Can someone tell me how to make a remote controlled  device? car or boat?

Well, detailing the entire process here would probably be too in-depth.  May I suggest that you visit a local hobby store and ask a salesperson about a remote control car/boat kit?  This is probably the best way to learn and understand the principles first hand.   If you want, there are even kits where you can build your own transmitter and receiver.

Try using an airplane, a navigational wheel, or something along those lines.

connect the jump start leads of your landrover to the nearest powerstation, and the other end to your asssss\n\nthat should have you jumping like a joey....

about a 100 or until they invent flying cars, i want to drive one of them things

make anything out of the following\nperiscope\nvolcano (Although I don't suggest this - it is a very old project and maybe many will turn up using this)\nA mini hovercraft or hot air baloon (info can be found on net)\nI don't know what it is called but if you know that thing in which we have to take a small hoop across a wire (which is not straight) without touching it. If touched, it will make a sound.\n\nIf none of this suits you, you might watch Backyard Science at National Geographic Channel

Go to peacefire.org. There, it shows you how to make your own circumventor thats based from your home computer.

A very simple method would be to take a rubber band and anchor inside the body of the car on a hook and stretch it the length of the car and out the back (if you want toe propeller to push) or out the front (if you want the propeller to pull).  \n\nGet a propeller and attach some kind of hook to one side of it (a hook or loop, could even use flexible wire).  You'll need someway to keep the propeller from getting stuck, so you'll want to hold it away from the body using a bushing or other method).\n\nOnce you've connected the rubber band on both ends, just turn the propeller to twist the rubber band, and release to cause the propeller to turn.\n\nThis is simplistic, but gives you a general idea.  You'll of course have to have wheels, and a good method of reducing friction on the propeller and shaft.

3 easy steps:\n - Build a car.\n - Power it with a rubber band.\n - Wind it up and let it run.\n\n\nGood Luck!

You need a chip to interface with the motor. You also need a receiver on board the boat. Basically you have to control the motor's speed and the rudder. For that you can get a motor out of a toy plane.\n\nwww.internethobbies.com/internethobbies/radconboat.html\n\nThe above link might help\n\nYou can build a better boat if you can program the chip. It can then chart a pre configured path.

1. Build a really big sail\n2. Magnets (think of the magnetic trains that Japan uses, however the whole roadway would have to be made with magnets to pull this off)\n3. Using Pascal's principal of compressed liquids you can probably make a peddle system (Brakes and most powered steering systems use Pascal's principal, source 1)

Take a plywood board. Fix a rectangular (50x12 mm) wooden rod of about 600 mm length with it so that when board is horizontally placed rod is vertical.\nMake a hole in vertical rod at about 25 mm below top. Fix a small ball or roller bearing in it. Fix a small rod through bearing and mount car radiator fan blade on one side and a small tape recorder pulley on other side of it. On the side of above pulley (used in tape recorder) make a fixing arrangement (with vertical rod) below above pulley and mount a tape recorder motor on it.\nJoin pulley of motor and pulley on which radiator fan blade is fixed using belt used in tape recorder drive. Since tape recorder motor is a DC motor it acts a generator also.\nConnect wires of motor (generator) to a voltmeter/ lamp.\nPortable wind mill is ready. This is a practical working model of wind mill. It has been displayed in science exhibition.\n\nAs regards increase in output based on number of blades, you are aware that wind mill changes kinetic energy of wind into electrical energy. Kinetic energy of wind depends on velocity of wind and contact area of blades. So try and find out truth for yourself. You have to work to learn.

Someone with the ability to make & pilot a boat. :P

you can attach a fan to the motor and then strap it on to the car. you can um attach something flexible to the motor, and put it on the car sideways, so that it pushes the car along. you can tie a string to the motor, and then run that string to its wheel and wrap it around the wheel (or the axle for the wheel) and then the string wraps around the motor. lotz of wayz. prob need more info though.

Try this. It's a tutorial on how to do one (below).

Remote control cars have circuits inside which respond to the radio frequency signal sent out by the controller. It will control the motor speed and direction, and control the steering motor.  Batteries provide power for the control circuitry which delivers it to the motors in the car.\n\nThe controller is a radio frequency transmitter which sends varying signals to the car.  The signals depend on the position of the control sticks on the controller.
