Next time, use silicon sealant between the lens the same way you did but don't torque the screws down all the way. Let the silicon set and essentially make a perfect seal, then torque the screws down so that you maintain pressure on the newly formed rubber seal. This has helped me in the past.
Love the videos!
Edit: Okay don't use silicon! Use whatever sealant is best but the technique is valid. Basically making your own custom seal and then tighten down onto it.
Don't use silicone. Use 3M 4200 marine sealant.
@@trey1531 And give it a little time to skin over before torquing the screws.
better tip: don't use sikicone to water seal. Silicone is crap compared to orings. Your shape is not round? Use oring string from diy oring kits
@@ihavecojones actually you're right, one big oring around the outside in a rounded groove and she's good to go. Multiple large diameters in motors are oringed.
This is how you reseal oil pans on cars that don't use gaskets, let it dry and then tighten more
I honestly keep coming back because of how I know I'm not getting a one attempt and over video. We know you are going to normally design something, test it, improve it, and when even my doubts are like "Nah he's not gonna get this" somehow you freaking pull it off. If you don't, we still learn. It's an amazing formula that I fall for every time and I love it :D
Thumbnail is good.

Cool little small projects we really need more of these
You could lower the exposure on the Timelapse so it’s not clipping. Take a separate photo for the background as it’s static. This could make for a more even end result. Or use bracketing for multiple exposures and combine them as hdr.
That was way COOL! I like both pics, the uneven and photoshopped of the underside of the montlake bridge. The "little fish that found a friend" likely was blinded by all the light and just trying to snuggle up next to something bigger. LOL
love that right after the shot of you wondering at the amount of particulates in the air, you have a glimpse of port industry smokestacks in the next shot
Instead of compositing, you should try a very long exposure shot on a DSLR with low ISO and low aperture (and ND filters if needed to lower the amount of light hitting the sensor even more), and then try to drive at a constant pace. It could make for very cool effects... but the sea weed would probably appear super "soft" and blurry secause of ripples on the water, underwater currents etc.
Or bulb mode.
the problem with this approach would be the super bright spot making huge trails covering up everything
You could fill the lamp body with mineraloil. this solves the buoyancy issue aswell as the water creep. the water wants to get inside because of the pressure delta. having the oil in it would keep the pressure the same and it also helps to keep the leds and inductor cool
I thought similar . You think the mineral oil would scatter the light any differently?
@Chris Barter it would have some effect. But it might be negligible because of the output power of the light. Als if the oil is directly touching the led. The light will refact less compared to air. I have seen it somewhere it has to do with the difference in refraction between 2 mediums
Mineral clear oil can be used
if you can't keep air out; does this run the risk of allowing a bubble to eventually form inside?
This would be very useful for underwater search and rescue applications.
A fleet of autonomous lighting submarines would be crazy cool around a boat. Especially if you can tune the lighting color
8:19 bro I swear that looks so familiar
“optimal underwater lighting, for maximum party vibes“ what a banger of a statement
The moment I saw how you made the cable pass trough and port window seal, I knew it will leak.
Epoxy shrinks when it cures ! Creating a slight gap all round, that is not necessarily visible by eye.
One way of overcoming this, is by casting the wire into epoxy, then coat it in silicone.
If you make something like a cone that fits into a cable gland that can be tightened, you have less
chance of leakage.
Front port is better done with a routed groove and O-ring, or cured silicone bead in groove, before
tensioning the port window.
Bear in mind, the meat and air inside will expand a lot due to heat, than shrink rapidly when cooling down,
essentially drawing water in.....
This is so cool please continue with this would love to see a whole lake long exposure shot
You can underexpose the camera (with apeture and iso) and just leave it with a 60+ second exposute while you drive around. No photoshop required, just get the right settings on the camera :)
Maybe with a boat that has an adjustable stick in the water, and exposing light on boths sides and some autopilot you could get some great results!
But damn, great video as usual, love that RC DIY stuff!!
Best option is make a water block, brass wire maybe 40mm long with centre 30mm portion set in epoxy, solder wires to both ends. We use it to 3000m
Put some of the anti moisture bags in your lights or make the air very dry where you seal it.
Most ACs have a dehumidification mode in them.
Try removing the reflector to make the beam broader
Hardware heavy solutions to problems that don't really exist.
*Awesome.*
Hi Daniel, nice video as always. It changes from regular videos! Have a nice day
Awesome project! Have you thought about milling or etching out a groove in the polycarbonate to fit an o-ring?
I haven't made any waterproof containers but I think they usually have a seal inside the screw parameter and compress it to make sure it seals well.
Great photo result of the bridge.
finally you answered my thoughts
I believe the moisture detected was ambient moister already present in the enclosure that reacted to the heat generated in the sealed chamber. As in moisture in the air since the air was not evacuated before final assembly. Created an atmosphere
I already see a lot of helpful comments but i'm not sure if anyone has mentioned yet that he should point the light at the bottom to help ease the gradient and over exposure up close to the lens. This relies on the light bouncing off the bottom but from the shots where he had it suspended mid water column and pointed down, the lighting and ability to see the bottom of the lake/river looked better!
