Installing the RasClock – Raspberry Pi Real Time Clock

https://www.modmypi.com/blog/installing-the-rasclock-raspberry-pi-real-time-clock Installing the RasClock – Raspberry Pi Real Time Clock Module Introduction The Raspberry Pi is an ultra-small and ultra-low cost computer. In order to achieve this size and price, several non-essential items usually found on a computer had to be omitted. Laptops and computers keep time when the power is off by using a pre-installed, battery powered ‘Real Time Clock’ (RTC). However, this Real Time Clock module is not included with the Raspberry Pi. To keep time, the Raspberry

OMXPlayer Builds Update

http://omxplayer.sconde.net/   About OMXPlayer is a commandline OMX player for the Raspberry PI. It was developed as a testbed for the XBMC Raspberry PI implementation and is quite handy to use standalone. OMXPlayer has big dependencies that take long to compile on Raspberry Pi and usually without sucess, so I decided to make a build-bot for creating binary distributions for Raspbian (Debian with hard-float for RPi). I didn’t wrote the code, I just provide the binary packages. If you have

HOWTO: Boot your Raspberry Pi into a fullscreen browser kiosk

http://blogs.wcode.org/2013/09/howto-boot-your-raspberry-pi-into-a-fullscreen-browser-kiosk/ HOWTO: Boot your Raspberry Pi into a fullscreen browser kiosk It seems there’s some demand for knowledge of setting up a full-screen, browser-based kiosk on the all-singing Raspberry Pi. Here at Watershed we’ve done this, to drive the screens of our digital signage system. Although we complicate matters a bit (we net-boot the pis, which requires a few extra tweaks – see our blog post on net-booting raspberry pis), we thought it’d be useful to document what we achieved: automatically running

Looping video playlist with Omxplayer on the Raspberry Pi

Looping video playlist with Omxplayer on the Raspberry Pi http://www.cenolan.com/2013/03/looping-video-playlist-omxplayer-raspberry-pi/ The Raspberry Pi comes with an awesome little video player called Omxplayer that is very capable of playing back full 1080p video perfectly when encoded correctly in H.264/AAC. One problem is the current lack of playlist support in omxplayer, so this post explains how to create a bash script that will permanently loop through and play a directory of videos.   First install omxplayer: sudo apt-get install omxplayer Now create this script named for

Looping videos seamlessly OMXPlayer

http://www.sundh.com/blog/2013/10/loop-videos-seamlessly-omxplayer/ Looping videos seamlessly OMXPlayer Ellen 16:30 on October 15, 2013 As I looked for different solutions for looping videos on the Raspberry Pi seamlessly I eventually came out with a solution that worked quited good for videos looping with sounds. Looking at the possiblities of using the existing example of hello_video/video.c to loop a video wasn’t an option as sound was not supported and syncing sound was not something I wanted to spend time on. Instead I looked to jbaiter’s OMXPlayer library pyomxplayer build in
