Hello all,

Yesterday I made a big step in the direction of being able to sail the boat, which I hope to achieve on juli 13th when my new club has a model sailing competition. The next step will be to transfer to inputting the commands and having them end up controlling the steppers and main engines.

https://www.youtube.com/watch?v=ClzWigQk960

Image

Someone in my new club somewhat jokingly suggested that some water detection would be a good idea, so I got going on a very simple version of detecting water (simple cutting a wire in 2, glue both ends to the bottom at a small separation) and then I made these drawings indicating where the water is actually detected. This is not really a luxury on this model since the bottom will most likely be completely or almost completely covered by electronics making it very hard to actually find leak water. Now I need to remember when adding all the electronics to also leave room for a hose so I can also get the water out as well.

Image

Put the LED's in firmly and made sure they don't leak any light.

Image

Connected all the - wires, at this point thinking I would use wires rather then a PCB to connect the LED's. Added downside of this approach, and benefit for a PCB is not needing more wiring but bringing it all together in 1 central place and handling the connections there.

Image

I started working on the detection grid, the first 2 frames are wired now. I put the first panel at a possible location to how things will work out, though the PCB still needs to be added here.

Image

Indicating a leak in frame 28, with bear eyes the number is perfectly readable, it's the lack of contrast in the camera that is not showing it in the image. The LED's have already got a resistor fitted for powering straight out of the 12V battery.

Image

The PCB has now arrived, I hope I chose the right diodes, these appear to have a fairly high resistance, but then it needs to deliver a maximum of 3,3V to an input pin on an IO multiplexer.

Image

A PCB cannot get any simpler than this. This is a practical solution for powering all devices connected to an I2C multiplexer, which is why I designed this PCB.

Hi all,

Image
At the moment I've waterproofed the hull again and am now in the process of filling and sanding the new edges so the fit nicely, then have the paintwork patched up again, at least on the bottom so I don't need to turn the hull on it's side anymore. In this process I will also finish the inside of the main moonpool because there will be 1 more watertight connection so I can open and close the lower moonpool door. When this is done, I will start with making the power wiring throughout the boat, which should've been what I've started with on the test setup in the first place. Now nowing what I learned from making the setup I will now start putting everything back in the boat, power first, then communication and after that the electronics and all devices, all with proper cable management. This saves me having it to do it twice and currently I'm confident that all I have works as intended.
Image

Image
Perhaps the moonpools for the dive bells aren't as big as they should be but no-one will ever see them in a way to be able to spot this.
Image
Here is 1 nice job finishing the inside of the moonpool with only 1 photo as reference.
Image
The styrene sheet didn't fit quite as well as I hoped, apparently I hadn't taken off the material smooth and far enough. I'm going to rectify this mistake now.
Image
I didn't glue the deck in place, I'm only checking how it all fits and what needs to be done to improve the fit for when the time comes.
Image
Nice overview, I'll need to check some measurements because I recall being able to walk with 2 people side by side through the corridor where the crewmember stands, but as the lines indicate, that will not fit here.
Image
Also added some supports to the ROV hangar so it isn't hanging off of the moonpool anymore.
Image
Printed some nice supports to mount to the frames for holding the electronics.
Image
I prepared the fuses for both the 3,3V and 5V regulators.
Image
Printed a new foundation for the 8-way relay module with room for a 3,3V regulator, a 5V regulator and a MCP23017 port expander.
Image
Still need to modify the lower end of the new moonpools so the battery can sit flush on the bottom again, or make a support so the battery will no longer rest on the moonpools.

Hi Chris,

Yeah, I sure have a lot of wires and the power supply wiring isn't even finished yet and also the on/off functions mostly still need to be wired. I keep an Excel sheet as a guide to keep track of everything including the functions of all wires in a connector for ease of maintenance and installing up front. There is simply no other way going about this, I can keep track of quite a lot in my head but this way to much for me as well. I also use a second Excel sheet for planning which steps I still need to take and how far they've progressed which also doubles as note list so I can keep track of all things I need to look out for and ideas for how to make things happen.

chrisb

That's a good question. I know 1 thing for certain, I won't stop until I finished this project. The planning I mentioned above in this post says it could be done in like 8 years at an average of 1 hour a week, considering all things start falling in place relatively easily. This includes time for programming and designing of parts so it's quite complete. Below I attached the current status, mind you, this is not considering the construction of the hull since I only started using this planning like 2 years ago.

