The difficulty is that the steel hull is deflecting the natural magnetic lines of the earth. Steel ships get over this to a certain extent by degaussing the ship. This is likely not an option. I read somewhere that WWII subs could not us a magnetic compass at all, but rather used a directional gyro. The cheaper aircraft direction gyro's are vacuum powered, but there are electrical powered dg's available. You would not need a flight certified one. EBay has a few but most don't say whether they are vacuum or electric. What do the others with the K-subs use? What does Phil install in the larger passenger (Aquarius) subs?

I don't get why it is not working, I can rotate the compass body and the ball inside stays fixed on the direction. When I travel on the bottom at 270 degrees, I deviate and correct and I expect to loosely track but maintain my direction. When I surface I am facing the opposite direction. Hmmm I wonder if the sub is rotating during the assent, that would make sense. I will have to watch the compass while I am surfacing, maybe the sub develops a spin.

G.L. calls it CDP (collapse diving pressure) TDP (test diving pressure) & NDP(nominal diving pressure).The test depth in relation to the operating depth differs depending on how deep you arebuilding for. If it is a shallow sub TDP is 1.7 x NDP. If deep, TDP is 1.2 x NDP.Also the relationship between CDP & NDP varies depending on your CDP.You do not operate at your test depth, just your nominal dive depth.G.L.

This means that in colder settings or lower humidity levels the crystals are inert, and also, this unit is not going to decrease the relative humidity below 50%. Factor that into your needs.

Be sure to use a non-soluble grease. And the good news is that SS bolts won't gall as a rule in high carbon steel. As proof, I offer the Perry subs, which have without a doubt done more dives in salt water than all other submersibles put together. And every one of them has hull matched steel inserts for viewport and penetration plates. We painted everything, sanded the mating surfaces smooth, and went on about our business. No problem. Even those shiny hatch mating surfaces you see in the pictures or Perry boats are A537 or A516Gr70 steel with monel cladding, rather than the softer and more damage prone stainless. Plus, stainless can have stress corrosion problems in oxygen starved atmospheres, and takes a lot of experience to use effectively. Vance -----Original Message----- From: Andr?

As an old shop rat, I will tell you that the biggest enemy of a good paint job is the sharp edge. Paint will necessarily thin there and on the rough spots and you will get rust pretty quickly. Take your time during fabrication. Break all the edges, including the bolt holes. Make sure there is no serious porosity on any weld surfaces. Then sandblast to white metal, clean, clean, clean the surface, and use a good multi-coat paint treatment. These days, probably not vinyl, like we used. But a good zinc undercoat, then high build epoxy topped with polyurethane will make a very tough and long lasting surface.

Or are you struggling to keep the cabin humidity down? You may have better luck condensing the moisture out with a cooling coil and draining it, rather than relying on heat to drive the %RH down, except in a truly sealed enclosure. For enclosures that you don't need to open frequently, dessicants may suffice. If you are only concerned about one or two specific components, you might look at aftermarket conformal coatings. These can raise moisture tolerance to 100% RH non-condensing for many components.

That said, 0.875" is reasonably thick, and if you model such a dished head, faced off normal to the centre of curvature, turned to eliminate the acute outside edge and grooved for an o-ring, then the minimum distance between the corner of the o-ring groove and the outer shell surface will give you a reasonable approximation of the shell thickness to use for calculation, but then means that the hatch will be significantly heavier than it needs to be. A deeper dish leads to less bending stress (and less extraneous material) but increases volume and decreases bearing area. There's probably an optimum tradeoff.

Be sure to use a non-soluble grease. And the good news is that SS bolts won't gall as a rule in high carbon steel. As proof, I offer the Perry subs, which have without a doubt done more dives in salt water than all other submersibles put together.

In the PLC, I have ladder logic that parses the string and converts these into real variables that are display on the HMI both graphically and as text. these sensors cost $325. There only a good idea if you are using a PLC that has a spare serial communication port.

