But I can see it will be great for analysing how the motor runs under load in various scenarios like in air, in oil, in the thruster housing in air, in the thruster housing in oil & with differing temperatures in the surrounding water. ( kitchen sink) Am away at the moment but are looking forward to testing when I return.

There wasn't enough material for a proper documentary, and arguably there isn't even a plot. But the goal of this short piece is to demonstrate how enthusiastic scientists get when offered an opportunity to dive in subs, and that we can offer such opportunities safely and professionally. For those of us lucky enough to have a sub, it's a lot more rewarding to use it for real purpose. For the scientists, it's an opportunity to finally see the subjects of their study face to face, and to go deeper than on SCUBA. I will be sending out a FB update too, so if you are on that I'd really appreciate sharing. If you are on any other sort of social network, I'd really appreciate sharing links to the website and/or video. The idea is to get the word out to the educational and research communities, as surely there are neat ideas for future expeditions within those groups. The video is accessible from either the Expeditions or Videos tab: https://www.innerspacescience.org/ Many thanks to everyone who pitched in on this initial expedition. Particularly to Cliff and Hank, who towed their boats half way across a continent. To Jon and Dan, who coordinated surface operations. To Ian, Brian, and David who were support divers. And to Shanee, who not only contributed an inflatable but jumped into the freezing water without a wetsuit to retrieve the glasses I so cleverly dropped off the dock.? Best, Alec ?? _______________________________________________ Personal_Submersibles mailing list Personal_Submersibles at psubs.org http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles -------------- next part -------------- An HTML attachment was scrubbed...

The design of the oblique cone is a series of circles, descending in diameter perpendicular to keel, and parallel to each other. The reason for me is the design aesthetic of 1) the tapered design allowing the front pilot sit lower than the rear pilot, 2) it looks like it's going a 100 mph while sitting still. 3) if you have ever sat in the first car of a roller coaster cresting the highest peak before the drop, that is the feeling you get in that seat. 4) if you remember the movie, Fantastic Voyage, the pilot sat in a large dome. That's what the rear pilot for me feels like. The exoskeleton shape was inspired by the Delta Flyer from Star Trek Voyager series, and an organic forward canard from a humpback whale. My mission with the SeaQuestor, is to teach and inspire young people about the ocean and design innovation, and its gotta look cool to do that. Remember when we went to that school in Elmarada Florida, and all those kids being so excited, well it struck a chord with me, so we shifted from a production design to a teaching tool, and of course exploration. The same thing happened in Tahoe with the kiyack group. And of course based upon the length of this email, I like to talk as well. I am sure I will find something that I could have done differently as we continue the build, but that's all part of the journey.

Even the previous day when we launched on the west side of the lake and the waves were not as large, it was still difficult transferring in/out of the? small inflatable.? I understand it is practical in terms of transportation on the road but in my opinion, on the water it becomes very impractical with seas over a foot or so.? It's weaknesses in being lightweight are illustrated pretty well on a windy day.

For most of the time it was ok with two passengers. However the large seas that Jon and I experienced on Cliffs dive at San Harbour were a bit of a challenge. For towing we had a merc 15 which for that boat was probably oversize in the weight class but not power. When I was towing the R300 back around the point, with the larger waves, you definitely knew you had 4000 lbs behind you. I would go 12' min and maybe the same size motor if I was going to be towing the SeaQuestor. You don't realize how much gear you have as a support vessel until it's all around your feet after taking a 4'+ swell. The extra length would take care of that problem. I'll be looking at all of those issues as I look for one. Hey question, Did Tahoe charge you for launch and recovery for your rib as well as the sub?

I am thinking about a 14 to 16 foot rib. I also have a real solid 14 aluminum Misty River that has a tow post and stearing station that will fit on the trailer with E3000. I could put my 10 foot rib between that and the sub.

