Koi Cam- outdoor webcam for submersion in pond? Answered
I would love to try to build a webcam that I can submerge in my pond to transmit video of koi swimming in my pond. My idea is to place a marker outside of my garden pond that someone can scan using Aurasma (augmented reality program for smartphones) and then show a live feed of an underwater camera of the fish swimming in the pond. I thought about simply using a very cheap small usb camera, seal it in a clear waterproof case and run the wire outside the pond. The problem is, I don't want to leave a computer (even a old one) outside running 24-7 to plug into and power source is a bit of an issue even though one outlet may be available. I thought of using a wireless or rechargeable webcam, but i don't want to have to pull it out of the pond constantly to recharge it and i don't think i can transmit far enough for my main computer's wifi to grab the video if it is underwater.
Does anyone have any ideas or suggestions? i am trying to do this super-cheap... so want to avoid any costly options...preferably less than $50.
