Software:

Xlights (Moving from Light-O-Rama S6 Pro)

Hardware varies by holiday, this is what I have:

Show computer:

HP EleteBook 8770w - this is used for playing the show not programming it. 

Light Controllers:

Alphapix 4 X1 - Used for WS2801 bats and snowflakes and stars

Alphapix 16 X3 (bought used)

Alphapix Evolution X1 (built by hand, kit bought new)

Alphapix Evolution Long range Differential board X3 (bought new)

Light-O-Rama CTB16PC controller X3 (some have faulty outputs)

Holiday Coro dumb pixel controller x4 (mostly retired controllers)

Audio Gear:

Radio Transmitter: CZE-05B

Speakers: Yamaha NS-AW194 Black

Amplifier: Sony STR-D365

Phone Audio App: pulsemesh.io (free version)

Pixels From:

HolidayCoro.com - controllers, coro, cables, etc. 

MagicalLightShows.com - My favorite pixels 

(other sites used, all are either out of business or not recommended by me) 

I buy used when I can to save money but sometimes buying new is the only true reliable option.
