HydroHacks

Low-impact, accessible devices using minimal new equipment, reusing and recycling where possible. For use by swimmers or from vessels such as the Contingecy Research Platform. Undertaken at your own risk.

Included here are a waterproofed webcam and a waterproofed hydrophone and recorder. See also Kilnertography

Waterproofed USB Webcam

 

 

Source a redundant or cheap USB webcam and 'pot' it in a suitable casing to make it waterproof, as follows:

Break open the plastic casing and discard.

 

 

 

 

Cut the top off a plastic bottle.

Insert the camera component into the bottle with the cable coming out of the neck. Fill the neck space with hot glue or silicone bathroom sealant.

 

 

 

 

Ask a local glazers to cut a piece of glass to fit the opening of the bottle neck.

Fill as much air space at the front of the opening as possible - here done with silicone - then fit and seal the glass with more sealant.

 

 

   

Attached to a laptop (suitably waterproofed, depending upon the length of the USB cable) you can now make films within waves, ponds and rivers.

Waterproofed Hydrophone

To make a waterproof listening and recording device for underwater.

 

 

 

 

 

Source a cheap or discarded MP3 voice recorder. This device came with a microphone and headphones.

 

 

 

 

Find a small bottle with removable cap. Drill the cap with a hole big enough to feed through the microphone lead.

 

 

 

 

Fix /seal the cable and microphone in place with hot glue on the inside and outside of the cap.

Fill the bottle to the very top with vegetable oil and put on the lid - immersing the microphone in the oil.

Try not to allow any air bubles to stay in the bottle. It wants to be as full as possible with oil.

 

 

 

 

 

You can use parts from heavy rubber gloves to make a casing for the device. Hot glue and cable ties are useful to seal the glove sections.

Cut to size depending upon your components. Ensure and test any waterproofing to the appropriate depth before using, otherwise your devices might not survive.
