  1. That's the stuff I was hoping to find. The original intent was always to bring the video feed through the umbillical. We actually have a 100ft length of professional ROV umbillical. (neutrally bouyant, actually pretty high tech) The pros use thousands of feet of unbroken cable. If it gets cut near the end, (the last couple hundred feet) they will cut it and throw it away. We got them to send us a "scrap" This cable is video ready, and the plan is to use as few wires as necessary to drive the ballast tanks, the drive motors, and the camera pan/tilt. I like the direct parallel port dr
  2. I appreciate the replies, not exactly what I was hoping for. We have to have an umbillical (cable) to control the motors on the ROV anyway. We will probably be at least 20 feet deep in salt water. I was hoping there was an easy way to fool the servos so that we can use direct wired switches or something. The cost to purchase the transmitter and receiver just for camera control is prohibitive for a donated/volunteer project. Does anyone have detailed technical specifications on the signals that drive the servos? I am an electronics tech and can probably come up with an inexpensive
  3. I love the elegance of the Pan-Cam. My question concerns going the other direction. Underwater! I have been tinkering with making a pan-tilt camera mount/housing for a middle school so they would have an underwater camera for science fair projects. In case you don't know, you can't transmit RF underwater. With that serious handicap, my question is: Has anyone built something that I can use to transmit the signals to servos over a wire? I'm open to suggestions on what to use for the control sticks too. I would assume a potentiometer with the wiper on a lever. Maybe a video game co
