    Heya! I have some experience with this sort of thing - the liquid level sensor corroded because of the DC voltage applied, which caused the corrosion. There are some techniques to mitigate this: you can either apply the voltage for a brief time for the measurement once every number of seconds to extend lifetime or apply alternating polarities with each measurement to reverse the electrochemical effects.
    Either way, and I say this with the utmost respect, you need to up your waterproofing game. It sorta hurts to see so many of your projects scuttled by water ingress when your waterproofing amounts to just silicone, which sorta sucks for this. I recommend you check out waterproof cable glands with PE tubing to carry conductors and some more design considerations for things like acrylic windows like labyrinth seals and compression of silicone/other seals POST-cure.
    Love your stuff, hate to see it fail due to the world's greatest chemical :)

I've actually ripped a rudder off just from vegetation that got somehow looped around it and wound up by the prop.

    For these autonomous boat projects, I wonder how a paddle wheel might fair. There would definitely be a large loss of efficiency compared to a prop, but with hopefully less trouble from seaweed you might see an overall performance boost. Seaweed could still get caught but would be more likely to fall free since the point of rotation is outside the water, and a comb could be made to grab hanging seaweed as the paddle left the water if rotation is fast enough. No clue if the overall performance would be better or worse but might be worth at least investigating. Also, would be interesting to combine such an old propulsion method with the modern aspects of being electrically/solar driven and autonomous.

    • @michiganengineer8621
      @michiganengineer8621 ปีที่แล้ว

      I'd go with a side wheel design myself in this case. Driving two (or more) side paddle wheels would be less complicated than a stern-wheel (unless you mount the electric motor outside the hull). Differential steering would make a lot of sense for a "small" autonomous rather than hull penetrations for the rudders.

  • @faragar1791

    I think you should scale the boat up to something about the size of your Boston whaler. Maybe identical canoes or kayaks with a frame to spread them about 4 or 5 feet apart you could use a small gas powered motor for an adventure like this until you could work out an electric motor and battery set up. It would be light in the water and very stable. Might need to add a keel or skag for better tracking especially with side winds and currents. It would be large enough to be avoided by most craft. You could also work on self correction like the self driving cars it make it truly autonomous.

    7:16 you could add two extra flotation tanks to the left and right of the motor directly on the transom. Basically you take some foam blocks, cover them in fiberglass (making sure they fit the shape of the transom) and you screw them in place.
    FIY you should over drill all the holes you've made and fill them with resin. Water will get inside the foam layer and you'll trash the boat if you skip this step. edit 3: to make it clear, the resin is in there to create a barrier between the foam and the screw.

    Did you add flyback diodes accross the relay? Even if the uC can handle the voltage and current needed to activate the relay, an inductive load like that will produce a large flyback voltage when you shut it off, all that stored magnetic energy needs to go somewhere and if you dont give it a path like a diode it will just keep upping the voltage until it shorts something out.

    okay so there seems to be some confusion on what "plaining" is , it is not when the stern wash separates from the transom , it is when the boat lifts onto the surface of the water or ever so slightly below it , the boat will give a very distinctive feeling when it does this , the front will go from pointing upwards to leveling off once the boat has reached enough speed to overcome the drag of the water against the hull , plaining doesnt usually happen until around 12mph

