This is incredibly instructive - for me anyway!
- You might be the first person to use the new palettes feature!
I can immediately see a really nice new feature - “SET DEFAULT PALETTE”. If you had that you’d lose half a dozen lines of code or more.
Nice! Yeah, that’d been a nice touch. In truth, the amount of actual code to the results is super small so I wasn’t hurting. The bigger pain point was finding where it was supported and which animations didn’t yet use it. Glad seeing it used is helpful.
- Question - I see you’re using numpy colorlists (because you have the numbers: float32 section enabled). Did you notice any performance differences with that?
It’s particularly noticeable in real-time things like fades for me, less so in other things.
I don’t think I was using a fade at the time I switched, but I did see it improve. It absolutely wasn’t slower so I went with it based on your comments in docs. I haven’t seen any problems with it.
- Pro-tip - for re-use!
Consider dividing this into two .yml files:
File base.yml:
shape: 160
driver:
typename: SPI
ledtype: WS2801
interface: PERIPHERY
c_order: RBG
numbers: float32
layout:
typename: strip
brightness: 50
palettes:
halloween: [lime, orange, purple]
and animation.yml:
animation:
typename: .sequence
length: 30 # Seconds before switching to next item in the sequence
animations:
- typename: $bpa.strip.Wave
color: lime
- typename: $bpa.strip.Searchlights
palette: halloween
- typename: $bpa.strip.ColorPattern
palette: halloween
- typename: $bpa.strip.LarsonScanners.LarsonScanner
color: orange
- typename: $bpa.strip.PixelPingPong
palette: purple
fade_delay: 50
- typename: $bpa.strip.Rainbows.RainbowCycle
palette: halloween
- typename: $bpa.strip.LarsonScanners.LarsonRainbow
palette: halloween
- typename: $bpa.strip.PartyMode
palette: halloween
Then you can run your project like this:
$ bp base.yml + animation.yml
Three big advantages:
- You can have have the same strip and different animation files halloween.yml arbor-day.yml new-years.yml
- You can keep adding to your palettes and aliases so they’re always available in all your projects.
- You can quickly “audition” new animations from the command line - like this:
$ bp base.yml + ‘{animation: $bpa.strip.Rainbows.RainbowCycle}’
You can divide your project up into lots of tiny files that way. I have a document planned detailing workflow, when I get past these somewhat obscure bugs I’m working through (POV, who knew that existed? :-D)
Oh, this’ll be really useful for my bigger project where these lights will ultimately land. Also, see how that audition feature would have been useful as I was trying to figure out options for animations as well. Thanks!

I used this little project code to add a little fun to the office halloween party. It took me awhile to figure out sequence and some other things so I thought I’d share so other searches might find.
