"Santa Sleigh, WiFi Edition" uses "Motorized WiFi Chassis" (https://www.youmagine.com/designs/motorized-wifi-controlled-chassis) to create a WiFi enabled remotely controlled Santa Sleigh.
My wife's implementation of Santa Sleigh, WiFi Edition is shown in the first photograph and video. The second photograph and video is, well, mine; I used a "dollar store" soft Santa ornament as a stand-in for Mr. Claus himself.
You will need to complete Motorized WiFi Chassis prior to completing Santa Sleigh, WiFi Edition.
As usual, I probably forgot a file or two or who knows what else, so if you have any questions, please do not hesitate to ask as I do make mistakes in plenty.
