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

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.
