WOW.... the digital camera trick is amazing!! so i tested my tranmitter.... and it seems to be working great.
So if i use the PT202C for receiving my 1kHz signal, should it be working too?
Im not sure of any international mail order sources, but i use a local company, **broken link removed**...
Sorry for asking , but what is meant by PLL?
Id prefer not to go and build another system, as i've already spent alot of time, and my money on all these components.
With my current set up, when the 1kHz signal is received, i measure 0 V at the PT202C. With lack of signal (Broken Beam), i...
Thanks for the quick reply....
I cant seem to get a hold of any other photo-transistors, besides the TSOP1736.
When you say i need a plain transistor, are you meaning i can use for example a BC547B? or a BC107?
Would you say my problem lies with the receiver unit alone?

Hey there Guys,
A while ago i managed to get my hands on a couple of old electronics magazines, "Electronics Africa", in it i found an on going article on how to build an infra red alarm system.(Picture attached)
Although it may be an old design, I have decided to try build...