In photoshop use the blend if layer settings to smoothly knock out the highlights. Do it for one layer then copy and paste layer styled to the other layers. Select all the layers and turn them into a smart object. Then go to main menu layers>smart object >stack mode. And try mean medium or maximum.
Was just gonna suggest this
1:12 nice😂
Neat project, and although the end result wasn't to your expectation it still looked wonderfully surreal. Hope we get to see some treasure hunting missions with the FIFISH grabber arm soon!
Idea: Add an inner tube valve to your box to be able to create a little overpressure inside with a bicycle pump... This way you can see if it has bubbles and therefore leaks...
The inner tube valve is calling a Schrader valve.
Good stuff! Any chance you'll design a lowe r power Lumiboost driver, in the 20-50W range? That would be perfect for my photography needs
The uneven is sweet. Looks like glowing algae in the water
You are best to use "sensor safe" RT silicone as it doesn't off gas when curing which causes clouding on transparent surfaces.
You might try positioning the light facing down on the sub to diffuse the light more and block the highlights
I remembered an idea I had a while back, & had to mention it. Have you ever considered building a scale model of Alexander Graham Bell's circa 1911 hydrofoil boat? I would absolutely LOVE to see how it would perform overall, especially at high-speeds (relatively), at scale.
Awesome idea 💯 I could think of a million things to do with it 💯👏👏😎
Hope you enjoyed Newport and Huntington!
Autonomous gigging boat would be sweet. 😂
would love to see u make an autonomous rc submarine that uses an ins to navigate the lake. can dead reckoning work well enough to navigate an rc submarine?
Daniel is gonna make all the conspiracies come out xD
"DID ANYONE SEE THAT UFO IN THE WATER?!?!"
The unhinged part is where people jump into the ocean at night with seaweed 👀🤯 your work is amazing mate!
Epic video! Convert to the way of the o-ring, brother :). Look up tarkka o-ring sizing video if unfamiliar. That face seal can be o-ringed and also the screws that go through the housing can have boss oring seals like in hydraulics. Sick photos
Next time use solidcore wires without insulation to pass the power from the outside to the inside. multi stand wires will always have some smal airways in it just like you mentioned. a solid wire might not be flexable but when your outside you can go back to muli
6:35 Would be a bit difficult to spot gold against that background.
I thought initially you were making a high depth light. I thought filling with fluid and a moveable piston seal might be interesting, if the components can take the pressure.
What kind of cost are we looking at from PCBWay? I didn't know they offer so much beyond PC boards.
Man I love Collin 😂
Nice👌 put a metal detector on it to find stuff!
Or make it even autonomous and mark the Points with GPS to dive down afterwards digging out what the robot has found. Would also work on land:)
This was fun. Thank you.
What was the total machining costs for the housing? Thank you for sharing this!
go deeper into the dumpster! add a shroud with a diffuser so you can't see the light directly, and maybe use a miniblind style lifting mechanism to control the angle of the light in 2 axis, 4 crawler winch wheels for servos could do that job well even if a bit slowly
Awesome ! Can you recommend a camera that can be mounted on a pole that would transmit live feed to a phone at say 6-8 feet underwater?
I saw in someone else's video what that secret board is from PCBway. I won't spoil the fun.
Lmao wish I walked by here when you were filming this I walk by that bride at 12:07 all the time
Fish: OH ITS SOO BRIGHT! Wait wait, it’s dark now…. Hold on… it’s daytime!?!? AHHHHHHHHH
I think diffusers would spread the light better than a super bright beam
You were in my neighborhood and I missed you! 😭
Somehow get a camera mounted to the raft that follows the light, might be able to get more even images
I would like to see more Rc plane videos
Needs O-ring, all dive lights have one. Can get device that can pressurize vessel too.
1:12 yup that's corn
Looks like it's on the cob too.
this would be perfect mounted on my boat. I use green light to attract bait.
Next time just make the case out of two halves, add a seal in between, and you can screw the power to the casing. :)
I was just watching another channel (Tech Ingredients) that mentioned that silicon can be permeable to water. That was a surprise to me! How bout yourself if true? Therefore the epoxy may not be the problem to sealing the electronics in the box from water. It may be the silicon seal you are using. Another possibility is a high moisture content of the air, or humidity when you sealed the box, and then the much cooler water temperature caused the humidity in the air in the box to condense down, or precipitate into actual water within the confines of the box. Possible remedy are silica gel beads (called a desiccant) used to keep things dry in high humidity conditions. Its interesting how Wikipedia described silica gels: "Canisters are commonly filled with silica gel and other molecular sieves used as desiccant in drug containers to keep contents dry". "Molecular sieves" Water easily flows through a sieve, but who knows!
