It's worth it Mark...I'd try and describe it, but we'd be here for weeks if I did, but when Ron describes it, to quote the great Roger Waters...."it all makes perfect sense"

Haven't got a Version 8 cam. Recommend you follow the description on the chucklohr website, which is generally spot-on-

This my home brewed 808 camera case designed to go on to my TT Neptune...the rear case is a section of an old Models By Design torpedo (made to go with the Biber kit) the lens cover is an aerosol deodorant can lid with a hole drilled in it and the clear lens is a piece of thin plastic sheet. The clear lens will be glued into the lid using silicone sealant, the camera simply pushes into the rear case and is held in position with foam, and the whole thing is sealed against water ingress by a few layers of plastic insulating tape. The case is just held on to the Neptune with a large elastic band around the body, but it will be fitted properly to the guard rail once my hands have settled down and the swelling has gone down.

Quite probably E2V, I used what I used 'cos it's what I had laying about doing nothing, but I see no reason why you couldn't use Kinder egg cases...if the camera would fit. Next time the grandkids are over,  grand dad will be buying kinder eggs...

:) good plan.... feed them to the grandkids as they taste foul lol

I'm sure the kids have some lurking in their rooms (the girls a terrible hoarders of junk lol) so Ill grab some measurements for you.
Just to confirm, is this the same camera as yours?

Its a veritable minefield as there are 100's of cameras that look the same as your one but have different resolutions etc

That looks about the same one..I've had mine ages, so I don't know which model mine is, but I think the external measurements are the same.

Hi Ken

unfortunatley I am working this sunday so wont be down this weekend.

@ essex2visuvesi  yup thats the one only the one you are linking to is a later model than mine

@ U-33  Rich if you want to find out a lot more about your key fob cam then just follow the link that Andy posted a couple of post ago the site is a gold mine of information on these cameras so much so I have now
              corrected the time and date on mine.

@  Subculture Andy thanks for the link now sorted

Regards Mark.

All the 808cams use the same case, the only way you can tell what version you have is when you record some footage. That's why it's important to purchase the camera from the vendor I specified.

I think the Kinder egg capsules will be a bit small for the cams. The short but fat shape of the 808 isn't ideal for constructing an enclosure. With the ones I made, I did my best to make one that was as streamlined as possible, as past experience with running actioncams showed that the handling of smaller boats was upset considerably when piggybacking one.

Literature says that an aspect ratio of about 6-7:1 is optimum. Needing an enclosure of about 35mm diameter, that would have dictated a length of at least 210mm (over 8") long!! Some other reference material suggest an optimum ratio of 4-5:1. That gave an enclosure length of 140mm, still larger than what I had hoped for, but as the front was truncated by the front lens, that sounded more manageable. The enclosures I made ended up with a slightly stubbier nose than first built. I had to create a larger window as I noticed vignetting when using the HD 808, which has a much wider aspect ratio than the SD 808's.

There is sufficient space inside the pod for add-on lenses, although if using the HD 808, I find the standard FOV is wide enough.

For a bit more insight on how the Swann type video camera-transmitter system works when applied to r/c submarines:
