Between Sunday and this morning I was able to bring together everything I've built into a single experience.

This morning I was able to record a video using my web cam while also streaming my heart rate data from my heart rate monitor and stream data from the OpenBCI Ganglion. I was able to capture all this data while watching a 2min video. Data for an 8sec video clip I defined was captured.

Everything is looking good. There are 3 things I'd like to test next:
(1) Test the quality of the captured data

(2) Test the setup works for longer videos

(3) Test the setup works for more and longer video clips

I've been using Cursor to build this app. And it's incredible. But I have found myself feeling very frustrated using Agent mode with Claude 3.7. Claude often does things I never asked it to and when it undoes changes it sometimes undoes changes to a previous, unsuccessful change we had just tried out.

This morning I worked with Agent mode using Gemini 2.5 Pro.

It's incredible.

It's very thorough. It takes a bit longer to execute prompts and make code changes. But it's changes are thoughtful and intentional. It gathers context about the problem, makes a few attempts and very clearly prompts you to guide it with an issue it's having achieving your original prompt.

It's really nice to work with Gemini. Gemini 2.5 Pro has been great so far at coding and fixing things for me. While Claude 3.7 has been annoying and not "thoughtful" or intelligent enough.

I'm traveling this weekend. But I will bring all my equipment to continue testing and refining the app. I should start capturing EEG data for video-watching later this week. And hopefully, start capturing EEG data for movie-watching in 1 - 2 weeks. The more challenging part will be to find a place where I don't feel safe and where I could more strongly recreate the deep feelings of fear I tend to feel when I'm alone. At night. Watching a horror movie like The Conjuring or The Witch.

When there's someone else in my apartment, even if not in the same room, I don't feel scared. I feel safe. It's when I'm alone that my head starts to spin a little more and the horror movie feels more real.
