hope you get every thing back home in one pice and have a safe trip!!
I was hoping to get mine in the water in a few week's from ripping it to bits for the re build, but It doesn't look it will be in the water this summer ether, sort one prob then find another now one off me thrusters doesn't want to work!! oh well going to be ages learning how to program the uno, but get there in the end!!

DNA,
Thanks!
Hazzy,
Keep at it! These things often have a way of working themselves out in the end! As always, if you get stuck with the Uno, I would be happy to assist!

thanks KR2
will keep at it and you have helped more than you probably know mate, I'm starting to understand your uno programing you have done so hope it wont be to long till I can modify it to do what I need, which is nothing like as complicated as what you are getting it to do.
so thanks' again, and no doubt I will need your help at some point!!
Ben

So, even though the final build may not be on track to finish this millenia, I am still pushing forward with the code and some of the other key components.
This week I recieved my custom 3D printed thruster housings, and worked out a few more bugs in my code!
Thruster housings can be seen
here.
Here is a sneak peak if you can't be bothered to jump over to the other thread!

Damn Ryan
I've spent the whole day looking at DIY 3D Printer builds.......then started looking at DIY laser cutter builds....
I'll never get my ROV built at this rate!
Awesome thruster housing, by the way....

How do you keep track of the batteries not to run low?
Thought about using 3x parallells connected 12v 3s 5000mAh batteries. Any ideas / tip?

I am using a cheap hobbyking OSD module. It overlays the battery voltage directly on your video feed.

Darnit, here i go an order a currentsensor to monitor the mAh bugging the irc channel to learn how to implement that into the system and i could use something that easy. Well..
Code: Select all
int currentSensor_pin = 10;
long currentSensor_lastCheck = 0;
long currentSensor_lastValue = 0;
long currentSensor_currentUsed = 0;
void loop() {
currentSensor_lastValue = analogRead(currentSensor_pin) * convert to ampere * 1000;
int timeDiff = millis() - currentSensor_lastCheck; /* Time since last check */
int timeDividor = 3600000 / timeDiff; /* How many yimes the diff can run in a hour */
currentSensor_currentUsed += (currentSensor_lastValue / timeDividor); /* Get the mah of that specific time area */
Serial.print("Used mAh = ");
Serial.print(currenSensor_currentUsed);
Serial.print(", battery is 3x500 mAh, 80% of 15 000mAh is 12 000mAh.");
/* 80% should be full stop */
}

They are pretty simple to hook up. You can also get them with a 3 axis magnetometer built in to give you a compass heading so you do not lose orientation while submerged.
