Neopixel Ring Articulating Mount

prusaprinters

<p>What’s better than Adafruit’s individually addressable smart RGB LEDs – an articulating mount to house them! This assembly is designed to hold the 12 LED RGB(W) NeoPixel Ring (e.g. Product ID:2853; <a href="https://www.adafruit.com/product/2853">https://www.adafruit.com/product/2853</a>). The dimensions of the ring are: 3.68mm (O.D.) x 23.3mm (I.D.) x 325mm and the board fits in snuggly.</p> <p>The components have holes for 3mm screws and will need to be threaded with the appropriate sized tap. The ball joint can accommodate a 30 mm screw with a nyloc nut instead of individual screws.</p> <p>I have added a diffuser that snaps on top of the LED mount. It is preferable to print the part in a translucent clear material, e.g. PETG with supports enabled.</p> <p>The NeoPixel mounts were designed to fit into a miniature photo studio</p> <p>--- See <a href="https://github.com/electronlove/MiniStudio">https://github.com/electronlove/MiniStudio</a> for info and <a href="https://youtu.be/95q27Tv82Dc">https://youtu.be/95q27Tv82Dc</a> ---</p> <p>The mini studio has not been uploaded to Thingiverse yet but any sturdy box will do !</p> <p>The NeoPixels are controlled by a Raspberry Pi - and a flask-based web server for a RGB color picker to control the NeoPixels.</p> <p>See <a href="https://github.com/uozuAho/pilights">https://github.com/uozuAho/pilights</a> for flask app to control LEDS.</p> <p>Code has been modified to run with Adafruit Neopixel Rings and run as systemd process at startup.

The ball joint should be re-oriented with the flat face down. </p> Note: I printed the NeoPixel LED holder in ABS which required scaling in Cura to 104% (ABS shrinks!). <p>I am driving the NeoPixels with a Raspberry Pi so I through together a Perma-Proto HAT with a 74AHCT125 Quad level shifter. I also added breakouts for I2C, SPI, and serial communication for some light sensors.</p> <h3>Post-Printing</h3> <p><strong>Preparing the Mounting Holes</strong></p> <p>The screw holes are 3 mm and should be tapped with the appropriate size for best results. There should be some play in the joint to allow for positioning.</p> </div></p></p> Category: Electronics
