Open Echo SONAR Project goes schwimming | Update | 200kHz Water Test | 250V Booster

Nice to see you moving along at such a pace! A library would be amazing and i have no doubt it will blow up interest in the topic

[@Neumi]

That's the plan!

[@Jeff_Gaudette]

Great update and progress! Keep going!

[@Neumi]

Thank you! Will do!

[@jakobriedel3725]

Very cool project! Its also alway fun to play around with Photo-Flash capacitors ;)

[@Neumi]

It sure is! Until you touch the wrong cables 😂

[@gomond1]

That's totally amazing , I was working on a similar project 20 years ago and gave up due to la lack of resources. I found the video a little difficult to follow as you were talking so fast.

[@Neumi]

Noted. Thanks for the feedback :)

[@zero2spearo]

Incredible work! Why do yo think there are so few open source projects like this one? Is "diy echosounding" just too niche?

[@Neumi]

@@zero2spearo thanks! But I‘d say its a bit niche because testing requires a lake or some body of water and a boat. Also the ICs were not that popular in the past and without them you’d need to build everything from scratch including a lot of filtering and LC circuits which can be hard to get right repeatable. The TUSS4470 manages all the complicated stuff and can be controlled from an Arduino.

What was going on at 2:15 ??

[@Neumi]

Eehm. Voice break? 😂

[@vovochen]

@@Neumi Naaah. I am honestly curious !!

[@Neumi]

@@vovochen Wait... you mean the echos? There seems to be a pole under water while I rotated the transducer (the two echo lines at around 100-120cm)

[@Cthippo1]

Please tell me a sidescan capability is coming. I have a need for an affordable deepwater sidescan unit for mapping shipwrecks.

[@Neumi]

@@Cthippo1 i‘m actually working on it, but it will take some time. I‘m currently searching for an affordable commercial sidescan transducer. Diy transducer would be cool too, but probably hard to manufacture.

[@Neumi]

Have you seen the last video? I used a KOGGER basic sidescan. They are very affordable and I‘m using one of them to build a dive sonar.

[@Cthippo1]

@Neumi That is another application I would love to see is a side imaging or live view equivalent capability that I could dive with. Visibility around here us about a foot for half the year swimming randomly in circles is not an efficient Search pattern.

[@Cthippo1]

@Neumi That's the challenge, isn't it. Something that works on the end of a 10 meter cord is no problem, but when you need something on the end of a 200 meter cord then the price seems to go up exponentially. There are a number of big wrecks in Puget Sound in that 40-150 meter range that are too deep for conventional diving, but may be accessible with ROV tech. Just being able to get good side scan images of then would be a huge improvement because even NOAAs multi beam gets pretty pixilated at those depths. Not sure where you are based out of, but if you are around here and need a boat to try out your designs on a known wreck I have a bunch

[@xingewen]

nice update but you speak a bit too fast this time

[@Neumi]

Sorry for that! Will keep that in mind for next video. Thanks for the feedback! :)
