Two-Day Workshops

Academy of Physics Teachers, Kerala, in association with several colleges, is organizing a series of Two-Day Workshops on ExpEYES. The schedule is HERE. The focus will be on hands-on training, to enable the participants perform experiments independantly.

The software is currently available for PCs and Android phones. The workshop will be conducted using Android phones and all the participants are expected to bring an Android phone with the SEELab app installed from Google play store. Click here to install Seelab 3

ExpEYES is an instrument that can be interfaced to the USB port of a computer or Android phone. It provides a set of Input/Output terminals that will act as test equipment like DC power supply, Function generator, Oscilloscope, Frequency counter, Capacitance meter etc. It also Also supports I2C sensor elements for measuring physical parameters like temperature, pressure, magnetic field etc. More details are HERE

Plan of the program is given below. Participants are advised to go through the material below before attending the program. Click on the links for the details of each activity. During hands-on sessions, two participants will be sharing one expEYES kit. Minimum 20 kits will be made available.

The time schedule given below need to be followed strictly to cover the listed topics.

Session 1 (10:15 AM - 11:15 AM)

Demonstration of five experiments selected from different branches of physics.

  1. Acceleration due to gravity from the Time of Flight of a falling body. This experiment is conceptually very simple. Click for more Details

  2. Acceleration due to gravity from the Period of Oscillation of a Rod Pendulum. Click for more Details

  3. Frequency Response of an active band pass filter, wired using n Op-amp. The frequency and phase responses are explored. Click for more Details

  4. Transistor Characteristics. Output characteristics of an NPN transistor in the CE configuration is plotted. Click for more Details

  5. Velocity of Sound. The velocity of sound can be obtained by measuring the wavelength directly, which is done by finding out the distance between two adjacent points having minimum and maximum pressure. Click for more Details OR generating Cooling curve Click for more Details.

Explanation of the Input/Output terminals is given on the main page. Introduction to the Oscilloscope GUI.

Session 2: Hands-on (11:15 AM - 1:00 PM)

The activities in this session will make the user familiar with the usage of the Input/output terminals of ExpEYES.

Session 3: Hands-on (2:00 PM - 3:30 PM)

Continuation of the previous session, covering several experiments to study the nature of alternating current and the behavior of LCR circuits, mostly corrresponding to the theory taught in 12th standard. For a brief description of the theory login a guest to this LMS.

Session 4: (3:45 PM - 4.45 PM) Programming ExpEYES using Python

Even though GUI programs are available for many experiments, programming ExpEYES gives a deeper understanding amd also enables the user to design new experiments. There are library functions to control/monitor the Input/Output terminals. Click Here for more details.

Python code for some experiments presented in Session 1 will be discussed.

Day 2:

Session 1: Hands-on (9:30 AM - 11:15 AM) B.Sc level Experiments

Most of the experiments in this section are part of the B.Sc syllabus. Conventional method requires DC power supply, oscilloscope, function generator and frequency counter to perform them. Experiments like studying the Transient Response of LCR circuits is difficult with conventional equipment. Due to this reason they are currently present only in the theory part. ExpEYES can be used to perform all these experiments.

Session 2. (11:30 AM - 1:00 PM) B.Sc level Experiments

Session 3 (2:00 PM - 3:30 PM)

Session 4. Conclusion and Feedback (3:45 to 4:30)
