I run my Piano 2.1 config with 2 x 5V feeds from an Anker battery similar to #5. The power sequence I use is below.
Powering down
Perform Menu, Restart, Shutdown and wait for the green activityr LED on the Pi to blink 10 times indicating the shutdown sequence is complete and power can safely be disconnected.
1. Disconnect power from the Pi
2. Disconnect power from the DAC
Powering up
1. Connect power to the DAC
2. Connect power to the Pi
Hello Tim
I want to develop a shunt regulated power supply (at least for my Allo Boss dac), and I would like to automate the power up (and down).
How much time does it take to turn on the raspberry after the dac ?
(... probably your question went unnoticed...)
I assume you need to find out how long it takes for the RPi to be fully functional while running Moode after Power ON. This would depend on several factors:
- the model of RPi
- the Moode version
- the booting device the Moode Player is installed upon (quality and speed of the uSD card / USB memory stick / classic or SSD HDD)
- the charasteristics of the RPi power supply
Probably is best if you time yourself the RPi as a 'standalone' player (SSH...?... I guess HDMI goes 'off' at some point but you can try...). Please let us know your findings (and characteristics of your RPi kit) if you succumb to run such tests
