OLA is Open Lighting Architecture .. lets you convert one type to another .. but generally it has an ArtNet interface and lots of fun output interfaces including SPI. For some thoughts: last year I built 4 4'x8x16' steps we used on stage. We drove them with SPI Controllers .. that worked great .. but was expensive. The reason I went pi is the pi itself is $35 and built in wireless .. fadecandy is $22 .. can drive a pixel set of 64x8. This year we're building 12 steps 8'x8"x9" with 6 rows of 64 px driving off the QLC. I have githubs of the ansible code I use for all of this .. happy to share.

Some things to consider:

• PI - there is raspberry pi zero form factor .. which is quite small ;) I am experimenting with those now as full replacements for the Pi-B's and C's I have ( I used to teach with PIs so I have a bunch of em )
• interference - 802.11 can be impacted by bad dimmers .. things near by ( high amperag fryer, microwave), channel collisions with existing APs and most easily .. if it's visible lots of things will try to connect even with a password. Set your wifi to NOT broadcast the BSSID. And check the wifi spectrum when you get to a venue ;)
• amperage .. make sure you have enough to drive your px .. specifically something north of 80 px in a single strand you'll wanna inject power on the other end. The overall power supply doesn't have to be crazy .. but investing in a good volt-ohm-amp meter meter is worth it for testing and validation.
• universes .. I've successfully transmitted 4-6 U over a single SSID of 802.11bng . If each px is individually addressed .. and you're using RGB .. then each px is 3 DMX channels. Each U is 512 channels .. that gives you 170 px in a single U and QLC doesn't handle crossing U in a single fixture.. but does handle things with matrixes .. so you'll have to play around with the config and layout. You can always use the same channel(s) for multiple fixtures of the same type.
• road-rash .. touring with such a rig .. plan spares of everything and have a test program you can run to make sure it looks right. The LED strips don't handle LOTS of bending .. but some. The "Sticky" on the back is for shit. plan clear tape or something else to make sure they stay mounted whereever you're putting them. Also .. the "joining" kits you can to connect 2 strips work reasonably well .. BUT they dont' like to move alot. We've started soldering them on to the strips once we have the design set.

Please feel free to reach out any time .. do lots of work in this space and always willing to help ;)
