I've managed to get 3 out of 4 B22 boards up and running, but the last one is giving me trouble. I installed LED+ backwards, but it won't light up even after I fixed it. Pics and measurements here: AMB Laboratories DIY Audio • View topic - no LED+ on B22 board Jeff

Finally got my S22 and B22 boards powered up (only one of each in pics). All 4 S22s tested fine. One B22 is all setup, getting too late to do the rest. I could only get the DC offset down to 7-8mV though. Barely even got hot enough to tell it was on (set at 160mA). Jeff

If you were to stack 4 of these (2 Delta-1s & 2 Delta-2s) what would be the height? Would there be any reason you would not recommend stacking 4 of these? (Assuming you do all the inital config and tweaking before they are stacked.)

Ahh, I see. Seems easy enough to do. Can't wait until you guys start selling all this LCDuino stuff

Cool Another very nice product from the AMB/Linuxworks team. However, I was disappointed to see the last sentence... What would be the best way to adapt/incorpate speaker output switching if I was using this module?

That's a great idea. I picked up some cheap, thin Aluminum to use as some temp panels, so maybe I'll give it a try.

That's cool, I'll be using them if I ever finish my B22. It would be nice if there was some way you could test the layout though. I'm afraid of spending over $400 on panels, then having something not fit, or not be positioned correctly. I shudder at the thought of taking a file, hacksaw or my...

I'm sure this was mentioned somewhere before, but I can't seem to find it. What is the depth of the LCDuino? How much space behind the front panel does it require? Jeff

Very nice work! What are the dimensions of the board?

Cool Eagerly awaiting further developments...

Well, I realized that I could just use the USB connection for sound, so I can at least listen to music now. Would there be any advantage to using the analog inputs instead of USB? I would have to hack together a cable unless anyone knows where to get a mini to dual 1/4" cable.

Is it possible to use the SPIDF out from my soundcard to connect the 0404? I thought I read somewhere that it only worked in certain circumstances. If not, do I use a mini to dual TS cable?
