The single core has a reason it is almost impossible to be sure that your epoxy gets in between all the wires of a multicore wire. While water pressure is a sure way to find any crack between the wires. You could use just a short piece of single core and solder a regular wire to it outside the pene...

Hey, I'm thinking about to use the Blu Robotic Watertight Enclosure for ROV/AUV (4″ Series) https://bluerobotics.com/store/watertight-enclosures/4-series/wte4-asm-r1/ So, the first challenge will be to get a water tight connection from the BLDC-Motors inside the Hull. The Blue Robotics Penetrator ar...

Thank you.
I'm almost done with my Rover Projekt.
The Full Duplex Communication working good. Only the Live View is a little bit noise.

All good, did two things wrong and I think one Balun was broken.
Now it's working fine only the image quality is a little bit bad.
I see a lot of ants in the Screen.

Hello, at the moment I'm testing my ROVER. On the ROVER a RunCam Swift 2 is installed. The Cam working fine in FPV Mode by wireless transmitter. But now I installed the CAT5 Cable (75 m long) and on both ends a Video Balun. This one here from Banggood: https://www.banggood.com/de/2Pair-HD-720P1080P-...

I have maybe stupid question. I using the MAX485 Bords and I power those boards and both arduinos with a seperate power source. So the only connection between the two systems is the wires A and B. Is it necessary to connect the GND together. GND from arduino Master to GND Arduino Slafe? http://www.t...

Hi! I use techmonkey based code modified for my own needs, easy transfer protocol, and RS485 boards that don't need control lines for the tx/rx switching. I had no end of problems with the cheap rs485 boards and went for slightly more expensive boards that detect when you TX and do the switching fo...

I also try this example out https://naylampmechatronics.com/blog/37_Comunicaci%C3%B3n-RS485-con-Arduino.html And it works fine. Servo is driving exactly the analog input of the master. I'm not sure what example I have to use for the thusters. I see here many examples. The http://www.techmonkeybusine...
