RC5 is not suitable as a barrier to race out to whoever is the winner. Two or more RC5 channel interfere with each other and the protocol itself also takes time for the transfer. If more than one car with RC5 transmitter arrive close together, it can well be the first and the second triggers [...]
88-108 MHz FM Beacon Broadcast Transmitter Circuit This circuit will transmit a continuous audio tone on the FM broadcast band (88-108 MHz) which could used for remote control or security purposes. Circuit draws about 30 mA from a 6-9 volt battery and can be received to about 100 yards. A 555 timer is used to [...]
Rangkaian Wireless Microphone Sederhana Rangkaian Wireless Microphone Sederhana Parts list:
Laser based projects acclimated to be expensive, until the development of solid accompaniment lasers. This activity is advised for the access akin laser experimenter. The ambit allows any two computers with consecutive (RS-232) advice adequacy to acquaint over 200 meters application a laser beam. A low amount transmitter alone ambit is additionally presented actuality for [...]
AT90S2323 Microcontroller 418MHz RF Transmitter 2 Channel The transmitter is constituted by AT90S2323 microcontroller and TLP434 RF transmitter module at 418MHz. I have designe the transmitter for more battery economy and safe transmition of the data. * The battery economy is made it by the use of powerdown mode of AVR. In this case the [...]
The circuit of AM transmitter is designed to transmit (amplitude modulated) DSB (double side band) signals. A modulated AM signal consists of a carrier and two symetrically spaced side bands. The two side bands have the same amplitude and carry the same information. In fact, the carrier itself coveys or carries no information. In a [...]
Micro Power AM Broadcast Transmitter In this circuit, a 74HC14 hex Schmitt trigger inverter is used as a square wave oscillator to drive a small signal transistor in a class C amplifier configuration. The oscillator frequency can be either fixed by a crystal or made adjustable (VFO) with a capacitor/resistor combination. A 100pF capacitor is [...]
