Probably some georef code out there to make kap files with contour lines.
So i there a cheap arduino/esp/Pi powered portable depth sounder available anywhere? Could be really useful cruising.
I couldn't find any such depth sounder. So I try building my own. I tried using a cheap fishfinder transducer to work with Arduino. During this experiment, I tried also "normal" waterproof ultrasonic sound sensors for Arduino and they seem to work as well. Now I am testing different sensors and currently work on an RC boat with an Arduino / GPS / ultrasound sensor on board to collect data. You can check a video about testing the sensors on my Youtube: https://youtu.be/njDQKdZzGMI My idea is to have the RC Boat I can send out scouting unknown anchorages. Maybe I change the Arduino for an ESP32 so I can monitor the depth in real-time.
But when I am already collecting this data I would like to share it and make it available in the chart for everyone.
