Specifically, the cabin has to adjust to the pressure change. A major issue if descending quickly is that your ballast/cabin air volume must be able to keep up with the pressure increase. If not the cabin will either flood or crush, depending on your design. Usually if ascending quickly the excess cabin air is easily vented, but this too needs to be able to keep up with the decrease in pressure. I invite you to watch the video of my second dive in my SportSub semi-dry ambient submarine. You may be aware that in this submarine the occupants are sitting or kneeling in waist deep water. The cabin air bubble above the moon pool is also the trim ballast tank. In the video my son and I are sitting lightly on the bottom when he exits the submarine out the back hatch. His volume in the airspace above the moon pool is immediately taken up by water, raising the level of the moon pool. The electronic buoyancy control notices the increase in the water level and immediately adds air to the cabin to lower the water level to where it was set. Without my son's weight in the airspace the sub is now positively buoyant and heads for the surface. As I pop to the surface you can see him signally me to submerge since the whole point of him exiting the sub was to take video of the sub on the bottom. So, down I go, and end up bouncing off the bottom. Hey, it was only my second time piloting this thing. In the next part of the video I have raised the moon pool as high as possible to sit hard on the bottom, and have also turned off the EBC. When I exited, the slug of water taking up my volume raised the moon pool level further such that it was lapping at the instrument panel. That time the sub stayed on the bottom, happily. www.youtube.com/watch?v=YIoGhDKOQc8 One feature of a wet submarine is that you can trim the buoyancy with weights prior to the dive, then expect very little buoyancy changes while you descend and ascend. This will result in much less air being used compared with dry or semi-dry ambient. Best of luck with your project, whether it be 1atm or ambient. Hmmm, there are two submarines for sale on Miami Craigslist, a 1atm and a SportSub 3. Both have been there quite a while.

On Emile's sub, that has rotating thrusters, he can sit perfectly still an inch above a wreck. I would go the wet sub or DPV route first off. You can just buy a trolling motors & air compensate them off an octopus regulator. You will have the experience of water proofing your electronics, soughting out controllers & ballasting. That will keep you busy for a while. I have been thinking of building a DPV / wet sub so that I can get the tank off my back & scoot around without getting cramp :) Maybe with a coiled breathing hose long enough to get in to some crayfish holes. The dry ambient can certainly be cheaper than a 1atm, especially if you want large hemispherical view ports.

Instead of building a dry sub, maybe I should be looking into a wet sub. Has anyone here attempted building a wet sub before?

It had a jet unit out back that rotated for steering, & dive planes. Cliff has now taken off the jet unit & gone to two horizontal & two vertical thrusters. Graham Hawke's latest sub "The Dragon" has horizontal & vertical thrusters. I met one of Hawke's previous business partners who has now partnered with Nuytco to develop the Orcasub. He didn't like the "Deep Flight" flying concept & didn't think it worked well. Orcasub link below. http://nuytco.com/products/orcasub/ The Falcon might be OK in 200ft visibility water, but has lack of manouverability for normal conditions. Additionally, as you are building an ambient, which is not as safe as a 1atm, it is handy to have two horizontal thrusters to compensate for any sudden buoyancy changes. Have a friend that dived in the Falcoln in Fiji. He said it was really hot on the surface & remained hot under the water. It has a composite hull, so not much heat transfer. With your breathing air coming in at 20 liters a minute in an ambient, it does cool you a bit.

He had the acrylic set up so that the pressure was pushing against the glue & not the frame. I didn't think this was wise, as it could be fatal if the glue failed. Acrylic scratches easily & is not as impact resistant as fiberglass. Your submarine has to weigh as much as the water displaced to be neutrally bouyant. Imagine your hull being a solid block of ice, & you will get a picture of the weight involved. The owner of the "dry dive" told me he hit a pinacle under the water & it was a massive impact even at slow speed. So build for strength. I would imagine acrylic of the thickness you need would be quite expensive. There are a couple of manufacturers in the States that sell acrylic domes at reasonable prices in varying sizes & up to I think 10mm thick. The domes for 1atm subs can cost thousands. If you want to post an image of your ideas we could comment on it. I am getting the impression you are wanting to build something like a fish tank! Even a pencil drawing will do.

