Here's my scratchbuild of the security cameras seen all over the place in Blakes 7. The camera is made from plasticard. I put a flashing red led and an led torch into it just for the fun of it! The bracket is built onto a flagpole bracket.
My ten-year-old self just started crying with admiration! I watched Blake's Seven every week as a kid and can remember practically nothing about it except that Villa was my favourite, I was gutted when they all died, and it was a great show that probably looks cheesy now.
