Cheap 'n' Cheerful Underwater Webcam





Introduction: Cheap 'n' Cheerful Underwater Webcam

This idea came to me today while watching fish in the pond.  I used a flat sided perspex box (a Ferrero Rocher chocolates box), a cheap webcam, a length of duct tape and plenty of hot glue to get up close and personal to those aquatic chums.

I'd already made the box when I remembered Kiteman's Zeroth Law so the photos don't show the whole process.  Remember to set the focus first if you're using a manual focus webcam; I used about 8" (200mm).  The webcam is held in place with 4 dabs of hot glue.  The PSU block is only for ballast, but I needed the tiles too to stop the box floating. Seal the cable entry and the box join with hot glue.

This took about ten minutes to make and I'm treating it as a proof of concept for a more engineered version on a pole to use later in the year when the pond plants have grown and there should be some newts around. 

Warning - Bubbles  coming from the box are a bad sign.  I had to get the webcam out after 20 minutes or so due to a small leak - those boxes are very brittle!

    true, but your warning talked about possibility of a cracked lenses, which can drown it out and maybe ruin a camera. if you cover it up, you may get a worse picture, but it's a small price to pay for camera protection, as opposed to getting a new one

    The warning was about a crack in the box which holds the webcam (and was slightly 'tongue in cheek'), not the webcam lens itself. The box I used was very brittle and may have had a hairline crack already.  The webcam is totally enclosed in what should be a watertight box.

    Ahhh.... The wonders of autocorrection!  (The windows of astrocontortion? ;¬)

    With my webcam the front was flat and there was room to glue around the perimeter without obstructing the lens.  Other webcams may be different, but it shouldn't be difficult to find a couple of glueing points as this bit doesn't have to be watertight.
    The disadvantage of the way I did it was that the webcam turned a bit on the lens and that's why all the pictures are on a bit of a slant.

    Hey so if you do it right you could cover up the license and out won't mess with the picture

    Blimey, I just want to chase the newts around the garden pond with it, not circumnavigate the globe #;¬)

    It's amazing how often those odd shaped plumbing parts come in useful.  I find it's useful touring the local DIY shops occasionally just to see what's available in case you need it at some time.

    Now rewire it to have a 25' cord and do a cut plexiglass case with silicone. Hook it up to a laptop and take it fishing. Better with some cam that has night vision or you can add a few leads. You can use it to see that big bass under the dock and know right where to drop he worm. Or do what divers use to show boat owners add a extendable stick and you can control it without getting wet.
