HEGduino: Measure real-time cerebral blood oxygen levels (all open source)

Uses infrared light sensing to determine changes in blood oxygen levels in the brain in real time. Use the device in less than ten minutes to learn how to directly change blood flow to your brain. Neurons do not store energy, so regional brain activity is closely related to changes in blood oxygenation, where healthy blood flow patterns are essential for high function and growth of the brain.

NeuroStimDuino: an open source neurostimulator for students, researchers, and enthusiasts interested in neuroscience

Neurostimulation involves the application of short electrical pulses to the surface of the skin to stimulate underlying nerves and muscles. In recent decades, neurostimulation has been used as part of functional electrical stimulation (FES) therapy to help restore movement to muscles in paralyzed limbs in stroke patients and people with spinal cord injuries. While conducting research in areas such as pain relief and sensory feedback, scientists also use neurostimulation to study the effects of electrical current on neurons. Historically, the delivery of neurostimulation has required the purchase of expensive research-grade equipment or costly, time-consuming custom hardware constructs. NeuroStimDuino provides an open source alternative in the form of an Arduino shield.

HEGduino V2: Cerebral blood map monitoring

Since the release of HEGduino V1, we have been working continuously for more than a year and a half to develop a compact, state-of-the-art open hardware solution for home NIR-HEG biofeedback. HEGduino V2 is an original design that brings you low-cost, intuitive home brain training and research-grade cerebral blood flow monitoring. This new device also allows us to incorporate heart rate variability (HRV) training and even monitor breathing and skin temperature. HEGduino V2 is comfortable. Easy-to-use headset with wireless operation and battery power. These components are breakout boards that allow you to remove them from the headset for easy patching or replacement.

FreeEEG32: Affordable, stackable, open source, 32-channel EEG

FreeEEG32 is a stackable, open source, 32-channel, 24-bit, sigma-delta, simultaneous sampling board designed to meet the needs of scientists and brain hackers who require high-quality, affordable research-grade equipment. We have been developing this EEG for many years as we worked to create the ultimate open source solution to expensive proprietary EEG technology. FreeEEG32 combines four 8-channel AD7771 ADCs with ultra-low noise (<0.22 μV measured) sources and references, all driven by the powerful STM32H7 ARM Cortex-M7, while handling pre-processing. It's sensitive enough to handle high-quality EEG data collection and more.
