Re: Power issues - Gotta be kidding me

Just to add a data point, I have an early Pi that has (actually had) polyfuses on the input and on both USB ports. The power issues drove me crazy. Even with a powered hub I got inconsistent behavior with a keyboard, mouse and wifi dongle plugged in. Shorted across the USB polyfuses and bypassed the...

Re: I made a Raspberry PI Laptop

I went searching around trying to find answers before getting a lapdock and it seems that there is some confusion on a couple of issues. One, almost all of the references I found specify the Motorola Atrix lapdock but the Droid Razr one works and seems to be more readily available. Second the lapdoc...

Nothing. When I apply power, the red light lights up but not video at all. And I just got this thing yest...

Re: AverMedia tuner

I have one of those tuners sitting in a drawer somewhere and I wouldn't even think of plugging it into a Pi. Not enough HW horsepower to run it and no SW to interface to it.

Re: Using a standard RCA '3-to-1' with the Pi

What you will likely need is a single RCA to RCA cable for the video. If you also want audio to the TV, then you will need a cable that has two RCA plugs on one end and a single stereo headphone style plug on the other end. These are commonly available cables. or you can make your own.

Re: Is there a command to update to to wheezy 2013-02-09

I had a problem recently using "sudo apt-get upgrade" after doing "sudo apt-get update" so I recommend doing the update first, followed by "sudo apt-get dist-upgrade" instead of the generic upgrade command.

Apt-get is not very graceful around network errors/problems, so make sure your network config is up to scratch.
Worked fine without the extra spaces and, no, the errors were not due to network issues.

Re: SD card end of life?

Sometimes the cards get corrupted. SOmetimes you can just re-image them but sometimes that doesn't work right either. If you have one that keeps giving errors, I suggest that you use a partition management program to turn the whole card into a single FAT32 partiton and then format it before trying t...
