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?
-- Mart ====================
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?
