Sounds a really fun few days. Looking forward to the video footage. Hugh From: Personal_Submersibles [mailto:personal_submersibles-bounces at psubs.org] On Behalf Of Alec Smyth via Personal_Submersibles Sent: Sunday, 1 July 2018 6:35 AM To: personal_submersibles at psubs.org Subject: [PSUBS-MAILIST] Tahoe summary Hi friends, A bunch of PSUBers have just wrapped up a week diving R300 and Nekton Gamma in Lake Tahoe, so I thought I'd summarize how it went. This was the first expedition planned with the framework of https://www.innerspacescience.org to align the use of personal subs with science objectives. That allowed us to partner with three organizations - UC Davis's Tahoe Environmental Research Center, the California Tahoe Conservancy, and the Tahoe Regional Planning Agency. They facilitated everything from our boat inspections to finding a base of operations on land, but above all provided institutional-grade surface support vessels as well as scientists. One of the first objectives was to depth test R300, and she passed with flying colors (no surprise!) Cliff had a cool way of doing the test. Since everything on R300 is controlled by a PLC, he programmed an entire automated dive cycle beginning with a 45 minute delay. He attached ballast to replace the pilot, clicked a button to start the clock, and closed the hatch. The timer gave us time to tow the boat out to depth, then automatically flooded ballast.. Attached to a line, R300 descended to around 400 feet, stayed there half an hour, fired vertical thrusters to rise, and a few feet from the surface blew ballast. Another objective was to shoot some sub-to-sub video. That day the visibility wasn't optimal, but we did get it. It was the first time I'd done a multi-sub dive and it was as much fun as you'd expect. Video to follow... The scientists had a bunch of objectives. In general we did not have the bottom time to carry out the methodical counts they were attempting, but we were able to get their eyeballs on the spots they were wanting to make the counts at, and get video. Some hypothesis were met, but new questions arose too. One of the spots they wanted to study was the top of an UW mount. Hank was able to find it, climb up, and circle the top. That was an accomplishment, because the top was only about 20m across and we were unable to locate the mount with depth sounders from the surface even when provided GPS coordinates. These spots were in 200? plus, so had not been visited on SCUBA. We were able to offer Gamma rides to a few VIPs but more importantly to many young students. You should have seen the reactions. Another time, Cliff beached R300 on a popular sandy beach and found himself giving an impromptu lecture to a circle of young people. The most exciting incident came on the last day when Cliff gave Jon and Dave some training followed by solo dives. On Dave?s dive one of the side thrusters sucked in a rope and he found himself tethered to the bottom in 77 feet. Minutes later the surface support boat?s outboard accidentally cut off the comms transducer. However, Dave followed R300?s emergency plan to the letter and blew MBTs, which ripped him free. Unfortunately we don?t have video of that incident, but it would have reflected well on all involved. The sub had a pinger to locate it, had a plan, and the plan was followed. Now we need suggestions for the next expedition! Best, Alec -------------- next part -------------- An HTML attachment was scrubbed...

The place I'm planning on ordering my external T-rings has a bunch of off-the-shelf flanges (angle rings) which could work. http://anglerings.com/Store/CategoryID/4/Level/1/List/1 For example, a 2 x 2 x 3/16, Leg-Out orientation with 16 holes in 304SS is around $150, so for $300 I could add a removable end cap. This would length the hull ~4 inches, the added weight would be reasonable close to the added displacement. 304 vs 316L. I would love to do it in 316L, but since it's only going in the water when it's being used, I don't think it's big factor. External vs internal bolts. I like going with the external bolts because this will make it easier to remove. As in I won't need to crawl around the back removing 16 nuts and bolts. This is all to make the sub easier to work on, I'm not a small person. Once I get this K250 into an operational state, I've got lots of projects I'd like to do with it, such as adding INS, sonar, manipulator, etc. etc.. Possibly going the route Alec did and make it a two person. Being able to easily remove the rear end cap will make it more likely that the other projects will happen. I'd appreciate any input on this. Thanks! Ian.

I found my linear actuator motors ran really rough in oil. I think it has a lot to do with the viscosity of the oil compared with the size of the motor. Ie. you might compensate a large motor with a certain viscosity of oil but you would have to reduce the viscosity of the oil in proportion to the size of the motor for the brushes not to lift! Can't wait for all the reports & videos once you get over your drive! Just welding up my motor test jig at the moment, your set up has been an inspiration.

