Calling himself “Neular,” the inventor illustrated exactly how he had gone about the project with a series of photos published on image-sharing site imgur. It’s his only post on the site, but judging from his creation, the dad is clearly a talented craftsman.
To build the door, Neular constructed a shallow box using plywood and old 2x4s he had lying around. He then acquired a strip of “super bright LEDs” and secured them to the back of the box. Finally, he installed a touch sensitive Arduino Uno board and an automatic door opener.
Next, Neular turned his attention to the outside of the box. “I bought a large plexi-glass sheet [and] covered it in vinyl,” he wrote. “I drew the design on the back side and used a razor to cut it out… I just painted the back of it white to help reflect the light more inside the box.”
