Display of my LR window for Halloween. Runs on the same Allen Bradley SLC5/05 as my LR Christmas lights. The run from October 15th until the 31st. The upper strings that change color can have the timer changed by 2 PC's and a Windows 10 tablet running AdvancedHMI. The spider web has 2 spiders that don't show too well unless you get really close. I have a few timers sequenced to make the web flicker to look like what I think the bad electrical service in a haunted castle would do.

Set of lanterns originally from a Mr. Christmas set that I had wired together as a set as seen on my Bedroom Christmas Window video. I wired them into 7 individual circuits & changed the PLC output card to a TTL card. Each lantern now flickers individually and after a few seconds they turn off for a about half of a second in order. This is run on a SLC5/03 controlled by 2 PC's running AdvancedHMI through an Ethernet COM port. The card is powered by a 5 volt power supply with the voltage turned down to 3.7 volts (to be gentler on the 4 volt bulbs). The steady on time and the pulse time can be changed by either HMI. I place these lanterns on the sill of my bedroom window for Christmas.

Christmas tree wired with 96 sections of lights cut into 12 volt sections. Originally designed for an outdoor flagpole tree of lights. Consists of 16 strings of 6 sections each, using 96 PLC outputs. For the effect of the lights the video was taken before any ornaments were placed on the tree. Each section is controlled by one of 6 - 16 output DC cards on a SLC 5/03 rack. Originally I had it powered by a 12 volt 3 amp power supply. but as I added more sections I found the supply got overloaded with only a quarter of the lights on, so I upgraded to a 30 amp, fan cooled power supply (with all lights on it pulls just under 16 amps with the voltage reduced to 11 volts). The PLC is connected to a Ethernet COM port through a WiFi access point and controlled by one of 2 PC's I have running AdvancedHMI.

Wreath I programmed using a Siemens S7-200. Cut a string of lights into 10 sections of 24 volts to run off the DC power supply & the PLC's DC outputs. The outputs are controlled by a counter that counts up to 87 based on a timer set at 0.42 second pulses.

3 sets I have in my Living Room window for Christmas. Running on an A-B SLC5/05 with 2 racks, and controlled by 2 separate PC's and a Windows 10 tablet all running AdvancedHMI. The 7 element set across the top of the window is also activated for Halloween (with 7 cat lanterns) and Easter (7 Easter eggs). The display is programmed with separate start & stop times for November/January and for December. They are programmed to be on from November 22nd through January 3rd.