You may have better luck condensing the moisture out with a cooling coil and draining it, rather than relying on heat to drive the %RH down, except in a truly sealed enclosure. For enclosures that you don't need to open frequently, dessicants may suffice. If you are only concerned about one or two specific components, you might look at aftermarket conformal coatings.

That said, 0.875" is reasonably thick, and if you model such a dished head, faced off normal to the centre of curvature, turned to eliminate the acute outside edge and grooved for an o-ring, then the minimum distance between the corner of the o-ring groove and the outer shell surface will give you a reasonable approximation of the shell thickness to use for calculation, but then means that the hatch will be significantly heavier than it needs to be.A deeper dish leads to less bending stress (and less extraneous material) but increases volume and decreases bearing area.? There's probably an optimum tradeoff.Sean On August 6, 2015 10:05:31 AM CDT, hank pronk via Personal_Submersibles wrote: Hi Sean,I was thinking about making a hatch from a single piece of dished material instead of the typical dome welded to a ring etc. ?

Be sure to use a non-soluble grease. And the good news is that SS bolts won't gall as a rule in high carbon steel. As proof, I offer the Perry subs, which have without a doubt done more dives in salt water than all other submersibles put together. And every one of them has hull matched steel inserts for viewport and penetration plates. We painted everything, sanded the mating surfaces smooth, and went on about our business. No problem.

Have you had any problems with rust in the threads when using steel and diving in saltwater? I would imagine filling the threads with grease, and inspecting them on a regular basis should be fine. Was hoping I could go with steel, as I can get them cut out from the same plate as the frontdome seat.

In my case, if my diving tanks were 500 liters in volume; this would mean I need roughly 2000 liters for surface requirements.? Correct. Corresponds e.g. to 10l x 200bar.?However for my NDD of 500 ft, to comply I will need to carry 10,000 liters. This seems ridiculous, as if I used a pump to empty my ballast tanks instead of compressed air,?I would have no ability to put air in to my tanks at NDD. This rule also penalizes me if I want to build bigger ballast tanks. Is there an exception to this 1.5 x at NDD rule, or have I misunderstood it? This Rule has its origin from submarines, which creates their own HP air reserves at the surface (naval submarines) and is not applicable for your submersible.? Instead, the HP air reserves shall be sufficient to compensate any possible loss of buoyancy at NDD. Decisive is normally the largest pressure tight volume except of the human pressure hull, e.g. battery pot, junction box, external buoyancy tank, etc..?

Normally I dry the interior after the dives but the dehumidifier brings it from 95% to 55 % in a day. During dives you can experiment with a layer of Silica in the scrubber . I spoke today with a boatshop owner about compasses. He told Raymarine has a new fluxgate sensor with build in gyro?s. This to compensate magnetic anomalies and heavy sea state.

The first is to keep the all the electronics heated pretty much all the time, even when I?m not using the sub and it is docked. The other is to install some kind of dehumidifier into the cabin that will run when the sub is not used. Kitty Litter is a good idea but I need something cleaner and easier to handle. Regarding the discussion about the compass issue, I?m using a fluxgate mounted about a meter over the hatch and an electric aviation heading gyro. The fluxgate is very sensitive to magnetic underwater rocks so it can not be trusted for longer navigations. Lasse 6 aug 2015 kl. 14:48 skrev Sean T. Stevenson via Personal_Submersibles >: Are all of your electronics confined to sealed enclosures? Or are you struggling to keep the cabin humidity down? You may have better luck condensing the moisture out with a cooling coil and draining it, rather than relying on heat to drive the %RH down, except in a truly sealed enclosure. For enclosures that you don't need to open frequently, dessicants may suffice. If you are only concerned about one or two specific components, you might look at aftermarket conformal coatings. These can raise moisture tolerance to 100% RH non-condensing for many components.

