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
