Thanks to everyone who supported our first campaign for HEGduino v1. We’ve evolved the technology, and HEGduino v2 is state of the art. It provides much more consistent signal quality and allows for combined HEG and HRV training. You can check out our new crowdfunding campaign at https://crowdsupply.com/alaskit/hegduino-v2. Please consider backing the project and spreading the word!
