Add additionl Instruments to PSLab Android

Many instruments have been improved and new ones implemented. A number of additional instruments are still high on the wishlist of many users including ph meter, magnetometer and a distance measurement tool. Users also want to build experiments using different instruments at the same time and we need a section to be implemented for this new functionality. The Android app has seen big improvements and exciting features have been implemented over the last year, including recording, export and mapping features. These features have not been implemented in all instruments yet and there is work left here. Some areas also need improvements in regards to speed which are related to slower provision of map APIs of OSM for example. Furthermore we need more professional features like the ability to schedule experiments and to run them in intervals. Also exporting in other formats like JSON and Matlab, syncing and backup features are important. Finally the configuration of PSLab and the setup of the PSLab device via WiFi or Bluetooth as a data logger while unconnected needs to be developed.

Required Features to be Developed:

  • Implement connect to device via Bluetooth or WiFi
  • Implement setup device with ESP and provide all info on required steps in detail

Set of PSLab experiments and walk through

PSLab is a project meant for experimentation, the lack of experiments and walkthroughs will prevent people in the community to get involved in the project. By creating new experiments and developing the necessary tools for it the student will enable other community members to understand the usefulness of PSLab and spark their interest. 

Develop Continuous Integration System Set Up and Develop Advanced Automated Tests to Maintain Quality of PSLab Apps

Quality of the software and hardware is very important in order to maintain the usability of the project. PSLab needs a Continuous Integration system that can help guarantee the quality of the software and as much of the hardware as possible. In this task the student will do a research on the possible CI systems that can be integrated with PSLab and its application. Then a full setup will be done and different unit tests will be integrated in order to keep the software from PSLab being continuously tested.

  • Confirmed Mentor: Marco A. Gutierrez
  • How to contact the mentor: [email protected]
  • Confirmed co-mentors: Wei Tat
  • Deliverables of the project: A CI system for the software applications of PSLab, should contain as many unit tests of the system as possible

Neurolab

The goal of the Neurolab project is to develop an easy to use open hardware measurement headset device for brain waves that can be plugged into an Android smartphone and a software application and enables us to understand our brains better.

Our brains communicate through neurotransmitters and their activity emits electricity. The neuroheadset measures that electricity on the skin of the forehead and the software processes the signal so that it can translated into a visual or auditory representation. The data that can be collected can be analysed to identify mental health, stress, relaxation and even diseases like Alzheimer.

Current devices in the medical industry are usually not accessible by doctors due to their high pricing. They are also complicated to use. The idea of the device is to integrate it into a headband and focus on signals that can be obtained through the frontal lobe.

A difference to existing projects like OpenBCI is that it will not be necessary to 3D print large headsets. Instead we are focusing on creating a device that collects as much data as possible through the forehead. To achieve this goal we are using high-grade sensors and flexible electronics.

Required Features to be Developed:

  • Implement a firmware for alternative ICs to AD7173 and OPA2111
  • Implement Neurolab visual feedback in Android app
  • Implement Neurolab audio feedback in Android app
  • Update Neurolab desktop app to using latest libraries and Java version
  • Provide Neurolab desktop packages for Linux, Windows and Mac
  • Automatically build desktop packages on each merged PR for all major platforms