Any pointers what to search for and where? I?m not even sure how they look like. We have so far almost 250 dives with Malen this year, after the worst summer in decades with tons of rain in Sweden we?ll try to fight the moisture with some heating elements and a dehumidifier in the sub. The electronics does?t like to moisture for sure. All suggestions are super welcome.

I'm currently at about 90% completion although I've accepted the reality that I will likely always want to "tweak" it and so it makes sense to put a "flag in the ground" and call this v1.0 even though I may eventually change some of the colors and displays. It's a starting point that can develop as time and experience dictate. I have tried to keep within blue/green color schemes because I believe these will provide the best visibility in the blue light at depth. I still have to purchase the O2 and CO2 sensors, both of which will easily integrate with the microprocessors.

I like the overall layout and data seems to be presented in logical and straightforward manner. I think it would easy for someone other than yourself to get the state of the boat from this HMI. On your DIVE panel, I would add a couple of items. The first is the battery SOC and air SOF(state of Fill, 0-100%). These are key items for the home screen. Also, I would add a proximity switch on hatch so that the hatch state is shown. This can also be used to lockout diving the boat unless the hatch switch is closed. Also I would add Altitude. Airmar has a sensor called the DST800 that gives boat speed, depth (altitude) and water temperature. Signals comes in as a RS-232 ASCII string that you parse. On the NAV screen, I would include depth and altitude. On HIST screen, rather than looking at min and max on key variable's, I would recommend that up set up data logging and log all ship systems say every minute. Most PLCs and associated HMIs have data logging capabilities. This allows you to download all sensor measurements and switch states as a function of time. This is useful to analyze how the boat performed after the dive and also serves a Black Box for the sub. I did not see any alarm database. Need to be able to see and hear and audible alarms an such items as low air pressure, O2 and CO2 out of range ...

Alarms are located on the left side under the yellow/black warning graphic. Each one functions as both an alert and alarm. For example, a yellow alert lights up "DEPTH" at 500 feet to warn of approaching maximum depth. At 600 feet it turns into a red alarm. These alerts and alarms can only be disengaged by retreating back to a non-alarm operating environment (ie.. decreasing depth to less than 500 feet). Audio alerts will accompany the visual ones. Depth is available on all displays in the lower left corner. Data logging is included and can be written to a USB drive and 'replayed' on any other computer that has the same software on it or even imported into something like a spreadsheet. However, if I end up with a tablet I will likely log there directly. Battery information will be added when I get those sensors. This design lends itself well to semi-automated control, for example typing in a target depth of 100 feet and then letting the computer operate the motors and monitor vertical rate of descent/ascent, slow down when approaching the target depth, and then shutting off the motors at/near target depth. A more distant and advanced project would be, I don't know, maybe inertial navigation using an IMU.

Good to get interpretation from GL. It would be good to get Carsten?s clarification. Hugh From: Personal_Submersibles [mailto:personal_submersibles-bounces at psubs.org] On Behalf Of Alan James via Personal_Submersibles Sent: Sunday, 9 August 2015 4:06 p.m. To: Personal Submersibles General Discussion Subject: Re: [PSUBS-MAILIST] Fw: 12 Volt Reversing Continuous Duty Silver Contact Solenoid Relay for Winch Motor | eBay Hugh, below is my question & answer in blue from G.L.. It is still a little ambiguous; it seems you need enough air to counter the negative buoyancy effect of one of your battery pods or largest other non pressure hull air spaces being breached at your maximum operating depth. I assume this volume is additional to the volume of air needed to blow your ballasts 4 x on the surface, as, if you were on your 4th dive & a pod filled with water you would need to counter this negative buoyancy & blow your ballasts at the surface. Alan In section 9, Piping Systems, Pumps & Compressors it states in 3.1 that there must be enough air to blow the diving tanks 4 x at the surface & 1.5 x at NDD. In my case, if my diving tanks were 500 liters in volume; this would mean I need roughly 2000 liters for surface requirements. Correct. Corresponds e.g. to 10l x 200bar. However for my NDD of 500 ft, to comply I will need to carry 10,000 liters. This seems ridiculous, as if I used a pump to empty my ballast tanks instead of compressed air, I would have no ability to put air in to my tanks at NDD. This rule also penalizes me if I want to build bigger ballast tanks. Is there an exception to this 1.5 x at NDD rule, or have I misunderstood it? This Rule has its origin from submarines, which creates their own HP air reserves at the surface (naval submarines) and is not applicable for your submersible. Instead, the HP air reserves shall be sufficient to compensate any possible loss of buoyancy at NDD. Decisive is normally the largest pressure tight volume except of the human pressure hull, e.g. battery pot, junction box, external buoyancy tank, etc.. _____ From: Hugh Fulton via Personal_Submersibles To: 'Personal Submersibles General Discussion' Sent: Sunday, August 9, 2015 3:14 PM Subject: Re: [PSUBS-MAILIST] Fw: 12 Volt Reversing Continuous Duty Silver Contact Solenoid Relay for Winch Motor | eBay Alan, Blowing of tanks.