If the tear down was as I remember, the DC motor was high speed with a significant set of reduction gears. On the motor was a fan with lots of small blades to cool the motor. My working hypothesis is that this fan was designed for air not light oil. As such, even with the low viscosity oil I was using, the drag caused by this fan operating in oil would be dramatically higher than for air. I think this caused the motor to consistently spin slower than with oil, this the reduced stroke speed by extending or extracting. I never tried this but if this was indeed the cause of reduced speed and not oil lifting the brushes off, then an easy fix would be to remove the fan or fan blades. I think the cooling would be adequate given the low duty cycle particularly while submerged. With the fan removed you would have to limit use out of surface to keep from overheating the motor. OAS, I enjoyed meeting you and your wife and learned some things that I will implement on my boat. I particularly like the your trailer setup for launch and retrieval. My new goal is to launch and retrieve by boat like Hank! This will entail two trailer mods. The first is I am going to weld a 4x4 by 10 extension just aft of my hitch. Maxi has a boat we use for a tender so I don't need the dingy and as such don't need a wide platform. The second modification is that I am going to install two Lenco trim liner actuators on my "Y" yoke at the stern end of my trailer and run these of the trailer emergency brake battery. This will enable me to lock in the stern of the boat without having to fiddle around in the water with straps. After the boat has been cradled and pulled out of the water and away from ramp, I can then attach straps. These changes should dramatically reduce my launch and retrieval time. I may end up using a larger trailer 12V battery than what comes with the electric brakes. I am also going to permanently attach a kit box on the extension that I can stow straps, chocks, tire tools, small floor jack plus miscellaneous spare parts. Given that my new trailer brakes failed about an hour out of Lake Tahoe, I am going to look into adding electric brakes to the second axle. On the negative side this new arrangement will impose a minimum boat ramp angle that I can launch from. One of the highlights of the trip for me was the dive we made on Tuesday together. I got a kick out of seeing your boat as we descended. I got one little video clip from Alec of us at about 100 ft. Hoping to get more.

Someone explained to me that in South America they are applauded for their on field dramatic performance. A bit like big time wrestling. I thought it was funny that they roll 10 times when they aren't touched but a World cup goalkeeper was jumped on by 10 of his team mates after a penalty shoot out & had no ill effects.

They had a transformer oil specially mixed for by Hoover vacuum cleaners. They apparently had a hell of a time, because carbon nodules would build up on the contacts and gum up the works. They ditched all of that sometime in the 80's when they went to brushless thrusters and now keep all of the high-power electronics in a titanium enclosure. What do you plan on using for thrusters?

And also its a lot bigger to keep in the garden! This is easier and more useful for other things. The idea is to just pick the sub up, move the trailer and put it on the beach. Wait for the tide. Big tides here so no problem with that. Collect in the opposite way. So forklift method works then!

One outside and one inside. The ASME welder was only going to charge me $120 for the weld using SP rods. Only problem is that The guy that I wanted to rent it to is wanting it all Kosher approved which I cant do with the CNG cylinder. I like your idea but the rods would need to be 4140 or such and could cost a bit by the time they are all machined up as my calc was about 20 rods 1? diameter approx.. But like everything you start on a project and the goal posts keep moving. I like the no welding approach though. Trust you to come up with that one. Thanks for the ideas.

You are so sensible but this is NZ. There are no parts in stock and the freight alone on a one off for the flange would cost a small fortune. We have looked all over and the closest we can do is one Sched 160 endcap which would need remachining inside. Class 900 RTJ flange was $650 class 1500 RTJ was $1500 but nothing else in NZ. The weight of an RTJ blank would be about 200 kg at a guess and trying to get reuse out of the joint ring would be a hassle. We could machine the flanges and put an O?ring in which would get around that issue. Because our Female prime minister caught Mad Cow Disease the oil exploration has ceased and Shell are firing all the kiwis all round the world in retaliation. SGS will still charge 1500 for a certificate on design and another 1000 for witnessing welding and pressure test. You can see what drives me crazy about this country.

I think you may have even recommended them. I just walked in the door & they designed it on the spot. Had it done & tested to 3000psi in no time. I am guessing it's for the guys at Oraki!

There are no parts in stock and the freight alone on a one off for the flange would cost a small fortune. We have looked all over and the closest we can do is one Sched 160 endcap which would need remachining inside. Class 900 RTJ flange was $650 class 1500 RTJ was $1500 but nothing else in NZ. The weight of an RTJ blank would be about 200 kg at a guess and trying to get reuse out of the joint ring would be a hassle. We could machine the flanges and put an O?ring in which would get around that issue. Because our Female prime minister caught Mad Cow Disease the oil exploration has ceased and Shell are firing all the kiwis all round the world in retaliation. SGS will still charge 1500 for a certificate on design and another 1000 for witnessing welding and pressure test. You can see what drives me crazy about this country.

Hello Mr. Pronk - this email is in regard to your question about using a submarine in Yellowstone Lake. We appreciate your interest in the lake and offer to collect samples, however in accordance with Federal regulations, the use of manned or unmanned submersibles may only occur in accordance with a permit. At this time we are not issuing permits for personal use of submersibles. If you'd like to learn more about the underwater research that has been conducted (by permit) in the lake you'll find a recent article fromEarth and Space Science News at this link.

