Python standard library only, headless CLI and Tk GUI — website · download.
🦈 P2_Wireshark_Dissector_and_P2_Scanner Tools and a technical reference for P2 ("Protocol II"), the Siemens APOGEE building-automation protocol over TCP: a Wireshark dissector, a read-only scanner, a virtual PXC panel to develop against, and a P2→BACnet/IP bridge — for owner-operators working with their own legacy equipment.
⚙️ PPCL Workbench IDE, linter, simulator and debugger for Siemens PPCL — the line-numbered control language APOGEE and PXC field panels run. 90 lint rules, each citing the manual page it comes from; a browser IDE with a live point database; and an equipment bench that drives a program against a simulated air handler with sensor lag, actuator stroke time and injectable faults. Zero dependencies, Python stdlib only — nothing leaves the machine — download.
📈 HVACTrend Read-only BACnet/IP trend logger, web trend viewer and rule-based alarms for building HVAC. Logs the points you pick every two minutes, charts years of history instantly, and sends equipment alarms (discharge air off setpoint, low duct static, a boiler enabled but not heating) to your phone. Never writes to a controller. Python, SQLite — download.
🌡️ CoolingTowerSim Physics-based browser simulator of a commercial building's condenser-water cooling loop. Animated process schematic, full tower-staging sequence of operations, and live power-draw KPIs. Single self-contained HTML file, calibrated against real BAS field trends — live demo.
💧 Wetbulb Real-time, pressure-corrected wet-bulb temperature by ZIP, city, or GPS — with a cooling-tower approach reference, a shade-WBGT estimate, a 24-hour trend plus next-24h forecast peak, and a fully offline manual psychrometric calculator — live demo.
📡 PingerPlot Continuous-traceroute network path monitor for Windows and Linux (MTR-style). Per-hop latency, packet loss, jitter, and MOS with live latency graphs, route changes, alerts and webhooks, and a world-map path view. Installer, portable zip or pipx, with signed updates. Pure Python standard library — zero dependencies, no admin needed in ICMP mode — website · download.
🛡️ NetSentinel Network monitor and intrusion detection for a Windows PC. Packet capture with process attribution, SNI and JA3/JA4 fingerprints from encrypted connections, Isolation Forest anomaly detection, beaconing detection, and rule-based detectors for scans, brute force, DNS tunnelling and exfiltration. Python — website · download.
💡 Light Beam Self-hosted messenger and hub for your own devices: text and files of any size between them, phone notifications on your PCs, ring a lost phone, wake or remote-control a PC, and a private family chat. Runs on your own computer, and your devices reach it through Tailscale — no accounts, no third-party cloud. Node.js, with a web app and optional Windows and Android apps.
🖨️ CTP500 Print Server Your own app for the CTP500 Bluetooth thermal printer: a Raspberry Pi print server, a web app for any phone or computer, an instant camera on the Adafruit MEMENTO, lithophanes for a 3D printer, and an HTTP API for Home Assistant and scripts. No account, no cloud. Python.
🎹 MPK Macro Studio Turns an Akai MPK mini IV into a macro controller for Windows, and reads the keyboard's presets over a SysEx protocol reverse-engineered for this project and documented in PROTOCOL.md. Pure standard-library Python, Tkinter.
🐟 Synapse Reef A neuroevolution lake in the browser. Eight fish species, each thinking with its own small recurrent neural network, evolve and learn to forage, school, hunt, flee and breed in a lake with seasons, weather, dissolved oxygen, a nutrient cycle, plankton and plants.
