Road remote control switch production
The production of this wireless remote control switch is relatively straightforward. All component parameters have been tested and verified. The installation of the reader component parameters can be completed during production, including the soldering of resistive and capacitive components onto...
Low Power Wireless Audio Power Amplifier as baby mointor
This appears to be an infrared (IR) transmitter. IR signals do not penetrate walls, and it is assumed that this device is intended for use in a room separate from the one in which the user is located, rendering it...
active short wave antenna
The circuit presented illustrates that despite the availability of various new components and technologies, it remains feasible to design useful and interesting circuits. The circuit utilizes two well-established transistors, the BF256C and the BF494. Along with the necessary resistors and...
DIY kinetic energy harvester
A DIY kinetic energy harvester utilizing the electromagnetic method to generate electricity. The materials that will be used are currently known.
The project involves creating a kinetic energy harvester that converts mechanical energy from motion into electrical energy through electromagnetic induction....
Schematic of The Infrared Rays Wireless Headphone
The transmitter circuit for inductive headphones must be installed on a wall or ceiling, limiting their use outdoors. This is a significant drawback of inductive headphones. In contrast, infrared wireless headphones do not have this limitation; their flexible infrared transmitter...
Amatorki projekt
The circuit is designed to add two identical branches to the existing despreading spectrum. The only difference between the branches is the phase of the PN sequences fed into each branch, specifically at the input of a double-balanced mixer. The...
MINI_ATV_TRANSMITTER
This low-power NTSC video and sound transmitter is suitable for amateur radio, video handheld transceivers, remote control applications, and surveillance purposes. It features a crystal oscillator-multiplier and a power amplifier. Video modulation is achieved through a three-transistor series modulator. The...
Q-Multiplying Loop Antenna
This circuit is designed to be used in conjunction with the standard 4 foot square loop used in MW for long distance reception.
The circuit described is intended for use with a 4-foot square loop antenna, which is a common choice...
RF Remote Control Switch Rx-Tx circuits
This circuit includes a 2048 radio remote control transmitter and a corresponding wireless receiver that features high reception sensitivity and low power consumption. The combination of these two components provides a highly reliable remote control system, suitable for various applications...
