Noise Machine

I want to make it absolutely clear that the example below is an ERP based BCI and not ready for ‘concert use’ yet. It can be made to work a bit, but any movement results in trials being discarded, i.e. you can only measure an ERP if you aren’t contaminating the signal with other stuff. I’ve been gating these trials out.

However, you can easily use an EEG device to detect spontaneous potentials, e.g. brain rhythms. This technique is well known and easy to do. I don’t think this is as interesting as using ERPs (although you can do things with meditation). But it’s fun to perform with.

I want to make this clear because there are people contacting me asking if the erp system is ready to be used and I keep having to politely say the same thing. NO, not yet. More time. more research. more effort. I have publicly performed using the device to measure spontaneous potentials, but as I’ve explained above, it’s very different stuff to the video below.
