The first production run for foc.us EEG Dev Kit is now entering the third week. At times it has felt like a Sisyphean feat but Monday always brings new optimism and it feels like we are nearly finished.
The active electrodes are custom cables with a 3.5mm 4 pin audio socket.
Each cable is soldered to two active electrode PCBs. Pin 1 is the shorter length, Pin 2 is the longer and pins 3 and 4 are 5v power lines.
This process is repeated by everyone on the small production line.
There are two PCBs inside the EEG Dev Kit. The main PCB as shown in a previous blog post and the "sockets" pcb shown above. The sockets PCB is relatively simple to assemble and test, so we let a Monkey do it.
The original estimated ship date was March. Obviously we failed to hit this date for a bunch of reasons, some good (extra functionality), some bad(under-estimating testing time).
We are thinking about what gift we can give to make up for these delays.
Further updates to follow.
