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.
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.

  • 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
