Putting a camera underwater was another realm to conquer, and having two young children who love the pool gave me a great reason to work on this.
The purpose of this Instructable (my first) is to detail how to build an underwater video camera housing. The end result will be the ability to take underwater video on the cheap - less than $50, significantly less if you have parts on hand.
It took about 3 days to complete this, but most of that was testing for leaks or waiting for the sealant to set. Actual workbench time was less than 2 hours.
My inspiration for this project comes from these Instructables:
The first showed me how easy and inexpensive this could be, and the second set the bar for aesthetics. Thanks to both Kipkay and Bobby_M! I want to give credit where credit is due.
Step 1: Parts & Tools
1. Igloo (or similar) insulated water jug - $4
2. Sheet of Lexan or Plexiglass - $5 (enough to make several lenses)
3. PVC fitting, threaded at one end, flared at the other, about 2 inches across - $3
4. Fast Cure 5200 marine-grade adhesive/sealant - $5 (way more than needed)
5. Teflon plumbers tape - $??? (way more than needed, had it on-hand)
6. Industrial-strength Velcro - $10 (way more than needed)
7. Pair of metal door handles - $5
8. Two metal bands (type used to connect rubber hoses), 5" to 7" fit - about $5
9. OPTIONAL - water sensor - $10
I purchased all the parts except for the water jug at Home Depot. The water jug I bought at K-Mart, but I have seen the same or similar just about everywhere, from Target to CVS. We even have one at home that is easily 25 years old, so it should be fairly easy to find one that works for you.
Video camera that fits the water jug
1. Electric drill and bits
2. Hole saw of approximately the same size as the flared opening of the PVC fitting
3. Hole saw of same size as threaded end of PVC fitting (if different)
5. Cap from a can spray paint (an old one, as this cap will be destroyed)
6. A place to test for watertightness (I used an old 5-gallon paint bucket with a lid)
7. Heavy stuff to hold the lens in place while it sets and, if needed, to hold the lid on your test chamber