From memory G.L. don't want you to have any external pods that can cause a catastrophic situation if they fail. I.e. if your battery pod fails you should have a large enough drop weight to counter it. Did you consider going for a number of smaller cylinders, as 600lb flotation is a lot to counter if one was ruptured.

Is there a difference in quality between the M100 & M105.? Do you know how many watts they both are? Is there a power jack for the M100? So you would just buy 2 M100 surface modules & they would communicate ok with each other? Below is additional info on the M105 I found in case anyone is interested. Thanks, Alan About This Product M100 G-DIVERS transceiver portable surface unit 1. Technical characteristics Main parts of the unit are: Battery housing: inside the battery housing there is a label with the serial number and the polarity to insert the battery. Battery should be a 9volt alkaline one, rechargeable batteries will last shorter. The autonomy with the alkaline battery (receiving mode) is around 30 hours with 30 minutes of low battery alarm (one ?beep? every 30 seconds)starting when voltage goes below 6.8volt. Antenna: It consist of a 10 meter cable directly connected to the main unit, at the bottom end there is the ceramic antenna, made to transmit and receive ultrasound to a frequency of 32.768 kHz. PTT button: it is a magnetic one, positioned right below the headset connector on the main unit Headset and microphone assembly with adjustable volume. Metal clip to attach the unit to the belt of the operator. 8 Pin plug to connect the headset with microphone.G.divers Communications unit manual rel.1.3 September 2010 17 2. Attaching the surface unit to the belt The M100 G.divers is designed to comfortable and easy to use. The main unit can be clipped to a belt or jacket, giving the operator an increased range of motion from other surface units. 3. Checking before use Once the battery has been installed and you have checked that the cap and cover have been closed properly, insert the headset with microphone in the plug on the main unit, the M100 G.divers will turn on automatically. You will hear a ?beep? indicating activation. Run a finger along the black cylinder at the bottom side of the antenna. You will hear a ?zzzzzz? type sound coming from the speaker. Try to bring the antenna transducer near the antenna on a M101A G.divers unit, or the antenna on a GSM G-Divers unit (about 5 cm / 2 inches). You should also be able to hear the communication when the unit is not immersed in water. If you hear a repeated ?beep? (about every 30 seconds) this means that the battery is running low. Change it. 4. Basic Instructions for communicate with divers underwater The following is the recommended operating procedure: Ensure the battery is properly installed with the correct polarity. Close the battery compartment. You can use some grease to make this operation easier. Attach the main unit to a secure place on your person such as a belt. Lower the transducer into the water. If you are on a boat, lower the transducer until it clears the hull. Under non circumstances should the transducer lie on the sea floor, this will reduce the signal strength and range. Connect the headset to the main unit, the unit turns on automatically upon connection. The unit is now in the receiving mode. To send a message push and hold the PTT button located on the main unit. After a short ?beep? you may begin speaking. When you release the button, the unit will return to receive mode. To improve the communication quality set the antenna the near as possible to diver?s depth. It is important that the transducer does not lay on the bottom When speaking to divers, keep in mind that they have a lot of things going on while underwater. It is better to have divers attention before starting the communication. Talk slowly and clearly Do not make long sentences. A good exercise is to make them repeat what they understood. CAUTION: Do not get the headset wet Do not put the unit underwater, it will not function as an underwater unit Do not attempt to keep the PTT button permanently depressed! You will not be able to receive messages from the divers and you may damage the unit.

I have seen an Ocean Reef unit Gsm G Power. They advertise a range from 500-1000ft. Is this able to be adapted for submarine use. I believe the transducer is attached to the unit so some hacking would be needed, to take it off & put it outside the hull.

You look like you are doing the same as me, taking the long route & building everything. I don't know how critical the potting is in this case but I once potted wires out of a linear actuator like you did, then filled the actuator up with WD40. It just ran out between the pvc & resin like magic with no pressure at all applied. On my light build I stripped a section of the wire that went through the epoxy, epoxied it & then went over the outside of the fitting & wiring with a 3M 2 part heat activated pvc glue. I went an inch up the wiring with this as this is how I noted they did it with vulcanising on underwater connectors.

It communicates with I2C. I think they have a board they sell with it. In your case, with your Arduino knowledge it would be easy to change the output to Fahrenheit. I have also heard that they are quite willing to modify products for you. Anyway you have a good temperature sensor now. I am always looking for off the shelf cheap solutions but sadly they are hard to come by in this field.

