Re: Raspberry Pi GPS For Wilderness Use

If you're only powering the Pi Zero W and the GPS communication device from the battery, then even better. Yes, the 4G hotspot would not be of much use to you if you were truly in the wilderness! Do you have a link to the tutorial and to the GPS device? I presume the GPS device also allows transmiss...

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 ...

Re: Raspberry Pi GPS For Wilderness Use

Ah, I understand now. It gets GPS data then sends it back to family and friends via a 4G LTE hotspot. Seeing that you have a Raspberry Pi Zero W then yes, your battery probably will give you 10 hours. I don't know about the power draw of the 4G hotspot or the GPS device but if they're not too high t...

Re: Transparent Matrix Displays

Those cheap/old LCD displays, the grey ones from the 80s, are all transparent. They require a polarized film placed behind them to make them visible as the electrical charge alters the polarization of the liquid crystal and the polarizing film placed at 90 degrees makes it opaque.

Re: modifying files on a mounted network share

Not sure about a Windows folder, but the following works well for my Linux share (with guest permissions):

Re: Can't access Pi over WAN

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.

That camera with a ribbon cable can only be connected directly into the Pi's camera port. There's no way to convert it to Ethernet as it's a "raw" camera and not an IP camera.

Glad that worked!

Note the "mount" command is a one-time thing, if you reboot you will have to enter it again.

Putting it in fstab as shown in the link is permanent and will reconnect on reboot.

Isn't that the point though? The Pi is powered by its own power supply and the hub by its own power supply.
