The goal of PSLab is to create an Open Source hardware device (open on all layers) that can be used for experiments by teachers, students and citizen scientists. Our tiny pocket lab provides an array of sensors for doing science and engineering experiments. It provides functions of numerous measurement devices including an oscilloscope, a waveform generator, a frequency counter, a programmable voltage, current source and as a data logger.
We are developing the experiments starting on the hardware to libraries and user interfaces for desktop PCs and Android apps for smartphones. The PSLab project is inspired by the work of the Open Science Hardware community and the ExpEYES project.
The desktop applications for the control and measurement functions are written in Python programming language. Pyqtgraph is used for plotting library. A variety of experiments can be performed using GUI applications written in python. PSLab is interfaced and powered by USB port of the computer.
PSLab is equipped with an array of useful control and measurement tools. This tiny but powerful Pocket Science Lab enables you to perform various experiments and study a wide range of phenomena.
Some of the important applications of PSLab are mentioned below...
For desktop PCs a Python communication library and PyQt4 based graphic user interfaces are available for a number of experiments, that make PSLab a must have tool for programmers, hobbyists, science and engineering teachers and students.Learn More...
The following code repositories of PSLab are available.
To install PSLab for Desktop PCs on Debian based Gnu/Linux system, the following dependencies must be installed.
Dependencies ============ PyQt 4.7+, PySide, or PyQt5 python 2.6, 2.7, or 3.x NumPy, Scipy pyqt4-dev-tools #for pyuic4 Pyqtgraph #Plotting library pyopengl and qt-opengl #for 3D graphics iPython-qtconsole #optional
2. pslabTo install, cd into the directories
$ cd <SOURCE_DIR>and run the following (for both the repos)
$ sudo make clean
$ sudo make
$ sudo make installNow you are ready with the PSLab software on your machine :) For the main GUI (Control panel), you can run Experiments from the terminal.

Connecting a PC to PSLab is as simple and straight forward as this...
>>> from PSL import sciencelab >>> I = sciencelab.connect() #Returns None if device isn't found # An example function that measures voltage present at the specified analog input >>> print I.get_average_voltage('CH1')
Various sensors can be connected to PSLab and data can be fetched with a simple python code as shown below...
>>> from PSL.SENSORS import HMC5883L #A 3-axis magnetometer >>> M = HMC5883L.connect() >>> Gx,Gy,Gz = M.getRaw()
>>> from pylab import * >>> from PSL import sciencelab >>> I=sciencelab.connect() >>> I.set_gain('CH1', 3) # set input CH1 to +/-4V range >>> I.set_sine1(1000) # generate 1kHz sine wave on output W1 >>> x,y = I.capture1('CH1', 1000, 10) # digitize CH1 1000 times, with 10 usec interval >>> plot(x,y) >>> show()The output of the program is here...

PSLab is aimed at high-school science teachers and students, who may or may-not be familiar with the computer programming. For such users it is difficult to design or develop new experiments on their own. They may also find it difficult to fetch the data and plot required graphs, if a ready-made GUI is not available for that particular experiment.
To enable users to quickly design a simple experiment for studying various phenomena, we have developed a simple Experiment Designer GUI. This incorporates few controls, read-back elements and easy functions to select parameters and plot graphs. The next step on our roadmap is to offer an Android app that enables students and teachers to conduct experiments on their smartphone.Read More...
