If you have a couple boards left over, I'd be happy take them off your hands Kerry. Just let me know.

Thanks for all the hard work Kerry.

^^You should put a set in the kgsshv!

using z-foils!

I just did a listening test and the first three boards all work great!

Volume switching is nice and quiet (electrically not physically). Lots of steps so there are no jumps either.

Yeah. That sums up how I feel too!

will drop this layout into the kgitsojc board when i finally

decide what switching relays to use.

Time for some fancy software.

this looks fantastic.

I am amazed at how fast you conducted this project.

No one beats team stax mafia for speed, quality and accuracy

I'm not going to argue with you on this point. But we could have a Kerry vs Lil' Knight play off, I don't mind running the book.

... Kerry thanks for all your efforts.

They are both part of the stax mafia.

Kevin, so will the digital attenuator be built into the kgitsojc board, or will it be separate and wired to the preamp? I originally thought it was going to be the later.

originally it was actually part of the board. but that was when it was single sided and much longer.

does not make sense to make the whole board 6 layers just for the attenuator, so its likely going

to end up as a board of boards.

I've got all of the board only orders shipped now

I've got a lot of testing to go still, so the assembly orders will take a bit longer.

Got my boards today, woohoo!

Big thanks to Kevin and Kerry for this.

What Fitz said, you guy rock!

My boards showed up today over here on the left coast.

Thanks again to the KG's for making this possible!

Got mine as well, thanks to both you and KG for these!

Looking forward to receiving mine. Also, for people like me who are complete noobs with the control interface, does anybody have any information on how this gizmo can be controlled? There was talk of software earlier, but I haven't seen any specific details......

Got mine last night. They look great. Thanks for all the hard work.

I've developed some software to use with the Arduino Uno board. I can post that in the next day or so with some simple instructions.

Kevin is working on an all-in-one device (display, process, interface) separately.

Awesome. Sounds like program over USB, hook up to the volume board/power/encoder, and away we go!

I take it these will be able to be used with a rotary pot? Thanks for the hard work Kerry and KG.

either a rotary encoder or a traditional pot can be used (or push buttons, or slider, or whatever you'd like), depending on the micro-controller platform and the code employed.

by the way, although i have not tested it yet, it should be compatible with the amb/linuxworks LCDuino thing.

you can tighten up on the timing because the relays on my board move at least twice as fast.

kerry's code is ultra simple and works great, additions would be necessary to go balanced if you actually

want the balance control function.

My new NMR install starts 8/22/2011, about 3 weeks early, so i'm not going to have much time for a while

on the ultra fancy 4Dsystems thing.

Bonus points for the first person to do a 3 knob volume control software. (.5db, 5 db, 50db) (or some such whacky stacked dial thing)
