ExpEYES is a low-cost open source framework of computer hardware and software that provides a means to perform low-cost science experiments using computers. ExpEYES offers formats designed for students from high school on. Let’s take a look at what can be done with ExpEYES.
According to its Web site, ExpEYES is a tool for learning science through exploration and experimentation, It includes integrated an oscilloscope and a signal generator and is powered via USB. ExpEYES offers 12-bit analog resolution, accurate measurements and is physically compact, for easy relocation. The software for ExpEYES is written in Python, an open source programming language. The online manual presents 50 (yes, fifty!) experiments that users can duplicate and, perhaps tha coolest feature of all, others can be easily created and added to the list.
So, from where does this marvel of scientific exploration come? ExpEYES was developed by the PHOENIX project of Inter-University Accelerator Centre (IUAC) of New Delhi. The long-term goal of this project is to make the equipment and methods used in research available to the student community. In science, experiments are performed, data is collected and analyzed. Conclusions drawn. The difference offered by ExpEYEs is the fact that the equipment is affordable.
So, what kind of experiments can a burgeoning scientist perform with ExpEYES? According to the ExpEYES User’s Manual, users can conduct experiments involving electricity, magnetism, electronics, sound, mechanics, optics, heat and computer programming. In terms of electricity, young scientists can perform experiments involving, among many other topics, voltage measurement, water conductivity and AC circuit study. Regarding electricity and magnetism, possible experiments include creating a simple AC generator and making an electromagnet. Some of the other experiments include amplitude and frequency modulation (electronics), sound velocity, using a stroboscope and hardware communication.
As potentially enriching as ExpEYES sounds, it is just one of several open source technology products created as part of the PHOENIX Project. If you’re interested in learning more about this and other opportunities to cultivate the scientists and engineers in your school, you should check out the ExpEYES Web site. Your students will thank you through their creations, if not through their words.
Thanks to Ajith Kumar for his support, the contributions that he provided and for suggested modifications.
ExpEYES is available for Linux and Microsoft Windows. It is available in Canada and the UK.
