    In case some of you are not on facebook: Last night was the grand reveal of the Highlands Ranch High School marching band show Phobias. It was the Homecoming football game. The HRHS band has 78 members. We were performing John Fannin's Phobias. Fear of Spiders, Snakes, Water, being alone, wide open spaces, noises, fire, heights. https://www.youtube.com/watch?v=hSufUaKXEks


    We built 7 props. (6) of them are 1152 lights on 2" spacing on a 4x8' wooden frame. Frame is 4' off the ground making the top 12' high. Each of these six props has a Raspberry Pi 3 running FPP 1.8. Controller is a Falcon F4 (4 data line outputs) and a Falcon power distribution board to power 8 more strings. Stairs are 12 strings of 96 ws2811 12v lights. The 7th prop is a stair that is 6 feet wide and 9' tall. Each stair step has a 4x36 matrix on the riser. 1296 lights on stairs. Stair is powered by a Falcon 16. STair has FPP setup as Master unit.


    7 props, 8208 lights. These lights came with connectors on both ends.

    Each of the 7 props is battery powered by a 12v , 45AH battery. We are able to run the 8 minute show at least 3 hours on this, $88 battery.

    8.5 minute show was divided into 8 sequences, each segment was triggered using the big button plugin on FPP. This draws 10 buttons on a web page. Press a button and it triggers a playlist on the master, the six remotes all follow suit. We used an ipad to access the screen. It worked perfectly. There was a 1 to 1.5 second delay from the push of a button to the first note of music. Student running board just marked music to take this into account.
