Remote Controlled Surveillance Robot

Image
This post will provide you with the basic information on how a remote controlled vehicle can be constructed. Read on to know more about this. The components required to construct the vehicle is listed below: 1.2Ghz 1000mW Receiver+Transmitter USPS Priority Mail boxes Hitec Optima 6 2.4Ghz Receiver Arrowind 18A Brushless Speed Controller 2200mAh 20C LiPo Battery Pack Brushless motor Custom motor-reversing relay board Foam wheels 7-Inch Handheld LCD TV Servo The first thing to do here is to test the wireless transmitter. All the required components are mounted on the USPS mail box. Once the test is done, the box is strapped onto a nitro RC truck. The vibrations caused prevents the truck to be driven via the wireless video feed. The best thing to do in this case is to add wheels and propulsion to the box.

Remote Solar LED light Circuit Diagram

Image
Introduction I created this circuit in an attempt to make the simplest possible solar powered project. It would make for an excellent science fair project, and would also serve as a good introduction to solar powered circuitry. It may also have some practical uses, such as shedding some light into a dark part of your house. The idea is simple, the solar panel converts sunlight into a trickle of electricity. The electricity is used to run a white LED. Specifications Operating Voltage: 3.7V DC Solar Current: 25ma max. LED Lamp Operating Current: 10-25ma. Theory The remote solar powered LED light takes advantage of the current limited nature of solar photovoltaic cells. If light shines on the solar array, current will flow through the circuit. For a typical size of solar cell, there is a maximum current that can be produced. The maximum solar cell current is simply matched to a value of current that the LED can handle. If there is enough light to raise the solar panel's voltage ab...

Remote Control Mains Switch Circuit Diagram

Image
This is the simple project of Remote Control Mains Switch Circuit Diagram. As the only electronics engineer in my  =family and circle of friends, it is some-times not possible to evade an appeal for help. This time the request came from a friendly elderly lady in a retirement home. In her room the light switch by the door  and the pull cord above the bed operate the light fitting on the ceiling in the middle of the room. However, she would prefer that her standing lamp was operated  by these switches instead, since she does not actually have a light fitting mounted  on the ceiling. This standing lamp has an  on/of f switch in the power cord and is  plugged into a power point. However, it  stands rather far from the bed so that she  always has to find her way in the dark. A  wireless operated power point is not really  a consideration, because it is just a matter of time before the remote is lost. Or maybe not?  Remote Control Mains ...

TV Remote Jammer Using 555 IC Circuit Diagram

Image
The TV remote control transmits television signals as pulses of frequency around 37.5kHz. Each button on the remote control is pressed or equivalent has a pulse signal codes. This remote transmits pulses of the circuit block of the same frequency as the remote to your TV confuse decoding the transmitted signal. The heart of the circuit is the 555 timer IC in astable circuit works mode.The output series of pulses at a frequency of 18 kHz to 48 kHz by simply adjusting the 5K potentiometer. What you do is adjust the potentiometer until frequeny jives to its distance from the TV or until the signal is ignored by television.  TV Remote Jammer Using 555 IC Circuit Diagram Read more IC Circuits

Radio remote controls for toy cars

Image
Playing cars that are controlled via radio signals is an interesting game. The much-loved toy cars children, plus a simple circuit will be the ideal toy car. This circuit families use traditional digital CMOS IC which requires very little electrical current, so it will not burden the original toy car performance. In this system, radio signals are not transmitted continuously but only generated when the controller sends a command to the left / right or forward / backward, and even then only a radio-frequency discontinuous, so is sending pulses of radio wave frequency. The number of pulses sent represent commands sent, GO command is represented with 8 pulses, is represented with 16 pulses LEFT, RIGHT DOWN 32 pulses and 64 pulses. Commands that can dikirimk is a combination of 2 orders once gus, which is a combination of command forward / backward and right / left, for example, could be sent forward orders and left once gus, in this case the number of pulses sent is 24, ie the sum of the ...

Telephone Operated Remote Control Using PIC16F84A

Image
This design controls up to 8 devices using a PIC microcontroller (PIC16F84A) connected to the phone line. The unique feature here is that unlike other telephone line based remote control, this device does not need the call to be answered at the remote end so the call will not be charged. This device depends on number of rings given on the telephone line to activate/deactivate devices. Set the DIP SWITCH as follows: Switch RA4     Switch RA3        No. of initial rings to Switch ON(activate half of the board) OFF        OFF             2 ON         OFF             4 OFF        ON              3 ON         ON              5 T...