To add to the current status, I have made the hull watertight again and right now I'm focusing on getting the bottom finished and fully painted. After that I'm going to install all the power wiring in the boat, followed by the communication wiring and electronics and then all the different functions. The reason behind this decision is that I need some positivity in my life and I started without a plan with the test setup, making a mess of the wiring. So, rather then taking all from the test setup and building it up again the right way I use the moment to make a step towards sailing while fixing the problem in 1 go, now with a plan.

Hi all,

Image
Oh dear, oh dear, what did I just do?? Now being 16,5 years into this project having never ever even considered making the retractable schottel fully working (even though making the 2 in future project Seven Atlantic working was never in doubt) I decided I had to make it working, even if only to try it out before the Seven Atlantic. Considering I really want to try to have Well Enhancer sail this sailing season this was about as late as I could still afort making such a design and make it happen as well. Therefore I picked up my multitool and started making the needed cuts in the hull. Next to the hull I hold the final pocket in which the retractable schottel will be kept with all the components needed to attach 3 guiding shafts and 1 M4 thread which will move the entire assembly up and down. Before printing this final version I printed a version without any holes just to see if I can make it watertight, which proved a resounding succes.
Image
Designing the schottel is coming along nicely, the schottel design itself is almost finished though I still need to come up with a proper solution for making the connection between the mounting plate that makes the schottel up and down as well as holding the needed motors and there sensors because the schottel needs to turn, have it's removable gear atop (5mm high) and I need to keep the height as low as possible. The entire schottel need to be removable so I can even replace it if need be.
Image
This gives some indication for how the assembly will come together, though this schottel is still printed in PLA rather then resin just to check the design for proper fitting and whether it will work the way I want it to. The final version will be shorter then what is shown here to optimize the available space and the vertical gear didn't fit as well as it needs to so driving the propshaft wasn't going to happen in this version.
Image
This is the definitive design for the schottel itself, the vertical gear now fits properly and there is enough room for maintenance. The final version will be printed in resin so I only need to paint it and assemble the entire assembly to make it work as intended. Because of the choice for resin I will add a resin ring to act as a seal in the pocket housing the schottel because this ring can be made watertight with the pocket with as much material as can be reasonable for the application without needing to worry about fixing things that should be able to turn and move.
Image
Now back to now, I only need to fill up the gaps with greenstuff and I most likely will poor some epoxy resin in there after that to make sure all is really watertight.
Image
I started sawing the hole a little small hoping to make the hole as precise as possible with regard to keeping it all watertight. In the end precise turned out a little difficult under these circumstances. The piece of bottom I cut out is laying atop the hull.
Image
I wasn't done just yet making holes in my hull, there were 2 more to go for the dive bells. The moonpools that will be fitted in these holes have yet been 3D designed and printed with some supports to fit the moonpool to the frame (the battery will fit directly between the 2 moonpools) and also some support for adding the winch later on.

At the moment Well Enhancer is in undergoing maintenance at Damen Shiprepair in Amsterdam. where Seven Atlantic (a future project for me, I walked on her while she was only a double bottom) was laying 2 piers further after having docked for a new paint job. It made quite a picture for me:

Hi all,

Image
In the last couple of weeks I continued the work on programming and working towards a finished test setup. This feels like a process of 1 step ahead, 3 steps back. Considering that it used to feel like 1 step ahead and then 5 back I am making progress, also when considering that 1 set back doesn't take me a year to solve any more. By this time I have arrived at the point where I can actually start making all things come together quite quickly when the last pieces of the puzzle start falling in place. For that matter it would help not to create a short circuit through the address pin on a port expander, destroying a Pi, a motorhat and 3-4 PWM modules in the process. The port expander already was to be replaced by a different chip so that loss is not much a problem, the Pi and motorhat are big problems, though they will end up in the transmitter, where the motorhat will control the helm indicators.
Image
After trying MOSFETS to control the winch motors resulting in blowing the MOSFETS up, I ordered some 40 continuous servo PCB's leaving me a couple for the life boats. When testing these on the PWM modules I got no stop and also no reverse, but using the servo tester these work fine, also for the lifeboats, which I tested seperately.
Image
Got myself a couple of new pumps which will be the cooling water pumps and for flushing the anchors. The new pumps are so much smaller then what I originally got myself which is a great benefit. These pumps don't need to pump large amounts of water so these seem fine.
Image
Sometimes a change of scenery helps to keep going. Therefore I decided to glue all the outer walls of the superstructure together.
Image
The whole ship looks a lot better too, so I'm very happy about this progress. The newly painted crew (still work in progress though) also adds to the improvements.

