Hey everybody,

After a long wait and over a year of development, we’re finally ready to show off the new and improved HEGduino V2! Enjoy easy-to-use biofeedback and join a growing community of brain trainers with our low-cost tools while helping us bring state-of-the-art biosensing tools to the masses!

We have a lot of exciting plans this year, including the ongoing expansion of our new web-based Brain-Computer Interface (BCI) platform at https://app.brainsatplay.com. Learn more about us at https://hegalpha.com.