So you would just buy 2 M100 surface modules & they would communicate ok with each other? Below is additional info on the M105 I found in case anyone is interested. Thanks, Alan About This Product M100 G-DIVERS transceiver portable surface unit 1. Technical characteristics Main parts of the unit are: Battery housing: inside the battery housing there is a label with the serial number and the polarity to insert the battery. Battery should be a 9volt alkaline one, rechargeable batteries will last shorter. The autonomy with the alkaline battery (receiving mode) is around 30 hours with 30 minutes of low battery alarm (one ?beep? every 30 seconds)starting when voltage goes below 6.8volt. Antenna: It consist of a 10 meter cable directly connected to the main unit, at the bottom end there is the ceramic antenna, made to transmit and receive ultrasound to a frequency of 32.768 kHz. PTT button: it is a magnetic one, positioned right below the headset connector on the main unit Headset and microphone assembly with adjustable volume. Metal clip to attach the unit to the belt of the operator. 8 Pin plug to connect the headset with microphone.G.divers Communications unit manual rel.1.3 September 2010 17 2. Attaching the surface unit to the belt The M100 G.divers is designed to comfortable and easy to use. The main unit can be clipped to a belt or jacket, giving the operator an increased range of motion from other surface units. 3. Checking before use Once the battery has been installed and you have checked that the cap and cover have been closed properly, insert the headset with microphone in the plug on the main unit, the M100 G.divers will turn on automatically. You will hear a ?beep? indicating activation. Run a finger along the black cylinder at the bottom side of the antenna. You will hear a ?zzzzzz? type sound coming from the speaker. Try to bring the antenna transducer near the antenna on a M101A G.divers unit, or the antenna on a GSM G-Divers unit (about 5 cm / 2 inches). You should also be able to hear the communication when the unit is not immersed in water. If you hear a repeated ?beep? (about every 30 seconds) this means that the battery is running low. Change it. 4. Basic Instructions for communicate with divers underwater The following is the recommended operating procedure: Ensure the battery is properly installed with the correct polarity. Close the battery compartment. You can use some grease to make this operation easier. Attach the main unit to a secure place on your person such as a belt. Lower the transducer into the water. If you are on a boat, lower the transducer until it clears the hull. Under non circumstances should the transducer lie on the sea floor, this will reduce the signal strength and range. Connect the headset to the main unit, the unit turns on automatically upon connection. The unit is now in the receiving mode. To send a message push and hold the PTT button located on the main unit. After a short ?beep? you may begin speaking. When you release the button, the unit will return to receive mode. To improve the communication quality set the antenna the near as possible to diver?s depth. It is important that the transducer does not lay on the bottom When speaking to divers, keep in mind that they have a lot of things going on while underwater. It is better to have divers attention before starting the communication. Talk slowly and clearly Do not make long sentences. A good exercise is to make them repeat what they understood. CAUTION: Do not get the headset wet Do not put the unit underwater, it will not function as an underwater unit Do not attempt to keep the PTT button permanently depressed! You will not be able to receive messages from the divers and you may damage the unit.

You will hear a ?beep? indicating activation. Run a finger along the black cylinder at the bottom side of the antenna. You will hear a ?zzzzzz? type sound coming from the speaker. Try to bring the antenna transducer near the antenna on a M101A G.divers unit, or the antenna on a GSM G-Divers unit (about 5 cm / 2 inches). You should also be able to hear the communication when the unit is not immersed in water. If you hear a repeated ?beep? (about every 30 seconds) this means that the battery is running low. Change it. 4. Basic Instructions for communicate with divers underwater The following is the recommended operating procedure: Ensure the battery is properly installed with the correct polarity. Close the battery compartment. You can use some grease to make this operation easier. Attach the main unit to a secure place on your person such as a belt. Lower the transducer into the water. If you are on a boat, lower the transducer until it clears the hull. Under non circumstances should the transducer lie on the sea floor, this will reduce the signal strength and range. Connect the headset to the main unit, the unit turns on automatically upon connection. The unit is now in the receiving mode. To send a message push and hold the PTT button located on the main unit. After a short ?beep? you may begin speaking. When you release the button, the unit will return to receive mode. To improve the communication quality set the antenna the near as possible to diver?s depth. It is important that the transducer does not lay on the bottom When speaking to divers, keep in mind that they have a lot of things going on while underwater. It is better to have divers attention before starting the communication. Talk slowly and clearly Do not make long sentences. A good exercise is to make them repeat what they understood. CAUTION: Do not get the headset wet Do not put the unit underwater, it will not function as an underwater unit Do not attempt to keep the PTT button permanently depressed! You will not be able to receive messages from the divers and you may damage the unit. ? Sent from my iPad On 14/07/2018, at 10:23 AM, via Personal_Submersibles wrote: Alan, ?