The Minn kotta 101 is a popular model for this. Cliff Redus has done a modification of one on his psub project page. I bought 4 cheap Chinese electric trolling motors for my dry ambient, 2 x 300W & 2 x 200W, but when I pulled them apart I found the quality was dubious. Most of these trolling motors are brushed dc. I am making my own brushless dc thrusters. They run off dc but can be categorized as AC as the motor controller sends an alternating current to the motor coils. A typical set up is to have two horizontal thrusters & two vertical thrusters. Or just 2 horizontal thrusters that rotate. Like this semi-dry ambient.. http://www.fugusub.com/ The steering is "tractor steering", more power on one than the other turns you. 3 knots is regarded as a reasonable speed for a submersible underwater. If you double your speed you quadriple your energy consumption, so no need to overpower it. Two 101s seem to push a K250 along quite well. The seals in the 101 are rated to about 15ft but have been known to keep water out at 100ft. Most people either air compensate or oil compensate them so the pressure inside the motor housing is equal to the water pressure outside. This enables you to go quite deep. Karl Stanley goes to 2000ft on air compensated thrusters. In his set up he uses a first stage regulator that he has taken the spring out of, to give him ambient pressure. Then he lets over expansion of air on the way up exhaust out the motor seal. (not good) I air compensated mine with air coming down the wiring tube from a 2nd stage regulator. With an ambient you could use the cabin pressure to compensate the motors. Just have tube from your motor to the hull, with the wires running down it. (cheap) I prefer oil compensation for cooling of the motor, lubrication of the seals & bearings as well as some added protection against water ingress. This is easy to do in your case, as you could fill the motor with oil & have the air compensation / wiring tube higher than the motor. The ambient air pressure keeps the oil pressurized. A battery pod seems a good idea, as compensating batteries can be a hasle.

If you look at my build on psubs you can see the strips of mdf inside circular cut outs. I fiber glassed the inside of the strips (stringers) then broke off the circular cut outs. MDF is not the smartest material to use, but I retrospectively decided to make an ambient out of my model. The process worked well, but I would use marine ply. Ply wood is used in fiberglass sandwiches to give strength. Doug's ambient "Argonaut Junior" is made of marine ply. (Not the Doug that replied to you). Using ply should save you on cost. I would mix a suitably hard filler with the resin to go between the gaps of the stringers. You can see in one picture that I used an exercise ball for the back round section. I greased the ball with Vaseline then stuck plastic kitchen wrap to it, then fiberglass. If you do this, be warned that the volume of the ball changes with the temperature. If you go this path, I would advise that you work out exactly what you need, buy the parts, make sure they fit in a model, then build. This is very difficult to do as the temptation is to build the hull so you can see some progress. Glad you bought the book; just about everyone on this site would recommend that as a first step.

Doug had one on his Arganaut junior. http://svseeker.com/argonaut_jr_2010.htm He had an "incident" because of it. He surfaced with the moon pool open & the bouncing motion as he broke the surface & went back down again, compressed the air in his hull through the moon pool. This made him negatively bouyant & caused him to descend. As he descended there was more compression of the air and an increasing negative buoyancy. Before he knew it he was on the bottom, which fortunately was only 20ft down. This could have been a fatality if he had been over deep water. You will find it difficult attaching everything you need to a plastic pipe. I imagine it would be difficult to glue & attach to securely. It's your life at stake. Epoxy / Fiberglass isn't cheap, but it's easy to add things to, drill holes through & attach through hulls, fit your hatch landing to etc. The join is just as strong if you want to add to it retrospectively, as apposed to the cheaper polyester resin.

So not a lot of structural strength needed other than to support the lead you are going to need & scuba tanks. All the electronics will need to be water & pressure proof. It is mainly the large capacitors that are vulnerable to pressure & you find these predominantly in the motor controllers. Don't ask me what pressure they fail at, I have just read that from other posts, & all capacitors are not the same. There are those little scooters that just keep your head dry that could be regarded as a semi-dry. I would be worried about a runaway situation with a semi-dry; where you couldn't keep the air volume at the correct level & as you descended it would compress even more. I guess you have vertical thrusters to counter that. Not a lot more strength required for a dry ambient. A dry ambient will need a conning tower, as with other submarines. If you build as per my design or Cliff's R300, you will find it hard to get in without taking in water in mildly rough conditions.

With the life support air flowing in at 20 liters a minute, this tends to equalize the hull, & any overpressure goes out the regulator exhaust ports. Supplementary air is automatically provided by the regulators. There are other ways that people use. I can elaborate if you go that path.

