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.
