Python Emotiv, Render Demo - displaying limited data. #112

I'm still not sure whats going on here. I think the issue is similar to issue #77 the data stream appears limited or similar to having the signal pre-processed, as the signal does change if you flinch, but the lines are smoothed out, almost like its lost its resolution.

same as issue #77 if you shake the unit mildly, a lot of distortion appears.

this is a relatively new unit, purchased april of 2014.

I also note that the Testbench 1.5 isn't registering that the Dongle is connected, where a previous version worked just fine. The sample rate holds at N/A and asks to plug in a headset.

I will be happy to investigate further, even if it means dumping the devices eeprom, but perhaps theres a simpler way. Could it be the crypto key is now invalid?

Would welcome some suggestions.

Your likely seeing output from static electricity when shaking the unit. The sensors values are measured in microvolts so it wouldn't take much.
