New DIY Project for measuring noise : 10Hz..100kHz LNA // 1MHz RMS-DC converter

[carpin]

From the Wiki

The price would be 25€ for each PCB.
The price will include international shipping to EU,Canada and USA.
(Others country, please ask my by PM)

I will order professional PCB only if at least 10 PCB are ordered.

Wiki Here

Hello all,

Thanks to carpin for his generous wiki link that i had omit.

I'm very happy that they have many interested DIYers to build this project.
Now, the minimum qty of ten PCB is reached.
I will close the PCB pre-order at the end of this month, December is already so filled !

I just have publish new documents about the ERMSDCV2 project on the wiki page. (follow the carpin link )
As soon as i have a little more of time, i give you news.

Regards.

Hi:
Being fairly new here I don't yet know how to order except by posting to the list. I need two, plus any other parts you care to make available. Delivery in the New Year is fine. PayPal works ? ?

Pearl,
Out of my experience Frex host some of the best buys around. He will send you an email request when he is ready, and yes, you can send the payment over the paypal. Last time Frex emailed the full proper documentation regarding the project, what makes life much easier. I am talking here for Frex and I am sure he will let you know the details, but I figure out to share the exceptional experience in dealing with Frex.

Yes, please.

Don't know if you've finished the PCB -- back to back 220u/35V Elna "Silk" are what I use in my LNA -- I also found some caps in an an HP Measurement Amplifier which measured very low leakage via the Jim Williams 24 hour method but I could never get his circuit to work correctly.

Boonton protects the input of their 1120 distortion analyzer with 1/16th A fuses. I know, as I've had to replace them!

Jim Williams of LT ? ? and what is that circuit ?
