A live-coding lighting controller, building on the Open Lighting Architecture with Clojure and bits of Overtone.
0.2.1-SNAPSHOT code in the next few days I would greatly appreciate it.
Since we rent the Fixtures only for sunday I can't test anything but the LED Strips before that day, but it might be possible that I can get my hands on some PAR 64 cans for testing tommorrow.
We are using a Pioneer CDJ for DJ'ing and I would like to use an OSC Client for the Tablet that sits in my closet all year.
I am doing this show every year but we were using some proprietary old software before and I wanted to find something better. I can always use that as a fallback.
I am actually doing another event in July where I seriously wanted to use OLA and maybe afterglow to drive ~ 5000 Pixels and the event on Sunday is a bit of a test to experiment a bit, while I have the equipment.
I wanted to use the salary from that event to buy a small moving head that I can use for testing.
Those are a lot of things to work on! It would be probably best to tackle them one at a time, but you should definitely have a backup plan ready for Sunday. As long as you are running the OLA daemon on the standard port, on the same machine as Afterglow, it should find it just fine. Otherwise you can specify a host and port with -H and -P.
You will need to configure your show to use the proper universes in OLA. When creating the show, you specify those using the :universes keyword argument, followed by a vector of the OLA universe IDs you want the show to control. For example, if you want your show to work with OLA universes 1, 2, and 5, you would create it like: (show/show :universes [1 2 5] :description "My Show")
Do the LED pixels show up as universes as well? I have not ever tried working with them. Mapping some of your pixels as individual RGB LED fixtures would be a good baby step to start with. But even if you have no lights hooked up, as long as Afterglow is talking to OLA, you can open up the OLA web interface and watch the channel values while you are trying to run cues in Afterglow which affect them. (I just realized that my Open OLA button on the home page will only work if you are running olad on the same machine as Afterglow, but you can manually point a browser to port 9080 on the right machine if you are running it somewhere else.)
Anyway, rather than writing a huge amount here, it would help to know more specifically where you are stuck. I have already written a huge amount of documentation on the Afterglow project page and in the online manual which will be a better reference than what I type here.
Did you install Cursive in IntelliJ IDEA? That is the best way to use Clojure in IntelliJ, according to my colleagues who use IntelliJ. I’m afraid I’ve never tried using Afterglow in Cursive myself, though: I do my Clojure development in Emacs with CIDER, so I won’t be able to be of too much help there.
The max 485 is just a differential driver IC. It just generates the electronic signal, not the digital part.
It works just through the Uart Pins of the PI.
The show worked out in some ways for me. The biggest problem is that I just can't get warm with clojure. It would probably half a year getting into it in a way that I can do anything with it.
But thank you very much for all the help :smile:
