OpenEEG screenshots

Hi all

We had a go at hooking up an OpenEEG board to some electrodes and got some measurements. The screengrabs are all of a 0.5 second time-frame:

1. Lots of activity on channel 2 - so much that it is clipping

2. Typical Output. Some mains hum visible (50Hz = 25 cycles in this 1/2 second time-frame)

3. This is without the right-leg driver ear-clip connected. Lots of mains hum!

4. Some very clear eeg activity on channel 2 (approx 9Hz)
