Unemployment, poverty might have been the cause for this but still stealing others property is a serious crime. The only way to stop this is by alerting people themselves with proper security arrangements. Bus hijacking is what we heard commonly of, this is where the fear of crime lies.

No matter how far we try to escape from pest’s trap or we attempt to clean the surrounding around us, we get eventually bothered being followed everywhere from kitchen to every corners of our house. Different pest repeller circuits have been developed claiming to escort people through this problem. However, pest repeller circuits thus built are found to have low power output resulting poor effectiveness. And, this error gives no solution to our trouble. With this point as our main concern, we have presented a powerful pest repeller circuit that…

In order to measure the RMS voltage between two specific points, employing heavy and bulky electronic devices sounds unusual. And, therefore a small handy instrument can be used to avoid such situations where the voltage (i.e. RMS) between two points at any distance; large or small can be determined. For this reason, the instrument RF probe circuit has been proven of great help for home users as well as for communication equipment service/design labs. Description and Working of RF Probe Circuit RF probe circuit is just an instrument to measure, in…
