See this is the awnser I was looking for THANK YOU +rep but how do i do this ?

This would require a data aquisition card, an instrumentational amplifier attached to a very sensitive inductor, and amplified so that the minute changes in electrical forces in the air generate a voltage of between 0 and 5V (a bit of knowledge of instrumentation would be required). A DAQ (data aquisition card) will have a built-in analog to digital converter, so if you just wire up this small amplified 'static sensor' to one of its inputs, it will store the value (from input 0-5V being output 0-4096) in a register. How you access this register depends on the DAQ setup, which can be an entire course on its own.

This is a pretty complex method to do a very simple task (generating a random number), and while it is possible it is pretty impractical. If you are new to programming, I would sugguest spending your time on other things.

this is retarded.

you won't get a reading from the free electrons in the air. you'll get a reading from the noise of the instrumentation pathway, which is deterministic.

now, i'm glad you're the hero of this 13-year-old's fantastical musings, but really, you ought to take your own advice about "spending your time on other things."

Ok so all I need now is the kit which probably will be in the physics/electronics/design and technology classrooms I'll ask my teacher Mr Stephenson if I can hope he says yes ! otherwise me and my father will build it at home.

You're right, it's major overkill. But it's the only answer in this thread remotely close to what the OP asked.

@OP: If you really want to use a microphone (and you use windows) click here. Then just use the x-first bytes from the data you got and it will be another way to get a semi-random-number.

My personal favorite for a random number is the Mersenne twister. (Lot's of free implementations available)
