prototype 1

Arduino BT + RBG LED feedback + pi & phi crop circle Laser cutter body + cable and head pad electrode.

use original IBVA hardware's AMP parts.

open this transmitter unit.

Cut this parts from transmitter unit board.

use two of them put together on circuit board.

then put on it Arduino BT and Li-ion 3.7 V battery.

in front put SW and 6 pin connector to connect cable and head pad.

in back put battery and connector for charger.

one charge runs 4 hour continue operation time.

1: connect 5 V power to two of AMP parts DC-DC converter power input. it is from Arduino 5 V output pin.

2: connect AMP parts output ( 0..5V output) to Arduino Analog input 0 and 1.

3: connect two RGB LED to Arduino Digital output pin, 3, 5, 6, 9, 10, 11.

4: connect battery via Switch to Arduino BT power input connector.

5: need to use changer for charge Battery. can not use this device when change battery.

6: connect cable and head pad to 6 PIN input. need to make and/or buy this cable and head pad.

two RGB LED light ON by command from IBVA application BS switch serial command.

left and right brain for each LED, delta/theta:Green, Alpha:Blue, Beta:Red brain wave trigger LED.

one LED is top, other LED is side.

originally use as Arduino analogue output pin, 3, 5, 6, 9, 10, 11 for drive LED. but to do so cannot use timer interrupt function. so i change it to use as Digital output.

and serial command for control LED was use with IBVA application BS number command, but to do so speed problem happened. so i change it to simple one character command.

Battery charger connector.

with charger. one charge operate 4 hour continue.

Cable and head pad. need to put 3 electrode to head pad. this cable has ear clip for body ground. body ground use for reduce AC power noise from outside.
