Hai guys..!!
*This post is not that much core type.It is for hobbyist persons which they can make at their home.It is the best instrument for sister and brother fighting for tv.In which it block the signal from remote of television.
*In which remote emits IR-Rays which are blocked by jammer/Blocker
*Circuit is self explanatory.555timer is wired as an astable multivibrator for a frequency of 38Mhz.
*The transistor act as a current source supplying roughly 25mA to the infra red LEDs.
*To increase the range of the circuit simply decrease the value of the 180ohm resister not less than 100ohm.
*This can be done trial and error until the remote no longer respond.
