Of course, if you want to support the project. I will be very happy. If I have such support, I will be able to purchase components for the prototype and try not to drown it. After that, the improved model will be published for the benefit of the community.

This is an underwater vehicle, with zero buoyancy. I mean, there are no active ballasts. Diving occurs simply by inertia and due to the thrust of the water jet drive.
Another feature of the design is the controlled thrust vector. To improve the performance, the mechanism is based on a spherical connector. 
Yes, I know, the signal will disappear under water, but it's for the best, it will float to the desired depth. A precautionary measure, so to speak. 
I will be glad if you ask me questions, I will answer.
In short, I haven't been able to make a prototype yet. I think I've ruined my relationship with a good person.
I decided to post this model anyway, I'll see how the community will meet it.

The model is raw, though I've been creating it for like a year. But we haven't been able to try it out yet. There is no 3D printer. And not much money. In general, play, enjoy.

The impeller has been subjected to multiple alterations. So far, there is such a thing as a compressor, but I can also make a classic one. I think the water cooling of the engine is also quite interesting.

The FPV camera is still just standing there as a possible option. But I think it's better to wait.

The battery is in a separate, waterproof case. For quick change and charging. Of course it is better to have several batteries. In this form, they can be carefully integrated into the device.
