Re: PI 4 and Ubuntu 20.04 (Focal) - Gigabit Issue

Do not turn off flow control. Er, well, actually try twiddling all the options. It won't catch fire. I mentioned it because I've seen flow control issues with Pis and consumer switches. It was probably old (100Mbit) Pis connecting to Gbit switches, though. It is older and may have a completely diff...

Re: Anyone tried ZFS on Pi 4 or planning to do so?

I am currently running on a Pi4 4GB with Ubuntu64. As you say, a simple "sudo apt install zfs-dkms zfsutils-linux" and you're done. I'm not saying Ubuntu is right for you. It has its own issues. If you really want to run on raspbian, my first guess is make sure you aren't running out of RAM while co...

Re: idea: replacing a large power hungry rack server, with Rpi computers

I think it is important to keep the limitations of the Pi when using them as servers. SD cards *will* fail eventually and should probably only be used for booting, if at all. USB is less reliable than SATA/SAS. You will probably experience the occasional disconnect requiring you to cut power/replug....

Give me an ssh port, vi, and a bunch of config files any day. RPiOS/Raspbian especially if you want gpio or Ubuntu if you want 64bit. Monitor with Netdata or similar if you want a dashboard.

Re: Pi Zero Screen + old Smartphone as Screen

The Pi Zero W is my favorite SBC, but this is kind of a fiddly solution, to be honest. If it was me, and I really had a $0 budget, I would just plug a keyboard into an old phone and use phone apps. If you are dead-set on using an SBC, 1. yes. or you could skip the phones, source $10 ili9341 lcd disp...

Case looks good. I'm not sure about using PLA for it though. The glass transition temperature of PLA is well within the normal operating temperature range of a Pi 4. I have printed PLA parts for use on my Pi4. I have only seen slight warping on one piece and that was a "harness" I designed to hold ...

Re: Has anyone tested how the Raspi 4 does with Netflix?

Netflix works fine on Pi4 and LibreELEC. I use the addon from https://github.com/CastagnaIT

I *think* it gets you 1080p, but I just reformatted that SD card to play with the new Raspberry Pi OS, so I can't verify.

Re: Pi alternative that supports DisplayPort Alt Mode and Power Delivery over USB-C

It sounds like a power splitter USB cable might work. It separates power and data, so the "data" could go to the pi, the "power" could go to a battery module, and the "both" could go to your display. HDMI for video. A separate cable to power the Pi. As for a different board, a quick google suggests ...

Re: Raspberry Pi Zero - Version 2?

While it would be nice to have a second core and 1GB of RAM, I wouldn't want to trade that for less battery life. Any new "Zero" board would have to come with low power states, sleep/wake, etc. for me to be interested.
I'm looking forward to hearing how the Giant Board performs vs battery life.

Re: Raspberry Pi control Relay with momentary switch

Where I live, using DIY relay circuits to switch mains power violates electrical codes and will void your fire insurance. I'd only use certified wifi-enabled (or bluetooth or zwave or zigbee) light switches and talk to those via the Pi.
