Hi Nigel,

I agree about the Peak testers, I do have a Peak DCA55 that my wife bought me last Xmas and its excellent, but at the moment its the old time or money equation! No money but spare time!

I do live fairly close to Buxton but unless they do a very favourable discout for living near them I can't afford one yet

Saying that, I also live close to you, and maybe you don't want your "inferior home made ESR meter" hehehe

You live considerably closer to me!

Funnily enough, I do have one partially built at home, when I built my original one at work I started building one for myself as well - but never finished it. But knowing where it might be is a differeent matter?.

Hi Nigel,

Well if you do happen to come across it give me a shout!

It would be nice to meet one of the members in person, but will I recognise you without your martial arts gear on?

Seriously though, slipping over to your neck of the woods isn't a problem mate.

hi Al,
Just checked my stock I have a brand new 100uA FSD analog meter, scaled 0 to 3 and 0 to 10.
Its a freestanding meter in its own case.

You have my email, send me your address if you want it, its yours free gratis.

Excuse the poor image, I had all my decent camera kit stolen in Jo'burg 5 years ago, replaced it with a el-cheapo.

That would be great Eric, I will email you the details and will gladly reimburse you any costs, if you have a PayPal account it I can send it immediately.

Anyway I am going to email you with my details now.

Thanks again Eric....................Al

Hi again Eric,

Just to let you know that the email you will get is from my wifes email address!

For some unknown reason my own emails have stopped working, which is a common occurance with this provider! Though how mine can be broken and hers still works fine is always a baffler!

Did you steal it from school Eric?

Nice meter, from RS Components, which of course they weren't called when you (or me) were at school.

hi,
I have had that meter IIRC, since about 1970, never used it, still in its original box.!
Sadly a long time after my school days which ended in 1946.....

As I posted the other day, the first RS catalog I saw, was A6 size, about a dozen pages. RF coils and solid dielectric tuning caps.

I did have some pre war Camm's comics, gave them to a guy who lectures on classical electronics.

EDIT: 1948 >> 1946 !

In 1970 it was still Radiospares, I think it was mid/late 70's when they changed to RS.

I left in 1971, I'm not 'quite' as experienced as you

I used to have loads of old magazines, I threw them all away a few years back now.

Perhaps you might like the following scan I just did, it shows how the logo used to be - and is an item I've still got 'in stock' at work.

I'm sure you will be able to convert the price on it!

Hi Eric,

Thanks again Eric, I can't wait to get building the new meter!

Hello again Eric,

Thanks to your generosity I am looking to build a different meter than the duff one I have been fiddling with for the last month!

Just one question before I start.

Which of the following links that Ron posted do you think would be best or more suitable/servicable and accurate.

http://www.qsl.net/iz7ath/web/02_bre..._esr/index.htm

http://www.ludens.cl/Electron/esr/esr.html

You have a much greater knowledge of circuitry than I do and I have no doubt that you will tell at a glance which would be the better choice!

I have the parts for either with the exception of the transformer (which can be made without too much trouble I think) so I can make either one.

Thanks again Eric and everyone else who has contributed to my long journey to a working ESR meter.

hi Al,
Looking thru two web sites, I would go for the one in this picture.

It seems better documented than the other circuit, also a number of other people have built it and it works.
