I’m changing things up for the πiFi Music Player.

• Before I started this project, I had never 3D printed before.
• I still haven’t made anything using a CNC machine.
• I’m not very good at fine wood working.
• I’ve never built speaker cabinets before.
• I’ve never built something using the GPIOs on the Raspberry Pi before.
• In fact, I’ve never actually finished making something using a Raspberry Pi before.

The way I intended to make the πiFi I would need to do most, if not all of these and it just makes it too large of a project. So I’ve scaled it back. At it’s core it is still going to work the same way but instead of having a built in power amp and connecting it to custom built passive speakers I’m going to make a device that gives line level audio out and connect it to a pair of powered speakers that Iris already have but rarely use.

At first I decided to do this using a Raspberry Pi Zero and a JustBook DAC Zero and that was what I sat down to work on tonight. Unfortunately I realised that the Pi Camera Module needs a different cable to be compatible with the Zero and none of my usual suppliers for these kinds of things have that cable in stock. As I was thinking about whether to keep working on other parts of it hit me, why not use the Pi 3 that I used before but without the power amplifier hat? It has a line out built in and works with the camera cable that I have?

So tonight I’ve been working on the first iteration of a simple 3D printed base plate to mount the Pi on, with place to stick the QR codes on in front of it and a mount for the camera. So far the camera mount isn’t finished but I do have a prototype sketch that should work for mounting the Pi and the QR codes. I’ll try to get it printed tomorrow.
