Project Neurofeedback: Going a bit further with EEG hacking (Part 3 - smaller unit)

Remove the TGAM1 Board

(This step is optional – I just wanted to remove parts that are not actually used and free up space. If you do this then you also need too add a 3.3v regulator circuit to the power supply, same as I did)
Separate the TGAM1 Board from the main board in the Mindflex Headset. This reduces the size significantly – Bluetooth board will fit with room to spare.


  • Cut headers attaching boards
  • Desolder and remove cut header pins
  • Keep connections to (Header P1 connections on data-sheet)
    • Ground (electrode)
    • Reference (electrode)
    • EEG (electrode)
Adding a 3.3v regulator, with filter caps, to the power supply (3 x 1.5v AAA batteries in series).
3.3v regulator board (strip board)
  • linear voltage regulator
  • filter caps
