    Finished the RPI streamer for another friend.
    This one has an internal power supply and is fitted with an SPDIF hat. Initially I planned on using the Hifiberry Digi+ but it doesn't work well with the display. The PCB sits over the display connecter and so obstructing the display cable. The Hifiberry "clone" does not have that issue. The clone also has a better supply filtering on board.
    The streamer also has a 12 volts trigger input so that it is automatically powered on when the preamp is switched on.
    Below are some pictures of the streamer:

    Thanks!
    I didn't use the Hifiberry beacsue it doesn't alow the display connecter to be fitted on the RPI.
    I used the PiFi HIFI DiGi+ instead. It is cheaper and I find it better constructed than the Hifiberry Digi+.

    Berlin BoomBox with Pi 3 and PCP 3.2

    I have to say, I love this one. Ok it doesn't sound so great but it is, IMHO, the very definition of cheap and cheerful.

    Integration is very basic:
    - The original power cable was extended with a Y cable powering both the amp and the Pi. Ground hum is tolerable, YMMV
    - The amp has auto shut-off, that's a nice thought when powering the box with batteries but it is a bit adverse in my case. I soldered a cable to a reset pad on the amp board and flip-flop a gpio output pin to wake the amp when needed. Squeezelite does that on power up, for example.
    - The Pi 3 is sort of a tight fit in there. I did away with the bottom of the battery compartment and mounted the Pi flush to the battery cover flap to expose its ports.

    And PCP does the rest, as usual

    Pi Case

    A case that I cut out of a 2.5" thick block of wood using my CNC. This is v2 which took just over 5 minutes total to cut.

    Using Official 7" display, Pi 2, HiFiBerry Amp+ and a couple of 2.5" speakers.

    My pi PAL

    Hi; have a look at my "pi PAL".
    Its a Tivoli PAL, which I upgraded with a Pi Zero W running the awesome piCorePlayer.
    I wanted to have a very basic system with low energy consumption, so it is headless (-> use Smartphone as remote).
    Also, I use no external DAC, but simple PWM Audio similar as on the Pi3. That is good enough for a desktop radio.
    The power for the Pi is diverted from the PAL's internal batterypack, soldering an additional cable at the 4th battery (4.8V), which feeds the Pi +5V input.
    Another nice feature: No additional switches etc. needed to be added to the PAL - just a hole in the back of the case to feed the audio cable from the pi to the Aux input of the PAL. Sticking that cable in the jack does 2 things: The PALs Amp is switched from Radio to Aux (-> the Pi). And the Pi is powering up, as this cable is also the (only) ground connection to the Pi! A nice feature of the piCorePlayer s/w is that it runs completely in RAM, so you can pull that plug (i.e. switching from Pi Audio to Radio and powering the Pi down) w/o risk of SD card corruption.
    I am very happy with this setup. Also, battery live is pretty ggod: It is running almost a day already!
    See http://forums.slimdevices.com/showth...-and-Pi-Zero-W for some hurdles I had to go through to get it running.

    Parts list? Please?

    Thanks!

  9. #29
    Duh,

    glad you like it, but that is literally the parts list...

    The rest is "standard" or came from the parts box.

    • Raspberry Pi Zero W
    • "Audiophonics DAC Sabre ES9023 I2S vers Analogique 24bit/192KHZ Raspberry PI" (search this in ebay)
    • "2004 LCD blue Display for Arduino HD44780" (again, this should produce a useful result in ebay)
    • EC11 Rotary Encoder
    • DIP4 push buttons
    • bunch of 10k pull-up resistors
    • IR Receiver 38 kHz TSOP4838
    • the driver for the display background lighting is a BC546B with a 10k base resistor, any transistor will do the job
    • 10k trimpot for the contrast
    • since the pics were taken I added a 2200uF Panasonic FM cap across the power input under the DAC board
    • the box came with cotton swabs
    • the perspex is 3mm. My hardware store cuts them to measure as small as 10cm, 40ct a pop.
    • all bolts and nuts M3


    Any questions just ask.
