Open Source wearable bio-sensor: TrueSense Kit

Quantified Self Apps & Tools

2 products have come to market for that type of application:

  1. http://www.moxymonitor.com/
  2. https://www.bsxinsight.com/

I guess nothing is impossible to the unrelenting mind.

I would like to put together a very simple, low-cost BCI kit for a workshop at a summer hacker camp (q.v. https://www.emfcamp.org/).

At present, the TrueSense sensors seem my best option.

I’m trying to work out whether I should try to connect them to:

  1. a smartphone. This provides a monitor and power supply. Could I connect the sensors directly, without the TrueSense module, and use the phone’s processor (to further cut costs)? There may also be software compatibility issues if I want workshop participants to be able to use whatever OS their phone has.

  2. an Arduino. This seems reasonably easy to connect (via ZigBee), but requires a separate power supply (and possibly a monitor).

  3. a Raspberry Pi Zero. This is less expensive than an Arduino, and running Linux allows OpenViBE. Against this, I’ve only seen ZigBee connections via Arduino shields, and we still need a power supply (and possibly a monitor). I assume that they’ll be back in stock soon.

If anyone had any thoughts - serious or casual - I’d be grateful to hear them.

Thank you,

Colin
