Hello,
I am designing a circuit which shall turn a device ON or OFF by blowing on it. I have a circuit in the form of a counter where in when a switch is pressed, the count is incremented, and i have the relay connected to the LSB of IC 4017. So each time i press a switch, the LSB turns from 0...
Yes i am also not sure whether it may work or not, i am just trying to put a simple idea into motion. so can you just suggest me ic's which are power amplifiers in range of 933-960 mhZ and 890- 915 MHz and band pass filter ics for the same frequency. i just want to try out on this simple idea...
Actually i am designing initially a monopole to receive signals from the roof then there has to be an amplifier and band pass filter attached with it, the amplified signal will be given to another monopole antenna that will re-radiate the signal in that small area having less signal. This setup...
i have taken over a project on RF repeater for mobile communication, which shall be useful in ares with less network coverage. the chain is
RF signal -> Duplexer -> SAW filter -> LNA -> PA
I need RF IC's for all the above. Can any one suggest which IC's shall suit the above approach?
i am using an SST89E516RD microcontroller. i have the code ready and just need to convert to hex file so as to load to my microcontroller. I am using Keil for generating the hex file. But keil does not have the same microcontroller in its part list. Can anyone suggest some other way or software...
I have uploaded the ckt diag as image and my circuit does have the rs232 comm on it. So can I prog directly using Flashmagic or there needs to be any steps ahead of it?

i am making a project on GSM based automation system. I am confused over the realay working as i have never worked on it before. Can anyone suggest which relay can be the best for operation of my project and also how i can interpret it physically.
