Raspberry Pi Camera Case Back for 6x 5mm LEDs

thingiverse

This is a new back cover for the Raspberry Pi camera case (from http://www.thingiverse.com/thing:92208) which enables six 5mm LEDs to be attached to the camera for illumination. Excellent for using with IR LEDs and the Pi NoIR camera for monitoring in darkness. The build showcased in the photos utilizes the following components: This back cover model. The front cover CameraFrontBottom-fingers.stl file from: http://www.thingiverse.com/thing:403712 Two links, link.stl, from: http://www.thingiverse.com/thing:247590 The fingerclip base, fingerclip.stl, from:http://www.thingiverse.com/thing:403712 The LEDs shown are six high-power IR LEDs: https://www.adafruit.com/product/387 As illustrated, the LEDs are designed to be driven by five volts and wired as two independent sets of three LEDs in series. The anode (longer leg) of a LED is directly soldered to the adjacent LED cathode (shorter leg). A five-volt voltage source (like from the Raspberry Pi 5V output) is applied to the anode of the top LED and a twenty-four-ohm, one-quarter-watt resistor is soldered in series from the cathode of the bottom LED down to ground. This will drive each set of three LEDs with about ~30-50mA of current for a total of ~60-100mA for both sets. Do not omit the resistors! You can increase the resistance value to lower the current and dim the LEDs, but be cautious when decreasing the resistance as it may draw more current and potentially damage the Pi or burn out the resistors.

Use a file if the holes are too small, or adjust the source model in Tinkercad:https://www.tinkercad.com/things/3aMExisYZmM?display=7yBckVlmHwc