Sorry just joking for actual political reason.. Maybe vibration of the steel destroy the saw? Or to fast rpm? With this kind of hole saw you can cut over 2inch deep in steel - if you can reach the center hole from both sides. But you need better two slow turning electric cable hand drills so one can cool down one during using the other. And cooling micture (oil/water or just oil) Hardest job I ever did was cutting 1 inch drop weight steel plates with a 120 mm small hand grinder just strait all together 8m long. Clear a job for a torch - but I had no one. vbr Carsten -----Original-Nachricht----- Betreff: Re: [PSUBS-MAILIST] hole saw Datum: 2018-07-16T11:55:58+0200 Von: "via Personal_Submersibles" An: "'Personal Submersibles General Discussion'" Boah.. the right speed and cutting oil I cutted holes in 15 mm P460 .

There should be no air bubbles or gaps between the transducer & the hull. I just looked at a 6" ID & 1/2" thick sphere in the Under Pressure program & it says 5,600ft crush depth for epoxy fibreglass. Of course depends a lot on a perfect layup, but encouraging results. If you put the transducer in a 6" sphere of fibreglass & filled around the transducer, inside, with resin or maybe chopped strands in resin, then it would be even stronger. You could mould the sphere in 2 halves, mount the transducer in one hemisphere, then glue the second on & fill with resin through the cable hole. You can test this out by going on the lake & putting your transducer in the water against a piece of fibreglass of the thickness & material you think you'll use, & see what depth it shows with & without the fibreglass up against it. If you had reasonable results at 1" thick another option may be mounting the transducer inside the hull & shooting through a small fibreglass viewport.

I am not sure about acrylic. You would have to attach the transducer to the acrylic unless you put the transducer in a bag full of water & had this forced against the acrylic. Again someone could try hanging the transducer in water while pushing it against a piece of acrylic. Alan In-Hull Transducers In-hull (a.k.a. shoot-through) transducers are epoxied directly to the inside of the hull. These are only used in fiberglass hulls. In-hulls will not work with wooden, aluminum, or steel hulls, or in foam sandwich/hulls that have air pockets. Any wood, metal, or foam reinforcement must be removed from the inside of the hull. With an in-hull transducer, the signal is transmitted and received through the hull of the boat. As a result, there is considerable loss of sonar performance. In other words, you won't be able to read as deep or detect fish as well with an in-hull transducer as with one that's transom mounted or thru-hull mounted. Fiberglass hulls are often reinforced in places for added strength. These cored areas contain balsa wood or structural foam, which are poor sound conductors. The transducer will need to be located where the fiberglass is solid and there are no air bubbles trapped in the fiberglass resin. You'll also want to make sure that there is no coring, flotation material, or dead air space sandwiched between the inside skin and the outer skin of the hull. Advantages No holes drilled in hull Excellent high speed performance No obstructions in the water Low maintenance Disadvantages Reduced maximuum depth reading Reduced fish detection Can only be used with fibreglass hulls Sent from my iPad > On 19/07/2018, at 1:52 PM, Jon Wallace via Personal_Submersibles wrote: > > > Can it shoot through acrylic? > > > From: hank pronk via Personal_Submersibles > To: Personal Submersibles General Discussion > Sent: Wednesday, July 18, 2018 6:55 PM > Subject: [PSUBS-MAILIST] depth sonar > > Hi all, > I am looking for ideas on how to make a depth transducer survive to 3,000 feet.

I believe the modern ones are potted. I have made enquiries about forward facing transducers locally in Auckland, where they do development work & testing on them. The enquiry was forwarded to the European transducer manufacturer who gave away nothing & said test at your own risk.

You could buy something with a 20 meter range & could set an alarm at a certain distance. I am not sure how this would work in murky conditions! Be easy to find out by diving. If the reading diminished with murkiness then perhaps have an additional range finder pointed at an object on the sub exactly 1 metre away, & use it's readings to continually calibrate the main laser. There are a few people on this site that could easily do that with arduino.

In cave diving they have a narrow beam as well as a wide beam for spotting things like cave walls off in he distance. If you had a narrow beam pointed down it may be a good backup in case the sonar failed.

You would have to attach the transducer tothe acrylic unless you put the transducer in a bag full of water & had thisforced against the acrylic.?Again someone could try hanging the transducer in water while pushing it?against a piece of acrylic.Alan In-Hull Transducers In-hull (a.k.a. shoot-through) transducers are epoxied directly to the inside of the hull. These are only used in fiberglass hulls. In-hulls will not work with wooden, aluminum, or steel hulls, or in foam sandwich/hulls that have air pockets. Any wood, metal, or foam reinforcement must be removed from the inside of the hull. With an in-hull transducer, the signal is transmitted and received through the hull of the boat. As a result, there is considerable loss of sonar performance. In other words, you won't be able to read as deep or detect fish as well with an in-hull transducer as with one that's transom mounted or thru-hull mounted. Fiberglass hulls are often reinforced in places for added strength. These cored areas contain balsa wood or structural foam, which are poor sound conductors. The transducer will need to be located where the fiberglass is solid and there are no air bubbles trapped in the fiberglass resin. You'll also want to make sure that there is no coring, flotation material, or dead air space sandwiched between the inside skin and the outer skin of the hull. Advantages - No holes drilled in hull - Excellent high speed performance - No obstructions in the water - Low maintenance Disadvantages - Reduced maximuum depth reading - Reduced fish detection - Can only be used with fibreglass hulls Sent from my iPad On 19/07/2018, at 1:52 PM, Jon Wallace via Personal_Submersibles wrote: Can it shoot through acrylic?

