My Doctor Told Me to Track My Blood Pressure. I'm Bad at It.

My doctor told me to track my blood pressure. I'm bad at it.

Not bad at taking readings (my wife got me a nice wrist cuff for that). Bad at the tracking part. Writing numbers down, opening an app, remembering to do it consistently. If there's friction, I just... don't.

So I built a system that removes the friction entirely.

A Raspberry Pi sits in my office. When I take a reading, the Pi automatically picks up the Bluetooth signal from the cuff, pulls the data, and pushes it to a self-hosted health tracker on my private network. No cloud. No app. No subscription. No writing anything down.

Put on cuff. Take reading. Done.

Here's the part that matters: I'm very technical, but I don't know Bluetooth protocols and I had zero interest in learning them. That's exactly the kind of wall that kills a project. You hit something outside your expertise, the momentum dies, and the thing never gets finished.

I used AI to reverse-engineer the protocol and write the daemon that handles the sync. What would've been a project-killing detour turned into a two-day build.

But what I keep coming back to: the Pi doesn't need AI to run. AI helped me build it, then got out of the way. The solution is just Python on a $35 computer, doing its job quietly every day.

That's the pattern more people should be stealing.
