blibecap 29 Posted July 16, 2010 Here is a quick update on the project. We have the circuit design complete and working. I have purchased the surface mount components as well as the PCB for 25 initial units. We have assembled, tested and calibrated three units for testing purposes are currently in the testing process with two units for testing and a spare. After 1 week of diving we haven't seen any problems or had any failures in either of the two test units. It is a very reassuring feeling to look down at the housing or in the eyepiece and see the little green (I'm OK) led flashing. Some updates on the unit. The size is 1" X 1.5" and about 3/8 inch thick including the battery. If you don't have that much room there ia a option for a remote battery that would cut the thickness in 1/2. We have the current units installed in a Ikelite housing for a Nikon D90 and a Sea&Sea housing for a Nikon D300. We are still working out the installation procedures as well as the options and cost but re still on target for a complete setup to be in the range of $500 or less. All of the external fittings are stainless steel and the battery is a very readily available 2032 coin cell. The board has the options for two red (danger low vacuum) led's as well as two green (I'm OK, safe vacuum & dry) led's. The board also incorporates a moisture sensor that overrides the vacuum led's. I don't see any reason that this system couldn't be incorporated in a video housing as well as a still camera housing. As stated earlier in this thread the design is proprietary and the PCB assembly is made of surface mount components so that will only be sold as a assembly. The blocking plug for the vacuum fitting is custom made but all the other parts (vacuum fitting, vacuum pump and inlet connector) are available over the counter. We hope to be able to start delivery of parts kits as well as preform turn key installs in August. If you are interested or have questions please feel free to ask and I will try my best to get back to you. Share this post Link to post Share on other sites
