Solder each wire of your Pulse Sensor (Figure
L
)
to the respective wire of an aux cable: red to red
(power), black to black (ground), and purple to
white (signal).
For EDA sensing, the electrode cables already
have their own 2.5mm plugs (one wire connects
to power and one to signal). To connect the
electrodes, you only need to snap them onto the
snap cable heads, and then you can stick the
electrodes on your wrist when it’s time to sleep
(Figure
M
).
For the flex sensor, solder one lead to an aux
plug signal wire (white) and the other to ground
(black). Once you have the wires soldered to
the flex sensor, we recommend you wrap some
electrical tape around the base of the sensor
to give it some rigidity at the base (Figure
N
).
Another alternative is to use heat-shrink tubing.
6. MAKE IT WEARABLE
You can really attach this device to your hand
however you want to. The only necessities are
that the heart sensor stays on your fingertip, the
electrodes stay on the inside of your wrist, and
the flex sensor stays attached to your finger.
An earlier version of the Dormio used a glove
(Figure
O
), but then people complained their
hand was too hot while they slept.
A newer version uses simple velcro straps for
