This is an infrared transmitter circuit of the signal is small and using a power supply of 1. 5 V only. by the main electronics are the two LM3909 (oscillator IC LED Flasher) Normally, we tend to put it to work as a simple flashing light circuit. Use a source of low-power 1. 5 V, which is working now easier to use transistors. The high frequency is

very simple, just change the high frequency device only. C1 and R1 is less than the highest frequency.