TABLE 1 Color Codes for Piping and Gas Storage Bottles Name Designation Color Oxygen O2 Dark Green Nitrogen N Light Gray Air (Low Pressure) ALP Black Air (High Pressure) AHP Black Helium He Buff Helium-Oxygen Mix He-O2 Buff and Dark Green Exhaust E Silver. Sorry the copy & paste didn't turn out well, the above was in a table form. It also says that other color codes can be used. It doesn't talk about the valves themselves, but these would be required to be labeled. I am sure DNVGL would have similar in their piping section.

Sean On August 10, 2015 1:39:02 PM MDT, Jon Wallace via Personal_Submersibles > wrote: HI Cliff, thanks for the feedback. Alarms are located on the left side under the yellow/black warning graphic. Each one functions as both an alert and alarm. For example, a yellow alert lights up "DEPTH" at 500 feet to warn of approaching maximum depth. At 600 feet it turns into a red alarm. These alerts and alarms can only be disengaged by retreating back to a non-alarm operating environment (ie.. decreasing depth to less than 500 feet). Audio alerts will accompany the visual ones. Depth is available on all displays in the lower left corner. Data logging is included and can be written to a USB drive and 'replayed' on any other computer that has the same software on it or even imported into something like a spreadsheet. However, if I end up with a tablet I will likely log there directly. Battery information will be added when I get those sensors. This design lends itself well to semi-automated control, for example typing in a target depth of 100 feet and then letting the computer operate the motors and monitor vertical rate of descent/ascent, slow down when approaching the target depth, and then shutting off the motors at/near target depth. A more distant and advanced project would be, I don't know, maybe inertial navigation using an IMU.

I like the overall layout and data seems to be presented in logical and straightforward manner. I think it would easy for someone other than yourself to get the state of the boat from this HMI. On your DIVE panel, I would add a couple of items. ! The first is the battery SOC and air SOF(state of Fill, 0-100%). These are key items for the home screen. Also, I would add a proximity switch on hatch so that the hatch state is shown. This can also be used to lockout diving the boat unless the hatch switch is closed. Also I would add Altitude. Airmar has a sensor called the DST800 that gives boat speed, depth (altitude) and water temperature. Signals comes in as a RS-232 ASCII string that you parse. On the NAV screen, I would include depth and altitude. On HIST screen, rather than looking at min and max on key variable's, I would recommend that up set up data logging and log all ship systems say every minute. Most PLCs and associated HMIs have data logging capabilities. This allows you to download all sensor measurements and switch states as a function of time. This is useful to analyze how the boat performed after the dive and also serves a Black Box for the sub. I did not see any alarm database. Need to be able to see and hear and audible alarms an such items as low air pressure, O2 and CO2 out of range ...