I have 640 GB of footage. However, it is all 4K and although that is a really good thing, it also makes it impractical to share the raw files due to their size. A lot of the footage was passively shot with Gopros, so you have half an hour of blue water on the other side of a viewport and perhaps 30 seconds (or nothing at all) of something happening - very different to what you get with a human operator. Since I went almost directly from Tahoe to a second adventure (a race in Indianapolis) I finally began editing only yesterday. Hopefully I can have something in about 2-3 weeks, although that's a bit flexible. My impression is that the image and sound quality came out really good, but that there isn't enough of a story or drama for a film that would be of interest to the general public. We'll probably end up with a 10 minute piece showing that PSUBS really can be used for science, and which might be very useful for showing to additional scientists considering collaborations with us, even if not quite engaging enough to be the next Netflix breakout.

You would have to attach the transducer tothe acrylic unless you put the transducer in a bag full of water & had thisforced against the acrylic.?Again someone could try hanging the transducer in water while pushing it?against a piece of acrylic.Alan In-Hull Transducers In-hull (a.k.a. shoot-through) transducers are epoxied directly to the inside of the hull. These are only used in fiberglass hulls. In-hulls will not work with wooden, aluminum, or steel hulls, or in foam sandwich/hulls that have air pockets. Any wood, metal, or foam reinforcement must be removed from the inside of the hull. With an in-hull transducer, the signal is transmitted and received through the hull of the boat. As a result, there is considerable loss of sonar performance. In other words, you won't be able to read as deep or detect fish as well with an in-hull transducer as with one that's transom mounted or thru-hull mounted. Fiberglass hulls are often reinforced in places for added strength. These cored areas contain balsa wood or structural foam, which are poor sound conductors. The transducer will need to be located where the fiberglass is solid and there are no air bubbles trapped in the fiberglass resin. You'll also want to make sure that there is no coring, flotation material, or dead air space sandwiched between the inside skin and the outer skin of the hull. Advantages - No holes drilled in hull - Excellent high speed performance - No obstructions in the water - Low maintenance Disadvantages - Reduced maximuum depth reading - Reduced fish detection - Can only be used with fibreglass hulls Sent from my iPad On 19/07/2018, at 1:52 PM, Jon Wallace via Personal_Submersibles wrote: Can it shoot through acrylic?

The 12V were not direct acting, they needed some pressure in the system to open. You probably already know this but mentioning it just in case. You won't have enough pressure in your ballast system for them to operate if they aren't direct acting. There is some other alternative terminologies for them that I have forgotten. I know you will be excited about this, but you can buy a cheap piece of electronics that they use on quad copters with a gyro on it. Hook it up to an arduino board, with relays from it controlling your solenoids. Write a bit of code & at the flick of a switch it could automatically control the ballast valves so you descend level.

Regrettably I have been quite neglectful of performing much upkeep on the sub, save for keeping the batteries topped off. My schedule is finally allowing me to spend some real time working on the sub and getting to know the specifics of each system. As you can imagine, I've been bugging Alec with a question here and there, but thought with this topic I should start a discussion here on the list for the benefit of anyone else who might have questions / curiosities about mechanical depth gauges. Snoopy's depth gauge is nice and large (about 5" in diameter) so it's easy to read. Alec created a nice label for the gauge face which reads from 0 to 300 (in feet) with the last fifty feet being marked in red to indicate 'too deep.' Problem is, when I looked at the depth gauge the other day, I noticed that the transparent cover plate on the gauge looked to be quite opaque (to the point where I couldn't quite read the numbers or count the hash marks). I assumed that there was some moisture trapped in the gauge, causing the obscuration. I decided to remove the gauge from the sub and open it up to let it dry out. After removing the gauge from the sub, I unscrewed three small screws around the bezel and popped off the transparent cover plate. It was only then that I realized the opaqueness was not caused by moisture but a distortion in the clear plastic. The distortion (like super fine scratches) appears to be on the outside of the cover, as though it was cleaned by something that started to melt the plastic or was left out in the sun too long. I don't think either of these explanations make sense, but I'm puzzled as to what might have caused it. I might try to buff / polish the plastic, or perhaps just replace it with glass. I think it's a good idea to stick a dive computer in viewing range of a viewport for a depth reading, but I like the idea of having a mechanical gauge in the sub as well. A couple of questions that come to mind: what is the pressure variation between salt water and fresh water? Also, although I didn't find moisture in the gauge, The label on the face is wrinkled a bit as though it has seen moisture. Although water should never actually reach the gauge, I can see how moisture from the inlet tube could find its way up into the gauge body. Should I be concerned about drying it out somehow after a dive (especially in salt water)? If so, how should I go about it? ~ Doug S.

