A backyard feeder in Ontario, Canada, watched end-to-end by hardware and software I built and run at home. A camera catches each visitor; a vision pipeline figures out what it is and logs the sighting — with the species and the model’s confidence baked right into the photo. The two most recent are always up top: Common Grackle Northern Cardinal Warming up the feeder log… if nothing appears, the latest visitors are over at birdfeedercam.justinlaviolette.com. ...

A web app for the paint lab. Measure a target color with an X-Rite spectrophotometer, store it as CIE L*a*b*, and PaintMatcher returns the closest existing recipe — plus an adjustment suggestion when the measured color misses the target. Built on Flask + HTMX + SQLite. Closest-match ranking uses ΔE2000, the industry standard for paint and automotive finish work.

Player 2 is a computer opponent by default — press T on your turn to switch it to a second human for hotseat play. ...
