|I hope that these images give enough information. Maybe the quality isn't that good, but I had to scan them from a magazin that was 23 years old. The input of the receivers is between the AA119 and the 10 nF ( left in the circuit)|

The output that goes to the receiver is at the collector of the BC 547.( text = "naar zenderprint") at the right side of the circuit.
The remarks (handwriting) in the 15 channel transmitter, are adjustments for 12 volt power supply !

INFO about ROV 2005
This ROV will be remote controlled by wires. Just two wires are needed for the connection between the transmitter and the receiver. In fact it works in the same way as RC works, now just by wire. All the electronics are made by myself. Transmitter,receiver, switch channels and several speed controllers. The electronic parts are ready and tested and worked oké.
I started with building the 9 channel version. It worked good, but I had to find out that for me these 9 channels were not enough. So I builded the 15 channel version. I found the basic schematics in a magazin dated: november 1982 ! That's 23 years old. Who collects something, has something. The receiver circuit I had to adjust and I made my own layout. For the transmitter I've used the original printed circuit. The guy who made the original schematic was J.H van Mouwerik.
I can use every normal RC components you can buy, like servos,speed controllers and electronic switches, but I like to build them myself. Now a lot of lathe work has to be done. Gathering all the material , lots of aluminium, took some time. Thanks to my friend Karl-Heinz I didn't have to spent a lot of money.
In total there are 7 motors-trusters planned. This ROV will also have the possibility to move sideways. I've planned to use a webcam for making images and videos, also by wire. For light I want to use two halogeen spots 20-50 watts , and 8-10 super bright LEDs that will move together with the webcam. The webcam and the LEDs will be mounted in a plexiglass dome. A manipulator is also planned. Two small diving tanks are planned so I have no problems with getting the ROV to the surface when I've found something interesting and want to pick it up with the manipulator.
Wondering why I've mounted the joystick on the right panel in a 45 angle ?
Well this ROV has two trusters for forward and backward movement, so it can turn on the spot. By giving it a 45 angle I don't need any mixers to control both trusters. Moving the joystick forward, will give two equal pulses to both the trusters and the ROV will move forward. Moving the joystick to the left will give different signals to the trusters, and the ROV will turn on the spot..... got it ? You have to get used to this control but it gave no problems to me.
I want to make a big box with all the equipment : left panel - laptop - right panel. I think that this gives the most convenient way of looking at the screen and steering this ROV.
By the way the power source will be a 24 Ah 12 volt dry accu that is not inside the ROV. It will also give power for the laptop. Inside the ROV will be a 12 volt 4,4 Ah backup accu, just in case........the wires are cut by accident.
Hope to update this part of my homepage soon..............
