Camera hood and fan

In this post I'm going to examine how I made the camera hood and fan.

This is the camera hood and fan design I use to prevent condensation on my camera. The fan is quite effective, until the humidity gets too high.
I use a variety of materials to make this, as follows:

2x Cardboard Box
80cm Computer fan
Metal coat hanger (wrapped around the open end of cone)
Power supply or 6-12V battery (I adapted a universal power supply)
Large Bin bag
Duct tape or glue gun
Twine or string

To make this I just used trial and error. It depends on your camera’s field of view as to how wide your cone should be. However it is likely that you will want to create the cone as an oval shape as most cameras have a wider field than height.

Once you have worked out the approximate shape of your cone, attach the metal coat hanger to keep the shape of the end of the cone. Finally cut a hole at the top and attach the fan, pointing at the lens of the camera.

Once that was complete I attached the bin bag as to cover the camera completely to prevent light showers affecting the equipment.

Here’s the diagram:
