If you and want to explore further, the full workspace is linked above and always up to date with new experiments.
Search engines dont surface these repos well, so here is a single page that explains what each project does and why it exists. Everything below lives in Bitbucket with setup notes, code, and examples.
A WiFi-driven NTP display you can build for under $50 using an off-the-shelf microcontroller (Pi Pico 2W). It polls NTP directly, or can pull health data from Zabbix and Prometheus to show alerts and metrics on a compact screen. Ideal for home labs, server rooms, or classrooms that want a quick signal without opening dashboards.
A ready-to-use Zabbix template that ingests NOAA space weather data (KP index, solar wind, geomagnetic alerts) so operators can see upstream risks that affect radio and power systems. Includes items, triggers, and graphs to slot into existing monitoring without custom scripts.
This template pulls personal weather station data from Weather Underground and maps it into Zabbix items and triggers. Perfect for environmental monitoring around labs, garages, or homesteads where local conditions matter more than airport readings.
A small Python toolkit for TI Nspire calculators that teaches subnetting math. Students can calculate CIDR ranges, broadcast addresses, and usable hosts directly on the calculator, making networking exercises hands-on without a laptop.
An in-progress glow plug controller with afterglow timing for diesel engines. The goal is to handle the hard math and timing logic so DIY builders can focus on wiring and relays while keeping the engine happy.
