I used to record my 'inventions' in a diary - until Dinesh one day got hold of it and laughed at me. I believe it was regarding one of my more inane imaginations entitled 'Blinker'. A simple rotating can with strips of insulating tape demarcating the live areas. This was to make a filament lamp blink. I believe the same could have then been achieved with a circuit that would've fitted on the head of a pin. But I did not know better.
But hey!! It was MY invention and you laughed at me!!!
Anyways, from the ashes rises a phoenix etc. etc.
I have bigger and better inventions now. But alas no diary for you to peruse and laugh at!!!
Just you wait Mr. Higgins - Just you wait!!!!
