I bought and installed one of these in a Ikelite D300 housing about a year ago - snug fit, bit it worked out great. No problems with shipping to Europe anyway ! I'm sure they do worldwide shipping.

I received an email back today

The guy said they can build it to suit any housing but you may have to email pics and dimensions

Think they are $70US plus shipping

The tampon idea seemed good though.

Not sure if it actually would work, but will try it.

If it save a $1000 camera, worth a go.

Hi,

nice product.

This circuit is well known & simple.

I made this 7 years ago. It cost about 3USD.

see my DIY leakdetector and this page (sorry in japanese).

you or your friend may produce it. :drink:

The Leak Detector at UWleakdetector.com is totally my own design and sadly doesn't cost US$3 for parts, plus you don't have to make it yourself.

The Leak Detector's that I manufacture are each hand made (by me!) and encased in resin for water proofing in the event of a flood. The battery is fully replaceable and seperate from the sensor circuit and sensor strip (both of these features are there so the unit keeps warning of a leak whilst it may be wet).

The sensor strip is designed to retain water by its perforated design, which pulls water into itself by 'capillary action'.

The electronics is designed with ultra low current draw in detect mode, so that when the unit is just detecting, but not finding moisture or water, the battery lasts for around one year without replacement.

The Leak Detector comes completely assembled and ready to fit into your housing, with full instructions and photos of how to fit it within 10 minutes without tools.

After a flood the unit can be cleaned and put back into use, in the event of a major flood, where any leak detector would not save the camera. The unit can be returned to me for quick replacement of battery holder and sensor strip for minimal cost and be back in service within a week (depending on where you are in the World).

I don't see any of these features in the US$3 model described above!

I send Leak Detectors anywhere in the World that Paypal works from. So far this has included USA, Australia, England, Sweden, Denmark, Germany, India, Sri Lanka, Egypt, Switzerland, South Africa, Israel, Indonesia, Malaysia, Japan, Taiwan, China, Thailand, Chile, Holland, France, Ireland, Norway, Poland, Canada, Hong Kong, Singapore, Spain, New Zealand & Croatia.

I have made Leak Detectors for a wide variety of housings, from the Olympus compact housings, through to everyday Ikelite, 10Bar & Fantasea DSLR housings (which are all stock items, ready for despatch within 24 hours) through to top of the range Hasselblad, Gates and ROV's for oil rig inspections, which are custom made and I may need a couple of photos of the housing/camera to ensure correct fitment.

I hope this clarifies what my product is and where it can be sent to, and why it doesn't cost US$3 ........... but guaranteed it will work when you may get an un-noticed leak.

Reefwalker, you know you are here in a DIY section.

Many people here are bored to pay a lot of money every time it is a question of materiel of dive or underwater photography.

As well made is your material, i think 70$ is too much for just a board, a transistor, a buzzer and a cell.

Many thank for guys like Hanachan and others to show us how to save money !

Hi Jcdignan

You may notice it wasn't me that started this thread!

I was simply clarifying that my Leak Detector doesn't consist of US$3 worth of material. It also isn't a board, a transistor, a buzzer and a cell. It's actually a whole lot more than this! Plus not everyone is handy with electronics and soldering etc. so these people can buy a pre-made item and fit it themselves.

I think its great that this DIY forum is here for people to save money by doing it themselves. I am a DIY guy myself. Which is how I came to manufacture the Leak Detector. I made one for a friend and then one for myself. Now I've made hundreds for other happy customers around the World who want a fit-yourself Leak Detector that costs a whole lot less than some of the housing manufacturers charge for the 'genuine article'.

1USD mini Leak Detector :D

 

Hi,

yesterday I found the mini flash light at the 100yen shop.

I thought it was suitable for the leak detector. So I purchased it

and made the leak detector.

 

I only disassembled it and soldered the sensor lead to it.

Its size is the same as the coin battery case.

post-23042-1238332050.jpg

 

I set the detector to the Canon G10 housing.

While it cost 1 USD (correctly saying 1.1 USD), it is smaller, brighter

and easier to set up than my 3 USD leak detector.

Details is here. (written in japanese & English)

 

Thank you.

Hi, good news!

Today I have found the same mini flashlight I used on DX.

This Item

Price is $2.8 (2-packs, Free shipping).

So I must change the title "1.4USD mini LeakDetector".

Let's try DIY!

Hi,

I have been asked why my cheap detector does not work in fresh water.

My answer is that fresh water has little ion ie high resistance. so the

electric current is very little(near 0) between the sensor electrode in fresh water.

As a result the detector failes to emit light.

 

I would like to show a solution that my detector can work in fresh water.

 

This light is very cheap but very intelligent. It works all or none mode.

When the electric current between the sensor electrodes exceeds some level,

it emitts.

The level to emit light is already fixed. We cannot change the level.

So it is necessary to increase the electric current between the sensor electrodes.

 

experiment:

I made the 2nd detector. It was very easy and I finished DIY about 10 minutes.

post-23042-1239203325.jpg

 

I prepared the salt and the paper.

post-23042-1239204014.jpg

 

I sprinkled the salt a bit over the sensor electordes on the paper

and covered it with adhesive tape.

post-23042-1239204615.jpg

 

The cheap detector was sucessfully emitted with the fresh water !

post-23042-1239205024.jpg

 

Of course, Under the Sea, NO salt is necessary.

 

Thank you.

Hi,

Yesterday I have dove at the Sado Island. At the ferryboat returning home when I opened

the tarvelling bag to take the waterproof case of G10, I found my cheap leak detector emitting light.

I was very surprised because there was no sign of water invasion in my diving course.

I opened the waterproof case and the right paper at the bottom of case seemed very little wet.

And a very small water drop (less than 1mm) attached at the bottom of G10.

post-23042-1241704323.jpg

I'm not sure when and where the water invaded. at water pool to remove the salt after diving?

I knew this cheap leak detector works well with very small amount of water invasion. :lol:

So I report.

Thank you.

Anymore idear or DIY love this stuff! ;)

 

Hi

While the leak detectors let you know that you have a leak they do little to stop it.

I found a product on the net that I have used and works very well.

They are called Leak Insure Absorbent Sachets http://www.leakinsure.co.uk . They absorb water very quickly and give you enough time to get to the surface.

I guess they would work very well with the detectors.

As long as they don't get wet they can be used over and over again, brilliant.

 

Has anyone got any alternatives?

 

Happy New Year

Hi Johnno thats a great idear if you had the room, for the mean time the leak detector will have to do , just need to know if someone has a better way of installing/making the little thing...

 

I have bought 2 of those lights just waiting to arrive.

Back in the old days (1970's) we used tampons in the bottom of our housings, but there was always lots of space under the camera mount. Modern housings are now much tighter, but it still works in an Ikelite :D.

 

Maybe one can consider to line the inside of a metal housing with that modern "super shammy" absorbent material...LOL. Drying out the inside of your housing with a hairdryer be a weird image though.

Nice DIY projects, and sachets surely help to some extent, but being sure there's no leakage before the dive is even better, at least for me. Can't be done for a couple of bucks, though...

Nice project, but sometimes sachets do not work. I can share the link www.aquar-system.com/ in case someone needs a kind of moisture meters and sensors. Their products proved to be reliable. I hope it will be useful!

Hi... sorry for brining back the dead thread.

 

Any idea where to get the DIY information?? I didn't manage to see any links posted by hanachan.

 

Please reposf the circuit and the moisture sensor of anyone has the images. thanks