Hi all,

The last 2 months I have been quite busy arranging and still finishing a dormer which was placed on my house now 2 weeks ago. In the meantime I have been working on a model of the work I do nowadays which will be used to sell the products I work on at expo's. Encouraged by these results I decided to pick up my own project as well.
Image
I mounted the entire plate on drawer slides to make everything more accessible without hitting the roof with my head. Since I needed to clear everything off the plate for mounting the slides I also decided to clear things up a a bit and start working on the power supply and it's wiring. Even though this is not a small plate, it's still quite small to fit all the electronics of Well Enhancer.
Image
Using some Tie-wraps to tie the servo's and electronics down this looks like a decent enough testing setup, especially with the servo horns now put atop the servo's. Next up is preparing the power supply wiring and connecting all the wiring. I will also upgrade this to a fully equipped with a PC power supply powered labsupply and storage for spare wiring and spare electronics parts as well as some tools needed for working with the wiring and electronics, alongside upgrading my spraybooth with some proper ventilation and lighting.

Hello all,

In the past couple of weeks I have been focusing on getting the Well Enhancer sailing before the end of this season but after running into a multitude of problems, mostly regarding the wiring, I decided to go back to the drawing board.
Image
I chose the literal drawing board as well, since I painted school board paint on the wooden shelf so I can easily make notes and remove them just as easily. I will paint a couple of lines to make things more organised. In the background the new main I2C cable is visible, this has 5 connectors to which a second cable is connected with 1 point where I will solder all the needed wires and there is a spare connector for just in case I find some more needed devices connected there. I will also use wire numbers to make things clearly recognisable.
Image
This image gives some idea of what I'm going to. At this moment I still need to remove a lot of stuff out of the boat (including the main computer, still in progress of building up the new version) and still have some stuff to buy as well. I now really want to see everything working, including all servo's and motors though for LED's I'll use some test setups because of the practical reason of having the LED's pretty much all mounted on the other side of walls or decks.

Hi all,

Image
This week I received the improved PCB's (10 in total) and quickly found out why putting text next to connectors showing the purpose of each pin is so important. Now it was easily visible that the + and - wires are at least multiple times connected the wrong way around. I already started fixing a few connectors but I still have a long way to go to check all the connectors and fix them all.
Image
I put all the new PCB's where the will end up, though I still need to solder the resistors for selecting the I2C adress. Since I keep using the 2 modified somewhat older PCB's as well I'll have 2 spare PCB's now.
Image
The new version PCB along the 2 now obselete PCB's which will be replaced by relais modules along with the new version PCB. This solution is both cheaper and more practical in terms of room and flexibilty of placement.

Hello all,

Image
Today I managed to fix the issues I found earlier this week by cutting through a solder lane on the PCB and attaching 2 wires because I had 1 adress pin connected to GND and the other to the + but both needed to be connected to GND and turned out to need to actually be connected to GND (that was blocked by switches thinking I needed to short it in order to get the default adress. Also, the Reset pin turned out to need 3,3V in order for the chip to boot.
Image
This test set-up I used to get to eleminate the problems with my self-designed PCB, though I cheated a bit by using a similar but slightly different chip (functionality is the same, pin layout is slightly diferent though the functions of the several pins are same, just in a different place) because I ran out of the correct chip. I tried removing 1 from a faulty PCB but I couldn't get it loose, that made me decide to not solder the chip directly in place anymore but rather have an IC holder in place and put the chip in it.

All in all I got a couple of great break throughs! The party isn't yet complete though, since the Pi in the transmitter only accepts connection for a couple of minutes before freezing totally and the Pi in the boat refuses to pick up the the I2C devices for some still unknown reason. I did get to test the NRF24 transceiver and that seems to work though it is difficult to know that for sure without another transceiver to communicate with.

