Good to see some stocks are available.
Just HODLing for my Pi Zero 2W
I've bought stuff from these guys for many years. They rate highly with me, great service, excellent prices and support that other companies should attempt to match.
Same with me. Bought the original Pi Zero, but looking to upgrade now.
Yep, awesome company. Just check out their Google Reviews!
Hi, would you happen to know which Pi would be ok for a pihole? The Pihole website says anything more more than 512mb ram is good.
Also do i need to get a heatsink and fan? I would definitely get the case
Pi Zero 2 W works great for Pi Hole I have mine just powered from the usb port on the router too.
Already sold out! Damn. Thanks anyway op.
I just purchased one, they say in stock.
I'll go back!
Says 'in stock' but I keep getting 'the product you are trying to add is not available'. Sad.
Same here, sold out, I only just got the email saying they were in stock too. :(
Hmmm maybe it’s because I already had it in my basket from earlier?
They’ve taken my money, maybe they will cancel it later on today
Any use cases for Pi Zero W? I've migrated to a VM for home automation. Got two Zero Ws unused. Terrible for home automation as the SD card dies eventually corrupting everything slowly enough before you notice
I was thinking of the home automation use case. Where are you running your VM? On a desktop/laptop which is always on?
Using an old Surface Pro 3 tablet with Windows 10 and VirtualBox. Backups much easier to make and restore than cloning SD cards from my Pi. Also becomes hardware agnostic so I can port elsewhere when my Surface eventually dies. Was considering moving to a tiny micro PC for the extra ports but laptop has a battery which helps to keep things going in the even of a surge or outage
I'm using one to monitor a UPS and wirelessly report back to Home Assistant (running Raspberry Pi OS and NUT).
You may need to get one of those high endurance cards to mitigate the SD card failure
I’ve been running a Pi Zero W in my outside electric meterbox, where it’s dirty, dusty and geckos run wild, monitoring two electric meters and a (non smart) solar inverter. It’s been running faultlessly for 4 years, on the same SD card.
Classic PEBKAC.
home assistant smashes SD cards tho :)
Yeah who would've thought running a database on an SD card would go well…
I've had non DB applications running on the same SD card for literal years, outside, in a hot garage etc etc
They're fine if you use them with disk IO in mind and safely shutdown.
Use an SSD instead. You can boot off USB SSD now with the Pi 4. Have a cheap 128GB Kingston SSD in an external enclosure running my Home Assistant. Beginner at HA but basically just imaged the drive with rpiimager and you're up and running. Keep backups in the cloud and to restore/repair/replace just reimage with HA and restore backup (dont ask how I know this 😂)
And yes Core are good for price and service.
How do you do this? LDR Sensor connected to read the LED pulses?
Yes, two LDR each attached to a sensor module, and mounted on the meter LEDs, and an RS422 to USB converter for the solar inverter. I log the data to the SD card, and occasionally extract it into Excel to generate charts, etc
@BigBirdy: hey BigBirdy check pvoutput.org
if you already have the data it should be easy to add steps to send to there
Pihole.
Got it running a Zero W and it runs fine, nearly 2 years and there's never been an issue.
piaware, pihole or adguard, nut box for ups, smokeping box
i usually install https://dietpi.com/ and then install what i want on top
You can use them for sensors for your network. I'm running a Pimoroni Enviro plus, and separately a CO2/temp/humidity sensor. These push back to InfluxDB both via MQTT and also direct write to the database - so less wear on the actual card in the Pi Zero W.
As it is basicaly a standard Pi OS install, with a few drivers and a self-starting python script, it's quick and easy to reproduce if it fails. The load falls to an SSD on the server.If you own a 3d printer: Klipper
I'd buy them off ya for my 3D printers if you're not using them hah.
Does anyone have a good solution for the SD corruption issue? Is it possible to run a proper NVME drive in a USB enclosure to boot off of? I've lost a few Raspberry Pi systems in the past through the SD card failing…
Yes you can now boot and run directly from a USB port, either a more reliable USB drive or an SSD/NVME. The newer Pis have this baked in, older ones may need a reflash.
The new Pi OS also has a SD card backup function, so you could also use this to keep a spare copy.See my post above 😊
stick an old usb thumb drive in it, mount /var/log to that…
and/or for the cases where i don't need super fast response (eg for the 2 pi I have running pihole) I have an old spinning disk, (640GB external drive) attached to one of the pi in the house, and mount the log folder to that with nfs
YMMV : Maybe others might notice a slow down, but I can't tell any difference before and after doing that.
USB thumb drives, speed and reliability is roughly in the same class as SD cards, maybe just a tad better.
Anyone willing to get Pi 4 8GB model should think about a SATA SSD.
@netsurfer: true, but if others are like me, a supply of old (eg 8GB) thumb drives is not too hard to find in the parts drawer/box. Using them means no additional cost, no wait for delivery, or trip to shop to purchase.
You could technically run NVMe SSD via USB with Pi 4, but it is an overkill for USB 3.0. A SATA SSD would be more than sufficient.
Sounds like you need to figure out a better backup. Also, try to shutdown properly in linux, rather than just turn it off.
While Core Electronics is great, some of their Pi 4 accessories are not very well priced at the moment…
As many others have pointed out you can use an external SSD. A word of caution with SSDs: not all external SSDs will work. I have one NVME enclosure that gets detected by RPI 4, and I can see it with lsusb, but the system can not see the drive. I haven't tried using it with a powered usb hub in case the NVME drive is not getting enough power. But, with the costs of powered usb hubs it was cheaper to buy a 2.5" SATA SSD and enclosure. The 2.5" SATA SSD works. I could have tried to run the PI and NVME enclosure from the same power brick with a USB Y cable to the enclosure connecting the enclosure to PI and power brick but that is a mess of cables.
Anyone tried android os on these P4 8gb and how good is the performance.
Back in stock it seems.
All gone now in the morning just now. Out Of Stock again.
Thanks. I've been meaning to get into the Pi, and this seems like a good deal to start with.
Also bought the Argon One v2 case. Really neat that this case allows access to the GPIO pins.
Standard Auspost delivery was $6.85.
