Big Ben for your Raspberry Pi
This is a project based on http://www.instructables.com/id/Raspberry-Pi-Big-Ben-Clock/ which turns your Raspberry Pi into Big Ben - with chimes every hour and half hour.
The original instructable worked well, but it sounded un-natural to have each hourly chime finish before the next hit.
This version uses SoX to play the chimes and outputs a more natural-sounding hourly chime. Note that the mp3 format for SoX must also be installed libsox-fmt-mp3 or you can install SoX and all formats with sudo apt-get install sox libsox-fmt-all
After configuring the script, you must set an entry in your Pi's Crontab to schedule the chimes.
