Hey all, 

This the schematic and board layout for part of my audio cube, all I currently get with the CardInfo sketch is 

Initializing SD card...initialization failed. Things to check:
* is a card is inserted?
* Is your wiring correct?
* did you change the chipSelect pin to match your shield or module?

I have removed the breakout pins from the schematic to make the who mess easier to read. I realise it is a bit horrible looking.

I am pretty sure, or at least as sure as I can be, that it is all wired up correctly. Can anyone confirm?

Have you put a meter on vdd and verified you have power? I can't tell from your schematic where the SD card get it's power from. Maybe that part got cut off? Also, maybe write a small sketch to toggle on command each of the pins that go through the level shifter to make sure that part works, you can verify with a meter? How do you do 2 instantiations of SPI ports, you don't seem to be sharing SCLK, MOSI & MISO with the SD card?

It looks great but it won't read from the sd card, going to need help from the community on this one.

+Jeff Crawford Yeah, they milled it for me. I came out really well. They are a bit hard to solder without a mask though so it looks a bit messy.

It is a little hard to see on your diagram. Could you add net labels to make it a bit easier to see the MISO, MOSI, CLK and 3V3 and GND connections at the logic level converter.

Which logic level converter device are you using?  It wasn't on the diagram. 

Electrically the connections look correct as far as I can tell.  Assuming there are no power supply issues and the circuit has been correctly supplied with +5V and +3V3 at the correct pins and 0V then the circuit should work.  Check that the correct voltages are on the correct pins...after that it's time to check the code.

If I throw up a schematic and board layout does anyone fancy helping me troubleshoot reading the sd card? It is essentially an uno with an adxl345 and a micro sd card socket. Level shifting 'should' be taken care of...

+Bob Seddigh Thanks mate, it would be great to get a straight replacement, I will shop around and see what things look like in the datasheets this time.

Looking forward to more videos. It's cool that you are all working together on the project.

+Eric William  I have been playing with the esp8266. Do you fancy making something together? I have an idea but it is a little off the wall.
