Raspberry Pi player - USB Audio

[Tinker-RT]

The attached (fingers crossed) jpg shows a moOde player I built. 

Details:
Raspberry Pi 3B.
Waveshare 4.3inch IPS screen with DSI interface.
Extruded aluminium Project Box, 80×160×170mm.
Using USB Audio output to keep things simple. Connected to a Cambridge Audio CXA61 amp with USB input.
USB Stick has my CD files ripped to FLAC using dbpoweramp.

The push switch is power on/off. The extra circuitry is added to allow the power switch to shut down the Pi before turning off the 5V supply. This makes use of the gpio-poweroff and gpio-shutdown functions.

I was pleased to find that the Waveshare LCD works with moOde with no extra configuration required. Even down to the Backlight control from the moOde GUI. I disabled the touchscreen as I just want a "now playing" display.

A big thanks to the moOde team and also to the forum users - there is a lot of useful info on these boards!

One of my British acquaintances had a great expression for your effort. He'd say it was done "shipshape and Bristol fashion!"

Nice job!

Looks super cool :-)
What model Waveshare screen? Some users report tons of config.txt settings needed to get these panels working.

Thanks for the compliments. I'm an electronics engineer by day, so a "neat and tidy" approach tends to come naturally.
Most of the credit goes to Tim and the moOde team for the software. A pleasure to use!

The display is on waveshare.com as -
4.3inch Capacitive Touch Display for Raspberry Pi, DSI Interface, 800×480
SKU: 16239
Part Number: 4.3inch DSI LCD

I assumed that because it worked with no tweaks it had probably copied the interface spec from the official Raspberry Pi 7inch display. It also has the same 800x480 resolution. Perhaps i just got lucky...

Nice build :-)

Not a moOde-related question, but how did you make the cutout for the display? I always have to hide my ugly cuts with commercial molded bezels…if they aren’t available then something bogus like split tubing.

This is DIY in class awesome.

I marked out the rectangle on the panel, drilled a hole near a corner, and used a Jeweller's Saw to cut it out.

It takes a bit of practice, but with a fine blade you can get very accurate cuts and corners. Lots of "how-to" guides on Youtube.
I then wrapped a bit of fine sandpaper round the rectangle that I had cut out and used it as a straight edge to smooth off any rough parts.
I went over the cut edges with a black marker pen to cover the bare aluminium. This probably won't last - a bit of paint would be better.

It worked out better that I was expecting to be honest! The panel was only about 1.5mm thick, so was pretty easy to cut with a new saw blade.

Rats.

You did it the old-fashioned way, just as I was taught many decades ago when I was building my own amateur radio gear.

There's an old joke about a tourist standing in Times Square in New York City who asks a native New Yorker "how do I get to Carnegie Hall?" The New Yorker replies "practice, practice, practice. Guess I just never practiced enough.

Your result is terrific.

I'm a jeweller and having 30+ years daily sawing I know just how well you did getting those lines straight and true !
Trick is having a template, glued/taped on paper pattern, and cutting within the lines. Close enough to minimise further sanding/finishing but not so close as to overstep.
