Dive depth logger with arduino

[buton]

Thanks I might go kick starter once the design is more solid and when I had some quotes from pcb designers...

About the graph, I was discussing the same with a friend..maybe it is not needed, big numbers will help more..

The fun thing once I release the code you will be able to have the ui you want...

Diveduino is going tomorrow to the pool.....

Let's see how it performs...

So i took it to the pool yesterday

it was awesome, it worked, no water leaks

take a look at the youtube videos and don't forget to visit the webpag: DiveDuino Project - Home

Pretty cool vid... that slow screen refresh... is that how it appears or is it down to the camera?

 

[buton]

It is because of camera , it works great with the human eye... xd

Thanks

Here is an update:

so i manage go diving with the intention to test it to about 100 Feet... unfortunately it did not worky and it had a leak from the sensor to the housing, the oring worked good. the good think is that i did not have the electronics inside because i wanted to tested...

it was a nice trip though to the flower gardens in TX, is on the list for next year again...





so after that i began working on making a PCB, i made it in Eagle and it arrived yesterday, here is the board, it is the same size, why? because i dont want to put electronics on it via superficial mount, because the idea is that you can get the materials from any electronics store and put it together your self. i know it can be smaller but thats not the point. so i will keep working in assembly the pcb with the components and doing some design for the housing and sensor mounting. i might also start a kickstarter to fund the housing machining which is expensive....

Are you saying the sensor was not waterproof? It leaked through its own cable?

 

[buton]

sorry it is waterproof... it leaked because of the way i installed it.... to installed i did a hole and glue it with super glue but the 80 feet pressure won and leaked through the glue and silicon i use to secure it...

i guess i will have to find a water way to do it...

design link : https://docs.google.com/file/d/0B_zCxskEQaqjemtLZ3oxZW9Pdmc/preview

So I took some time to make a rough design, I don’t have enough mechanical experience so by reading I got to this design conclusion…
The sensor datasheet at page 20 http://www.meas-spec.com/downloads/MS5541-30C.pdf has information on how to mount it.

Based on the drawing I am able to get this oring
Cross Section of : 1.2mm
Inside diameter of oring: 5.8 mm
After some design on inventor I got the drawing on the link with some dimensions, the idea is to put the sensor and the oring press. Do you guys think it will work, obviously I will secure the sensor so the pressure does not push it, I just need to make sure water does not go in between the walls.

thanks

remember that you can encase the non-resistent-to-water in wax. It nicely displaces water away from electronics.
Then use the heat-shrink gun to melt it away from any section you need access to.

Another idea, is to use "cheap" graphene to conduct the signal from the sensor, instead of using small grade wires.

Even if you do use wires between the sensor and the electronics, you could probably get away with 32g with no rubber - just the copper.
Then laminate the copper strands with nail polish.

Smaller holes, easier to plug.
