Open Source C IoT Software

The Red Pitaya is a commercial, affordable FPGA board with fast analog inputs and outputs. This makes it useful for quantum optics experiments, in particular as a digital feedback controller for analog systems. Based on the open source software provided by the board manufacturer, PyRPL (Python RedPitaya Lockbox) implements many devices that are needed for optics experiments with the Red Pitaya. PyRPL implements various digital signal processing (DSP) modules (see features below). It allows to arbitrarily interconnect the available DSP modules and retrieve signal values on timescales below 1 ms. The graphical user interface (GUI) provides a realtime display of the various measurement instruments and allows the easy configuration of DSP signal chains and feedback controllers. At the highest abstraction level, arbitrary feedback sequences can be defined to fulfill tasks as complex as approaching and locking a resonance of a high-finesse Fabry-Perot cavity (tested up to finesse=100,000).

The C-GM Counter is a low cost (<50$) DIY Hardware & Firmware for building a Connected Geiger-Müller counter device to record beta-gamma radiation levels. The counter is the hardware part of the overall A-GM project aimed for providing a long-term continuous measurement of the radioactivity level. see also A-GM Manager at https://www.instructables.com/id/DIY-Radioactivity-Counter-IoT-and-Eco-system/ ** IMPORTANT ** : From v1.4, Arduino Nano require Optiboot bootloader to work, other boot crashes.

The solution GreenHop aims to perform energy and environmental (temperature, humidity, dew point and atmospheric pressure) monitoring of the Data Center server room, providing energy efficiency indicators through green metrics for Data Centers. The GreenHop solution is based on open source software and hardware. The approach of using open source solutions enables its deployment easier and independently of suppliers at the same time makes the solution scalable to the needs of each organization. Thus, we aim to provide ambiental monitoring of the Data Center server room while we keep the system to be customizable to implement and replicate.

JSTx is used for displaying overlay graphics and text on top of a Philips television, changing channels, receiving remote control keys and changing television display modes. It is a command line utility to execute jointSPACE commands on a device that supports the jointSPACE protocol for Philips televisions (see http://jointspace.sourceforge.net for details on jointSPACE, which is based on DirectFB). It is used in various home automation/internet-of-things projects. There are three versions: 0.23 for 2009/2010 Philips televisions (xxx5 en xxx4 series), 0.24 for 2011-2012 televisions (xxx6-xxx7) and 0.24_2013 for 2013-2014 televisions (xxx8-xxx9 (only non-Android)). New Android sets (2014+) do not come with Jointspace and are not supported. It works on Linux operating systems. A Raspberry-Pi version is also available.

TOISWITCH is a general-Purpose multi I/O-Server for ESP8266. Its build as an easy-to-use Web-GUI-based server for a range of smart home devices. Currently it supports the following types of devices -Power plugs and Power strips incl power measurement -Multicolor (RGB/RGBW/RGBWW) LED lamps incl gamma correction -Switches -Dimmers -Motion detectors -Motor controls -Sensors It has an easy-to-use web-interface to control the devices and configure them. It supports powerful profiles. to combine inputs and outputs. It also supports MQTT including MQTTs as publisher and subscriber to make it possible to combine multiple devices and to create complete scenes with just one click (i.e. to switch on lights within the whole flat). Via MQTT its also possible to integrate the devices within a existiong smart home environment or control them via internet. Its also possible to create timeplans and set short-time-timers. Updates can be easily done within the web interface

The aim of the project is a lightweight intrusion detection library for embedded devices which supports MSP430 and ARM Cortex based devices. Features include DSP/SIMD support, IoT and embedded protocols, distributed operation, event and history management, tool supported configuration and visualization. There is a Java port that supports less features.
