ElectroSuite.com - Simple Wireless Remote Control Switch. The circuit of a FM wireless remote switch presented here is very easy to build and can be used to toggle a load anywhere within a radial distance of 50 meters.
ElectroSuite.com - Circuit explanation of RCC with LSD. In the case of Japan, the radio of standard time is transmitted as long wave radio from the transmitting station in OOTAKADOYA mountain (40kHz) of Fukushima Prefecture, and HAGANE mountains (60kHz) of Nagasaki Prefecture.
ElectroSuite.com - 125KHz RFID Module Kits. It is compatible with ID cards of 64 bit read-only EM4100, TK4100, and EM4102 series. It can be directly connected to Pin 2 of the computer serial port (COM). Antenna and the module has been adjusted to the best condition, with long reader distance. With CBB capacitors, it has anti-interference to temperature change.
ElectroSuite.com - PIC controlled 500W Modified Sine Wave Inverter. The PIC16F628A is programmed to produce a logic 5v signal for 5ms at pin 17 then 15ms off. Then the same at pin 18, 5ms on then 15ms off (4.17ms for 60Hz).
ElectroSuite.com - FM Band Receiving Converter. With just a short piece of wire connected to the converter and a scrap piece of coax cable going to the Stromberg Carlson 505H, stations came roaring in the first time I fired up the converter.
ElectroSuite.com – The 9 kHz to 6100 MHz Signal Generator APSIN6010HC is a low phase noise, extremely fast-switching RF signal generator with µ-Hz frequency resolution, and precisely leveled power range from -120 to +13 dBm.
ElectroSuite.com - Power Manager Remote Power Control Through LAN. PowerManager is a remote power management system that can be controlled through a web browser on a local area network (LAN). Devices plugged into PowerManager’s outlets can be turned on or off with the click of a button on a webpage. PowerManager runs on an ATMEGA644 microcontroller and an ENC28J60 Ethernet controller.
ElectroSuite.com - A8V W8EXI 6CL6 One Tube Transmitter. The operation of the 6CL6 transmitter is actually quite sophisticated, despite the simple appearance of the circuit. The heart of the circuit is the electron-coupled crystal oscillator.
ElectroSuite.com - 27500 MHz J Pole Antenna. 11 m Band J-Pole antenna centred at 27.500 MHz. The J-Pole antenna is a 0.75 wavelength (Lambda) long vertical antenna consisting of a main radiator 0.5 wavelength long fed by a 0.25 wavelength section folded back on itself (this section of the antenna does not radiate any significant power).
ElectroSuite.com – FM Stereo Transmitter. A method commonly used in (double side-band suppressed carrier) DSB-SC modulation to provide synchronisation between modulator and demodulator is to transmit a sinusoidal tone (pilot tone) whose frequency and phase are related to the carrier frequency.
ElectroSuite.com - Wireless Music Player Atmega644 Microcontroller. This project used an Atmega644 microcontroller clocked at 20MHz in each of the two functional modules for processing.
