ExpEYES is from the PHOENIX project of Inter-University Accelerator Centre,New Delhi. 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 science laboratory. PHOENIX (Physics with Home-made Equipment and Innovative Experiments) project was started, in 2005 as a part of IUAC's outreach program, with the objectives of developing  affordable laboratory equipment and training teachers. Design of ExpEYES combines the real-time measurement capability of micro-controllers with the ease and flexibility  of 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. The hardware designs are open and royalty-free commercial production is allowed.
