Lab Time
The ExpEYES kit brings the power of a professional science lab to a personal computer. If that computer is a Raspberry Pi, you'll get lots of great experiments at a very affordable price.

ExpEYES (Experiments for Young Engineers and Scientists) is a science and experimentation platform designed by the PHOENIX project, which forms part of the Inter-University Accelerator Centre (IUAC) in New Delhi, India [1]. ExpEYES is a hardware and software framework that lets you develop science and electronics experiments, demonstrations, and projects without getting too involved in the nitty-gritty details of electronics or computer programming. To sum up the ExpEYES Junior board in a sentence, it essentially converts any Windows PC, any Raspberry Pi, most Linux-powered devices, and most modern Android phones and tablets (with USB On-The-Go capability) into a portable science and electronics laboratory.
ExpEYES (Figure 1) provides several analog inputs/outputs with 12-bit resolution, in addition to a host of other features, like wave generation, capacitance measurement, and time interval measurement. The interface is accessible from Python using simple commands, and a Graphical User Interface (GUI) is already available for a large number of experiments on multiple operating systems. The kit also contains other accessories for building science experiments (Figure 2). The box titled "What's In the ExpEYES Junior Kit?" provides a summary of the contents.
The PHOENIX (Physics with Homemade 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 to use that equipment in their lesson plans. The design of ExpEYES combines the real-time measurement capability of microcontrollers with the ease and flexibility of the Python programming language for data analysis and visualization.
