Brain Control Your Appliance

Brain Control Your Appliance, Sort Of. The package can sense biopotentials, and that lets you do things like change TV channels with a blink of the eye or a muscle gesture. That’s the gist of their project example on Instructables.

Since the NPG has an ESP32 onboard, it isn’t hard to see that coupling it to an IR transceiver would be all you need to control anything with an IR remote. The real problem is reading things like eye blinks. The simplest way to think of the Neuro PlayGround Lite is as a 3-channel instrumentation amplifier + ADC + ESP32-C6 radio, packaged for measuring very small biological voltages.

The same hardware can be used for EEG, EMG, ECG, or EOG, depending mainly on where you put the electrodes and how you filter/process the resulting signal. It is true that you can measure EEG, so maybe it is brain control if you can learn to control your EEG output. EMC for muscles or EOG for blinking is probably somewhat more practical.