This could be a small 5" 800x600 monitor incorporated into a radio-control transmitter type handheld unit or it could be a 24 inch 1920x1080 computer monitor. None of these would be moisture rated and would require adequate protection but I don't see this as an exceptionally difficult task. At a cost of between $75-$100 I would keep a couple of spares on-board in case water infiltration caused component failure. Tablets are much more expensive, but waterproof cases can be obtained for tablets pretty cheaply, $50-$100. The primary attraction for using a tablet is one of convenience in that it is self-contained regarding operating system, storage, HD display, and even battery backup if the main batteries fail. Additionally, you've got a fully functional tablet that is easy to carry in/out of the submarine. Not diving today?...well you can still use the tablet for other things.

Plus, you need to clean everything so the fact its removable facilitates cleaning. Having said that, on Snoopy it all goes through SS -- but there's a regulator directly on the tank so I'm only dealing with low pressure O2. It is the high pressure lines that are most critical.

They are typically for tech divers, but would be useful for psubbers too... http://stores.ebay.com.au/tfmengineeringaustralia?_trksid=p2047675.l2563 http://www.tfmengineering.com.au/ Teflon tape is fine, but highly recommend dedicated oxygen service Teflon tape (probably just the same stuff but clean/degreased) - Unasco green "oxygen" tape is what we use exclusively at work, it's expensive like Hank found, but lovely to work with. 4-5 tight wraps is good, but try to make sure you don't have any hanging off the bottom of the thread that may get in the flow path. I also have some cheaper stuff that does the job. Regular pipe goop is a very bad idea - you can get specialised oxygen stuff (Ie. LOX8 paste) but it's very expensive. Stainless will burn in oxygen, but it's pretty hard to get started (think of a wet hardwood log) and is pretty commonly used for both fittings and tubing in industry for oxygen service, even up to 250+bar (~4000PSI). Brass/bronze is better though if practical (and the fittings are usually cheaper) as it won't ignite at all. Copper tubing with brass compression fittings is nice if you can find copper tube and brass fittings rated for the pressure (be careful), but if you use SS tubing you have to use SS compression fittings to get them to bite - don't use SS tube with brass compression fittings. Key thing is to keep the velocity down and try to avoid impingement points - ie. sharp corners (ie. elbows) or dead ends (ie. gauges, closed valves). This is commonly an issue on initial pressurisation. Also to properly oxygen clean the system and scrupulously keep it that way. And to put it in perpective - even the most oxygen-compatible elastomers (Viton, sort of EPDM) and plastics (PTCFE/PTFE) are waaaay easier to burn than SS, and you will probably find these in the most critical/high velocity places like valve and regulator seats as a standard thing.

Shameless plug:?Through my?side business TFM Engineering (still a work in progress), I have copies of the oxy hackers guide for sale on ebay down under if anyone needs one, also a bunch of oxygen valves, hoses, cylinder fittings, SCUBA fittings?and other things.??They are typically for tech divers, but would be useful for psubbers too...http://stores.ebay.com.au/tfmengineeringaustralia?_trksid=p2047675.l2563http://www.tfmengineering.com.au/ Teflon tape is fine, but highly recommend dedicated oxygen service Teflon tape (probably just the same stuff but clean/degreased) -?Unasco green "oxygen" tape is what we use exclusively at work, it's expensive like Hank found, but lovely to work with.? 4-5 tight wraps is good, but try to make sure you don't have any hanging off the bottom of the thread that may get in the flow path.? I also have some cheaper stuff that does the job.? Regular pipe goop is a very bad idea - you can get specialised oxygen stuff (Ie. LOX8 paste) but it's?very expensive. Stainless will burn in oxygen, but it's pretty hard to get started (think of a wet hardwood log) and?is pretty commonly used for both fittings and tubing?in industry for oxygen service, even up to 250+bar (~4000PSI).? Brass/bronze is better though if practical (and the fittings are usually cheaper) as it won't ignite at all.? Copper tubing with brass compression fittings is nice if you can find copper tube and brass fittings?rated for the pressure (be careful), but if you use SS tubing you have to use SS compression fittings to get them to bite - don't use SS tube with brass compression fittings. Key thing is to keep the velocity down and try to?avoid impingement points - ie. sharp corners (ie. elbows) or?dead ends (ie. gauges, closed valves).? This is commonly an issue on initial pressurisation.?Also to properly oxygen clean the system and scrupulously keep it that way. And to put it in perpective -?even the most oxygen-compatible?elastomers (Viton, sort of EPDM) and plastics (PTCFE/PTFE) are waaaay easier?to burn than SS, and you will probably find?these in the most critical/high?velocity?places like valve and regulator?seats as a standard thing.?

