Built a tool to help my daughter prep for her 10th-grade national exams and 12th-grade matriculation exams -and, without her knowing, set a little trap to catch AI use. Well, it sprang sooner than expected 😂

Image diff tool

I occasionally need to compare two versions of a diagram or a screenshot to see what actually changed. There are free websites for this, but they all want the images uploaded to their server, and the diffs they produce are…

Speed camera watchdog for the Tesla

Added a speed camera watchdog for the Tesla using live Waze report-scraped data. Implemented same-street filtering to drop false positives from nearby roads. Still far from ideal. Don't ask why I needed this.

OpenClaw on a cloud VPS

Just finished setting up OpenClaw on a cloud VPS. I'll be chatting with it over a private Discord server/channel. I've set it to use anthropic/claude-opus-4-6, so it should be quite powerful. Fun times ahead. OpenClaw is burning through tokens like crazy. Had to revert to more basic models after shelling out $35 in three hours.…

Frigate performance optimization using Gemini

Impressive Frigate performance optimization using Gemini. My Raspberry Pi 5 + Coral TPU setup handling 8 cameras has seen a 38% drop in CPU usage, despite increasing the detection frame rate from 4 to 5. Gemini made several smart suggestions, including generating a shell script to ffprobe camera streams and determine their characteristics, splitting and…
TeslaMate indoor and underground garage position tracking

I've been running TeslaMate for about a month and am quite impressed by the detailed metrics it collects, especially the precise indoor and underground garage position tracking. I assume it's based on vehicle speed and wheel direction.
