Remote Control Mains Switch
Remote Control Mains Switch
The remote control mains switch is a device designed to control the power supply to electrical appliances from a distance, typically utilizing a wireless remote control. This switch can be integrated into various applications where remote operation...
Inexpensive Remote Watering System
This remotely controlled watering system is cost-effective and easily expandable. It operates in conjunction with a conventional watering timer, enabling remote switching between nine zones. The prototype is designed for use with a bore system, where a deep-well pump must...
A Simple 80M Direct Conversion Receiver
A few weeks ago, Jason NT7S mentioned the ZL2BMI DSB transceiver as a rig that might be of interest for building. He was correct; it had been seen in SPRAT, but for some reason, it had not been seriously considered...
Remote Control Transmitter Circuit
This transmitter can be utilized for multiple applications. An INS8048L microprocessor produces various codes based on keypad inputs. These codes are modulated onto a 40-kHz carrier frequency. Additionally, Q1 drives infrared LEDs LED1 and LED2.
The transmitter circuit primarily consists of...
wireless headphones transmitter
This wireless headphone transmitter ensures a reliable connection over a distance of 2 meters. The oscillator frequency ranges between 1750 KHz and 3500 KHz, utilizing a ferrite bar as the antenna. IC1 amplifies the audio signal, while TC1 serves as...
REGENERATIVE_SHORTWAVE_RECEIVER
The receiver consists of multiple subassemblies, including an active antenna, an amplifier featuring regeneration control and band-switching circuitry, an AM detector, a power amplifier, and an output device such as an internal speaker, external speaker, or headphones. Additionally, it is...
Remote controlled LED
The remote control transmits encoded signals. Each time a key is pressed, the relevant code is transmitted, usually repeating it many times to ensure reception. This encoded signals travels over a radio or infrared-light beam, to eventually get captured by...
Simple Valve MW Transmitter circuit 30W
The simplicity of this transmitter, combined with its high performance, makes it particularly interesting. It has an output power of approximately 30 W, and under normal conditions, with the appropriate antenna and handling, it can achieve a range of 30...
Linux FRS Radio Control
This is a simple hardware computer interface and Linux program that can be used to control the most commonly used buttons on any consumer Family Radio Service (FRS) or General Mobile Radio Service (GMRS) radio. There are 22 available FRS/GMRS...