Bear in mind that I am a novice PSUBBER, but I'll give you my two cents on your situation: If you are a scuba diver and comfortable diving ambient, go for a wet or semi-dry sub, not full on dry ambient. I say this because there are still an infinite number of learning opportunities with a wet sub, but you aren't dealing with the ballast weight needed to sink an entire air-filled hull. If you really want to go dry, go one atmosphere. If you are going to be leaving the states in 18-24 months, a wet sub (like a DPU / scooter or a bubble sub) seems like it's just the ticket... whatever you decide, good luck on your journey.

You are only ambient at a certain point between the bottom of your hull & the top. Everything below this point is under external pressure & everything above is under internal pressure. This can put a lot of internal force on the hatch. To visualize it, mentally flip your sub upside down and fill it with water to ambient point. The weight of water on your hatch will be equivalent to the internal air pressure on it when diving. There are modifications to the batteries that need doing if you want them in the hull, as they typically crush at about 15ft. You have 20 liters of air per person flowing in to the hull for life support plus the air for equalization, which is 4 x the volume of your sub at 100ft. So a lot of air needed. You need to watch that any electronics can handle the pressure you are diving to.

I also did find out about the issues regarding ambient subs which is why I am going to just go for a 1 atm sub. I'm going to hold of building until I move and use the time beforehand to learn as much as I can because I don't want to go rushing in building a sub and making major mistakes. -Ludwig -----Original Message----- From: T Novak via Personal_Submersibles To: 'Personal Submersibles General Discussion' Sent: Sun, Jan 1, 2017 6:30 pm Subject: Re: [PSUBS-MAILIST] Looking at starting up a Submersible project HI Ludwig, Your question "besides your ears having to adjust to the pressure change, am I forgetting something?" has a few answers that you may find noteworthy while designing and building a dry ambient submarine. Specifically, the cabin has to adjust to the pressure change. A major issue if descending quickly is that your ballast/cabin air volume must be able to keep up with the pressure increase. If not the cabin will either flood or crush, depending on your design. Usually if ascending quickly the excess cabin air is easily vented, but this too needs to be able to keep up with the decrease in pressure. I invite you to watch the video of my second dive in my SportSub semi-dry ambient submarine. You may be aware that in this submarine the occupants are sitting or kneeling in waist deep water. The cabin air bubble above the moon pool is also the trim ballast tank. In the video my son and I are sitting lightly on the bottom when he exits the submarine out the back hatch. His volume in the airspace above the moon pool is immediately taken up by water, raising the level of the moon pool. The electronic buoyancy control notices the increase in the water level and immediately adds air to the cabin to lower the water level to where it was set. Without my son's weight in the airspace the sub is now positively buoyant and heads for the surface. As I pop to the surface you can see him signally me to submerge since the whole point of him exiting the sub was to take video of the sub on the bottom. So, down I go, and end up bouncing off the bottom. Hey, it was only my second time piloting this thing. In the next part of the video I have raised the moon pool as high as possible to sit hard on the bottom, and have also turned off the EBC. When I exited, the slug of water taking up my volume raised the moon pool level further such that it was lapping at the instrument panel. That time the sub stayed on the bottom, happily. www.youtube.com/watch?v=YIoGhDKOQc8 One feature of a wet submarine is that you can trim the buoyancy with weights prior to the dive, then expect very little buoyancy changes while you descend and ascend. This will result in much less air being used compared with dry or semi-dry ambient. Best of luck with your project, whether it be 1atm or ambient. Hmmm, there are two submarines for sale on Miami Craigslist, a 1atm and a SportSub 3. Both have been there quite a while.

I had the chance to visit Scott's workshop on Monday and had the change to take a look at Trustworthy, and what I notice was that it's quite cramp inside of the sub. I was talking with Scott and he mentioned increasing the diameter from 36 inches to 42 inches. Has anyone done it before?

On Emile's sub, that has rotating thrusters, he can sit perfectly still an inch above a wreck. I would go the wet sub or DPV route first off. You can just buy a trolling motors & air compensate them off an octopus regulator. You will have the experience of water proofing your electronics, soughting out controllers & ballasting. That will keep you busy for a while. I have been thinking of building a DPV / wet sub so that I can get the tank off my back & scoot around without getting cramp :) Maybe with a coiled breathing hose long enough to get in to some crayfish holes. The dry ambient can certainly be cheaper than a 1atm, especially if you want large hemispherical view ports.

