Biohacking : All Day EEG Recording Tools

The good folks at Interaxon responsible for the Muse headband have teamed up with Smith Optics to create a beautiful EEG which you can wear all day long. The earlier version of the Muse Headband could be used in the same manner, but it is pretty obvious that you have strapped a bunch of sensors to your head and will draw a lot of attention when used in public. The LowDown Focus Brain Sensing Eyewear is a winner in terms of elegant design, weight, battery life and extensibility.

These glasses come with a lot of classes. Perhaps Interaxon decided that the previous app was not training people in the art of  meditation sufficiently. Whatever the reason these glasses require taking 3 courses with nearly a dozen step-by-step meditations in each one before letting you adjust all the settings. The Smith Focus app is loaded with tips and explanations for getting the most out of your brief meditations. However, for those of us who are interested in understanding more about our mental states through out the day there is another option.

Interaxon has recently released the MuseDirect App for iOS only. It is designed to work with all these Muse EEG products and does a great job of saving EEG data (locally, streamed or copied). MuseDirect was designed for researchers, artists, developers and health professionals. It is by far the easiest user interface and plug and play setup that I’ve experience with EEG. In the above graph (saved from a MuseDirect screenshot) you can see the blue alpha waves dominate during a brief meditation. MuseDirect allows for recording sessions of any duration and downloading of EEG data in FIF (MNE), CSV, EDF or JSON formats.

The real power of the Muse tools is the ability to record very specific attributes of the EEG experience. Using MuseDirect on the iPhone to stream data to any machine running MuseLab (Win|Lin|OSX) provides a way for multiple people in different locations to view realtime brainwave data.

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email to let us know about your post so we can blog it up here.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

Join 32,000+ makers on Adafruit’s Discord channels and be part of the community!

Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.

  1. I was really excited when I saw the muse headband … I was going to order it straight ahead but then I found their SDK does not work under Linux and the licence agreement is not much permissive (you can basically only test it and play with it but not use it for anything real)

  2. Muse was released in 2014 and still has not provided a Linux SDK. However, they have been good about making command line tools, OSC streaming and even supporting raspberry pi in their toolchain. It is a bummer to not see the SDK available and specific tools only coming out for certain platforms.
