A while back I was looking around on the internet and saw someone's home built ROV. I thought to myself that I could never build that. 3 weeks later, I had built a fully functional ROV. An ROV is a Remotely Operated Underwater Vehicle, and I have built mine to explore an old town under my lake. The ROV costs roughly about $150, depending on what materials you want. I still have to work out some bugs on the tether and I still have to finish the camera setup. It has taken Longer than I expected to finish the camera stuff. Check out the most recent video of it here: http://www.youtube.com/watch?v=xRWh7HqtBPA . Sadly, I didn't document the process until later in the project.
Step 1: Starting the project
To begin your project, you have to sketch out an idea. I had a pretty simple design. Also, you will want to get your pvc as your maine material. Here is what you will want to have for the project:
Hot glue gun
Hammer, screw driver...ect.
Hot glue sticks (100 pack is best)
16 feet of 3/4 inch PVC
8 three way elbow connectors
4 T connectors
Webcam, Gopro, or any small camera
PVC tube for camera (I don't have the dimensions)
Duct Tape roll
Hardware mesh screen
3 three volt motors
3 DPDT switches
Floats (Pool noodles work best)
300 feet of 14 gauge wire (Doorbell wire works best)
Sheet of Plexiglass
3 "D" battery holders that hold 2 "D" batteries in series
6 "D" batteries
A lot of time and patience!!!