For most of the time it was ok with two passengers. However the large seas that Jon and I experienced on Cliffs dive at San Harbour were a bit of a challenge. For towing we had a merc 15 which for that boat was probably oversize in the weight class but not power. When I was towing the R300 back around the point, with the larger waves, you definitely knew you had 4000 lbs behind you. I would go 12' min and maybe the same size motor if I was going to be towing the SeaQuestor. You don't realize how much gear you have as a support vessel until it's all around your feet after taking a 4'+ swell. The extra length would take care of that problem. I'll be looking at all of those issues as I look for one. > Hey question, Did Tahoe charge you for launch and recovery for your rib as well as the sub? > > Best Regards, > David Colombo > > 804 College Ave > Santa Rosa, CA. 95404 > (707) 536-1424 > www.SeaQuestor.com > > > >> On Tue, Sep 4, 2018 at 6:22 AM hank pronk via Personal_Submersibles wrote: >> Jon, I have to admit, Dan did the transfer of passengers with the inflatable, not me.

The speed controller is connected to the computer & I can monitor the temperature of the motor & esc as well as Watts, Amps, rpm etc. In air I was only drawing around .2 Amps for the whole range. In oil strangely enough I was drawing less amps to begin with but this evened up at around 800 rpm. Bearings must have liked the oil. After this the Amp draw went up to 1 Amp at 2,400 rpm. There are veins at one end of the motor for cooling & these agitated the oil quite a bit as the rpm advanced.

I am going to grind off some of these veins & see how it goes. The oil had a massive advantage in cooling the motor but it looks like I can only run these motors continually at about 25 Amps off 48V. On higher Amp draws up to 40 Amps the temperature was climbing at nearly 1C every second untill it hit 80C, at which stage the systems over temperature protection cut back the Amps. Great to be able to dial in loads & speed on the laptop & get accurate motor performance data back. The screen shot is of the Vesc tool that is free! I know the Vesc motor controller runs brushed motors but I am not sure what diagnostics you could use on them.

In addition I have opted for 3 hall sensors & a temperature sensor, which gives you another 6 thin wires that take up less space than a single phase wire. Hall sensors give me better low speed operation, but if they fail the motor still runs. You have your 2 battery wires connected to the Vesc speed controller (inside the hull). In my test setup there is a micro usb cable from the Vesc to the computer. The temperature sensor is invaluable as I didn't have one in my last thruster pool test & ran a thruster for 30hrs & cooked it. The Vesc also has a temperature sensor & if either hit 80C the power is limited till the temperature drops. In the attached photo you can see the cooling veins I was talking about. I will be removing 2/3 of these as they are designed for air not oil cooling. I pulled this motor apart to re-solder a phase wire which had simply fallen off! The coil wire is soldered on to the phase wire & on this one they didn't do a good job.

For a K250 I think you're good with two 55 lb motors, given the limited battery capacity. Of course more power is good, but if you went to the big motors you would need to increase the battery bank as well. You will find that with the standard K250 battery bank and two 55s, the motors are for maneuvering rather than for transits, but they will do a perfectly good job of maneuvering - transits will depend on a tow boat.

I think they are about 1500W or 2hp. Cliff Redus has documented some recent modifications & David Columbo has just acquired a number of them. My thoughts are that a more powerful motor will be able to get you out of trouble in a current, & that if you are worried about power consumption then don't run them at full throttle. If you are just diving in lakes then current is less of an issue.

The 101's are 36V, so you would need to connect them in series and they'd last next to nothing. That's why they are normally 12V boats with small thrusters.

If all goes per plan, it should be able to extend about 4ft+ above the upper pilot dome height. The camera at the top is rotational and has the ability to rotate vertically as well. The tube is located forward of the front pilot station, and when retracted, will be flush with the exoskeleton fiberglass shell. The main reason I designed it was so the forward pilot could extend it a bit, and then rotate for sideways and rear view videos. So, I decided, why not let it extend up 6 more feet. So that's the plan anyway. But cruising just below the surface and viewing the world thru the periscope cam I think will be cool.

The story is he had a submarine in his garage here in Santa Rosa, CA. When he died, it was sold to a local restaurant who may have put it in the faux lake behind the restaurant until the city had it removed. From what i can gather on its description, it may have been a k boat. I'm wondering if anyone may have any additional information as i have never heard of a k boat here.

