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.
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.
YugenFlow v2 is a compact, easy-to-use, low-power smart thermal sensor board that uses low-resolution thermal sensors to detect the presence of people and determine whether they are moving in a given direction. The sensor determines the direction along an axis, the physical meaning of which depends on how the sensor is mounted. YugenFlow does not require motion to detect presence, but can use it to determine orientation. The sensor can detect and "track" up to two people simultaneously from a distance of approximately 40 centimeters. It's also very fast.

Whether you're a design engineer, a hobbyist, or someone just starting to program MCUs, ATtiny Flasher can help you—without having to port your code to the target platform when you're done.
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.

ThunderScope is the first oscilloscope designed specifically for Thunderbolt, allowing live sample data to be streamed to your computer at over 1 GB/s. This design eliminates all limitations of traditional oscilloscopes by leveraging the powerful processing capabilities of modern devices. Measurements are made fast and easy, with cramped UIs replaced by multi-window layouts and support for modern accessibility features. Sample memory was increased from megabytes to gigabytes, and the fixed list of protocols and trigger types was replaced by an ever-expanding repo. ThunderScope is also open source, so you have complete control over your data from the moment you sample it. You can easily add your own custom features and benefit from new features built by the community.
