A web-based interface for CNC milling controller running Grbl, Smoothieware, or TinyG. It runs on a Raspberry Pi or a laptop computer that you have Node.js installed, connecting to the Arduino over a serial connection using a USB serial port, a Bluetooth serial module, or a Serial-to-WiFi module like XBee or USR-WIFI232-T.

GeigerLog is a combination of data logger, presenter, and analyzer, and now released as version 1.5.0 ! Based on Python (Version 3), it runs on Linux, Windows, Macs, Raspberry Pi, and other. Supports HiDPI screens. GeigerLog is WiFi enabled for servers and clients; it can be monitored by SmartPhone. Initially developed for Geiger counters, it is now a more universal tool, which equally well handles data like temperature, air-pressure, humidity, CO2. Continues to support GQ Electronic's GMC...

Expression parser of strings like sin(pi/4) is written in c++, javascript, java and php. It is also possible to create functions x0+2*sin(pi*x1) for further calculations.

Standard IT tools applied to SCADA/IoT (MongoDB, PostgreSQL/TimescaleDB,Node.js, C#, Golang, Grafana, etc.). MongoDB as the real-time core database, persistence layer, config store, SOE historian. Portability and interoperability over Linux, Windows, x86/64, ARM. Horizontal scalability, from a single computer to big clusters (MongoDB-sharding), Bare Metal, Docker containers, VM, cloud, or hybrid deployments. Unlimited tags, servers, and users.

A distributed network of sensors with a central data store, to record environmental data. Project goals include: * to serve as a teaching outlet for: ** sensor programming ** distributed data collecting ** web APIs ** database ** web UI for numerical data ** graphing data sensibly It also gives me some infotainment in new (to me) technologies, and as an excuse to scatter ever more Raspberry Pis around my home.

Researches have shown that immediate feedback can increase energy saving dramatically. YoMo aims to empower people using low-cost open hardware smart meters in their household. The metering system consists of a coordination unit, a raspberry pi, and several smart meters, arduino boards equipped with communication shields and our self-designed yomo metering shield. The smart meters are attached to household devices and monitor their energy consumption. The gathered data is timestamped...
