TV Remote Control Jammer
This circuit confuses the infrared receiver in a television. It generates a constant signal that interferes with the signal from a remote control and prevents the operation of the remote.
The circuit operates by generating a continuous infrared (IR) signal that...
Remote Control Tester
Remote control tester circuit diagram. The tester is designed around the infrared receiver module TSOP1738. The operation of the remote control is indicated by a tone from the buzzer. The circuit is sensitive and has a range of about 5...
A Solid State Photodiode Gamma Radiation Detector
Photodiodes convert light into current, and this current can be converted into voltage and amplified. While this process seems straightforward, designing a photodiode detector for gamma photon detection is more complex. Although the circuit is not particularly complicated, the design...
car parking sensor circuit using infra
All distances mentioned can vary depending on the infrared transmitting and receiving LEDs used and are significantly affected by the color of the reflecting surface. Black surfaces greatly reduce the device's sensitivity. This circuit can also be applied in various...
Design your Circuit IR Transmitter
Most consumer electronic devices utilize infrared remote controls for convenient operation. The carrier frequency of these remote controls typically ranges from 36 kHz to 38 kHz. Control codes are transmitted to the device's receiver in a serial format, which is...
Infrared Remote control transmitters
This infrared remote control transmitter circuit exhibits high performance and can be utilized with various infrared receiver circuits. It is designed for ease of construction and cost-effectiveness. Additionally, another circuit is intended for broader applications and requires programming to emit...
IR (infrared) receiver and transmitter
Recently, samples of IR LEDs and a corresponding IR phototransistor were acquired. A project was initiated to utilize these components.
The project involves the integration of infrared (IR) LEDs with an IR phototransistor to create a simple optical communication system or...
General Infrared Remote Controlled Relay
This relay circuit is controlled by nearly any type of infrared remote controller. The circuit operates under the assumption that most remote controllers utilize high-frequency signals.
The relay circuit described functions by receiving signals from an infrared (IR) remote control, which...
Digital Step-Km Counter Circuit Schematic
This circuit measures the distance covered during a walk. The hardware is housed in a small box that can be placed in a pocket, and the display is designed as follows: the leftmost display D2 (the most significant digit) indicates...
