Boat build part 1 - Overview

This is the first video in a series on how to build a bait boat. The boat I will build is very small, and the sparse room to place components is a challenge. One way to solve the challenge is to select components that are small, and components with low weight.
The boat will be powered by two 3s2p batteries, it will have an autopilot, an echosounder, one bait tray and lights. And can be equipped with a top mounted (low profile) bait thrower. Target weight is below 4.5 kilo including batterier and mounted bait thrower.
PART 1: This first video focuses on some planning and includes a description of main components to be used. I will list parts needed in each of the videos to come, no parts are needed in the first as it focuses on explaining some basic principles.
Please note that I will make the videos as the boat build progresses. It will take some time, and videos will thus become public over a period in time.
Videos planned to follow up after this introduction:
Partt 1: [this video]
Part 2: Preparing a pixhawk before we put it into the boat
Part 3: Walkthrough of the additional components bought and printed
Part 4: Building the upper hull (from parts to complete)
Part 5: Installing lower hull parts
Part 6: Adding the lower hull power and signalling system
Part 7: Finalizing boat configuration
Part 8: Combining upper and lower hulls and gluing
Part 9: Settings in Carp Pilot Pro to fully support all boat features
PARTS NEEDED:
Please see table around 1 minute in for the major electronics. In addition to this table I used:
DHconcept ALPHAmini hull kit, including:
- Upper and lower hull
- Battery cover lids, including inserts to glue in and rubber sealing for edges
- Two red super bright back lights
- Two acryllic inserts for front lights (here 5mm LEDs fit in)
- 10mm plastic or carbon carrying handle
- Metal plate for bait tray trap door with hinges
- Metal weed guards
- Bolt and nuts for the bait tray door and weed guards
- High quality propeller shanks with ball bearings, pre greased
- Two propellers (for left and right)
- High quality 5dbi Antenna
3D printed parts:
- Box with lid for the Raymarine Dragonfly pro 3
- Battery holders
- Motor holders
- Motor holder for the bait thrower, and a top basket
Additional electronics:
- A wifi booster from Ali Express
- A waterproof servo
- An external USB connector for the pixhawk, incl a I2C multi connector
- A pixhawk Wifi UDP serial adapter (for secondary telemetry, can be used for primary)
Diverse parts:
- Piano thread and plastic tube for the bait tray door holder
- Deans power plugs
- Power cables (14, 18 and 22 AWG)
- Soft velcro to fix top of holder for the bait thrower (soft but high quality glue)
- 3M Dual Lock velcro for fixing diverse components (awesome stuff)
- Black Tec7 glue
Note that I ended up using the pixhawk4 mini. Reason was that I had the pixhawk4 mini available, I just put it to good use. But be aware that this autopilot uses JST-GH connectors and not DF13 (or Molex Picoblade) like the pixhawk (2.4.8) from Radiolink. I had to swap some connectors.
Note that I ended up using the mateksys M10 L4 3100 GPS. This GPS is not serial bit instead CAN. The supplied connector was a good fit fot the pixhawk4 mini. But also note: I had an older Radiolink SE100 (GPS) laying around with uBlox M8n chip. But Radiolink now builds in M10 chip as well. So a new SE100 is a great match for the regular Pixhawk.
There are more than 50 different Ardupilot compatible autopilot hardware options to choose from. But, if you are not in for some challenges I suggest you pick models broadly used, like the Pixhawk 2.4.8. Reason is that so many has built drones/cars/boats before, all questions you may encounter are likely already answered and available on the internet. The more odd solution you build, the more you need to figure out on your own!

    Hi this video series is invaluable. I have one question, I plan to install my modified deeper into my boat, but I understand it will need a wifi booster similar to the one you use for the ray marine. Can you tell me which one you used or which would be suitable for the deeper.

    The boat used as illustration (the same hull) is built with a Deeper, a booster and the same Skydroid T10. This works flawlessly. However, the backup telemetry using a wifi ESP adapter is kind of more difficult. Reason is that the Deeper's SSID is quite long (more than 16 characters, which is the macig number for many wifi telemetry adapters). I know that someone is working to fix that. But if you use the Skydroid radio then that is nothing to worry about. And the DHconcepts hull of the "ALPHAmini" is actually even designed for fitting in a Deeper (recess in the bottom hull on both sides).