Plus, you need to clean everything so the fact its removable facilitates cleaning. Having said that, on Snoopy it all goes through SS -- but there's a regulator directly on the tank so I'm only dealing with low pressure O2. It is the high pressure lines that are most critical.

When they leak (not if, but when) the water will run to one end of the sub or the other. A small sub here locally had that issue and ended up standing on its tail with no way for the pilot and passenger to flood down and get out. Happily, they were in shallow waters on a test dive, and the Coast Guard was able to fish them out. Historically, we didn't use bladders. PC-8 originally had one (that leaked!) so it was replaced with a flat top fiberglass tank curved to match the hull radius which fit under the deck. That tank held, and one supposes still holds, a couple of hundred pounds of seawater. With internal ribs, the single tank was replaced by individual, interconnected tanks (usually 4 of either fiberglass or SS, depending on the customer) that would sit down between the ribs and could be pumped in and out, as well as fore and aft. Great for commercial payload changes, but probably overkill for us little sub guys. Keep in mind. Two dozen of the most successful submersibles in history. And no VBT bladders. Ever. Something to think about.

Cut at least two coupons ( statistical average) for each weld position that you find yourself working in , ie flat , vertical , horizontal or overhead. The coupon in your picture is too wide to be adequately stressed enough to show any deficiencies . Also a "face" bend like that just isn't a rigorous enough test. That position is usually used for welding school newbies to "build" confidence .

Several people tried to ride it underwater while wearing conventional single-tank SCUBA gear with not a huge amount of success. I think it remains an underwater bike... Some key lessons learned that may be useful: - Without pedals attached to your feet, it was impossible to put enough weight on the pedal to move the thing forward - In even the slightest current or surge it fell over! (almost inevitable in shallow water in anything other than a very well sheltered place) The second one probably won't apply so much with your ballast and floatation tanks - but if you're trying to keep the wheels in contact with the seabed the whole thing will tilt from side to side.

Ive had similar experience trying to ride a bmx underwater once. However, in this case I think they just want to simulate a sub going up and down. Im not sure what the point of the bike is. Its not intended to move I don't think. The thing im thinking is that I could do away with the bike and maybe put a seat with a bubble up top and make it a bit more of an ambient, rather than a wet sub.

Add a small VBT, either internally or externally in a hard tank (you could blow this with HP air instead of pumping, but would need to valve it to isolate it from ambient pressure changes), to compensate for minor crew weight differences, and compensate for the major ones by adding or removing lead. You want to avoid a situation where a depth change creates a buoyancy change, except in the sole case where you have blown your tanks to ascend.

I am a bit concerned as I have read of subs getting temporarily stuck in the mud on the bottom. Haven't heard of any getting permanently stuck but there is always a first time. Have also heard of them picking up a lot of weight in the form of mud. Would be good if there was a quick easy lead transference system. Maybe Alec's buoy system is the simplest & easiest to use! Just clip on a number of buoys that account for the weight of the passenger. With lead it has to be placed low, so when doing dive ops it would need to go in through the hatch to the hull bottom. Alec's system has the buoys in a tube, but I am thinking that they could all have short cords on them, with clips to attach to various points on the top of the sub.

