Hacking $15 Webcams for True Color Infrared [DIY]

What if you could see colors that the human eye isn't even designed to detect? In this video, we dive into a three-month engineering challenge to build a "True Color" Infrared (IR) camera using nothing but three $15 webcams and a Raspberry Pi. Most "infrared" photos you see are false color, but this rig captures three distinct narrow bands of near-infrared light and maps them directly to the Red, Green, and Blue channels of a standard video composite. The result is a surreal, real-time look at the "invisible" world. What’s inside: =========== The Hardware: Hacking cheap CMOS sensors by removing IR-cut filters and adding custom dichroic filters. The Optical Build: Why we moved from a complex beam-splitting prism to a side-by-side lens array. The Software: Overcoming "The Windows Problem" (USB serial number issues) by moving the entire capture rig to a Raspberry Pi using Python scripts. Post-Processing: Aligning separate MKV streams in DaVinci Resolve to handle parallax and timing drift. Field Testing: Capturing stunning IR footage in the tropical sun (and learning why you should always wear a hat and double-check your lens caps). Whether you’re interested in precision agriculture, meteorology, or just extreme DIY engineering, this project proves that with enough persistence, you can hack your way into a whole new spectrum. Resources: If you’d like the 3D print files or our (unsupported!) Python scripts to try this yourself, drop us an email at the address in the channel "About" section. Support the Channel: This is a hobbyist channel, and we love staying independent.
