Here is the finished prototype with an enclosure

The device in operation with a USB portable power supply

The electrodes will be connected to the female connectors located on the left side of the EEG device. Since this hardware uses a Bluetooth connection, it is fully portable. This also helps with the safety of this design, as it has absolutely no electrical connection to the 110V/220V mains for power.

In the future, a custom 3D printable case will be designed. But for now, I will focus on getting this platform up and running, as the software side of this project is where the real challenge lies.

This pretty much concludes the 1st revision hardware build for this project. It is now time to write some code for obtaining and processing the EEG data. In the next post, I will post the code for the ARM processor and measure the performance of this EEG Acquisition device.
