Glass bottom video boat?

[BoyntonStu]

I would like to build, buy, or modify an r/c boat to have a flat glass
portion of its hull.

My intention is to carry a video camera, transmitter, LED lights, and
batteries.

High speed is not required.


Suggestions please.

hi im not really that up on boat hull types, but what your doing is
something i thought about in the past. i think you will need quite a
heavy hull to keep it stable you'll probably get away with just making
up pretty much anything with a flat bottom. what type of camera u using
i thought about a small digital camcorder but its alot of money if it
gets wet. my other idea was a small radio transmitter camera you can
get on ebay really cheap and picture quality supposed to be good, that
means you can keep the expensive stuff on dry land.

One of these Cameras with built in flash memory that are splash proof
might be a better option?

I have one of the 2.4ghz transmitter types of cameras that I purchased
from ebay about a year ago. Whilst the picture isn't too bad and it is
relatively lightweight, I found that it smashes through batteries like
nothing else, I am lucky to get around 5 mins of video from it before
it really starts to get major static in the picture. Also, those
little spy cams don't record, only transmit a picture so you will also
need a recording device, either a capture card on a laptop or a digital
camcorder which is what I used.
If the camcorder was small enough and the boat stable enough, it
wouldn't take too much to rig up some sort of waterproofing for it,
there are many methods out there that I have seen that are quite
ingenious really, one of them uses a small perspex disc and a plastic
bag, and from what I have read, they swear by that method as a cheap
way to get your camcorder underwater.

The 'boat' need not be 'boat' shapped.

An r/c inner tube carrying a glass aquariam would do it.

Also, any crude jon boat shapped hull, etc.

All the video equipment, transmitter, LEDs and batteries inside the
semi-sealed aquarium.

The aquarium could be about a foot inder the surface.

What would make a good 'donor' rc for the motor, etc?


This project has my juices going.

We used to make quick and dirty R/C boats out of those cheap foam
"surfboards" they sell for kids to paddle around on. (About 2 feet long
or so.) You can cut out a hole for a glass or plastic box with a hot knife.
Poke a hot brass tube through it at an angle for a stuffing box. (Keep
the motor above the water level and you don't need to actually stuff
it.) Pockets for batteries and stuff can be scooped out with a hot spoon.

Wm,

Thanks,

No stuffing box needed. Going with an airboat so as not to disturb
the fishies or alligators ;>)


Have you done any wireless video?


Would a cheap generation or 2 back 72 Mhz FM or PCM transmitter be OK?

Recommendations, please.

In most locations 72 Mhz is an aircraft only frequency. DO NOT use it
without checking local laws/regulations.

Surface freq. systems are available for very reasonable prices new.
Used are even cheaper.
