    Hi, I'm a complete novice in electronics(didn't absorb much from our professor, he's not that good at teaching:D).
    We have a project, research then present a simulation in class on Wednesday about a device with two or more transistors, after "googleling", I found a simple(I think) device from this page.
    I tried to make the simulation in Multisim and I'm have errors, please help me get it to work. Anyone explain what's the story in this device?
    Any help is appreciated, thanks in advance!

    Didn't look at yours, but it's a simple oscillator, around 38 kHz. The reciever can't pick up the pulses from remotes, they only see a steady carrier...
