how to reduce noise from Bluetooth interface
======== ======== ======== ======== ======== ======== ======== ========
==================== end of assembled with Option A ============================================
in case all solder is ok as instruction then works.
connect 5V power to 5V pin ( Arduino pin name ), then check
followings voltage.
+12 V, - 12 V ( this will be max +- 5 % offset )
5 V external ref V ( Arduino pin name ).
SJ 7-R & SJ 8-R : offset Voltage 1.25 V.
AD 0 & AD 1 ( Arduino pin name ) : offset Voltage around 2.5 V ( this will be around +- 5 % offset ).
in case you have battery operated OSC then
connect it to input pin, then will have output
resolute to AD 0 & AD 1 pin.
use 0.1 Hz to 300 Hz OSC.
SW up position : 0.16 Hz .. 32 Hz
SW down position : 0.16 Hz .. 200 Hz
this frequency maybe +- 10 % difference.
see Option B setup :
http://www.psychiclab.net/IBVA/kit1-1.html
input resistance 1 K ohm to 1 M ohm and
p-p 5 µV to p-p 200 µV input to test.
OSC ground connect to GND.
connect OSC with resistance to CH1 + and CH1- input. then check output from AD 0.
connect OSC with resistance to CH2 + and CH2- input. then check output from AD 1.
check with Oscilloscope and/or after next step : construction, check with IBVA / BrainBay application.
this is one of idea for test amp noise from my instructables page.
http://www.instructables.com/id/open-brain-wave-interface-hardware-1/step10/amp-noise-test/
in case SJ6 and SJ7 open ( OFF ) then need to put two jumper
like this way.
then put OSC and resister instead of jumper can test electrode and skin contact condition.
