Adding DMX to a cheap fog machine!

I add DMX control capability to a cheap fog machine using only items I found in my home. ⚠️ This project comes dangerously close to high voltage. Don't do anything you see unless you are comfortable and qualified! ⚠️ This Chauvet Hurricane 700 – circa 2010 – uses an IEC C13 inlet on its chassis to connect its included "FC-M" model wired remote control. I create a "replacement" remote control interface that features DMX control of the unit using an Arduino-based microcontroller to speak DMX and control a relay. This replacement "remote" gets its power from the fog machine's remote control port, which supplies 120 volt mains power to the remote! I investigate the supplied remote control, prototype a circuit to control it, and create a printed circuit board (PCB) to house the final version. This is meant to be a silly/fun project, please don't take it too seriously. Would I use this on a professional job or connect it to my expensive lighting console directly? Nope. 0:00 Introduction 0:44 Included remote demonstration 1:17 Remote disassembly and schematic 3:34 DMX circuit parts 4:50 DMX circuit schematic & prototype 8:37 Teensy/Arduino sketch code 10:37 Testing fog machine power 10:57 Patching DMX lighting control board 11:35 Testing circuit prototype on fog machine 11:53 Creating PCB layout 14:03 Toner transfer and PCB fabrication 16:49 Creating a "case" 19:15 Final DMX fog demonstration