Hello all,

It's been a while, haven't got around working on the model a lot lately though I did get some important break throughs in the background. I decided that having the deck surrounding the dive area and housing some davits for lifeboats fixed to the hull creates all kinds of problems when it comes to making the davits work so I will make the deck with a bit of the walls below it removable so I can use the large open space in the removable section of the dive area for electronics and servo's without inferfering with the main computer and the battery. I have now also made some software reservations for the dive bell so should I decide to make it working as well I only need to add some working works.

Yesterday I uploaded my first video to YouTube where I want to keep track of the build process like I do here:
https://www.youtube.com/watch?v=sVQar8oVR84&t=85s

Image
Project Flying Helicopter is GO! This helicopter is to land on the helicopter deck, though I do intent to try and make it look like a Sea King or Super Puma used by some offshore company, preferably with a bit of cockpit interior if the battery there allows it.

Image
The size fits well for the helicopter deck, though that is yet to be build. My focus is currently on other, more important parts of the ship.

Image
The main computer proved to big to get access to electronics once the main deck is fixed in place so I designed and printed a smaller version which I now started to rebuild to.

Image
By now the fuse box is moved to the new main computer, I still need to design and print the electronics rack to fit in here.

Image
Still a lot to be done! I got a new PCB which acts as a computer like power supply for the Pi and I also replaced my first self made PCB's by a new version to get rid of the short circuits in the old design.

Image
Lastly I updated the list of functions and mostly the corresponding commands and decided to add 2 more PWM modules, 1 in the drilling tower and 1 in the dive area so I can keep the number of wires going through connectors as low as possible.

Greeting, Josse

Hi all,

Image
Currently I'm running into communication problems in the programming so I decided to let it rest hoping to find a solution later and instead pick up work on the superstructure by glueing the 2 sides and the front together.
Image
The remaining gap in the top layer will be filled up with a resin printed and fully detailed part.

Image
This morning I found on Vesselfinder that Well Enhancer is in The Netherlands today so I grapped my camera and went out there and took quite a lot of close up photo's for as well as I could get to. The close-ups (My Nikon 200-500mm lens was worth every penny today) revealed answers to some questions while also revealing that I missed i few functions that I should make working like 2 fire monitors atop the Dive-area, a personel lift at the back of the drilling tower and a hoisting derrick also to the rear of the drilling tower.

Hi all,

Image
The main propulsion is finished for testing! I switched the engines back from the Johnsons to the Speed 500E's I used on the original Well Enhancer, mostly because the drive shafts of the Johnsons is just too big for the timing pulleys, the Speed 500E's don't have this problem. I drilled a hole and tapped M2,5 thread in the hole to secure it. After fixing all these minor issues and finishing the remaining items to get it all working I also tidied up the wiring for as far as it is now finalised, I stopped where I know the wiring still needs to be sorted out. Off screen I also made a cabletree for the I2C wiring to connect the PWM module (and thus the Pi) to the 16x2 LCD screen and the rest of the ship through the self designed PCB housing the midships multiplexer.
Image

Image
I am thinking about designing a proper mount for the 9DOF positionsensor in order to ensure any anomilies in the readout cannot be from the sensor moving all about the place.

Hi all,

Image
My goal for this year is to get Well Enhancer sailing, so I need to finish installing the thrusters. I've been at it for about a week now with some proper steps made towards actually working thrusters. In this photo I collected all the needed parts, including the PCB's that will end up below the stepper motor in order to register the thruster angle.
Image
I soldered the ribboncable to the PCB off screen but I do need to provide better means off fixing the mounting plate for the PCB then the balsa wood. I designed the plate such that I can align it to the stepper motor.
Image
Coming really close to having the thrusters working! I am going to change the engines back to the old engines that also powered the first version due to poor fitting of the timing pulleys. I will also sort out the wiring a lot more once I tested the thrusters since I think some wires are now not attached anymore.