Never thought of that. No there was no gasket or anything, so I guess any moisture in the viewing portion of the gauge would just come from moisture inside the hull of the sub. And thank you for the pressures... not a huge difference but I suppose at deep depths it could work out to be somewhat of an error.

The gauge then only sees oil not sea water. Gauges with electronic displays & the ability to flick between metric, imperial, psi, mpa etc are pretty cheap. I have a dwyer gauge ( somewhere). Being a young person you may want to go down the route of buying a gauge that you can attach to an arduino, then electronically display on a board as big as you like!

It's a tiny computer board that is designed to interact with the environment. Ie. you might have various sensors like pressure, motion, light, or a switch etc that send a signal into the arduino & the arduino outputs some action depending on the program you write & the outputs you add to it. It is used a lot in robotics. The programming language is reasonably simple & designed for beginners & hobbyists. My local electronics store has a couple of stands full of sensors etc for it. There are a number of arduino boards, uno, mega, duo etc. It is like the raspberry pi but not as powerful. There are other more powerful boards than raspberry pi on the market. If you bought a pressure sensor with a 4-20ma or 0-5V output you could wire it to the arduino board & calibrate that signal into a depth range that is outputed to an led screen, and also sets off an alarm at a certain depth. There are good on line courses on it on UDEMY. I was going to buy a plc ( industrial computer) but are now going to do everything with arduino, raspberry pi etc. Jon, Cliff & others are a lot more competent than I am with this, so there would be plenty of help if you wanted to go that route.

I looked on my laptop and sure enough found a simple 2D CAD file called "Depth gauge faceplate." So here you go, I'll paste a screen shot below so you can print it. It's black and white, and the red was I think just done with a marker over the hatch pattern. Looking at this, the "250" is not quite straight, but when printed at the scale of the instrument I don't recall noticing it. So... just try printing this a few times until you get the scale right, then cut out with scissors and then paste right onto the instrument. That's all there is to it. Concerning the question about whether the instrument sees water, here's an explanation for everyone else. The pressure gauge is in the CT, high in the boat, but the line that feeds it pressure comes into the hull at close to the lowest point. It is open to the sea, and as you dive the air in the line will of course compress. It will not, however, ever compress enough that the sea water actually reaches the instrument. The gauge measures the difference between inlet pressure and ambient, so the instrument case is not sealed or it would establish a reference pressure. There is an opening in the case in order to equalize pressure, and as I recall a little filter element intended to keep dust out but let air through. It will let in cabin humidity too, which in places like the keys probably means you'll print a new paper face-plate from time to time.

It went straight to the printer. On a couple of our outings the support boats coms have been chopped by propellers. I know it happened in Islamorada & think it happened at Lake Tahoe. What about using a down-rigger on the support boat like they use for fishing to keep the line low while trolling. That could keep the transducer cable away from the prop.

I would have to put hemispherical end caps in the equation as thats it's limit. You might get a better offer from someone with a better program but I am sure I could get you in the ball park.

For each pod, I'm showing a weight of 308 pounds and displacement of 410 pounds resulting in 102 pounds of positive buoyancy.? Your battery weight and lead weight totals 258 pounds which then makes each pod 156 pounds negative buoyant. Your batteries seem light.? Most batteries I've seen in USA are about 27 kg.? For comparison, each pod of a K-350 is 235 pounds with displacement of 204 pounds making it 31 pounds negative bouyant.? Four batteries at 60 pounds increases negative buoyancy to 271 pounds. Bottom line is that if you are top heavy you need more weight low to counter act it.? I agree with Hank in that you have a lot of weight at the top in your soft ballast tank design.? You can see that a typical K-350 design has 230 pounds more weight (both pods total) than Casper2 and it's ballast tanks are designed to be both smaller and fabricated from fiberglass.? So more weight at bottom, less at top. Additionally, consider that my K-600 which has the same battery pod and ballast tanks of the K-350, had 240 pounds of lead weight as ballast in-between the ribs of the pressure hull.? My point being that it takes a lot of weight in some cases. I think that if you don't want to redesign your main ballast tanks, just keep pumping lead weight into the battery pods and as low as possible in the main pressure hull until you get it stable.? Obviously this is going to increase your overall vessel weight which may result in other modifications in terms of trailering or launch/recovery. Not sure why Casper2 doesn't show on the web site when searching by name, but it does show up if you search by submitter under Graham Bayliss.?

