IR Remote Control Jammer

schematic

Introduction

This circuit is a simple oscillator. It’s frequency is in the range 35 kHz – 60 kHz and it’ s adjustable.

Notes

  • D1 is infrared LED
  • Values of components are shown in schematic
  • All resistors are 0.25w and all capacitors are 16v
  • With RV1 you can adjust frequency
  • For best result circuit work with 9v battery
  • Pcb size is 2.5cm*3cm.

    is this functional and how it will work

  • Alguien sabe si el valor de R1 es 5.6ohms?
    Es que no lo comprendo en ese punto
    Luego el capacitor ceramico que indica C1 de 10/ que esta de pata 1 a pata 2, no se supone que tambien debe ser electrolitico,
    Lo ultimo y mas importante este ocilador dice trabajar en frecuencias de kiloherzios y entre los 35 a 60khz
    Mi pregunta es yo necesito uno para frecuencia de 60 pero HERTZIOS NO KILOHERZIOS gracias será que me sirva para inibidir o activar fototransistores trabajando a 60hz
