I have made a bit of progress on my Google Play Music radio project lately, I got the PCBs back from the manufacturer and found several problems with them, all of which are things I would have noticed if I had checked the gerber files properly before I submitted them.
The most common problem was with KiCAD footprints being wrong, I had this happen where the MOSFETs used in the level conversion between the Pi and ATmega IC had the wrong pinout on the footprint, there were also footprints which did not have a bottom soldermask layer so the soldermask had to be removed using wet/dry paper.
I also did not receive the front panel board (instead got 20 of the faulty main boards), although looking back they would have only be faulty as well.
However I have been able to get the main board to work after several modifications;
As I did not have the front panel board I had to improvise one using strip board/prototyping board, this was relatively easy to do and is not that interesting so I will not go into it much, essentially I made a board to break out the power and LCD ribbon cables to the 16 pin header on the LCD and a board to hold the switches and rotary encoders.
I have also set the Python script to start on boot, originally I had planned for it to run in the background but this had an effect on audio quality, so ended up starting LXTerminal with the command needed to start the Python script.
Here are some images of the electronics so far, I did have a video explaining all of this but after watching it back and hearing how unmotivated and apathetic I sounded I decided to not bother uploading it:
Now all that is left is to design and build a nice enclosure for it, I was thinking of a 1930s retro style case (something like this), here are a few sketches of possible case designs (done by my dad who will likely be doing most of the enclosure fabrication as well):
More updated on this project to follow when I get round to making the enclosure, most likely this will be in around 8 weeks.
