Going through a box of old stuff the other day I found the PCB of a microwave burglar alarm from a design in Wireless World from the 70s/80s.
Does anyone have a copy of this article?
Thanks
Mike
Is this the article from the July & August 1977 issues?
Keith
My notes show that as probably being "Construction of Doppler Radar to Detect Movement", M. W. Hosking, Wireless World, Vol 83, Number 1500, August 1977 pages 37 to 40.
I've added another WW article on the same subject - can't find the main one at the moment....
EDIT: ARGH! The curse of crossing posts! I think that the Keiths have it!
Thanks Keith and Nick,
The article I was after was in the July issue. I made the PCB and I still have a couple of the modules, thought I might get it working seeing as I have a suitable box too.
Thanks again,
Mike
