Well, its been a while and its time for an update. Thanks to a lot of help from this forum, especially Corpius, and the Hifiduino blog (GLT?) I've successfully added display and remote control features to my B-III. For the most part I followed the Hifiduino model using Arduino and an Apple Remote, and Corpius's Buffalo shield made for much tidier connections. His help was invaluable in working out the kinks in the code.
Here you can see the Arduino and CE-Designs shield (top center). Mounting in the front might have been more ideal if I had planned this from the beginning, but it still went in pretty clean and easy.
Below you can see the LCD panel mounted to the front. I started off with a negative backlight LCD and just this week upgraded to a Noritake VFD, which required a few changes. Mainly, I had to discretely supply power to the display since it draws something like 400mA, far more than Arduino can handle. I had to juggle things a bit to avoid adding more power supplies, so at the moment I've got 1/2 the LCDPS supplying the Buffalo, 1/2 supplying the Arduino and display and a tiny AMB labs 5v supply doing the Toslink. So far its working very well. LCDPS is certainly a nicer PS than Arduino requires, but this is what happens when a project evolves slowly over time. Since the VFD requires no BL (backlight connection) and is getting power straight from the supply, I'm really only using 2 pins from the Arduino + Shield to the display.
I found it pretty much impossible to get a realistic photo of the VFD, but here is something, for what its worth. Suffice to say I found it to be a huge improvement over the LCD. That said, its really bright, and as others have suggested I think it probably belongs behind some kind of smoked plexi.
So all in all, its still hideous, but I'm holding off on a nice panel until I'm satisfied with the evolution. Honestly I like having ugly gear for a while, and its nice having a cheap stock front panel I can cut up to try things like this out.
Up next is the USB, I was about ready to go with an Amanero but its sounding like Russ is actually getting close to releasing, so I think I'll hold out a little longer. I guess when I do that, I'll add a 2nd USB port on the back for Arduino software updates.
Anyway, cheers to Corpius, GLT and everyone else with way more complex projects, I've stolen from you all and its been a lot of fun. BTW, its sounding killer and the functionality of controlling all the Sabre32 setting from my couch with a slick apple remote is pretty unbeatable.
