Experiments

A pool filter sand change led to a vacuum cleaner motor failure. The root cause was a carbon brush stuck inside its brass holder, preventing contact with the co…

Website update: custom AI chatbot integration and a practical comparison of Cursor, GitHub Copilot, and Claude Code during implementation.

Google deprecated Wear OS scripts; watch faces now use WFF. I built a custom phone + watch app to restore complications, weather APIs, and shortcuts.

I had mentioned in my last post that I would add AI to my project next. Here is an update on this project. The video below has the details. Under that is a summ…

In my last blog on the robotic lawn mower, I had indicated that I rewrote the old Python code using AI. Since then I have refactored the entire codebase and mad…

Replaced the handheld VX3 trigger with a phone-based controller for locked speed and full forward/reverse control — video walkthrough and takeaways.

Recently I decided to rewrite my microcontroller (Arduino/ESP32) project using AI assist, AKA vibe coding. I used Cursor IDE and Claude. What had taken about 6…

note: this is a 360 video. Open in the YouTube app and turn your phone around to see 360 view. Flying in the air like a bird has fascinated mankind forever. I s…

01-Apr-2023: Sometime ago I had posted a video of a 400w trolling motor on my paddle board. It's a good option for a leisurely stroll on the lake. The 24 v 20AH…

First successful RTK GPS test for the mobimower project — centimeter-level navigation after months of research and field experiments.

Minor setback. But chugging along.

Why Mobimower exists, the problems it solves, how the platform works, prototype evolution from 0.1 to 3.0, and the tools and technologies used in the build.

Upgraded the lawn mower from lead-acid to lithium — about 130 lbs vs 260 lbs, with roughly triple the usable range after research and a weekend install.

Most paramotor injuries occur from propeller strike. A safe hitch mount for ground start, testing, and warming up, with a wood frame to hold the motor while tra…

This weekend I converted an old bicycle to an electric bike. If you discount the research and prep time (removing old wheel and brake/gear levers) it took about…

Watch face and phone app to control an Android phone from Wear OS or Tizen — demo and explanation of how the flow works.

Thoughts on where generative AI is headed: learning from its surroundings, feedback loops when models train on their own output, and what that means for creator…

Demo of image processing in Python/OpenCV — angle math uses tangent (not sine) because tan values are available from the frame geometry.

Why am I talking about washers? Almost lost a wheel and could have ran the mower into the pool because the mower did not have any kind of washers at the wheel h…

Continuing from my battery replacement project from here , after a few days of installing the new lithium battery, I realized it needed a new cell. More details…

I am a fairly new paramotor pilot. And I know I am not the most athletic or aware person to do that. Knowing that I can make mistakes (and I have), I am working…

In this vlog I talk about how a trade off is made between the efficiency and power/efficacy of a machine. I discuss Aviation engine, automotive engines, and exp…

I started a new home project. I needed a motor with low RPM and high torque, to pull on both sides. I added two buttons to run the motor in either side instanta…
