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...

This library implement RIMS controls for home brewers. For definition of a RIMS, see https://tinyurl.com/j3lyuyc For me, an Arduino micro controller + a LCD Keypad shield was cheaper and a lot more customizable than a commercial PID controller. So, with this library, a commercial PID controller is unnecessary. Automatic PID tuning toolkit is also included. Temperature can be read with a thermistor, a resistance temperature detector (RTD) or any custom temperature probe. ...

.... * Soil Moisure Sensors are responsible for sensing if the soil of irrigated flowers are wet or not. These sensors are attached to the Sensor Controller Module via slow speed I2C bus. The modules use 2-pin probes and drives them with 4 kHz square wave in order to avoid oxidating the probes. In my implementation I used these small water pumps from Conrad: http://www.conrad.hu/conrad.php?name=Products&pid=539090 The whole system is powered by a 12V / 4A SMPS.

pyhard2 is an object-oriented framework to help in the development of instrument drivers. pyhard2 is proposed as an alternative to LabVIEW. Emphasis is given on serial drivers but the framework can be used with any socket. The source also contains the implementation of a PID controller and a setpoint ramp generator. The instrument drivers may further be incorporated in a GUI, using, e.g. PyQt or PySide. Threading is automatically taken care of. Furthermore, generic GUI (called controllers) are provided and can be extended.

MashBerry is a Raspberry PI based beer-brewing controller. It is designed to automate the mashing-process for the homebrewer. MashBerry can be operated via a Web-interface or via a Display and an IR-remote. The temperature is controlled using a PID-controller, the temperature-measurement is done with a PT1000 or a Dallas 18B20. For power-control an external Solid-State-Relay is used.

Quiet Fan implements a control loop to set your CPU or motherboard fan speed. This means that it uses the lowest possible fan speed to keep a target temperature, and eliminates damaging hardware temperature oscillations.

This low cost project is a RC servo like position control of one or two geared motor(s) with a pot as angle feedback. You can send the arduino microcontroller a value from 0 to 1023 and the arduino will control the motor speed and direction to reach your target value. The PID algorithm will insure that the motor will not get into hold vibrations if the pot has some influences. This article will describe where you have to take attentions and what you have to setup to get the best results. The project will help you to connect any arduino motor shield or other H-Bridges to the controller because it is open source and the output pins can therefor be changed as you like. ...
