Goal

Create a working EEG headset by following OpenBCI's open-source designs for the Ultracortex "Mark IV" EEG Headset.

Why not just buy it from OpenBCI? I want to learn about the process of building a hardware project from the BOM and designs. This project is also an excuse for me to buy lab equipment to play with at home.

What I learned

• Use DesignSpark to read and edit .pcb files
• Update embedded firmware with USB-to-Serial interface
• Calibrate a reflow oven using data collected in Excel
• Read electronic component datasheets
• Solder surface mount components using a reflow oven
• Perform short and continuity tests on PCBs
• How to use a 3D printer

Current State

The two bio-sensing boards (Cyton + Daisy) and bluetooth dongle have been successfully soldered and tested to the best of my ability. The headset frame has been printed and glued together.
