completely solid. With a raw egg, the liquid yolk sloshes around and resists rotation. By using math and physics, we can analyze the rotational oscillation of an egg and determine the yolk consistency. “If it’s worth doing, it’s worth overdoing.” - Jaime Hyneman Objective: Design and build a device to determine how cooked a boiled egg is using non-invasive techniques.

Background: I decided to combine the two things that I love most: music and LEGO. This whole project took me about a month and a half, very on and off. I’m quite pleased with how the headphones turned out in the end, as they are sturdy enough to be tossed around in a bag. My favourite part is that I can take it apart any time to make repairs that may be needed on the go.