I did the calculations for fresh water & with carbon steel. Old end caps in air 24lb in water 20.9lb x 2 Old cylinder in air 429lb in water 190.32. So 190.32 + 41.8 = 232.12 heavy for the old pod in water. Am ignoring the battery weight as you say they are the same in both pods. New end caps in air 21.8lb in water 19lb x 2 New cylinder in air 229lb in water -189.71lb So -189.71lb + 38lb = -151.71lb buoyant for the new pod in water. You need 151.71 + 232.12 = 383.83lb ( difference of weight in water between old & new pod) extra lead to get you to the neutrally buoyant state. Hope that's right.

It comes down to adding buoyancy up high and weight down low. I too have batteries inside cylindrical pods. One of the cheapest and easiest ways to add low weight is to cut long steel bars and slide them into the V shaped spaces between the batteries and the sides of the pod. If you weld a nut to the end of each bar you can easily slide them out using a bolt as a temporary handle. Make sure the bars don't have a way to jump up and short out the battery terminals when bouncing along on a trailer. In my case the upper edge of the batteries is touching the wall of the pod so there is no way for the bars to get on top of the batteries. A cheap way to add high buoyancy is using trawl floats.

I don't see the lead, but I do see some brackets on top of the pods so I'm guessing that's where it goes. You want that lead absolutely as low as you can locate it -- more like at the bottom of the pods. Perhaps in the space between the pods, where you probably have the drop weight? You'll find that moving 150 lbs down about a foot like that will make a considerable difference.

Destination was a weigh station about 20 miles away and the empty submarine came in at 3065 pounds.? Towing was effortless EXCEPT: Attached is a photo of the suspension equalizer.? The front axle is left, rear axle right.? The submarine placement needs to be almost directly over the front axle in order to get a decent tongue weight of about 10% to prevent sway while towing.? However, you can see that the front side of the suspension equalizer is quite a bit higher than the rear, and after dynamic loading on the road (going over a pothole or two) that spring eye and shackle actually "tops out" or sits against the trailer frame making for a very rough trailer ride. If I placed the bulk of the submarine over the mid-point between the two axles, theoretically to spread the load equally between them, I would essentially have no tongue weight so I don't see that as an option.? I could always add some extra weight at the front to get some tongue weight but dive ready I will be close to the weight limit of the sub and trailer so may not have much wiggle room for extra additional weight. Other options?? The shackles are 3.5 inch long, which is longer than a typical shackle, but I think designed that way to get the trailer frame as low to the ground as possible.? I could shorten the shackles to provide more head room between the spring eye and the trailer frame but I hate to do that work only to find out that it isn't enough and the equalizer just cocks more to the front and allows the spring eye to reach the frame again.? It would also end up raising the trailer higher overall which I want to avoid if I can, for purposes of launch and recovery. I thought about stronger leaf springs but I don't think the springs are the problem.? The problem is that the load is primarily concentrated on the front axle and the equalizer allows the spring to pivot, to compensate.? So I don't see stronger springs preventing this. I have also thought about "locking" the equalizer in place which would subvert the purpose of the equalizer.

Destination was a weigh station about 20 miles away and the empty submarine came in at 3065 pounds.? Towing was effortless EXCEPT: Attached is a photo of the suspension equalizer.? The front axle is left, rear axle right.? The submarine placement needs to be almost directly over the front axle in order to get a decent tongue weight of about 10% to prevent sway while towing.? However, you can see that the front side of the suspension equalizer is quite a bit higher than the rear, and after dynamic loading on the road (going over a pothole or two) that spring eye and shackle actually "tops out" or sits against the trailer frame making for a very rough trailer ride. If I placed the bulk of the submarine over the mid-point between the two axles, theoretically to spread the load equally between them, I would essentially have no tongue weight so I don't see that as an option.? I could always add some extra weight at the front to get some tongue weight but dive ready I will be close to the weight limit of the sub and trailer so may not have much wiggle room for extra additional weight. Other options?? The shackles are 3.5 inch long, which is longer than a typical shackle, but I think designed that way to get the trailer frame as low to the ground as possible.? I could shorten the shackles to provide more head room between the spring eye and the trailer frame but I hate to do that work only to find out that it isn't enough and the equalizer just cocks more to the front and allows the spring eye to reach the frame again.? It would also end up raising the trailer higher overall which I want to avoid if I can, for purposes of launch and recovery. I thought about stronger leaf springs but I don't think the springs are the problem.? The problem is that the load is primarily concentrated on the front axle and the equalizer allows the spring to pivot, to compensate.? So I don't see stronger springs preventing this. I have also thought about "locking" the equalizer in place which would subvert the purpose of the equalizer.

I'm doing pretty well with my tongue weight setup using a bathroom scale.? When I think I've got it where I want it I go to a CAT scale about 20 miles away and confirm everything that way.
