Plz make a detailed how to make vid and send it to me!!!!!!! I would like to make a mini Sub (Rc of course) for exploring a lake! If you could help me with the design that would be great!!! I also want to add a live feed camera inside so I can see the deep. How much would it all cost?
my problem is that how are you gonna change the motor signal i mean when you want to turn your motor clockwise to counterclockwise ? so i know that when you change the wires + to - or - to + your motor signal changes right ? how do you do that ?!
@sfalcon94 Simply have the back end of the syringe and the electronics in a dry part of the sub. Only the ballast chamber needs to be connected to the water outside. It can even be connected via a small piece of tubing.
Awesome, I've always liked r/c and really interested in r/c subs. Except I don't want to pay more than $100 to build my own (I play with a $30 store bought sub now) This setup looks fantastic and probably didn't cost much at all. I was just curious what plans you had to protect this motor from water? Are you going to put this whole setup into a tube and run the pick-up line outside?
@ToKoMiKo Yes, The motors would be dry. The design I want to use is with a stepper-type motor made directly onto the shaft. Then the motor will not stick out beyond the wall of the syringe and the sub can be made with a front and aft ballast tank by sliding one syringe in front and one in aft. Electronics and batterys would be in middle along with 3-axis accellerometer that will calculate angle so that the front and aft tanks can be individually adjusted.
I think I'll be making a controller to adjust the speed and direction. PWM should allow me to run as fast or slow as I like. I plan on adding magnets inside the backend of the plunger so I can use hall sensors to detect the endstops. Might as well make a controller with hall inputs and it can police itself :)

i have a question everything looks so good now

where did you get such a large syringe?

Once under water, how do you manage to keep your electronics dry?

Nice, Faster and simpler in operation than alot of ballast solutions seen here.

There can that is too rapid.
This way it is very much difficult to regulate the point of neutral floating in order that the submarine remains "suspended" in the water.

Excellent solution.
Really is better that my system.
I not have speed controller, and my endstops are micro-switch.
