    Building the Tivoli Squeezebox Radio

    Usually I write more in the "Software" section but today I want to write primarily about hardware since I've built a nice and stylish DIY radio.

    Itís a Squeezebox built from a Tivoli Audio alarm speaker, and for the impatient ones among you, here are the key features and a picture:



    • Tivoli Speaker and case using the original speaker and 3W output;
    • WiFi;
    • runs on battery for a whole day (more than 12h);
    • rotary and push controller for volume and play/pause;
    • separate alarm clock;
    • fully Squeezebox compatible player using a Raspberry Pi zero and SqueezeLite;
    • very simple and power-efficient 5V design.


    And since Coolio and I do software in the first place, the whole project has its own software as well, in this case our open-sourced solution to power the volume and play/pause control. Itís quite cool, too , you can find it on GitHub at https://github.com/coolio107/SqueezeButtonPi-Daemon
    If you want to discuss it in this forum, there's a separate thread for that: http://forums.slimdevices.com/showth...oders-on-a-RPi

    I have to admit I wasn't too happy with the encoder and the knob but I didn't find anything better (encoder) or better fitting (knob).

    The encoder is a pretty standard rotary encoder as you can find them on Amazon, Conrad etc. max2play also sell one of these on their web site. I bought several from several sources (they come at around $2.50) and they were all the same.
    It's a bit shaky and it has very noticeable stepping and it only has 24 steps per rotation which is why for my setup I used both flanks of the signal effectively doubling the volume increase per rotation but also reducing accuracy. For a more hifi-like project (I'm planning one for next year or so, think Transporter replacement) I'm definitely going to look for a better encoder but they are really hard to find and they are expensive. Like 50-100$ or so if you only buy one. There doesn't seem to be a mid-price segment.

    The knob is this one:
    https://www.conrad.de/de/drehknopf-a...st-717569.html

    I wasn't 100% happy with it either. It's essentially a plastic knob with an aluminum inner ring for mounting and it wasn't sitting tight on this ring, I added some rubber to the fitting of the aluminum ring to make it sit tight.
    But it was what looked best with the radio.

    I found a really nice knob, full aluminum and all, but it was too big, that really didn't look good with the Tivoli Radio so I'm maybe going to use it for the next project. I still have it, it's this one:

    Hi Pippin

    Thanks for this, it is really interesting.
    I have also looked into something similar, and was thinking that maybe something like this would be idea.

    As far as I understand it is something like the wheel on the Duet controller and also have four different directions/buttons: http://www.elma.com/en/products/rota...-wheel-detail/

    Another option also with four directions/buttons:

    http://www.alps.com/prod/info/E/HTML...tch_list1.html

    These devices might make it easier to manipulate a system using a screen based navigation like Jivelite or have presets with radio stations .

    I bought three or four from different sources and they all turned out to be the same

    What I like about this one a bit more is that it has a metal shaft but I don't know whether that actually makes a difference

    Does it rotate more than 360 ? Can it do several turns or spin endlessly, can you make up for the shakiness by having several turns represent 100% volume ? Several products with encoders I've seen does that .

    Building the Tivoli Squeezebox Radio

    IR is definitely not for me. And for device to be carried around that would be another device you have to take with you.

    I've tried to place the half a dozen or so Squeezebox IR remotes I have around my place but still neither me nor my better half are ever using them

    I thought it was for your mother.

    Does she carry her's around?

    Understandable - best for static devices - or at least for devices then tend to stay in one place.

    Yes. And she's actually even less into IR remotes than me.

    Yes. That was the idea. She takes it out on the balcony and into the garden.
    That's why the WiFi performance was so important, too.

    She usually has her iPad with her for reading so can use that to switch channels (she mostly listens to radio) but most of the time it's really just turning it on/off or changing the volume.

    One of the reasons she wanted it was that while she mostly listens to radio not all of her favorite stations are still available through FM or cable so when she realized she can play them again through the stereo when she got her first Squeezebox device she wanted an "everywhere" radio, too.

    I could have bought a used Logitech Radio on eBay but that really doesn't fit her furnishing style
