Are you ready to create breathtaking water drop videos like a pro? I've developed a DIY system that uses an ESP8266 module, WiFi connectivity, and opto couplers to control the precise timing of water drops. With this project, you can create stunning visuals by synchronizing the release of water droplets with camera flashes and triggering high-speed cameras. The system is incredibly versatile, allowing you to experiment with different LED lights, valve configurations, and even colored waters. You can use it to create mesmerizing effects like "drop-on-drop" or add an extra layer of complexity with multiple valves and electronics. To get started, I've made the source code and electronics plans available for free on The Camera Trigger repository. If you're ready to unleash your creativity and push the boundaries of water drop videography, check it out!