The flat sides are on top of square forward MBT,s The tricky part is the sub is very wide on purpose. That is what gives in amazing stability. I designed the sub to be stable and to behave while submerging. The extra width is worth sacrificing sex appeal Remember I am not looking for a date lol.

In the pic you sent the other day showing the frame, it looks like you have a bracket for a round item that I thought might be your fibreglass propane tanks. So I am not sure where the square tanks fit in. Also I thought the propane tanks were to counter the negative buoyancy of the pressure hull & would be positioned around it, or did you say you were diving at an angle!

You definitely have to protect those propane tanks, as if they were hit with a stone in transit any dents could make you nervous. Maybe you could have frame protection for the bottom of the main ballast tanks to half way up as it is not as critical as the top half. Also maybe transition to the curve of the propane tanks, but that would mean a fibreglass shell. Hope you don't mind all these questions, but I thought you put the propane tanks on to counteract the negative buoyancy of the pressure hull, that's why I assumed you would be diving on an angle with their placement.

I was going to suggest having a switch to switch from charging the batteries to running the motors, as you may need to restrict the amps going in to the batteries depending on their rating. However you may recall me posting about keeping battery to controller wire length short to avoid large voltage spikes in DC systems. You would have a very long wire length from the generator to the motor controller carrying DC. A battery can act like a large capacitor to absorb voltage spikes, so maybe it does need to be incorporated in the system. It may be that you need an AC generator & a rectifier nearer the motor controller. Voltage spikes from the motors could be a problem but I guess your motor controller takes care of this. Some motor controllers have regenerative breaking that feeds power from the motor as it slows down, back to the battery. This is probably not a problem with a sub as you wouldn't get back emf like you would from a car running down hill, however I test my motors from a 48V rectifier & they advise to turn off regeneration on my motor controllers in case it wrecks the rectifier. There should be a lot of information available as off grid people combine generators, battery banks & other forms of power generation.

Just cautioning Brian to research it as there are a few things that indicate it's not as simple as just wiring a generator output straight to the batteries. You mentioned a regulator. If he pumps more amps in to the batteries than their rated charging rate then they could get too hot & off gas. Also (repeating myself) you would have a long length of wire carrying DC from the generator to the motor controller if the generator is sitting in the inflatable tender. In the article I quoted last week, an electric motor & controller builder of 30 years doesn't recommend over 1ft in length. (you can have a long length from controller to motor) They do say that the battery can act as a large capacitor so connecting the wiring straight to that may help with the associated voltage spikes, but again you would need some sort of charge regulation. Just know my 48V rectifyer & charger weren't cheap, & the rectifyer is only 40 Amps. I am not sure how many amps Brian's generator puts out.

Mount the outboard on the sub & control it from the conning tower or create a small platform to stand on & operate it. However it's going to be a pain transferring it to the inflatable. Much easier to just tow it with a support vessel with a powerful motor.

But you've got me thinking, maybe if I attached rudder planes on to the motor pods I could effect directional change , then I could have a single source outboard on the back of the sub.

If you replaced that with separate alternators, either 4 or 8, then you would need a petrol or diesel engine with a belt drive system to turn all 4 or 8 alternators simultaneously. Then you still have to deal with the long length of wire carrying dc current to the motor controllers if you want to power them directly. Like the idea of the deck chairs. Herve Jaubert built a can over an outboard & had it pressurised with air at ambient pressure so the water was kept at the bottom of the can. It worked but he said the controls from the motor to inside the sub took a bit of work.

Only trouble is petrol being lighter than water it will give you some positive buoyancy. You could just tow the sub with the inflatable & that would be the same hp but you wouldn't have to swap over the outboard. I have had to transfer an outboard from an inflatable to a moored yacht & transferring it was not much fun even in calm conditions. I am sure you would regret it. I am not sure how your yacht is set up but if you bought a long shaft outboard you could use it on your yacht & inflatable.

