Analyzing Data Using EEGrunt

While looking for artifacts, we found out that the mystery band that's been showing up on our spectrograms are actually.... coherence bands!

EEGrunt and Spectrograms

Dan playing music during the Chord Test! He is so talented!

We had Dan play piano chords, Beethoven, and Requiem for a Dream while we record test subjects EEG.

Using GitHub, Patrick and Nicolas from the High Altitude Balloon project came and coded for us in Python so we could use EEGrunt to analyze the data collected to create graphs and spectrograms. 

Data recorded on OpenBCI..

...created into a spectrogram!

Mini Field Trip!

Dan, Jenny, and Sheron looking so fly in the electric car!

How awesome! I got to ride a bike AND drive a care for the first time, at the same time!

VR Google Experiment

Musical Brain Waves

Yesterday Alex, Dan, and Professor DiLauro went to the Ciccone Theater to use the Baby Grand piano. Dan is a great pianist, and played chords and compositions while Alex listened and was recorded.

Dan was also recorded while playing. 

Design and Manufacturing Event Field Trip!

Our EEG team went to the Design & Manufacturing Event NYC and the Javits Center. 

We had loads of fun! We mainly concentrated out time at MD&M booths, which is the 

Medical Design & Manufacturing East section. 

Professor DiLauro, Alex, Dan, Sana (me!), Jenny, and Sheron!

We were lucky enough to witness awesome technology at work, like die cut/press machines, Canon smart lenses, biomedical devices, large 3D printers, latex printers, ect. 

Sheron was so personable and was able to get a paid internship with Gibraltar Laboratories in Fairfield, NJ. GBL is a biotechnology, family owned a operated  provider of sterilization and analytical services to the biopharmaceutical, medical device, and related industries.

Congratulations Sheron!!!

This machine uses a die cut and plastic injection process to create 60 gallons of medical cups in 20 minutes!

Soldering, Flux, and a Little Luck

Today, Jonny was able to obtain flux and solder a 'Daisy Module', which will turn our 8-channel board into a 16-channel board. To do this, we had to solder on pin headers to connect both boards together.

Testing, 1..2...3!

Today, Jonny was able test OpenBCI using the headgear we set up yesterday. We are in the process of modifying the cap to fit with our new experiment. Our team decided to get Virtual Reality goggles and put test subjects in different situations while we record their brain waves using the cap.

Our goal is to install a miniSD card into the circuit board so we can do live recordings of the EEG waves. We are also in the process of downloading several Apps that we can use with the VR Goggles.

Building OpenBCI Headgear

Today, our team finished assembling the 3D printed cap. We stripped the input channel wires and then threaded them through the octabolts, which are bolt like pieces. Then, we connected and glued the octanuts and springs to the cap so the octabolts can securely attach.

Jenny is going to need a bigger cap...

Testing OpenBCI Software

Today, Jonny was able to tinker with the OpenBCI equipment and set up the software on one of our Alienware laptops. Since the 3D printer is still printing our custom EEG headpiece, we manually attached the metal electrodes with medical tape to Jonny's arm, earlobes, and head.

The team gathered around Jonny as he explains how the OpenBCI software is going to work.

Our goal is to have all of the 3D pieces for the EEG cap printed, as well as invest in 3D VR Goggles for our next experiment and a microSD card.
