Omnimeter
 

By popular demand...

Now you only have to figure out how the thing works...

Have fun...

Hi, what a nice steel tool, impressive :up:

I think I read how a shot was screwed up by reading off the wrong periscope power scale, and here is the very scale to ponder. Thanks for the pictures.

Most cool Gino.

I'd say it works like the stadimeter. Pick masthead height, count the number of divisions (in either x1,5 or x6 scope) and slide - then read off the distance on the right side of the scale - Simple and fast.

is there ANY possibility that you can put that thing into a high-res (or even low-res) scanner and provide the scanned image to us?

Something more about 'the tool'. It's quite heavy, but the sliders go really smooth. Mind that this is a handmade tool. The quality of the craftsmanship is beyond anything you can get nowadays.
How do I know that it's handmade, check out one of the pictures. The craftsman made a mistake... instead of 10,000 he first made 9...
It's also made for the boat that's named on it. Every boat built by Electric boat Co received (amongst other things) one of these.
E-boat Co also gave the submarine a number of playing cards. These were especially made for submarines. The red Hearts and Diamonds were printed in a different way. We are currently searching for the design of the back of these cards, so we can reproduce them.

Anybody here that can help us?

groetjes,

I'm working on that. The president of the USS Cod Submarine Memorial is recovering from surgery. He has the Omnimeter at home. I will contact him this weekend to see how he's doing, and I'll tell him about your request. Please have patience, the answer may take a little time...

Groetjes,

Excellent
 

Gino;
thanks for that.

I've managed to create a virtual omnimeter in HTML format. You can slide the appropriate parts just like the real thing etc.

The only problem is that I used the images as currently provided by Gino which are off-angle and difficult to line up despite my trying with my graphics program. I've asked Gino for a straight-on shot or a scanned image which will resolve the issue. The only other option is to manually input all the line graduations which I don't have time for at the moment (too lazy, LOL).:yawn:

If Gino can get the images then I'll finish it up and post for DL within the next week or so (that will include testing during the game to see if it actually works).:salute:

Very cool gadget.

Gino - not to hijack your thread, but can I request your expert opinion on this?

The red needles on the diving gauges... It's correct to assume that they were used for steering correct depth, since they are on the gauges for shallow depth and that they are on both the gauges for both planes-men.
I think that the needles (they are 'adjustable') were set however the commander of the boat, or the diving officer wanted them. So, one for the attack periscope, and one for the observation scope. With the introduction of radar, that may have been used also. On the Guppies they may have been set to the snorkel depth, etc.
That you see different readings on various boats has a simple reason; people have adjusted them for whatever reason. The painted ones could have been made because the needles were missing, or the gauges had not been equipped with the needles. If you look at "The Fleet Type Submarine" you will find a drawing of the dive control station with gauges that do not have red needles. This could mean that this was a modification that was introduced during the war, or just after.
What they are currently set to is up to the discretion of the shipkeeper...

Groetjes,

Really cool device!:cool: I wonder if it could be added to the game as a "dial" on the overlay such as the stopwatch?:hmmm:

Now...what a great idea... I think you'll notice that some people are already working on something.

As for the device: I only know of it's existence, I held it in my hands once, and I have an idea of how it works ( I also know the source to go to if I don't...)

Groetjes,

OK,

so I have some more pictures. Although htey're not what you wanted, but I have some good news.

Somewhere this week I should receive scans/photos made from the front.
For this the Omnimeter that we have has to be disassembled.

Groetjes,

Thanks.
 

Gino;
appreciate your efforts. Can't you just remove the two 'knobs' and lay the whole thing down in a scanner?
I'm not sure if it will be too reflective given the shiny surface. Good luck with that. I've got my little html application standing by and if the scan works then it should just be a simple cut and paste into the application.
:salute:

Hello,

how the omnimeter works is very easily, and can be used as substitute for a broken split prism stadimeter by using the marks in the scopes (At 6x zoom 1 big mark= 1 degree). You simply drag the sliding part and place estimated mast heigth opposite the measured numbers of marks in the scope at high or low power (thus the double scale) and read in the distance scale the resulting distance to target opposite the same mark but in the range scale. The Sine scale on the right allows doing the same with hull length instead of mast heigth, and the sine scale serves for correcting for the shortened hull size when the target is angled.