Hi all,

Image
I printed almost a kilo filament into new parts in a week, the printer kept working throughout Christmas as well. One of the results is this engineer mounting housing 2 fire pumps (the second one will be mounted to the rear) and also some electronics.
Image
Made quite a big decision here. Rather then even trying to skeeze a camera, some servo’s and motors into a 4x4x3cm small ROV and trying to make a cable anywhere near scale size I decided to make a hangar with an actual working ROV (which is much bigger) and for which the size of the wire is not relevant as it’s out of sight anyways. The hangar will have a door entering the moonpool so I don’t need to make all to much modifications.
Image
I still need to modify the feet which are to place the hangar at the intended height and I need to give some thought to waterproofing the connection since the lower part of the hangar will be below the waterline. I also printed a nice support for my self-designed PCB and a motorhat that will control the rotation of the crane atop the drilling tower and the crane to the rear of the dive area.
Image
Power is back online! I tested a relay setup to switch the extra functions (all kinds of lighting, secondary cranes, fire monitors etc) but the switch that controlled the relay for some reason lowered the 12V I put into it to 2,5V which proved not enough to switch the relay. Therefore I got rid of the relay and it’s switches and put in simpler switches that can handle 3A (which I recon is more then enough since where talking to groups here, so 6A in total) so I can save power when I’m not going to use those functions.
Image
I still need to glue the LED’s in place, for which I intent to use hot glue.
Image
Since the servomodule is quite hard to reach with all the wiring going on in front of it I inserted all the needed servo cables which I also labelled to not get confused later on. I also bundles the cables per part (all cables for the same crane combined for example) and routed the cables towards the location of the to be connected component.
Image
The inside of the superstructure is fully printed now, I only need to glue the parts together and mount all the cabins with their lighting and the electronics. In the rear I included holes for mounting 3 fire main lines (2 fire monitors and 1 for fire extinguishing on the helideck) and a hole for the VGA connector which will pass the power- and signal cables to the superstructure.
Image
The topplate has all it’s components fitted, now I need to connect all the wiring. I tested the multimeter briefly but I don’t trust it’s readings. It indicated 0,3V and 49,2A (it can handle up to 50A), so I probably made a mistake in the connections. I attached the Amp meter on the – side off the load, perhaps that should be the + side. I also don’t understand why the Volt meter still indicates 0,3V when the Volt meter wires are disconnected.
All in all I still have some things to figure out and quite some wiring to fix in an orderly manner but at least the + side of the groups are now finished so the – side of things is still on the to-do list.

Hi all,

Considering that power in the boat is crucial programming and testing I decided to unravel the wiring and start working towards finalising the main power supply and computer in the center of the ship. In doing this I found the reason I thought my Step down converter for the Pi was broken, I didn't connect it to the output side of the switch but rather to the LED connector which only gets 3,3V.
Image
A small impression of the mess I started with, including the surrounding components to make it a good looking box.
Image
I started with sorting out the wiring to get the best possible sight at which wire is which.
Image
After quite a bit of fiddling I managed to clean up most of the wiring though lots of it is not fully finished yet, mostly because the still to make wiring for the screen, battery status, multimeter and the circuitry for powering and shutting down the Pi.
Image
This is the new version of the topplate though I'll soon print a new one slightly modified version since some parts don't fit all too well.

Hi all,

Image
At the moment the walls for the superstructure are being CNC-ed so I decided to pick up the pace on making the interior construction so I can build up the superstructure when the walls come in. Due to available height the front PCB will protrude a little below the superstructure, but this is not a problem.
Image
I purposely make most of the cabins on a smaller scale then the rest of the boat to creat the illusion that the cabins are full size even though there not because of the electronics in the superstructure. I wanted to print the interior in 2 parts, but that requires quite a lot of support to print properly. Splitting the interior in 4 parts in total fully illimenates the need for support by putting the parts on their sides.
Image
After some more design changes the tensioners are now finished apart from the sensor that will register the RPM of the engines. The mounting for these sensors turned out not to fit quite well yet, though it probably will work fine, so I'll redesign these mountings to make it fit better.
Image
In my previous post the new wheelhouse print was already visible but I forgot to mention it, so let's correct that now.
Image
Here the detail in the ceiling is quite clearly visible, this will be in the entire wheelhouse.
Image
Since this part failed it is a good test subject for trying paint and glue.
Image
This is the newer and better version now painted with the black primer, now I need to get myself some white primer to make the end result as white as possible.

