  • I've got my controller boards working pretty well now with the digital attenuators.  I like the larger one because it has a really nice feel as you turn the volume knob (...yes I see it ). I went

  • Here's the code.  Just rename the PDF to Zip and expand it into a folder under your .../Documents/Arduino directory. The code works well now, though there are a few things I'd like to keep workin

  • Just wanted to offer a quick update on this...... I couldn't get the "all in one" code from @Kerry to work perfectly with my setup; it always opened up the relays to full volume on power-up, and I cou

Kerry, can I reduce my order to 2 assembled instead of 4 assembled?

Sorry, but money is getting too tight to mention :-(

Payment sent! Sorry for the delay, but I've been busy with conferences, holidays, and poor internet access......

Just wanted to give everyone an update. The boards were sent and confirmed on Monday to Imagineering. We will be getting a first article of 5 boards (one panel) in about two weeks.

I'll build a board to make sure everything is good and then go ahead with the rest of the boards (two weeks from when we confirm the boards). I'm doing 150 to have a few extra.

Once that is complete and they've shipped the boards that will not be assembled, I can start getting them sent out to everyone.

Next step for the assembled boards will be to send the board I hand assembled to Imagineering and have them do one board. We'll get it back and test it, then run the rest of the assembly order.

I regret missing this GB, if an opportunity should arise and 2 bare boards become available please consider me as a reserve.

Kerry you do amazing work for the forum!

I do have some extra boards and can still do some additional assembled boards as well.

Great News!!!

We got the first board in. I'm waiting on parts, which will arrive this week, and will build this before they run the rest of the order.

Here's some pics:

Can't wait to test this :)

Looking good! If you need a platform to test the software, get a arduino uno, they are super cheap.

Looks great! Thanks again for the under taking Kerry

I've got an Arduino Uno board and Kevin has the all-in-one display that he's posted here.

I was also looking at the Netduino as another possibility (I can program it with .NET).

Got parts :D

EDIT: I'm going to build the board now so we can start testing.

There's more than 560 relays in that pink bag, isn't there?

The white box on top are the relays - 584 of them :D

The pink bag contains the sockets for the PCF8574s.

Once I test the board, it all goes off to manufacturing :)

I was able to build the board and it's ready for testing :D

Sweet! Looking forward to a functional outcome.

Looks great! What resistors did you end up choosing??