I've actually changed my MO over time. Initially I liked diving heavy. It was an effortless way to descend, and I would get neutral with the VBT once at depth. If slightly heavy then you can use the thrusters to hover, but they will be pointing down and that ruins the visibility. I used to surface on air. These days, I just weigh myself and passenger and I have a little table on my clipboard telling me how many buoys to load. Once you've figured the payload of the sub once, the method nails the buoyancy every time, and I mean to within 5 lbs or so. I both dive and surface on thrusters, although it is true I have to blow a little bubble in the MBTs on deep dives due to hull compression. I find thruster dives make for better control and use way less air. Thruster movement has less "momentum" than buoyancy driven motion, meaning that you can shut off the propulsive power instantly whereas, if your propulsion is coming from a tankload of air, it takes longer to vent or flood the tanks. Its also handy that the sub just hovers if you stop paying attention for any reason.

No way around this problem but to use a higher quality pressure transducer, and data acquisition hardware with sufficient bit resolution to capture the available resolution of the instrument. You can filter out noise, but that doesn't help with hysteresis, repeatability or absolute accuracy. I often use Honeywell STJE series pressure transducers in high accuracy applications, but they're pricy.

Provided you calibrate your transducer against a calibration standard with some regularity, often any given transducer will outperform its rated specs, which are supposed to be worst-case scenarios. In this particular application, since we are really after altitude control and not the specific absolute depth, +/- 6 fsw on absolute accuracy may be fine if it is sufficiently stable at steady state.

I had given an answer/procedure I thought I remembered from a book I read "The 12 Volt Bible for Boats". I just wanted to share it again as I wasn't sure I got it exactly correct. It is a simple process and of course you want to avoid accidentally shorting your system during testing. Using a 12 volt test lamp or a current meter - Remove the battery's positive terminal connector - Make sure all circuit switches are off (open), fuses are in place and master battery switch is on (as applicable). In this state there should be no current flow - Place the test lamp or meter in series between the battery's positive terminal and the connector that was removed (pos. to pos. & neg. to neg.) - If the light is lit or the meter reads a current value you have an issue (the brighter the light or the higher the current value the larger the current flow) I believe this test should be done when the sub is in the water to ensure any stray paths that might be due to exterior wiring being wet are captured. Anyone done this test or have other ideas? Steve -------------- next part -------------- An HTML attachment was scrubbed...

As I understand it, the LED drivers have a switching frequency so are turning on & off the power to the LED. When electricity runs through wire it creates a magnetic field & when the power is switched off, the magnetic field collapses & causes a surge of electricity. Like a coil in a car creating a spark across a spark plug. The LED doesn't like this. The longer the run of wire, the more inductance is created. The capacitor is a buffer for this & there are big ones on high power LED drivers. They are there to combat the inductance from the battery to the driver, but by lengthening the wiring from driver to LED you create the problem out the other side. Perhaps a capacitor could be placed in the light fitting, & the driver in the pressure hull. This would reduce the footprint inside the fitting & stop the rest of the electronics from being exposed to any heat build up. you would still have the problem of pressure on the capacitor if you compensated though. Have seen pressure resistant capacitors, but don't know enough about them. I will go & see a friend who is an expert on this.

The epoxy would stop the heat escaping, but I guess only marginally if the coating was thin. I am not sure that normal epoxy would cope with the heat. It may have merit. I did something like that with a flounder light, but water got in & killed most of the LEDs. Have had difficulty a couple of times sealing the individual copper wires at the point where they go in to their insulation.

Then maybe the back of the array could be in a small amount of mineral oil, or cover the back with epoxy as well ? I have some LED's on my kayak that I have covered with a coat of clear epoxy and I've been using them for a few years now, of course they don't get submerged. > > > > Brian > > --- personal_submersibles at psubs.org wrote: > > From: Alan James via Personal_Submersibles > To: Personal Submersibles General Discussion > Subject: Re: [PSUBS-MAILIST] Light lense > Date: Mon, 31 Aug 2015 22:51:44 +0000 (UTC) > > Hank, > you have got me thinking.
