@clarke: I'm shooting for late October, but I'll follow-up with you via email as soon as I can lock something down.

I'd better start cleaning up my office!

Cool beans -- you'll have to come and visit me at my office and then we could go out for lunch -- when do you think you might be coming over here?

I didn't realize (but should have known) that you already had a piece weathering naturally for comparison.  I'm interested to see this process and I'll bet that book mentioned earlier will be a big help.

I'd love to see them in person, but I actually might be making my way to Huntsville, AL before the next ESC.  Which might save you from having to explain how you aged the brass to the TSA. :)

Also I'm not certain I'll be able to make it to ESC again this year but I'm hopeful!

Oh please no!  If that comes to the house and my wife opens it I think you'll find that I will have aged more impressively than the brass.

Perhaps I should take a picture of myself as a control.  :)

@Clarke: I'd love to see a couple of brass pieces for comparison.

I'm trying different techniques and keeping all of the results -- I have a piece on the roof of my office building as we speak -- it's been up there for a week now in the sun & rain with a dash of polution -- I need to go up there ant photograph it -- I plan on doing that week by week so we can see how it evolves -- bujt it's drizzling at the moment and the ladder on the side of the building is dangerous enough as it is .. so I'll wait a bit :-)

If you are really interested, I could bring out all of my test pieces to ESC Silicon Valley next year...

@Clarke: Next time I think we could really use a picture of you working with the cans of poo.

I have a can in the post to you so you don;t have to imagine what it's like LOL

Next time I think we could really use a picture of you working with the cans of poo.  You know, just to set the scene. ;)

I have absolutely no experience with aging metals but I'd love to see a couple of brass pieces for comparison.  I'm thinking an untarnished brass piece and a naturally aged brass piece (weathered outside) alongside the new brass pieces as you try new methods.

As always, looking forward to seeing the next step!

@jchrisj: I just found a book in a local bookstore called: "Patina: 300+ coloration effects for Jewlers and Metalsmiths" by Matthew Runfola.

OMG! Thank you, thank you, thank you. I just ordered a copy -- now I must perform my happy dance!

Patina book

I just found a book in a local bookstore called:

"Patina: 300+ coloration effects for Jewlers and Metalsmiths" by Matthew Runfola.

It looks like it just came out in February of this year. I found it on the shelf at a Books-A-Million but it is available on Amazon.

It is organized by metal (Brass, copper, silver, etc.) and contains page after page of pictures of metal samples and a description of the treatment that was used to get the effect you see.

The pictures can't give you as accurate a look at the effects as having a physical sample but you could find a few that you like and test them yourself.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
