Hello, first post, possibly the only one... I am writing some English teaching materials for technicians and I have to do some classes on electronics which I don’t know the first thing about. Done some research, put some stuff together, BUT...

...I really need a listening exercise, where someone explains to me a basic (but not TOO basic) circuit diagram. I’ve trawled the web, but all I can find is far too simple (one lamp, one battery, one switch) or far too complex (for electricians, basically). I need a diagram of something (lord knows what) which is really simple, but still contains a decent selection of transistors, diodes, inductors, capacitors, etc (not all those things, but eight or so elements) and then an explanation of how it works.

Does this make sense? Can anyone help?
 


Thanks! I think that radio transmitter is perfect...

Almost... here’s my big request. Could you - someone - anyone - write out a description of the circuit diagram (on the first page of the radio transmitter page) as if narrating it to someone who had never seen it before who had to copy it down?
 

Thanks for the suggestion, but its beyond me. The diagrams are the right level - but I need a full description (narration) of the diagram itself, not how to make the circuit... as if an electrician is narrating a diagram over the phone to someone who has never drawn one... like I say, its a lot to ask, but hope springs... :-D
 

I think the idea of explaining how to draw a circuit diagram over the telephone to someone who has never drawn a circuit diagram and therefore won't know any of the symbols necessary sounds like an impossible task, unless I am missing the point of this exercise (which is ...?). I assumed the purpose of the exercise was to explain the function of a circuit not the physical drawing of it.

Sorry, haven’t explained myself well enough. They know the symbols. The purpose of the exercise is to practice listening and writing (its for speakers of second languages - Russian electricians). So Student A explains a circuit (not necessarily over the phone - that’s just to emphasise it is a speech exercise) and Student B writes it down, then Student B checks what they have drawn against Student A’s original to see if he has heard correctly. So I need a diagram, and then a narration of the diagram, or a description of a circuit that someone could draw the same diagram from. The narration can include instructions like ‘okay, and then a resistor is attached to a bulb, and that’s connected to a diode,’ etc... just as long as someone hearing it can draw an accurate circuit diagram from it.
