Re: Definitive working guide for setting up a GPS time server?

Hello, I never did get it working. I tried several times, got frustrated and moved on to something else. I got GPS and PPS data but once I got those working I lost GPS data. The several attempts that I got to the point of getting ntpd up and running, it saw both GPS and PPS and either gave GPS/PPS a...

Definitive working guide for setting up a GPS time server?

Hello, There are lots and lots of guides out there for doing this but they're mostly out of date and don't seem to be compatible with Raspberry Pi OS Buster. My hardware is working, I get a lock and I get a PPS output. It works well, like the Adafruit Ultimate GPS HAT but with PPS on GPIO 15. It's t...

Re: Pi-hole: Unable to log in via SSH.

Thank you for replying. I was under the impression that the login for SSH was supposed to be the same as the one for the web Admin Console. No - over SSH you're connecting to the OS that's on the Pi, in your case DietPi. You would use the default username and password for the OS, unless you changed...

Holy partitions, Batman!

Yeah that drive does not look right!

You may need to install ntfs-3g to read it. It's probably formatted NTFS.

But, looking that weird, I wouldn't be surprised if it's completely corrupt.

Re: RPI4 USB C Power Delivery negotiation

No, 3A is the maximum power a USB C cable can deliver.

https://en.wikipedia.org/wiki/USB_Power_Delivery#Power

Anything more than that requires USB-PD, which the Pi4 is unlikely to support as that would increase cost and it is adequately powered by 3A.

Re: Powering a RPI 4 + 2.5" HDD connected to USB 3.0

Well as I indicated in my response above, in my opinion - you should spread the load over more than one power supply. Yes, you indicate you want to reduce cables but if you rely on the hub for everything including powering the Pi you will need a substantial power supply for the hub as the Pi4 alone ...

Those cheap/old LCD displays, the grey ones from the 80s, are all transparent.

Be careful here, as soon as these ports are exposed, they'll start getting hammered constantly. Make sure everything is secure before you do this - it may not be a big deal if your Pi gets owned, but it could provide a gateway to the rest of your network that might have much juicier targets.

The Zero W's Bluetooth does not support the proprietary aptX. Your best bet would be to use a separate USB aptX Bluetooth adapter.
