Five generations in and it finally gets radical features such as: - a power button - a real time clock Crazy it took this long but finally, seriously. Downsides here are that it might need more active cooling whereas previous generations worked without it. Also, ugh: > Gigabit Ethernet, with PoE+ support (requires separate PoE+ HAT)
What would someone excited about the improved specs on the 5 be using a Pi for? I have 1-2 of each gen, but to me, they aren't devices I would use if I needed grunt. They're just solid little low power, low heat devices for running odds and ends. Curious what people who are pushing them hard are using them for.

What is (or would be) the "Tsundoku" equivalent for Raspberry Pi? I started with Pi-Hole a few years back but ended up with a commercial paid DNS resolver. The timeline usually goes like this -- will stumble on another interesting video of Jeff Geerling, then spend the weekend tinkering with the Pi, keeps running, forget about it, found it to be not needed, plugs off and is lying around.

NUCs cost hundreds of dollars, though. And they are probably 8x bigger, if you start stacking Pis.
Rasperry Pi board easily cost hundreds of dollars, too, once the scalpers have bought up the little stock that is there.

True, I've gotten Pi 4s pretty low (< 1W), disabling the LEDs, Ethernet, HDMI, and USB controller, but it's never gonna equal a proper suspend.
How did you disable the LED? I mean I can disable LEDs via /proc but not in config.txt correct?
# Disable Power LED after boot
dtparam=pwr_led_activelow=off
# Disable SD card activity led
dtparam=act_led_trigger=none
dtparam=act_led_activelow=off
# Disable the ethernet LEDs - these are Pi4 specific values.
# Look in the docs for the values for other Pi boards.
dtparam=eth_led0=4
dtparam=eth_led1=4

Won’t you still need an NTP or a GPS time module unless the RTC has a battery backup? How many applications would you have where timing is critical but you won’t have an external time reference that would be still viable without a guaranteed power backup?
Nobody said anything about not having NTP in the loop! Here's the deal: RPi The first thing we did was deliver 12V down the wire with a high quality power supply. Then we used UBEC buck converter modules (intended for RC quadcopters) to deliver power directly into the Pi via its pins. However, even now you're just chasing physics. There's no way to send a command to all of the Pis to do something right now . Instead,…
Out of curiosity, does 5V/5A USB-C changer common? All of my USB-C Chargers has 5V/3A only.

> When using a standard 5V, 3A (15W) USB-C power adapter with Raspberry Pi 5, by default we must limit downstream USB current to 600mA to ensure that we have sufficient margin to support these workloads.
Therefore 5V/3A can still boot RPi5, but it cannot provide enough power to its USB-A port. Therefore it cannot use something like 12V/2A, since RPi5 doesn't have transformer circuit on its board.
