It is a hardware & software framework for developing science experiments, demonstrations and projects without getting in to the details of electronics or computer programming. It converts your PC into a data acquisition and control hub for a science laboratory.
The PHOENIX (Physics with Home-made Equipment and Innovative Experiments) project was started, in 2005 as a part of IUAC’s outreach program, with the objective of developing affordable laboratory equipment and training teachers. The design of ExpEYES combines the real-time measurement capability of micro-controllers with the ease and flexibility of the Python programming language for data analysis and visualisation. It also functions as a test equipment for electronics hobbyists and engineering students. Software for all products from PHOENIX are distributed under GNU General Public License and the hardware designs are under CERN OHL.

ExpEYES software is written in Python and it should run on any computer having Python interpreter (version > 2.7) and Python Serial library. It is included in the Debian and Ubuntu (version > 13.04) GNU/Linux distributions.
The fastest way to get expEYES running on your PC is to boot your computer from a DVD or USB pendrive, prepared using the ISO image. The procedure to to this on MSWindows is explained here. Once you boot from the pen-drive, the Lubuntu desktop will appear. Start the expEYES program from the Applications->Science menu. Download the ISO images of the Live DVD. This ISO image is prepared from Lubuntu 14.04 and contains other educational resources also.
A simplified block diagram of ExpEYES Junior is shown in the figure. The sensor/control elements are connected to the micro-controller. The user programs uses the Python Library to communicate to the micro-controller, running a program, written in C and Assembler. The micro-controller performs the control/measurement operations and sends the result back to the PC. The job is divided according to the capabilities and strong points of each device. The micro-controller does all the real time measurements and pass on the results to the PC where Python code is used for processing and displaying the data.
