Part 3/10:
The creator has always been enamored by high-speed video recording but was initially deterred by the hefty price of commercial systems. Choosing a more cost-effective route, they employed an oscilloscope-based design to fabricate a ‘poor man's’ camera. The entire setup, despite its homecrafted nature, cost less than $1,000—a fraction of what commercial alternatives demand.
The camera makes use of a combination of light sensors and mirrors to track the light emitted from a laser pointer. With meticulous planning, the creator constructed a mechanism where the light sensor would record signals emitted from the laser as it hit various points on the wall, ensuring that the camera captured multiple frames and thus, pixel data.
