First build of Afterglow by Slingshot Assembly

I've been working on a PCB for a small loudspeaker project called Amey. I showed a rendering of the bare PCB a few weeks before I sent the design to Slingshot Assembly in Denver. I got the assembled PCBs today:

They installed the snap-in standoffs at each corner on the component side, which helps to protect the other components during shipping. That was a nice touch.

Update -- oops, the ADC doesn't have a clock

I made a showstopper mistake with the rev A boards -- I didn't provide a clock to the I2S ADC. The PCM1802 ADC from TI can be an I2S master, but it has no way of generating its own timebase. The fix is to figure out how to get a clock to the PCM1802. I made a second PCB to hold the DSC60xx 16.9344 MHz oscillator and its bypass capacitor. You can see the second PCB below.

Afterglow mod

I carefully wired up the little PCB, and now I see the correct clocks:
