When we think of input, we traditionally think of the best keyboards and mice. But what if our brain could be the input? Peeg Starting at $250, it’s a Brain-Computer-Interface (BCI) Raspberry Pi HAT. Ildar Lakmaturin It uses measurable biosignals as a means of control.

The measurable biosignals are the same as those used in electroencephalography (EEG), electromyography (EMG) and electrocardiography (ECG). Signals are detected using electrodes connected to a cap worn by the user. The signals are processed on a Raspberry Pi and can be used to visualize the signals using Python scripts and control projects such as robots and drones. The creator asked Ildar Rakhmatulin to explain why he created the project.
“Years ago, I decided to pursue a career in neuroscience. I wanted to control robots with my mind, but I couldn’t find a low-cost, open-source brain-computer interface (BCI). For this I made BCI.”
This first project suffered a chip shortage and the cost rose from $350 to $1000. This prompted Rakhmatulin to continue his research using his Raspberry Pi as a processing base.
PiEEG uses the HAT standard introduced in 2014 and the Raspberry Pi B+. The 40-pin GPIO connection uses the SPI connection between the Raspberry Pi and the ADS1299 analog-to-digital converter, and can measure up to 250 samples per second and per channel. Just learn to control biosignals and use them as events to control aspects of your project. Rakhmatulin shows how to control robots with blinks Using PiEEG. The robot in question is a toy mouse, but it could also be an expensive robotic arm or drone.
PiEEG is currently seeking support through Crowd Supply.and has raised $9,100 at the time of writing, beating its goal of $4,000. You can purchase the 4-channel model for $250 or the 8-channel model for $350. Please note that crowdfunding a project does not guarantee that you will receive a finished product. You believe in the project and want it to succeed. You are not purchasing a retail product.
