July 30, 201114 yr 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.
July 31, 201114 yr 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.
August 1, 201114 yr Author sweet will drop this layout into the kgitsojc board when i finally decide what switching relays to use. Time for some fancy software.
August 2, 201114 yr No one beats team stax mafia for speed, quality and accuracy NO ONE 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.
August 5, 201114 yr sweet will drop this layout into the kgitsojc board when i finally decide what switching relays to use. 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.
August 7, 201114 yr Author 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.
August 13, 201114 yr 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. Edited August 13, 201114 yr by Kerry
August 16, 201114 yr Got my boards today, woohoo! Big thanks to Kevin and Kerry for this. What Fitz said, you guy rock!
August 16, 201114 yr My boards showed up today over here on the left coast. Thanks again to the KG's for making this possible!
August 16, 201114 yr 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......
August 16, 201114 yr 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.
August 16, 201114 yr 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. Awesome. Sounds like program over USB, hook up to the volume board/power/encoder, and away we go!
August 16, 201114 yr I take it these will be able to be used with a rotary pot? Thanks for the hard work Kerry and KG.
August 16, 201114 yr 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. Edited August 16, 201114 yr by luvdunhill
August 16, 201114 yr Author 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)
