Come join the fun and create a Halloween, Christmas, or whenever light show (karaoke, dance party anyone?). LightShow Pi will synchronize the lights to music using your Raspberry Pi as the central controller (i.e. no external computer necessary). LightShow Pi automates the entire creation of a light show using the frequency spectrum of the music that is playing!
There are also many community built add ons, including SMS control (e.g. changing the volume via sms, or allow your neighbors to vote for the next song in the show), pre and post show lighting configuration, and many more! Welcome to the community, we hope you enjoy the fun!
So, what happens when you turn your “little” home DIY holiday lightshow project into an open-source project? Amazing things … tons of new features (see below), amazing community involvement, and lots of fun!
I’m happy to announce the release of Version 1.2 of LightshowPi just in time for this year’s holiday season. It rolls up many changes made over the last year+ by several developers into the stable branch. If you’re already using LightshowPi and you’d like to try out some of the new features – the easiest way would be to do a fresh / clean install:
So, what’s made it into this new release you ask?
- 3 to 4 times speed improvement by utilizing GPU for fft and other optimizations (thanks to Tom Enos, Colin Guyon, and Ken B)
- support for streaming audio from pandora, airplay, and other online sources (thanks to Tom Enos and Ken B)
- support fm broadcast on the pi2 and pi3 (thanks to Ken B)
- multiple refactors + addition of comments to the code + clean-up (thanks to Tom Enos)
- add the ability to override configuration options on a per-song basis (thanks to Tom Enos)
- support pagination for the SMS ‘list’ command (thanks to Brandon Lyon)
- support for running lightshow pi on your linux box for debugging (thanks to Micah Wedemeyer)
- addition of new configuration parameters to tweak many facets of the way lights blink / fade (thanks to Ken B)
- addition of new configuration parameters to tweak standard deviation bounds used (thanks to Paul Barnett)
- support a “terminal” mode for better debugging w/out hardware attached (thanks to Anthony Tod)
- many other misc bug fixes (see Issues list for more details)
