We are developing a neuro-device to collect brainwaves as a headband with integrated electronics. This repository holds the PCB schematics and layouts for the Neurolab Hardware.

Goal and Roadmap

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.

neurolab-hardware's Issues

Improve PCB Layout

  • Current PCB layout is not optimized with spacing and placement. There is room for space saving and placement.
  • Silk screen labeling is required. This can be performed once the layout is fully optimized.

Re-add MIT License Info for former code contributions

In this PR 1a5150c the licence file of the code of Silver was taken out. It was licensed under MIT License. Please add info that code of Silver is under MIT License back to the repo.

Please also check if any other info of former contributors was removed and re-add it.

Find alternative ICs for AD7173 and OPA2111

AD7173 IC is the heart of the Neuro Lab device. But this IC costs nearly 17 USD. Do some research on finding a cheaper version with similar or close capacities to this IC and evaluate the possibility of a replacement.

Similarly, OPA2111 is in a DIP package. It has pins that needs to be soldered differently than the SMD ICs. This will affect the manufacturing. Find an alternative to this IC which is in SMD packaging.
