Man builds device to help Nigerian military
The young man, known online by his TikTok handle @david.invents, posted a video tracking his response to a follower’s request. The user asked him to design something practical to tackle insecurity in the country.
In the footage, the creator accepted the challenge before laying out various electronic components on a wooden table. He carefully soldered wires onto a custom circuit board, fixed infrared light-emitting diodes, and mounted the lenses into a modified cardboard casing.
The technician tested the unit in complete darkness inside his compound to prove its efficacy to his audience. The video displayed a stark contrast between what the naked eye could see and the illuminated image captured through the lens.
He said:
"It’s dark but I can see very clearly. NOPE, it’s not black magic it’s science. I’m standing in the middle of my compound right now. It’s 9.32pm. But with my self designed NVD on my face, I can see clearly."
The screen shifted to show a purple-tinted view of vehicles, a nearby wall, and window frames that were otherwise hidden by the night.
