How are the motors controlled? On/off mode or some kind of scaling behind it?

Thanks X !

the motors cannot be replaced but the gears ratio can !  i have it set at low now which gives tremendous torque but not much impressive speed ( as you saw in the video ) but that is good in a way or another :) the concept should come to life soon .

@arithma , its forward/off/backwards for each side of the tank with no proportional control

@bashlogic , it is USB ! :)

Thanks Ayman :)

^^ it seems to be balsa wood, easy to cut with nothing more than scissors and VERY light.

anyways jad, when will you cut this wire and start using something wireless? maybe a bluetooth receiver and an app on your cellphone to control it? you have experience with adruino, you shouldn't find any difficulty in making it.

Thanks GN yes , it is made of balsa wood , and the thickness i used cannot be cleanly cut by scissors  :) i used a mini saw . Battikh , the tiny wire is an antenna notice the RX inside the tank  , its already wireless :)  i only need to hook up the TX to the computer and it will be a complete system .

Thanks flakk , the PCB's are from EKT jnah

you cant learn soldering online ! , you need to practice , go to katranji njah , ask him about the KITS , they come complete with a circuit board and component placement sheets , also get a soldering iron and some solder and practice on those boards ! :) . your hand will most definitely shake will soldering your first hundred joints :P , but after that all will be easy . i have been professionally soldering for about a year now , learned on my own and you can see the tiny SMT component that i managed to place with no heat gun ;) but with an extremely steady hand and a magnifier lens . the wood is from fairco , kornish il mazra3a , he has many sizes . btw EKT does sell project boxes , which i will get for the base station once everything is done :-) , download a program called fritzing , it is pretty easy to use and design simple circuits and even print them ! , i have never printed my own circuit yet , but will eventually do . will post about that here ofcourse ! :)
took out the RX and TX from an RC toy car ;) , your problem with them was because you were using breadboard , you can never get a consistent terminal contact with them !

you design the layout on a specialized software (like freepcb if you want to go for something basic and opensource), print it on a piece of paper (with the correct scale) and give it to EKT, they will print it on a board for you.

hmm so i need to send my project to ekt i never tried that before i thought he was using the mekweye technique :D do you have any ideas the cost and does they do this quickly or they need 1 day or 2 to print it

you are welcome ! :)

good idea , although i don't like the mess the water makes ! :) besides , have you heard of skid steer ? its the method my tank uses to turn and can be applied in water as well ;)

yes skid steer can be used for inverse rotation of the axis which will give u total control for the tank in both ground and water

very nice.. now try making something useful, like a big antenna to provide us with decent internet
