ExpEYES: Python Powered Open Source Pocket Science Lab


ExpEYES is an Open Source Pocket Science Lab for developing science experiments, classroom demonstrations and a test equipment for electronics hobbyists. ExpEYES combines the real-time measurement capability of micro-controllers with the ease and flexibility of Python programming language for data analysis and visualization.


An understanding of science and technology is necessary in every students life. The main challenge in the field of science Education at a global level is the declining interest of students into science. Unfortunately the performance of a student is often measured by the ability to memorize than the real understanding. as a result most of them fail to apply what they learn in the classroom to the things they encounter in real life. Students also lose interest because of absence of appropriate motivation and also due to the of lack of equipment.

The key to combating this is the adoption of an inquiry-based, 'learn-by-doing' approach i.e. learning by exploring and experimenting. However, almost everywhere science is mostly taught from the textbooks without giving importance to experiments, partly due to lack of equipment. ExpEYES (Experiments for Young Engineers and Scientists) is the most affordable solution to this problem. ExpEYES brings the ability to perform experiments with reasonable accuracy, opens up an entirely new path for learning science.

With the objectives of developing affordable laboratory equipment and training science teachers, ExpEYES is from the PHOENIX project of Inter-University Accelerator Centre, New Delhi. It is an Open Hardware and Free Software framework for developing science experiments, classroom demonstrations and projects without getting in to the details of electronics or computer programming. It converts your PC into a portable science laboratory.

ExpEYES can be used to perform a large number of experiments. For example, the device can be used to study electromagnetic induction, interference of sound waves, Lissajous Figures, to measure gravity by time of flight, alongside many other applications. Concepts like Lissajous Figures and Electromagnetic induction are quite difficult for most students. ExpEYES allows the study of fast changing phenomena and is an effective tool for exploring electromagnetic phenomena and the laws of electromagnetic induction—namely, Faraday’s law and Lenz’s law. The ability to capture real-time graphs offers the important benifit for students to better visualize the associated phenomena and develop a deeper understanding of it.