    For alternative propulsion, you can combine both wind and water :
    For wind, there is the classic sail, but there is also the amazing Kite, which could make a great project, a self launching and recovering Kite, in fact, you could even generate electricity with Kite.
    There are the :
    *Pulled by wind then retrieve through gliding.
    *Pulled by wind then retrieve through flag position.
    *Figure eight.
    *Spin on itself.
    Ways of making electricity from a Kite, all pull the craft while unwinding the cables if it has enough resistance and both the figure eight and spin method allow to still get propulsion during retrieval, but they are harder to control, while the gliding method (mostly with a self/neutral stabilized sail) is the easiest to control with simple electronic.
    As for the water propulsion, you can combine multiple types, but some are almost seaweed proof, like the FIN'X or the more typical undulating fin solution, which isn't that hard to make with as it work with a single crackshaft, as here you only need to control longitudinal thrust, unlike all those submersibles.
    One thing I thought about would be to make a Trimaran hull design, but with the side hull on hinges with a simple breaking/locking mechanism, they would use the wave movements to generate electricity, the same way a "sea snake generator" do works, except it would serve both as a "suspension" to absorb waves impacts and generator.
    A full bridge rectifier would allow any movement direction to always produce the same polarity, with a simple angle limiter and dampener, it could probably work well.
    As for the water problem, you could have two hulls, one inside the other, the pump intake and water detector (which could be homemade in 316 stainless steel or other corrosion resistant conductors as a series of close enough "pins" to detect non-salt water's conductivity) and a water pump type which can run dry, such as a peristaltic one which are not that hard to homemade, since the mechanism isn't touching the water, any small particles won't cause issues inside it, with a timer that enable it for multiple seconds after the water detector is triggered, so the movements of the boat won't make it "miss" the water.
    And waterproof the electronic with a simple hot glue gun so only the wires and possibly radiators (as it may overheat inside that) are going through it, same for the "inner" hull, which can be totally sealed off using a lead that contain the same hot glue (so you don't have to engineer a perfect fit lit with joints), bonus if you include a "hatch" with all the connectors for recharging batteries or connecting microcontrollers.

    If those relais are electromechanical they almost certainly have been overdrawing current. If there is no back emf diode it could also fry the pin.

    When thinking about boats hulls that work under low displacement you should look into a rowboat with a “shallop” or “double shallop”design. They have sweeping lines that come down to a V shaped bottom. They work amazing at low speeds and are commonly used as sailing dhingys. I’ve seen them be incredibly stable even at low speeds like 2 or 3 knots. An electric motor on one would work amazingly as they do so well at low speeds

    * Do use an internal prop with tight/angled mesh, then perhaps install some servo/wiper that periodically clears it.
    * It would be cool to install a analog (or digital) FPV cam inside a waterproof case or part of the hull to be able to visually monitor the prop in realtime. I imagine the surface light would be enough to see them doing their thing.

    Its interesting how many people try to build electric boats out of planing hulls. Paddle wheels are good options for seaweed.

Salt water will eat any of it so build it assuming that. Thick stainless will last a while.

    the drag of the water really helps with the 3d printed parts when in rotation because they are being compressed instead of stretched by the g forces from spinning

    Just a heads up, going slow and close to seal covered bouys, can be risky. A friend lost his boat when a 250kg bull that couldn't get space on the bouy, took the easy option and jumped on his boat flipping and sinking it. That also left them swimming out of a white shark feeding area in a panic

    For water level you should definitely use a ToF sensor. The Gagguino project uses one to monitor water tank height over I2C.

    On racing sailboats there is occaisionally an option for a weed-cutter keel or a rudder. Basically a knife edge that cuts through seaweed. A couple razor blades upstream of your prop will get the job done. I think I've even seen it on rc sailboats.

  • @DovahDoVolom

    Would blades at the base of the spinning prop do anything to help with the seaweed problem? I've seen it done with larger boats and wonder if it will work the same for smaller ones like this.

    If you want a better water level sensor, you can make an RC oscillator circuit out of a comparator. For the capacitor, use a circuit board with two parallel traces routed alongside one another, but leave the traces covered in solder mask rather than exposed. The longer the traces the better. You can snake them around the board to use the full surface area, too.
    You'll still want to coat the circuit board (especially the edges) in a thin layer of epoxy, as FR4 will wick up the salt water, but with that design you avoid exposing the copper directly to the saltwater.

