hello

i was wandering can i use simple multivibrator circuit to generate 38khz signal to use as a IR transmitter for TSOP1738?

i did some readings and calculations and came up with resistor and transistor values that gives 38khz.

but since i don't have a oscilloscope i don't know whether this circuit will work.

and most importantly all 38khz IR transmitter circuits on internet are based on NE555.i wonder why nobody use a multivibrator?

calculations are based on article

Multivibrator - Wikipedia, the free encyclopedia

any help would be great

thanks

here is my circuit diagram
