Yes! My copy of @BlueFoxBook has arrived weeks early. Almost all the work I’ve done with RE has been on x86, but very few devices around me still use it. Looks like it’s time for me to get more serious about doing the same on ARM :-)

The total backend cost is $0.04/month thanks to the free tier: 2M function invocations, 10GB data + 1TB of queries in BigQuery, free monitoring & alerts on missing metrics… and 4¢ for GCF container storage. Not having to deal with maintenance and upgrades is invaluable.

BigQuery provides full SQL support and works well for this simple use case. I started by exploring the data with SQL and then moved to Data Studio, which doesn’t require SQL in its chart builder but still supports it for custom queries or derived fields.

3 sensors: SCD41 (CO₂, temp, humidity), PMSA003I (PM 1.0/2.5/5.0 in µg/㎥, PM 0.3/0.5/1.0/2.5/10.0 count/L), MCP9808 (high-res temp: ±0.25℃). All wired with STEMMA QT/Qwiic, so no soldering! The LED matrix displays animations & scrolling text. The support base is 3D-printed.

Recent project: air quality station with temp, humidity, CO₂. Runs on a FeatherS2 Neo (ESP32-S2 240MHz, 2MB RAM, 4 MB Flash, WiFi) with CircuitPython. Metrics displayed on two 128×128 OLED screens and sent to a Google Cloud Function, saved in BigQuery, graphed with Data Studio.

Weekend project: I used OpenCV to pull the velocity/altitude/distance metrics for the launch of the James Webb Space Telescope, using NASA’s stream. Staging is clearly visible, and so is its initial rise, slight dip, and long push to higher altitude.

If I had stayed in this shop just one minute longer, it would have meant a long walk back home with my groceries. Only 3mm remain out of the 14mm shackle, and thankfully I still have my scooter. San Francisco never fails to live up to its reputation.

GitHub’s new Copilot tool is mind-blowing. I’ve had access for a few days and have seen it generate complex code with only the occasional mistake. In the screenshots below, I only typed a short comment and the greyed-out part is what I could insert automatically by pressing Tab.