A heads up I have used that speaker wire as it was all I had to get my solar in my caravan working and in just 2 weeks I stragley had only a fraction of the power coming through and it turned out to be the speaker wire reacted with the normal power cable it was all green and corroded and the same happened to a friend a year later. Luckily for him I had the issue prior as he had no clue and was out of ideas.
Just a heads up to anyone using speaker cable especially if ur using it and not getting the power through. Hope this helps someone out there one day.
A connector block would prob work as long as the wires don't touch and u only have speaker wire to work with. Xx
You should aim the light down this would/should only keep the diffusion in the water visible -- should make things better for photography...
hello, my team has been trying to seal a robot and we went through alot of different sealants. Silicone is very stiff and it doesnt' conform very well when the body moves/bends. We found that butyl tape is very good at sealing. It doesn't harden up, so it's a little messy, but it easily conforms to the seal and literally no drops will come through.
It probably failed the first time because of thermal expansion from the air in the casing. warming up air creates pressure. Make sure you have some kind of membrane to relieve the pressure. None the less cool project!
Very likely. It would also probably have been better to have the cover compress an o-ring in a v-shaped groove in the case rather than rely on silicone (under the holes for the screws instead of inside, even) for the seal.
Yeah man do what we say afterwards while sitting on the couch.
You have a fun circle of friends.
What about those silicon moisture absorbtion beads to keep the condensation out of the case?
Very enjoyable video, more music interludes please.
Nice project, but can I offer you an advice from some one who designs underwater "thingy-ma-bobs" for a marine research department on a top 50 polytechnic university?
What you have designed there, Id' be very surprised if is didn't leak when it goes to a few meters.
You should have designed a n o-rings groove in to it and added a o-ring, you should also have added an cheap penetrator from bluerobotics for you wires connections. No need to use Subconn connectors that cost an arm and a leg.
Also, I'm curious, what did the enclosure and the poly front cost if you had to buy it yourself? been considering trying them out for future work projects.
An alternative to trying to seal around your wire directly is to install a barb fitting in your housing and run your wire through the middle of that, then encase the wire in a long piece of vinyl tubing. It's bulkier, but since stuff like hose fittings are intended to make good seals, it's much easier to avoid seepage this way.
Also, if the hose squishing with depth is a problem, you can fill the whole thing with mineral oil.
As others have mentioned, the reflector is actually hurting your purposes here. A better design would use two COBs with no reflectors mounted back-to-back on a single heatsink "fin" with the housing as thin as possible to get as even a sphere of light as you can.
Pro Tip.. Use Polyurethane Glue For The Ultimate Waterproof Seal 👍
.
The type of glue used to seal RVs / Motorhomes
.
.
In england its approx £10 per tube
.
And you will need a caulking gun
.
But its WAAAY better than epoxy resin or silicone
.
.
.
The downside is its SO DAMN STRONG .. it makes it VERY hard to dismantle
.
.
This glue is also used to glue race cars together and its that strong the metal rips round the glue joint in a crash !
Any chance a laser line would do better? You could cover more distance just less area, but be able to combine the pictures easier by only having to spin the vehicle and having one point of blow out.
You should of used a rubber seal channel in the aluminum block. Would have a longer life and can go deeper.
I hope you snagged those knipex pliers homie
Maybe get an nd1000 filter for your sony lense and get a much longer exposure time instead of a lot of frames you could than get away with fewer more evenly lit ones
wait wouldnt something like a wall of light at the entrance be a good detection barier for enemy submarines for naval bases ??
Sebastian is great. He’s been around since the beginning, correct?
Why no oring grove on the front of the aluminum block to seal when the cover is bolted on?
more interested in how you did the manual photoshp and design gears
Do you still have the supercub? Like to see you fly it, for old times sake
Add water absorbing pellets to get any water that leaks inside
Underwater lights are commonly used to attract fish 😁
Great video!
Tip about water sealing stuff.
Silicone is really bad at sealing flat surfaces, next time use oring-string and a channel.
15:01 they found a little spoon
Use the rov to lay a grid of leds.
sharks hunt at night, reef, bull, tiger, hammerheads all in there with you :)
I love all the sub stuff
I feel like you need a softer light source. Youre basically using a spot light and you need a diffusive head on the light.
I know it's salt water, which isn't ideal, but if you dump it off the pier into the sound, you might be able to attract squids which would be kind of cool on film.
How much did this cost to make?
I think you need to use lasers to achieve wht you wanted to originally. And you need to use UV lasers, since the light will travel further. Then you could 'sweep across the water area while doing a time lapse, the camera would need to use a UV filter also. Maybe a visible light laser would work too but I think UV would be cooler
Maybe having a lens like on 360 cameras would diffuse the light.
"great for check a shark" LOL
have you seen Mark Rober's recent Zipline video? do you think you could attempt to re-create the asymmetrical propellers shown in the video?