Instead of building a dry sub, maybe I should be looking into a wet sub. Has anyone here attempted building a wet sub before? Does anyone here know if there are any vlog (video blog) type videos on submarines/submersibles? There are a lot of vlogs over flying, sailing and other activities and I'm thinking that the submarine community could benefit from it because it will help promote the sport/activity. -Ludwig -----Original Message----- From: emile via Personal_Submersibles To: 'Personal Submersibles General Discussion' Sent: Sat, Dec 3, 2016 3:49 pm Subject: Re: [PSUBS-MAILIST] Looking at starting up a Submersible project Hi Alan, Yep, You need air-conditioning in warm waters and a composite hull.

It had a jet unit out back that rotated for steering, & dive planes. Cliff has now taken off the jet unit & gone to two horizontal & two vertical thrusters. Graham Hawke's latest sub "The Dragon" has horizontal & vertical thrusters. I met one of Hawke's previous business partners who has now partnered with Nuytco to develop the Orcasub. He didn't like the "Deep Flight" flying concept & didn't think it worked well. Orcasub link below. http://nuytco.com/products/orcasub/ The Falcon might be OK in 200ft visibility water, but has lack of manouverability for normal conditions. Additionally, as you are building an ambient, which is not as safe as a 1atm, it is handy to have two horizontal thrusters to compensate for any sudden buoyancy changes. Have a friend that dived in the Falcoln in Fiji. He said it was really hot on the surface & remained hot under the water. It has a composite hull, so not much heat transfer. With your breathing air coming in at 20 liters a minute in an ambient, it does cool you a bit.

He had the acrylic set up so that the pressure was pushing against the glue & not the frame. I didn't think this was wise, as it could be fatal if the glue failed. Acrylic scratches easily & is not as impact resistant as fiberglass. Your submarine has to weigh as much as the water displaced to be neutrally bouyant. Imagine your hull being a solid block of ice, & you will get a picture of the weight involved. The owner of the "dry dive" told me he hit a pinacle under the water & it was a massive impact even at slow speed. So build for strength. I would imagine acrylic of the thickness you need would be quite expensive. There are a couple of manufacturers in the States that sell acrylic domes at reasonable prices in varying sizes & up to I think 10mm thick. The domes for 1atm subs can cost thousands. If you want to post an image of your ideas we could comment on it. I am getting the impression you are wanting to build something like a fish tank! Even a pencil drawing will do.

Anyways, what I really wanted to ask was has anybody tried using Acrylic Sheets on an ambient sub?

The Minn kotta 101 is a popular model for this. Cliff Redus has done a modification of one on his psub project page. I bought 4 cheap Chinese electric trolling motors for my dry ambient, 2 x 300W & 2 x 200W, but when I pulled them apart I found the quality was dubious. Most of these trolling motors are brushed dc. I am making my own brushless dc thrusters. They run off dc but can be categorized as AC as the motor controller sends an alternating current to the motor coils. A typical set up is to have two horizontal thrusters & two vertical thrusters. Or just 2 horizontal thrusters that rotate. Like this semi-dry ambient.. http://www.fugusub.com/ The steering is "tractor steering", more power on one than the other turns you. 3 knots is regarded as a reasonable speed for a submersible underwater. If you double your speed you quadriple your energy consumption, so no need to overpower it. Two 101s seem to push a K250 along quite well. The seals in the 101 are rated to about 15ft but have been known to keep water out at 100ft. Most people either air compensate or oil compensate them so the pressure inside the motor housing is equal to the water pressure outside. This enables you to go quite deep. Karl Stanley goes to 2000ft on air compensated thrusters. In his set up he uses a first stage regulator that he has taken the spring out of, to give him ambient pressure. Then he lets over expansion of air on the way up exhaust out the motor seal. (not good) I air compensated mine with air coming down the wiring tube from a 2nd stage regulator. With an ambient you could use the cabin pressure to compensate the motors. Just have tube from your motor to the hull, with the wires running down it. (cheap) I prefer oil compensation for cooling of the motor, lubrication of the seals & bearings as well as some added protection against water ingress. This is easy to do in your case, as you could fill the motor with oil & have the air compensation / wiring tube higher than the motor. The ambient air pressure keeps the oil pressurized. A battery pod seems a good idea, as compensating batteries can be a hasle.

