I need RF soundless frequency emitter. Instead of audio it would just emit downloaded music file frequencies.. What I mean is if playing any music file it would just play out frequencies. Sort of radio emitting antenna. The purpose is instead of a sound (perceived by ears and also by the whole body as a vibrations) be exposed to just vibrations. It needs to have internal memory for loading musi...

Hi, Very urgent need power electronics and power systems based expert today The deadline is 10th dec ,so apply asap

In most houses, water is first stored in an underground tank(Borewell in this case) and from there it is pumped up to the overhead tank (OHT) located on the roof. People generally switch on the pump when their taps go dry and switch off the pump when the overhead tank starts overflowing. This results in the unnecessary wastage and sometimes non-availability of water in the case of emergency. This...
