@Mohamed.r Even if it where you live is prone to things corroding (rust as you call it), the camera case would do little to protect it.... It would have to be air tight for it to prevent any kind of corrosion...

I assure you , the ezb can rust. Lol , I have had it happen. However I also did a video of how to clean the board after getting that one particularly nasty. As far as the Case goes and "air tight" a little silicon can remedy that. I'm just chiming in because the concept of corrosion is possible and I would hate for everyone to think this guy is crazy.

@mohammad, who did you ask to print by the way? I had someone else make a comment they tried to message me for 3d print but then I didn't get anything.

If I recall correctly the corrosion was from the pin headers and had spread over the fibre glass pcb - fibre glass does not rust, what you were seeing there was the effects of a lot of condensation or water.

In the open the EZ-B will not rust from normal levels of humidity and condensation. In damp conditions there may be some level of corrosion on the components if they are untreated.

Unless the EZ-B is planned to be submerged in water or used close to water or areas of high condensation it will not be a problem. Just sealing the unit will not necessarily help as this will lead to other issues such as heat build up.

Yes the steel pins and two resistors rusted as well , so I had to desolder and replace two resistors. My situation was high humidity, in a room where I have a fishtank.

@josh, the resistors on the V3 were through hole, therefore had steel leads on them. The EZ-B camera and the ping sensor have surface mount components, if the leads on these are steel (I don't know what they are) they are completely covered by solder which is tin based and therefore would be protected from oxidisation.

Yes, the V3 could rust in extreme circumstances (to be honest I would put that down to misuse, no electronics should be subjected to high humidity (or low for that matter). At the top end of the range, moisture may increase the conductivity of permeable insulators leading to malfunction. Too low humidity may make materials brittle. This is why most electronics have humidity ratings on them or in the datasheets.) but unless it's being used in those extreme circumstances regularly there should be no problem with corrosion. If it is to be used in extreme circumstances additional measures should be taken to minimise corrosion, much like a car which sits outside it's whole life, it's made of steel (well, most are), manufacturers take measures to avoid corrosion. Changing out components would be a better solution than sealing the unit.

Guys i also want the ez bits so i can connect my camera to my sensor and thing like that which would be hard to do without the bits And Anthony i dont mind waiting a while for the psrts of not in a hurry so even if a have to wait 2 weeks i will becase i cant afford to pay 80$ for shipping .So can you please check for a cheaper shipping method that doesnt have to be very quick Thanks guys for all the help Mohamed

Sorry anthony but 80$ isn't in my budget if any one else can print it with a cheap shipping please let me know
