I’ve finished a new boat and have tested the autopilot, with mediocre results. First, the construction of the boat. As you can see, it’s a double hulled boat now, which adds stability at the expense of...
View ArticleAn arduino “case”: Part 2
A new Arduino/autopilot “case” was needed if I were to flip the container upside-down. This case is slightly larger than the old one, but it is more solid, durable, will work if flipped, and it also...
View ArticleRecent advancements and ideas on the autopilot
The autopilot is well on its way to controlling a real boat. I am now testing the autopilot on land and on water. One of my most recent modifications was the addition of LED indicators: The LED’s (from...
View ArticleFirst, Working, Autopilot Prototype
There were many problems with my previous autopilot, the biggest of which was lack of manual override. Since then, I’ve completely redesigned the circuit, code, and integrated the autopilot into a...
