Screen recording program/utility?

I've tried Googling this extensively and have been unable to find a simple solution (including searching the forums, so apologies if this has already been asked somewhere - I couldn't find it). I'd like to do video capture of the Raspbian desktop for making tutorials, like some of the popular Pi You...

Re: Any point to a 2A power supply, given the 1.1A fuse?

A cheap one might provide 5v at 150mA but when its supplying 1000mA the voltage has tailed off to 2v (or often worse). This is a great blog post where someone actually tested a bunch of different real and counterfeit adapters and shows the power curves - it's amazing (and disconcerting) how bad the...

Re: Any point to a 2A power supply, given the 1.1A fuse?

Oops - I thought I had email notifications set up for this thread, but never got notified of the replies for some reason. So, a belated thank you to everyone who chimed in. I got an interesting reply on stackexchange from someone pointing out that just because a power supply has a higher current rat...

Any point to a 2A power supply, given the 1.1A fuse?

I wasn't sure if it was better to post this here or in "Recommended Peripherals", so please let me know if this should be moved. I figured this might be a little more advanced than typical questions there. My question: it's my understanding, based on the official Raspberry Pi FAQ , the wiki , and nu...

Re: Default sudoers file?

So, this looks like an old post, but I have the same problem - I screwed up my sudoers file somehow (long story), and I have no idea what the original should look like! Luckily I have multiple SD cards and I'm installing a fresh version of Raspbian on a backup. It would be nice if I could just find ...

Force audio out over 3.5mm AND HDMI?

Hi, I know there are a lot of posts, like this one http://www.raspberrypi.org/phpBB3/viewtopic.php?f=26&t=40872 , about forcing audio output over the 3.5mm jack or HDMI. For example, if you have your Pi plugged into an HDMI TV input, but want audio to go to an external stereo system. Is it possible ...

Re: WiFi adapter working in regular Raspbian but not RetroPi

Answering my own question just in case anyone stumbles across this in the future: I was able to get WiFi working by starting over with a clean slate: Re-flash the SD card On first RetroPie bootup, when it brings you to the Player 1 button mapping screen, press F4 to exit RetroPie and go back to the ...

Quick update...the lsusb command does show that the Pi recognizes the wifi adapter: pi@raspberrypi ~ $ lsusb Bus 001 Device 002: ID 0424:9512 Standard Microsystems Corp.

WiFi adapter working in regular Raspbian but not RetroPie

Hi - this is a bit of a length post, but I'm trying to be as detailed as possible in reproducing what I've done to get to this point. Any help will be appreciated. I have two very similar RPi setups - one for work and one for play. The "work" version is running a pretty recent version of Raspbian (d...

Re: Invalid sample rate -9997 with PyAudio and pygsr

Ah. The only reason I'm using this webcam is because I already had it sitting around and it has a built-in mic. I have no need for video at the moment. In the long run I will probably do as you suggested and look for a dedicated sound card and mic. Thanks again for the help - still haven't had a cha...

Re: Invalid sample rate -9997 with PyAudio and pygsr

Hi - thank you for the very detailed response. I will try this procedure out in a little bit - but first, could you explain: - You are probably using a USB Sound Card. It has specifications, such as the sample rate. The problem is that the sample rate defined by pyaudio (and so by pygsr) differs fro...

Invalid sample rate -9997 with PyAudio and pygsr

Hi - I am a relative Raspberry Pi and Linux newbie, so I apologize in advance. I am trying to do simple voice recognition with the Raspberry Pi, to execute commands like turning the GPIO pins on and off for home automation. I got it working in a terminal pretty quickly using this great tutorial by S...
