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 [...]
With the circuit shown here you can create high frequency electromagnetic waves with very high output power. Possible applications are experiments with wireless power transmission, RFID Transponder, tesla coils and the like. Dependent on the coil, capacitor and cooling of the transistors output power in the range of 20W and more can be obtained. At [...]
Mini FM Received Circuit TDA7021T chip radio receiver ambit is for carriageable radios, stereo as able-bodied as mono, area a minimum of ambit is important in agreement of baby ambit and low cost. It is absolutely accordant for applications application the low-voltage micro affability arrangement (MTS). The IC has a abundance bound bend (FLL) arrangement [...]
Rangkaian Wireless Microphone Sederhana Rangkaian Wireless Microphone Sederhana Parts list:
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 [...]
Media Center PCs Remote Control Infrared Receiver Circuit The ambit consists of accustomed apparatus (except of ATtiny13 in some cases). The IC1 is an bittersweet receiver at 30 kHz. The T2 makes the about-face On/Off of Media Center back it gets a High akin by IC2. The K2 is affiliated at the “power switch” adapter [...]
UV916-tuner Radio Receiver 45-860MHz To build a Spectrum analyzer I needed a tuner. I also needed to learn how to control the tuner. In some old broken TV I found the tuner UV916. It is a common used tuner. The tuner is PLL synthesized controlled and the frequency can be set from 80-900MHz. The tuner [...]
