No, Rifaa.. China is the #1 seller of fine electronics components. Their lithium cells and LEDs can not be beat.But I thought Australia is one of the finest components sellers.
They are almost as reliable as a Zippo lighter.

What the ..............LMAOFWell, you would use less power when your house is burned to the ground.
The LEDs in a remote control are made for 1A pulses. The pulses have a very short duration and a remote control is never pulsing continuously anyway.i understand that 1000ma is sort of alot, so wouldnt this lower the life of the LED's?
A TV remote control modulates its IR beam at 36kHz, 38kHz, 40kHz or 56kHz.i think that all of the jammer circuits need to do is create pulses of IR light to interrupt the actual signal so i need high speed switching right? MOSFET maybe that will allow the 20,000 switches per second
Your LEDs might not survive a higher current. You also must reduce the pulse width.and a higher ma to my LED's
Examples of CMOS 555 part numbers that will work:thanks everyone, SgtWookie, so are the 555 in this schematic the normal ones, sorry i dont know what BJT is
It is missing an important supply bypass capacitor that will hold the supply voltage up when the transistor turns on the LEDs.Found this, and thought it would be helpful. Another circuit design.
And 3.9mA is rather small for a the LED's or a IR transmitter. You will have to be close to the TV. So close, you might as well put your hand over the receiver.The circuit as shown limits the LED current to only 3.9mA.
