how to mount or carry the Cyton + Daisy ?
I want to record my everyday activities. So, I'll be wearing the cap 12 hours each day for a few days.
One of the issues I'm trying to solve is an efficient way of carrying around the CytonDaisy board.
I noticed that when I touch the pins, it affects the signals. If I touch the chip on top, it triggers a spike in accelerometer data.
So, does anyone have a good way of carrying the board around without messing with the raw signals?

Ahmed, hi.
Can you clarify, you state: "...wearing the cap...". Are you referring to Ultracortex or the electrode cap, or headband or something else? For Ultracortex, the headset contains a mounting location for the board(s).

I'm using the electrode cap
With the electrode cap, you could 'clip' the Cyton to your shirt or shirt pocket as shown in the photo below. A wire is looped through two holes / standoffs of the Cyton. Then a small spring clamp grabs the shirt and Cyton.
(Excuse the somewhat blurry old image.) It's from this page on velcro saline sensors, with other photos of the setup.

Since cable motion can induce artifacts in the EEG, it's helpful to have some way to reduce that. In the example shown here, there is only a short amount of cable (coming off the headset) hanging behind the head. Enough to allow head movement. Then the cable(s) are clamped to the shirt collar with a Sears Craftsman small utility clamp.

There are also some Cyton cases mentioned elsewhere on the Forum. As well as the printable Cyton case which is part of Ultracortex.
One aspect of the gel based electrode caps, is that the gel liquidity may not last all day. As the water evaporates.