Hi all,

Image
After some further design modications I printed the parts for the belt tensioner and rev counter out of resin. Some parts are yet to be printed in the latest design iteration before I can start assembling the hole thing. Speaking about printing with resin, I decided that I will have the arm of the main crane 3D printed out of extra strong resin at a shop in Hong Kong because they can print such objects up to 78cm long, much more then I need but can therefore print it in 1 piece for extra strength. I will print PLA inserts for mounting the winches and there motors becsuse of the threaded inserts that work well in PLA but not in resin.
Image
After that I continued work on the brains and heart of the boat, starting with making a new brain. This ended up working fine with 1 less plate then originally anticipated saving a bit of space for the wiring in the proces.

I also made a new fuse box. In this fuse box the last 3 fuses are fused through the 3rd fuse, 2 of the last 3 are switched by relais (hence the holes in the topplate, the switches will fit through these holes) so I can sail the boat without loosing power on additional functions that are not being used.
Image
The wiring will need quite a bit of attention as it is a mess now. I do need some new switches before I can really clean it all up. The topplate for the fuse box also serves as a support for the main computer topplate.
Image
As can be seen here the end result will look quite neat though I'll have plenty to do to get there. The fuse box still needs to be fixed in place, the main computer has now been fixed though the topplate will need more work to fix in place.

Slowly things are starting to take shape but I still have a long way to go.

Hi all,

The first results for the wheelhouse are in!
Image
Though not really what I hoped for. Since the supports that connected to the window frames are much thicker then the window frames it proved impossible not to break the window frames (no :censored_2: Sherlock) so I'll manually place the supports for the next attempt so as to not have any supports on the window frames. I also found that the floor needs to be much thicker to stay straight which has now been corrected in de model, tomorrow I'll try again with the modified version. I discovered this problem after having started the print containing the front half of the wheelhouse and the crane foundation so I stopped this print, leaving me with some small pieces on both ends. The detailing that I put into these pieces turned out to be really good so I'm really happy with that.
Image
It's quite hard to tell but at the captains feet the tracks for the helmsmans chair can be seen. This way the helmsman can sit behind every part of the main instrumentpanel without the risk of his chair flying around the wheelhouse in a breeze. Unfortunately the 2 chairs here can only be fixed in place since this is still behind the superstructure and thus I can not use tracks like I do with the forward chairs. These tracks are 0,2mm thick at it's thickest so they're really tiny. I also made a slot for putting the 0,1mm thick wire for the instrument panel lighting which actually passes underneath the track for the chair at it's very latest. For the lighting the + wire will pass through either on starboard or port, the - on the wire, thus making good use of the fact that both rear quarters are pretty much mirror image from 1 another, except for the track for the charis which runs further to portside as the instrument panel is slightly offset to portside.
Image
If you look close enough you can see the joints in the ceiling plates. I really love the level of detail these resin printers can achieve.
Image
In the print for the front of the wheelhouse I also included to outer shell of the crane foundation on deck, though here the infill was not yet implemented to give it proper strength for just in case I decide to put some force on it. By now the 3rd attempt for the foundation has been stopped because there was no more resin in the vat... The hole in the foundation is purposely wide since the design of the crane that will pass through has changed since the print visible in blue here. I decided it is a good idea to have the weight of the crane being kept in check by the deck and therefore I widened the crane from deck level onwards. The new version will not be printed before I at least finish the design of the lower crane with the crane house and driving mechanics and Pi Zero so as to not waste more material then needed.

Tomorrow I intent to start the new attempt with some design modifications and corrections such as the overhang behind the rear bulkhead of the superstructure below the wheelhouse and means for wiring for the lighting of the instrument panels and the floodlights that will be mounted at the rear of the wheelhouse. The overhang will certainly have something to do with the wiring for the propulsion as there is a helm station placed on the overhang and since the wiring requires to be doubled up in ways that a fire in 1 room cannot take out both sets of wiring this well finished overhang should have been expected. Further more I'm getting really close to the point that I'm going to have the more shaped walls and walls with windows in the superstructure milled, at the end of this week I hope to know more about this but the first couple of files are ready.

Greetings Josse
