![]() ![]() I did this because otherwise the microcontroller would dangle from the wires and they’d frequently get cut. The other hardware-related aspect of this is a small box I designed and 3D printed to house the microcontrollers. I also added a small switch so I can cut power to the whole assembly when I’m not using it. The LEDs are also connected to the batteries and the output pin of the WeMos, and that’s pretty much it for the schematic. I’m using a WeMos D1 mini as the ESP8266 board, with its 5V pin connected to two 18650 3.7V batteries in series, which usually provides power for around two hours of shooting, depending on LED intensity. The hardware didn’t really change at all from the first iteration. The control box, 3D-printed case and battery pack. I looked at the first two search results, saw that none of them resembled what I had in mind, said “Well, this conclusively proves that nothing like this has ever been done!” and started working on it. The second thing I did was what every self-respecting inventor does when they have a groundbreaking idea: I searched the web to see if this already existed. I had never seen anyone do this before, so the first thing I did was what everyone does when they have a groundbreaking idea: I could set the camera to record a long exposure, then move the strip and trace a pattern in the air. The idea was great, I would use a LED strip to display images in mid-air, like those persistence of vision displays.
