Re: Hard disk always connected - dangerous?

it was mentioned somewhere in the whole forum that HDDs better off and more reliable running, continuously spinning their platter than having it start and stop. So the danger to the HDD is frequent starts and stops.... which must be avoided as much as possible.... alas @OP you dont have to "fire and...

Re: Raspberry Pi4 EEPROM update package - beta

I always thought this is on purpose and working as designed because this feature is intended to signal to something else that the machine is ready for poweroff.... Come to think of it I think you're correct on this.... I may have confused it with other setups that does not have it enabled. hmmm.......

if you do intend to use the RPiA form factor... then something like that is OK if you intend to use RPiB form factor... it may be a bit a "tight squeeze" and/or nightmare to route the wires... also lets make it clear, you want the amp to drive the speakers, then if a headphone is inserted the audio ...

if you mean raw-naked speakers, you can solder those (via some connecting cable) to the RPi' s audio terminals but will not get any meaningful audio output from those...unless the distance between the speaker and your ear is about 20mm if amplied/powered speakers as @klricks mentioned, then you'll b...