If you look at my build on psubs you can see the strips of mdf inside circular cut outs. I fiber glassed the inside of the strips (stringers) then broke off the circular cut outs. MDF is not the smartest material to use, but I retrospectively decided to make an ambient out of my model. The process worked well, but I would use marine ply. Ply wood is used in fiberglass sandwiches to give strength. Doug's ambient "Argonaut Junior" is made of marine ply. (Not the Doug that replied to you). Using ply should save you on cost. I would mix a suitably hard filler with the resin to go between the gaps of the stringers. You can see in one picture that I used an exercise ball for the back round section. I greased the ball with Vaseline then stuck plastic kitchen wrap to it, then fiberglass. If you do this, be warned that the volume of the ball changes with the temperature. If you go this path, I would advise that you work out exactly what you need, buy the parts, make sure they fit in a model, then build. This is very difficult to do as the temptation is to build the hull so you can see some progress. Glad you bought the book; just about everyone on this site would recommend that as a first step. Pleased to help with your future build.

Initially I was making a model out of mdf, & decided to fiberglass it & make an ambient. I just intuitively added layers till I felt it was strong enough. I used epoxy / fiberglass, so I didn't have to lay it up in one shot. Items like the ballast tanks I formed out of polystyrene, glassed over the top & disolved out the polystyrene with petrol. On my current build I am using Rhino 5 & Orca. On my ambient I made an initial model out of chicken wire. No design programs.

Doug had one on his Arganaut junior. http://svseeker.com/argonaut_jr_2010.htm He had an "incident" because of it. He surfaced with the moon pool open & the bouncing motion as he broke the surface & went back down again, compressed the air in his hull through the moon pool. This made him negatively bouyant & caused him to descend. As he descended there was more compression of the air and an increasing negative buoyancy. Before he knew it he was on the bottom, which fortunately was only 20ft down. This could have been a fatality if he had been over deep water. You will find it difficult attaching everything you need to a plastic pipe. I imagine it would be difficult to glue & attach to securely. It's your life at stake. Epoxy / Fiberglass isn't cheap, but it's easy to add things to, drill holes through & attach through hulls, fit your hatch landing to etc. The join is just as strong if you want to add to it retrospectively, as apposed to the cheaper polyester resin.

So not a lot of structural strength needed other than to support the lead you are going to need & scuba tanks. All the electronics will need to be water & pressure proof. It is mainly the large capacitors that are vulnerable to pressure & you find these predominantly in the motor controllers. Don't ask me what pressure they fail at, I have just read that from other posts, & all capacitors are not the same. There are those little scooters that just keep your head dry that could be regarded as a semi-dry. I would be worried about a runaway situation with a semi-dry; where you couldn't keep the air volume at the correct level & as you descended it would compress even more. I guess you have vertical thrusters to counter that. Not a lot more strength required for a dry ambient. A dry ambient will need a conning tower, as with other submarines. If you build as per my design or Cliff's R300, you will find it hard to get in without taking in water in mildly rough conditions.

I extended the exhaust ports down to stop water coming in. With the life support air flowing in at 20 liters a minute, this tends to equalize the hull, & any overpressure goes out the regulator exhaust ports. Supplementary air is automatically provided by the regulators. There are other ways that people use. I can elaborate if you go that path.

You enter from underneath (& get wet) & the top of your torso is above water. It has the advantage of being lighter than a dry ambient, but is more complex in that you are sitting in a bubble that continually compresses as you descend & expands as you ascend, & needs to be kept at it's initial dive volume to maintain the same level of buoyancy.

You will definitely find some awesome, informative people here who can help you answer questions and make design / fabrication decisions along the way.

Bear in mind that I am a novice PSUBBER, but I'll give you my two cents on your situation: If you are a scuba diver and comfortable diving ambient, go for a wet or semi-dry sub, not full on dry ambient. I say this because there are still an infinite number of learning opportunities with a wet sub, but you aren't dealing with the ballast weight needed to sink an entire air-filled hull. If you really want to go dry, go one atmosphere. If you are going to be leaving the states in 18-24 months, a wet sub (like a DPU / scooter or a bubble sub) seems like it's just the ticket... whatever you decide, good luck on your journey.

You are only ambient at a certain point between the bottom of your hull & the top. Everything below this point is under external pressure & everything above is under internal pressure. This can put a lot of internal force on the hatch. To visualize it, mentally flip your sub upside down and fill it with water to ambient point. The weight of water on your hatch will be equivalent to the internal air pressure on it when diving. There are modifications to the batteries that need doing if you want them in the hull, as they typically crush at about 15ft. You have 20 liters of air per person flowing in to the hull for life support plus the air for equalization, which is 4 x the volume of your sub at 100ft. So a lot of air needed. You need to watch that any electronics can handle the pressure you are diving to.

