Aha! I get the gold star for last week's puzzle picture as no one managed to identify it.
My thanks to all those who attempted a guess.
It was a very close view of the head of a match.
And now for the new close up to identify:
Clue: It could heat up at the same time as last week's object.
No prizes. Just a bit of fun.
I really must catch up on some other blogs today. I spent a lot of time over the weekend trying to make some sense of the C++ programming language. It's many years since I use Sinclair Basic, then BBC Basic and finally Agfa Basic (Atari ST) but now I want to be able to have a play with the modern generation of programmable microprocessors as used in the Arduino kits. I want to build some more versatile methods of controlling the camera for nature photography so I think I will be needing a new bottle of aspirin to cure the headaches when I start banging my head on the wall!
