• pHAT BEAT Web-Radio based on Mopidy with ODROID-SHOW2 as display:

• autoplay specify playlist, after device has boot up
• display shows radio station, track info and some device infos. Auto refresh every 15 sec.
• RPi-Zero W overclocked to: arm_freq=1050 core_freq=500 sdram_freq=500 gpu_freq=500 sd_clock=100.000 MHz
• current consumption: ca. 390 mA via USB powerbank for RPi-Zero W (using WiFi) with pHAT BEAT (incl. VU Meters), stereo speaker 8 Ohm, Odroid-show2 display, usb hub with ethernet adapter

😃

cons:

• have to disable clean-shutdown because this script give rise to 100% cpu load. (normal running at 43 - 49 % cpu load)

Epic 👍

have to disable clean-shutdown because this script give rise to 100% cpu load

Try moving this line:
https://github.com/pimoroni/clean-shutdown/blob/master/daemon/usr/bin/cleanshutd#L65

To, below the fi line:
https://github.com/pimoroni/clean-shutdown/blob/master/daemon/usr/bin/cleanshutd#L66

eg:

while [ $daemon = "on" ]; do
    if [ $(raspi-gpio get $trigger_pin | grep -c "level=0 fsel=0 func=INPUT") = 1 ]; then
        echo "BCM $trigger_pin asserted low, system shutdown in $shutdown_delay minutes"
        daemon="off" && shutdown -h +$shutdown_delay

    fi
    sleep $polling_rate
done

• 🈯️ Audio fine with hifiberry-dac overlay
• 🈴 Fails with ALSA dmix for VU meter https://github.com/pimoroni/pivumeter