    Have you ever considered using a pump drive instead of a prop to avoid the seaweed problem? I've been working on a 3d printed autonomous boat (inspired by your videos) and I used bilge pumps for both the drive and steering. It works great in bathtub testing, not ready to hit the big water yet though!

    Since seaweed most probably would cause higher amp draw, an automated motor reverse function for a few seconds could be enough to clear the propellers. Some propellers are also more weed protected than others. They are seen on Minn Kota trolling motors for instance.

    You could mount the solar panels above you so you can get shade and power without the chance of the panels dipping into the water.

  • @BladeScraper
    @BladeScraper ปีที่แล้ว +1

    Tip on those liquid level sensors. If you use a digital pin from the Arduino to power them only when taking a reading (say, 5 milliseconds on to take a reading, every 5 or 10 minutes), corrosion will still happen but much much slower because power isn't flowing through them all the time. Couldn't tell if you had them set up in that way but if not and if you use them again I'd recommend trying this approach. They don't pull very much power at all and they can easily be powered by the max 40mA that can be supplied by a digital Arduino Nano pin pulled high.

  • @hillonwheels8838

    Could you thread or put a groove in the prop shaft that would try and push the water down and out of the shaft tube back to the prop? It could help keep water out if that is where the water is coming in.

    To clear the seaweed, would an automated (or manually-triggered) routine to spin the props backward and forward rapidly a few times help maybe? Or maybe replacing those side prop guards that are meant to keep seaweed out with servo-actuated arms that stick out wider and can be pulled in occasionally to let any collected seaweed fall away?

  • @Grevlain

    For the seaweed problem - how about water jets? You would just have to work on a carefully designed intake system so it would not get clogged. But then the water jet exhaust would be great at pushing it through the water.

    Hi, a long time ago I sent you a message on Instagram about hubless props. Apparently they're a lot less prone to seaweed and other stuff. You only have to do a cycle backwards every once in a while. And you have to incorporate it in the hull otherwise you still have surfaces where seaweed could hang onto.
    Sorry for my bad English btw.

    Looking forward to the next video and seeing what you come up with for the propulsion system!
    For the bilge pumps, big boats use float switches. Maybe there's a commercially available product but otherwise it shouldn't bee too difficult to build your own, especially with your creativity and prototyping/construction possibilities with the 3D printers. With one of those switches, only a float needs to be in contact with the water and the electronics can be kept high up. Salt water and electronics is a nightmare.
    Good luck!

  • @elitefennec2512

    I wonder if you could install a sharp blade close to the propeller shaft that would cause the seaweed to rip itself apart when it finds its way around the shaft or even using a fire wire brush along the top of the shaft. I've always wondered if that would be something that would aid the boat in clearing such obstructions, i usually seem to get the same thing happening to my little scale boat after i've taken it out.
    I did find putting a small moulded shim shroud from the hull to the back end of the prop can aid in the prevention of clogging, though not sure what it would do to the efficiency of the boat.

  • @misery13666
    @misery13666 ปีที่แล้ว

    I think for the full size autonomous electric trip next time, a catamaran is the way to go. Allows you to take tohe boat own to its pontoons and put it on a normal trailer. Water tight pontoons give you a mix of engine/battery room, and dry secure storage, netted center basically gives you a hammock/trampoline to lay in as you cruise. You could use a tent for shade and bug proof sleeping that is easily taken down during day. exterior edges give you raised areas for solar panel connection. Honestly if i didn't live in the desert I'd want to make it myself.

    Those water sensors corrode because powering them makes them act like a battery. They last much longer if you only switch the power on for a moment every now and then.
    The other way to detect water is to run the pump and measure how much power it draws. It takes more power to pump water than air.

  • @natehill8069

    You should look into the Hobie Mirage drive. It’s essentially 2 fins that swing in a 180 degree arc in opposing directions. It’s used as a kayak pedal drive and is extremely efficient. It would be interesting to see an electric version. It would most likely solve a lot of the problems you’ve been having with sea grass.
