Week 5 Update

We have encountered two problems over the past week, but we are still on schedule for the most part.  The first problem we have run into is that the mask has been delivered for over a week now but we haven't gotten an email telling us to pick up our package. The second problem we have run into is that the electrodes never actually shipped. We called them up a few days ago wondering where the package was only to find out that they never shipped it by accident. They said that they would ship them overnight, so we should receive them soon. Schedule wise we are actually exactly where we want to be. We will be done with the electronic section this week and we will start on the mask portion this week.

Even with these problems we have still accomplished. We have made all the alligator clips necessary for the project, we have grounded the entire circuit, and we are still working on the code that ties everything together. We have the accelerometer working in MatLab, yet we are trying to filter it to get it to be more accurate than it is right now. We hope that by the end of Week 6 the accelerometer can be finished and be ready for testing while we put together the EOG portion of the circuit.

Now that all the parts have been delivered I can give a breakdown of how much we spent on the entire project.

• Electrodes - $15
• Mask - $10
• Circuit board - $5
• Batteries - $10
• Amplifiers - $10
• Wire/Alligator Clips/Resistors/Capacitors - Free
• Total - $50