That would only limit me down to 130 foot allowed for recreational diving. -Ludwig -----Original Message----- From: James Frankland via Personal_Submersibles To: Personal Submersibles General Discussion Sent: Mon, Nov 21, 2016 8:44 am Subject: Re: [PSUBS-MAILIST] Looking at starting up a Submersible project I think emile has a small ish boat requiring refurbishment for sale?

You may find some information there. http://www.submarineboat.com/rov_sonar.htm I think Scott had some information on depth capability of one of his transducers, but not sure where in the World he is! I contacted a Navico tech rep asking about the Simrad forward scan depth rating, & there was no testing done on this. The good news is that most depth sounders can shoot through up to 1/2" of fibreglass. I am not sure whether it matters if it is epoxy / glass or polyester / glass. Would certainly be the latter as most boats are made of it. There is plenty of information on "Shoot through hull installation" on the net. You could possibly encapsulate the transducer in a fibreglass ball, making sure there is no more than 1/2" thickness in the transmitting area. As most boats have a hull thats angled to the surface of the water, I don't think it would matter having a rounded fibreglass form around the transducer. It is important that there are no air gaps or bubbles in the transmitting area. One idea I had was to make a miniature view port with a 1/2 inch thick fibreglass disk in it, & mount the transducer in the hull over that. This would mean no pressure & water proofing or through hulls. I think a 2" x 1/2" disc would do for about 4000ft.

If you got your calculations wrong & the disk burst it wouldn't be nice. You could epoxy the transducer inside this tube.

I bought my OTS set up for my sub and support boat about 3 or 4 years ago and about a year ago I called their tech support and asked them what the depth rating was for their transducers. I believe they said that they figured around 200' or so. Having a K-350, I figured that wouldn't work. They said that they just came out with a newer model that was good for a lot deeper (past the working depth of the K-350) so I bought it from a rep on Maui for $150 or so. OTS seems to be used by a lot of Psuber,s so has anyone out there that is using an older model had their sub transducer fail? if so you might check into the new model that can go deeper. Be interesting to hear from you all. Thanks and happy new year all.

This is similar to the CGA-850 SCUBA connection that many of you will be familiar with. While these yoke type connections are quick to connect and disconnect, IMO they are less than ideal for any sort of permanent installation. I long ago migrated away from CGA-850 in SCUBA because of the decreased entrapment potential and the greater security and pressure capability of the 300 bar DIN 477 connection. For submarines, consider the application. If you are buying industrial oxygen or breathing air supplied in cylinders, (or wish to retain the capability to use such cylinders) it makes sense to employ the CGA 540 (industrial oxygen) or CGA 346 connections (industrial breathing air) to mate to them as supplied. Certainly, you need to use standard valve connections on any cylinder which you intend to have refilled elsewhere. Conversely, for cylinders which are part of a permanent installation on a submarine, such as outboard oxygen, breathing mixtures or ballast air cylinders, I would question whether cylinder valves are necessary at all, provided you have a means of charging them. I might be inclined to replace a cylinder valve with an adapter to convert the NPS thread in the cylinder neck to e.g. 1/4 NPTF and plumb that into the hull or a general purpose regulator directly, provided of course that you employ the appropriate shutoff valves where necessary. If you only employ as many oddball fittings and connectors as it takes to convert to something standard and common, you reduce your inventory of spare parts and increase interchangeability. Note also that you can buy all manners of CGA gas connections to mate with standard cylinder valves which have NPT(M/F) on the other side. This allows you to manifold a bunch of cylinders together and plumb them to any general purpose regulator.

You only need a single core penetrator for this, but the coax shield ideally will be terminated to the penetrator in a way which completely surrounds the core without gaps (360? termination), as opposed to breaking out the shield and terminating it to a single point at the hull or penetrator. Passing the coax through a compression fitting accomplishes much the same thing, as the ground plane connection would simply be made at the antenna mount outside the hull, or you could not connect the shield to a ground plane and feed a dipole antenna instead. Video signals are a different story, as the video feed is a differential signal of typically much lower power than an antenna feed, and uses the coax for noise immunity. You wouldn't connect the shield of a video feed to the hull under any circumstances.

