I was thinking about building a project from an old copy of Television magazine (March 1999) & (April 1999) since i have most of the components needed. The project in question is an esr meter design by Alan Willcox..UK.
Recently whilst browsing the net i came across a circuit from the late Poptronics magazine US. for another esr design but not the full article only the cct with errors being pointed out regarding incorrect component values a red circle drawn around the culprits and the correct values being given. Can anyone who built this Poptronics design comment on it's performance in use as i would like to build this tester also if i can manage to get a copy of the article dated (June 2001). if someone has a scan of this article/circuit i would be gratefull to have it,
The UK version uses two 9v batteries in series, whilst the US version uses only one 9v battery which appeals to me,
