Week 19 (03/21/2021)

This week the team has been in constant communication with the Engineering Design Center at the Loyola Marymount University campus. The team currently has a request to 3-D print the EEG helmet to place the electrodes in. We are hoping that the helmet will be printed before March 31st.

The team has also developed two sets of codes for EEG brainwave data collection. One of the codes was written using C++ on the Arduino IDE that transitions through all the brainwave channels using two multiplexers. The longitudinal bipolar and transverse bipolar montages of the 10-20 system were used when designing the code. The other code was written in MATLAB which collects all the data that the C++ code has written into a text file and then assigns each of the data to their prospective channel.

THIS WEEK

Tyler

• Developed C++ code for channels throughout the multiplexers for data collection

• Soldered header pins to the multiplexers to integrate them into the EEG circuit.

Mark

• Developed C++ code for channels throughout the multiplexers for data collection

• Developed MATLAB code to collect data from a text file and assign the data appropriately to its collected channel

• Soldered header pins to the multiplexers to integrate them into the EEG circuit.

NEXT WEEK

Tyler

• Continue to collect data from the EEG circuit and perform any necessary circuit debugging

• Potentially put together the EEG helmet

• Connect the electrodes to the multiplexers

Mark

• Continue to edit MATLAB code for improvements

• Assist Tyler on data collection

• Digitally apply a high pass filter with MATLAB to remove data being collected from movement.

Memo: Dr. Hossein Asghari checked up on the team to inform them with the upcoming Easter Break campus will be closed. He informed Mark that he should work on analyzing any data that is collected over the Easter Break.