In-Reply-To: References: Message-ID: Hi Philippe, I used to own a K-250 and must admit the original MBT valve setup was not at all good. The valves were attached to the CT with screws that went right through the CT wall and were sealed with nothing but silicone, and as a result small drips were routine. I came up with my own setup using a valve stem extender that sealed with O rings, but later saw how Kittredge had done it in the K-350 valves and that was better still. On my new sub, I've gone with the K-350 method. The valves on the K-350 are Lance model 22-061, which are still made, and the attached file shows the through-hull. I used valves with the same exact body but increased the bore for faster diving.

I am using a Blueglobe gland fitting (BG 220 VA, rated @ 1,160 psig) on the outboard pressure side of the nipple and a Conax gland (PG5-500-A-N,rated @ 800 psig) for the gland fitting inboard. I was originally only going to have interior Conax gland and let the pipe free flood.? Then I decided I wanted to have redundancy and keep the pipe interior dry to help prevent corrosion (it is old school (not SS)). My question:? Is the air void that will exist between the 2 gland fittings a concern? Think empty pipe with both ends capped. I'm thinking not...

This is a 5K lumen array that I have enclosed in a small custom 2.25" OD 1-atm anodized aluminum housing with a SubConn MCBH-3-MP bulkhead penetrator. For altitude, I am using the Airmar DST800. This sensor communicates with Automation direct PLC via RS-232 using NMEA 0183 sentence structure. I am also using this sensor for ambient water temperature and speed. For Oxygen concentration I am using the Maxtec MAX-250 O2 sensor in a custom PCB. For CO2, I am using a CO2Meter.com K-30 sensor that gives a 0-5VDC analog output that is proportional to 0-10,000 ppm of CO2. * Cliff* On Tue, Jan 31, 2017 at 1:46 PM, Rick Patton via Personal_Submersibles < personal_submersibles at psubs.org> wrote: > Would love to hear from anyone who is presently using LED's for their > outside lighting.

I found he original K-350 plans to be pretty weak. Changes made were: 1. Removed aft external motor and prop and replaced with two fixed Minn Kota 101 thruster with kort nozzle like I have on the R300 2. Replaced vertical thrusters with two fixed Minn Kota 101 thrusters with kort nozzle 3. Propulsion and depth station keeping all fly by wire with joystick control 4. Move air tanks (two 100 SCF aluminum scuba tanks) outside hull old location of main propulsion motor 5. PLC for control of all systems (same as R300) 6. HMI and joystick on mobile to permit operation from prone, sitting or standing position. 7. Replaced life support with fully automated design used on R300 8. Moved electrical components into three electrical boxes on or near aft elliptical head 9. Added sensors for main and auxiliary battery voltage and current, ambient water pressure and temperature, cabin pressure, temperature, and humidly, compass heading, boat roll and pitch, boat altitude and speed. Life support system has sensors for CO2, O2 concentrations, O2 tank pressure, mass rate of O2 during O2 makeup. Pressure sensor for HP air bank and regulated air pressure. 10. Increased main battery capacity to 400 Ah which required increasing the battery pod diameter to 16? OD and 47? seam to seam 11. Replaced the main and auxiliary battery banks with 16 OPTIMA BATTERIES BLUE TOP DEEP CYCLE MARINE BATTERY GROUP D34M. 12 for main buss and 4 for auxiliary buss. 8 batteries per pod 12. Widened the spacing on battery pods to 38? 13. Added two additional viewports 14. Added external LED lights 15. Added compass/pitch/roll sensors off R300 16. Changed design of battery pods detachable heads to flange style 17. Redesigned the MBT and VBT controls. 18. Utilize Hugh Fulton pancake style pneumatically operated MBT vent valves 19. Modified MBTs by closing the bottoms 20. lengthened VBT to 18? seam to seam to increase the volume to 8.75 gals 21. Added compass/pitch/roll sensors off R300 22. Built out boat in Autodesk Inventor professional. 23. Drawing package updated, 51 assembly drawings and 160 part drawings 24. With mods, the current boat weight is 4,707 lbs, without pilot or passenger 25. With mods, the current boat submerged displacement is 4,866 lbs, 26. Buoyancy of boat with VBT and MBT fully blown is 5,849 lbf 27. Boat Reserve of buoyancy is 9.2% Cliff On Sun, Jan 29, 2017 at 12:18 PM, Philippe Robert via Personal_Submersibles wrote: > Nice for the list !
