Happy New Year!  I hope everyone's light shows this year were a hit, but more importantly - I hope you all had a blast building out your own light show.

I wanted to let the community know that I've created a new website for LightShow Pi, check it out and let me know what you think:

http://lightshowpi.org/

I'd love to highlight more photos / videos of various light shows built on LightShow Pi to include on the front page (like I'm doing with my original show and Chris's show).  If you are interested in having your setup highlighted, please send me the following (message me directly, or post in comment below):

(1) A link to an uploaded high resolution image of your light show
(2) A link to an uploaded video of your light show
(3) Your name (to give you credit on the site)

Feel free to upload your image / video to the community if you haven't already, and send me those links - or use any other repository you'd like, as long as I can access the links, and ensure that the video is publicly available.

Thanks all!

New to Raspberry pi. Trying to get Lightshowpi installed on my A+ but keep geting 404 errors at the wiringpi install and then the installed exits with code 0. See the pic for the errors. I have tried both install methods listed on the install page of lightshowpi.org.

The problem is not with wiringpi, it is with rasbian.org, you can manually setup your pi to use a working mirror or wait for rasbian.org to fix the problem.

Here is an update on my lightshowpi robotic drummer. I got the spine and one shoulder built today. I am going to need to add a helper spring or counter weight the tapped dowel before I attach the arm. Still waiting on parts for the other arm and head but it is looking promising. Off to the hobby store to buy the material for the puppet and some rubber O rings to pad and quiet down the solenoids. Now I need to figure out how to sew.

How do you fix an alsaaudio error?

Did you run the install script?  python-alsaaudio should have been installed with all the other dependencies.

To manually install  python-alsaaudio issue this command
sudo apt-get install python-alsaaudio

I doubt this matters much to basic operation of the code but im just checking to make sure!

I think mine did this once as well, issue with the ssl connection. I would just retry and see if it is successful the second time through.

What script do I have to edit to change the GPIO pins?

Are you wanting to setup the GPIO Pins? If you want to change what pins the program is using check out the config directory and the defaults.config file.  there is a setting named GPIO_PINS

Kernel panic on B Rev 2.

My brother-in-law and myself both got our lps set up in the last few weeks. Amazing piece of software! He is running off of a b+ plus, I have a B rev2. With almost identical wiring, outlets, and everything, using saensmart mechanical relays from banggood. If i activate more than three channels, I get a kernel panic a few seconds into a song. His b+ just barrels through.

I'm not sure if this has to do with the lower power consumption of the B +, or if it is just able to sink more current than the B. Has anyone else ran into any problems powering 8 relays and controlling them with the B revision 2?

I am wondering about how you guys are getting people to drive by. Newspaper ad or just word of mouth? I live in a town with <8,000 people and I might place a newspaper ad. I had one person come last season.

About this community

http://lightshowpi.org/ Come join the fun and create a Halloween, Christmas, or whenever lightshow (karaoke, dance party anyone?) - synchronizing the lights to music using your Raspberry Pi as the central controller (i.e. no external computer necessary). As of today, our software automates the creation of a lightshow using the frequency spectrum of the song that is playing back. There are also many add ons - such as SMS control (e.g. change the volume via sms, or allow your neighbors to vote for the next song in the show), pre show lighting configuration, and many others in development. Come and join our community and contribute to the project, we'd love to have you :-)

Here are some pictures on the progress on my robotic drummer. The solenoids have no problem moving the arms but the return springs can't take the weight. I am going to add some helper springs to balance out the levers and it should work perfectly. I added some heat sinks and a 5v fan in his butt to keep things cool. I am going to make the body out of sheet metal lined with material from a welders blanket just in case a wire ever smokes or the solenoids heat up. I am not forseeing any problems from my initial testing but better safe than sorry.

Hi all. First of thank you all for your hard work. I am currently using Pi2 and everything is working when I am play the file from the SD card.  NOTE:: I am a noob ::

The issue arrives when I change to Audio-in mode. I get the following message:
Traceback(Most recent call last):
 File 'py/synchronized_lights.py", line 537, in <module>
   audio_in()
 File 'py/synchronized_lights.py", line 206, in audio_in
   stream = aa.PCM(aa.PCM_CAPTURE, aa.PCM_NORMAL, cm.lightshow()['audio_in_card'])

I thought I would share a project I am working on. I am a musician who plays some small shows with vocals and guitar and wanted to add a drummer to the show. I am adding a pre recorded drum track and thought it would be a good gimmick to have a robotic drummer play with me. I am currently experimenting using lightshowpi to control a couple 12v linear solenoids. I am starting to build a Muppet style of robotic drummer using these solenoids mounted to a set of levers to actuate the drummer's arms. My initial testing has gone very well. Now it is time to build the skeleton. I will post some more videos as I progress.

@fragwits. Yes, something along those lines but on a smaller scale. Mine wont actualy be playing the drums, it will just be making the movements. Thank you for the link though, it gave me a couple ideas.  Right now, I have my tablet running the drum track through the PA. I am going to split the output of my tablet and run it in to the pi, simple.

For those lucky enough to live near a MicroCenter, they have the RPI2 in stock for $34.99 in store only.

Tempted as my local Microcenter has 4 in stock. However, the B + is also in stock, and only $20! I think the PI FM support tips me towards Bplus, although it will probably be updated to the pi2 at some point.

I had some trouble a while ago with PiFM not working and I believe I read that somebody was looking at an external FM transmitter. I recently came across a cheap 3.5mm to FM transmitter with selectable frequency in the trucking and auto supply section of my local Wal-Mart. If anyone is looking for one, that may work. (I don't have one and can't verify if it even works, but I did see it) I believe it is back there for truckers with no audio in port to stream their music off of a phone.

They work great, but they are only good for about 10 feet.
Some of them can be hacked to transmit a little farther, but not all of them.

I have recently set up a Raspberry Pi with Light Show Pi at my school for a project, I am trying to get the sms controls to work but even though I have followed the instructions nothing happens.

You might want to try directly running the check_sms script from the console and see if it executes without error.

I cant seem to get leds working with the gpio pins.

Perhaps best to stick with a b+ for now if pifm is desired? I need either b+ or pi2 as my B rev2 kernel panics if I run more than 4 channels...

Great project! I've build a little disco light from spare parts and it works really well! But I can't get the synchronized_lights.py to work on startup or reboot. Tried to use rc.local and crontab so far - but no luck with that. Did anyone accomplished this before?