They have these new propane powered outboards that look pretty nice. I'm thinking that If I mount two outboards right behind my motor pods I might be able to affect turning with my motor pods. Carry an inflatable where I could mount the outboards on the back. I would need to have a small crane on the sub to easily transfer them to the inflatable. If the inflatable was mounted on the deck it might not be too hard to do. I wouldn't wand to try and do it bobbing around in the water though. The propane fuel would be nice though, no worries about water in the gas or spilling into the ocean, it could be mounted on the sub and go down with the dive. > > Brian > > > > --- personal_submersibles at psubs.org wrote: > > From: Alan via Personal_Submersibles > To: Personal Submersibles General Discussion > Subject: Re: [PSUBS-MAILIST] 48VDC generator > Date: Thu, 13 Sep 2018 10:04:24 +1200 > > Hi Hank, > Brian's proposal was to use a generator sitting in an inflatable.

If an alternator does not put too much current into your car battery then why would it put too much into your submarine battery. Yes the motor draws say 100 amps but it is drawing from at least 4 batteries but likely 8. So the draw is minimal per battery and likely less than the typical demand in your car. If you put two 24 V or 4 12 alternators directly to the batteries, it is the same as your car.

It looks like they are press forming the acrylic. Does anyone know anything about their process.? https://www.architecturaldigest.com/story/triton-unveils-66002-worlds-deepest-diving-personal-submarine To reach these new depths, Triton constructed an advanced acrylic hull for its passengers to sit inside while maneuvering below the water. Traditionally, acrylic spheres in submersibles are made by casting two separate halves together. Instead, the hull of the Triton 6600/2 is built from single slabs of acrylic that are heated to a pliable forming temperature, then molded into the frame. ?The acrylic has always been the problem in the past. There was no one who could make the material thick enough, with the quality you needed, to have a sub go to such depths as with the new 6600/2,? says principal designer John Ramsay. ?The innovative construction is the big piece, and the properties of this acrylic are absolutely fantastic?they?re substantially better than what would typically be required for an acrylic pressure vessel.? At eight inches thick, the Triton 6600/2 features the ?thickest acrylic sphere in a submersible to date,? according to Michael Haley, Triton?s U.S. director of sales and marketing.

"The greatest leap forward in the submersible world has been in the acrylic spheres where passengers sit inside. At $500,000, it's also the most expensive component of a submersible. The Triton 7500/3 has the thickest transparent acrylic pressure hull ever produced (12 inches thick), which is capable of withstanding the crushing weight of water at 7,500 feet."Traditionally, acrylic spheres in submersibles have been made by slush casting the material then bonding it. Triton together with two innovative German companies pioneered a new and much better acrylic manufacturing methodology (thermoforming), which results in material that is far stronger, clearer and superior to anything previously made. "Evonik Industries in Darmstadt manufactures the acrylic block and thermoform discs made of acrylic into hemispheres," Lahey explains, "and a second company Heinz Fritz in Herbrechtingen performs the machining, polishing and bonding necessary to create the finished product. I presume this is just a massive version of the pressing process that Emile uses for his domes.

Am looking for a small gearbox similar to the one below with the double output, but with reduction gearing, to be used for rotating the joints in a manipulator. Preferably of non corrosive materials. I fear I may have to make it! I have purchased a couple of motors from BLUE ROBOTICS. The M100 (135W) & M200 (350W) http://docs.bluerobotics.com/thrusters/motors/ These are designed to operate underwater without a housing, you just need to pot the wires. I have other plans for their use. So the idea here is to design a relatively cheap manipulator that avoids the hassle of building waterproof housings & compensation systems. My main intended function is to be able to reach to my thrusters & cut rope in an entanglement. It won't be as robust as a manipulator made using pistons but will have more range of movement & be easier to detach at depth if needed.

I want to lift as much as I can, at a reasonable speed, with the power available in those two different motors. There is a bit of compromise here as I am powering it with an off the shelf item & was hoping there was a suitable gearbox about that would get me in the ballpark. I have ideas of putting a camera on the wrist & using the manipulator as a snorkel; so it will be reasonably long. Just finished my latest motor housing, (which took a long time) so trying to avoid more hard work lol.
