Re: Ethernet hub?

Your definition of "passive" and mine differ. Passive doesn't mean unpowered, passive means uncontrolled. I don't think you'll find any kind of ethernet equipment that doesn't need a power supply. I've learned passive to mean no added power, IE a passive USB hub vs an active hub which required adde...

So its 100% passive? No external power necessary? The power port in the pictures confused me.

Guess that solves my problem then. Thanks for the help.

Re: Ethernet hub?

I'm looking specifically for a passive hub, unless there is such a thing as a passive switch, but doubtful. I was hoping to just "tap" in to an existing line temporarily with as few wires involved as possible.

Ethernet hub?

I have a situation where it would be VERY helpful if I could use my laptop alongside a Raspberry that is in some location. The issue I have is, WiFi is not available, and there is only 1 Ethernet cable (For the Pi). So I thought a small Ethernet hub would be perfect for gaining a temporary port so I...

Hopefully a simple question. I have 2 Pis that are close together and it would be a great space saver if I could have them powered from a USB hub.

Re: Static IP across multiple networks?

Does the apple store have an app like Fing, which can list out the IPs of whatever is on the wifi network? If you know the Pi's mac address, you can use such an app to find its IP address. Or if you have an android phone, then you can use... Fing! XD

Re: Could I use solar power with this battery pack?

Depends on the solar panel. They are slow and inefficient, so the size/number of panels may not fully charge the battery in a day, or even 2 days. Ive looked into solar power myself, and ive estimated you would need about a 20-25k mA battery to power the Pi for 24 hours, and granted you might not be...

How would us having an image help you if your internet sucks? Are you talking about physical SD cards that are already imaged? If so, that would be a waste of money and time to deal with shipping. Download the image via the torrent would be faster then shipping.

Re: Program to save ip address in text file in sd

Talk to your network administrator, who should be able to set his router so that when it sees the mac address of your rPi, it always assigns it the same IP number, which he'll be able to tell you. That way you can write it down instead of storing a new dhcp ip address on a headless device at an unk...

Re: Can I set up AP, and connect to Internet using wifi dong

One dongle is possible, I think, but the quality of the connection would be questionable as it has to divide its time between supporting the connected devices and communicating with the main wireless AP.

Yeah, 600mA is a stretch unless you run headless. 1A power adapters are rather common to find as they are the standard for the vast majority of cellphones. My phone actually has a 1.2A charger.

Need a bit more information. If you are looking to set up wifi then that is a different ballpark unrelated to the Raspberries.
