i have been testing with this micro controller for quite a while and i noticed that the range finder calculator is very unstable when making it calculation for distance it is over shooting by 100,000 meters then down to 500 meters when the test motor is right in front of the two sonars you might need to consider remaking the range finder calculator to be more accurate :) cool build though

@GorilaMutila the long vertical line is the cursor. bearing is from 0 (left) to 360 (right)

Thanks a lot! Will tweak it right now!

Btw, the center line is always my heading, right?

@GorilaMutila the distance is the actual distance from center to center, not the gap between them. To make measurement easier, you can measure from the bottom of the bottom sonar, to the bottom of the top sonar. Point the compass in the same direction as the sonar, so normally the bow of the ship.

Keep in mind that the greater the distance between sonars, the better the rangefinding accuracy will be.

Sonar works great and it is pretty awesome having a waterfall display on stormworks. I have a few questions though: how do I calculate the distance between the sonars? Is it the gap between them? And how do I set the compass sensor? Do I orientate it towards the bow of my ship or towards the direction I'm setting my sonar station?

Congrats on this awesome little project! Very, very cool.

I sold a lung and my left leg for this sonar, And it was worth it every second, Thanks lima!

nice

@Cromoly, thanks for the explanation.
Mr_SmiLe, sorry for my mistake.

@Dark Spirit thanks for the kind words! What Mr_SmiLe is referring to is the name Odmev, which means Echo in Slovenian.

@Mr_SmiLe I don´t think it´s an active sonar, because only "listen" noisy objetcs around. It don´t "actively" emitts a sound (ping) to hit objects and create and echo to listen to.

I like the interface just because remembers the pasive sonar screens like the real ones in modern submarines. A very original work, congratulations.

The name for this sonar would be more appropriate for active sonar. 😉

I dont get completely how this actually is supposed to work could you maybe upload an example sonar station ?

noice sonar

Sold my liver and two children for a single Odmev-2, didn't regret it one bit.