    The autopilot uses it's separate telemetry data stream. Two ways to implement that is shown in video 2 and 3: using a Skydroid T10 rc Radio with built in support for mavlink, and a wifi UDP adapter that uses the wifi of the echosounder as carrier for the telemetry data

    Hi , love the video very informative and well presented 👍 could you please tell if me though is the telemetry and Raymarine both 2.4ghz? Do they not interfere with each other ? Thank you

    In this case the remote transmitter (that carries the telemetry) and the Raymarine wifi both 2.4 GHz. And they will then interfere. In addition, the water will limit the possible distance you can hope to achieve (the distances possible for a drone up in the air cannot be compared to a boat with its antenna heights measured only in a few centimeters above water level). Some transmitters are nototious in this regard. Like the trusty old Flysky I6X (although this has no telemetry support, for comparison this is transmitter is known to significantly interfere and limit the achievable distance for the Raymarine). Now, it is possible to play around with the channel used by the Raymarine wifi before altering it (the screen head unit must be used) as not all channels will be impacted equally). Not all transmitters are equal, so such testing may pay off before gluing the Raymarine in. Then, for reference, I did some range testing with this boat. And for safety reasons I activated the failsafe for GCS, and made sure the failsafe action was RTL (if the Carp Pilot Pro lost communication with the autopilot, the boats returns back home - I did not want to swim out to rescue it). I put out a marker 600 meters away. Then touched it to trigger the boat to drive to it an stop. And then watched what happened with Carp Pilot Pro and Raymarine's wifish app in split screen. Making several tests: I found that, using Skydroid radio for telemetry, the Raymarine app lost the echo sounder at approx 430 meters. For this testing I then drowe back home until the Wifish app once again worked. After being satisfied with this test I tested my secondary telemetry, the wifi UDP adapter that sends its data through the Raymarine wifi. Powered off my SKydroid, and connected using UDP. And retested. This time I typically got until 390 meters (397 being the best result), and then the GCS failsafe kicked in and returned my boat before the wifish app would freeze up. To summarize: For me, distances of around 400 meters is fully satisfying. I never fish further away. I never really tested the max telemetry distance with Skydroid. But what I hear from others is that at least 600 m is achievable in combo with the Raymarine. Now, would the Raymarine distance be better if I have also removed the Skydroing receiver in the boat? Probably. At least such effects I have personally witnessed with an older boat I have with the said Flysky. And could you get a similar effect if you use transmitter with say 868MHz instead of 2.4 GHz? Most likely.

    @@TheCarpPilot Hi , I have the Raymarine installed as you have in the hull combined with the Skydroid controller and Carp pilot pro app/Raymarine Wi-Fish installed . I have a Wi-Fi booster in the boat same as yours but it is NOT connected via a sma cable to the circuit board. I am losing readings at about 80metres from the Raymarine , does this mean I definitely have to connect the Wi-Fi via a cable to the Raymarine unit ? I know how to do it by moving the resistor on the Wi-Fi board and soldering a mini sma connector in but is it totally necessary as I only need 180 metres ? The Raymarine is also running very slow on the scroll screen , Many thanks in advance

    @@Blupa. That Booster takes an input signal and enhances it. The only way it can do that is by sitting between the "router" (in our case that is the Raymarine) and the antenna. It has two antenna connectors. One for the router (your Raymarine) and one for the antenna. And it only works with those physical connections. To use this booster there is no way you cannot first modify that Raymarine. Not explained in the video... This is Kot the ONLY way to increase the raymarine distance. You can also implement a router inside the boat. In bridge (not Extender) mode. One router that works is the Vonets VAP11S. Please do not als me how to. Because I never did. But there are Videos out there showing how to. I believe with a Deeper. But the principle is the same. And... You can have another router (also Vonets) on shore. And link everything up with two routers. And likely see 500 meters as a result. Still want to use that booster then do that soldering. Don't know how to, find someone that can help. Soldering too difficult (yes, you can damage that Raymarine for sure) the try the router way. Best of luck.

    Not a bad idea. But the motors selected are anyway tiny. And it is not just space causing challenges. Weight is equally important. The chosen motors weigh in at 57 grams (although the weight of the shank also comes in addition). All parts are bought in, so I will proceed as planned here :-)

    No PDB. The ESC get the raw power from the batteries (you need to chose an ESC that is compatible with the battery voltage). And for the servo side, the power is provided by a BEC from one of the ESC. I think the description in the video and in the drawing is pretty accurate.

    Do you need a Skydroid t10 radio to build a boat. Or can I use a regular Flysky or radiolink remote

  • @TheCarpPilot

    @TheCarpPilot

    Жыл бұрын

    You can use both alternatives. But then also add a solution for the telemetry connection (like the adapter I use in my videos as a secondary telemetry option, I believe it is video #3). If not the Carp Pilot Pro cannot talk to the pixhawk inside your boat. I used Skydroid as it can handle the telemetry as well over the remote control link. But it costs money, far more than a simple wifi adapter for around €10...

    Not an easy question to answer. But the KZread boat is small (44 cm, 4.5 kg with batteries and thrower). I just mounted motors in a bigger boat (60 cm and more heavy) and put in Propdrive V2 3536 910 KV into it. The KV value is a bit high for boats. Better to find one with like 500 KV, better for boats. The thrower motor is insane. I had to tune it down to 1650 max PWM output and do it momentary for only 1 second. It ran so fast that the basket widened on the top and I was afraid it may cut my antenna in half.
