Pocket Science Lab ExpEYES

Repository for additional applications and sensor plugins to perform experiments with ExpEYES using Pocket Science Lab.

This repository holds additional applications and sensor plugins to perform experiments with ExpEYES using Pocket Science Lab (PSLab). PSLab is a tiny pocket science lab that provides an array of equipment for doing science and engineering experiments. It can function like an oscilloscope, waveform generator, frequency counter, programmable voltage and current source and also as a data logger. ExpEYES is an Open Source Science experiments and data acquisition system for physics education and research. The website of PSLab is at https://pslab.io.

Buy

• You can get a Pocket Science Lab device from the FOSSASIA Shop.
• More resellers are listed on the PSLab website.

Communication

• The PSLab chat channel is on Gitter.
• Please also join us on the PSLab Mailing List.

Installation

1. Install ExpEYES

• You can install ExpEYES easily on any Linux machine. There are deb files available that we included in the repository. Please find details how to install ExpEYES in the Readme.md.

2. Steps to install experiments

• The software extension that are available in this repository in the folder /experiments can be installed as follows:
• Copy the programs in home folder
• ToDo: Create makefile for installing programs in ExpEYEs directory and make these experiments available in a dropdown menu of main GUI.

3. How to run experiments

For Experiments various sensors and experimental setups are required. Typical steps are:

• Connect ExpEYES to your PC/Laptop
• Run Expeyes from Education Menue. The main ExpEYES GUI will popup. Check whether the device is detected.
• Then close the ExpEYES GUI.
• Open the terminal and run the program for e.g.

~ $ python coupledpendulum.py

4. How to collect and save data

• In order to make the experiments useful you need to collect and save data.
• To Do: Describe here how to collect data and to save and use it.
