Box with a stand for a PS3 Eye camera to be used for infrared tracking

thingiverse

We crafted a specialized enclosure with an adjustable base to convert the PlayStation 3 Eye camera into a precision instrument for infrared tracking applications. A cluster of openings on the front of the container houses five 5mm IR LEDs, carefully angled to increase illumination area coverage. A compact pouch within the box accommodates a USB-B connector and a 5mm barrel jack, ensuring reliable power supply for the IR illuminator. We utilize the camera's infrared capabilities to pinpoint head movements and position adjustments on a partially transparent mirror in our cutting-edge augmented reality system.

Should additional components be needed to achieve precise tracking capabilities, feel free to print custom-made box enclosures for the PS3 Eye cameras on your 3D printer via this link: https://www.thingiverse.com/thing:820765. Moreover, if required, you can construct your own set of infrared cameras tailored for head tracking using these specific guidelines: http://www.thingiverse.com/thing:820888. **Operating Guidelines** Each IR-equipped camera container contains twelve 5mm IR LEDs sourced from OSRAM, utilizing their LD 271 product series. The LED units are interconnected in four series chains with distinct current draw profiles to maintain optimal performance levels. We specifically chose series resistors for each of these chain configurations to limit current draw per individual LED to around 40 milliamps. A customized circuit board was fabricated within a PC housing and connected via a standard Molex connector to deliver a reliable 9V/1A power supply to the electronics board from a DC voltage source. Two series resistor combinations – 68 Ohms for five-series LEDs and 33 Ohm for six-series LEDs in a single chain – help draw 40 milliamps per individual LED under continuous operation. We highly recommend exercising caution when working with high-current components to prevent overheating, which could potentially compromise the structural integrity of the print. As specified within the LD 271 LED datasheet, each unit can withstand up to 100mA direct current flow, though derating curves indicate a need for careful consideration regarding prolonged temperature exposure levels. It's crucial to acknowledge that running these LEDs under such high temperatures would lead to thermal runaway, as evident in instances where excessive heat was detected within one of our PLA-printed prototype units. The main board remains secured within its container via an assortment of screws – originally included with the unit, along with two M3 additional fasteners. Similarly, the enclosure is securely anchored to its holder by a quartet of M3 mounting points.
