I've just received the following email asking about a 9 year old thread.
==================== Hello.
Found one old thread -
Do You have "the Random ON/OFF Timer Circuit", if yes, can You please send it to me?

I would be interested in a copy of this circuit diagram as well.
Thanks,

What does Q4 do?
If you found it, where is the link for the schematic please?

Quoted from- Terry, East Grinstead, UK :
I've found my own contribution to that thread and uploaded it here
So, if John is around or anyone else has the circuit or a link to it, could you post please?
In MY circuit, if I recall correctly (it's been some years since I did any serious practical electronics), Q4 is part of a fairly standard
2-transistor Schmitt.Robert W, like Mart and me, was asking for a link to John Fields' circuit. So I'm still hoping one of the regulars can point him in the right direction please. I'd like to see it again too. Does JF still contribute here?

-- Yeah, but S/N is pretty low here, so I mostly just gloss over all the junk until something juicy comes along.
Many thanks, John. I'll email a copy to Mart who was apparently having trouble joining the newsgroup.
Do you know whether the a.b.s.e archive was pruned around 2008?

-- Sorry, I don't have a clue...
