Learning from failed crowdfunded hardware projects: #2 Hardware issues & #3 Electronic issues
Understanding the limits and tolerances of the hardware is also another big matter. Important not only for efficiency, but also for user security.
Fortunately for us, we will be manufacturing our device with proven off-the-shelf components that work on safe electrical voltages. We decided to start right with the prototype, using OpenBCI ready-made electronics that have the best quality-to-price characteristics and a huge community of DIY successes.

Prototyping with a well-known platform has only advantaged for us. A big and active community of “biohackers”, a proven infrastructure, and an approach that goes to the same direction as we want (3D-printing the headset).
We are now actively experimenting with the minimum possible number of components needed to have a robust signal-recognition system, as well as expanding our team with mechanical/electronics engineers that should take care of the nuances that go beyond our own research. Meticulous testing and certification of the end device is obviously part of our plans.
