# 3D Printed Camera LED Ring ## Overview http://www.youtube.com/watch?v=sbKjKKVewDU ![](https://cdn-learn.adafruit.com/assets/assets/000/013/807/medium800/3d_printing_neopixel-ring-case.jpg?1390786881) ## DIY LED Ring Light Trying to get those pixel perfect macro shots on a budget? Build your own DIY low cost ring of light with a NeoPixel Ring and Trinket, Adafruit tiny arduino micro controller. The color and brightness of the LEDs can be programmed to color or pattern! ![](https://cdn-learn.adafruit.com/assets/assets/000/013/802/medium800/3d_printing_parts.jpg?1390774499) ## Prerequisite Guide: - [NeoPixel UberGuide](https://learn.adafruit.com/adafruit-neopixel-uberguide "Link: https://learn.adafruit.com/adafruit-neopixel-uberguide") - [Introducing Trinket](https://learn.adafruit.com/introducing-trinket "Link: https://learn.adafruit.com/introducing-trinket") ## Parts List: - [24 NeoPixel Ring](http://www.adafruit.com/products/1586 "Link: http://www.adafruit.com/products/1586") - [Lithium ion Polymer Battery 500](http://www.adafruit.com/products/1578 "Link: http://www.adafruit.com/products/1578") - [JST Battery Extension](http://www.adafruit.com/products/1131 "Link: http://www.adafruit.com/products/1131") - [Adafruit 5V Trinket](http://www.adafruit.com/products/1501) - [Slide Switch](http://www.adafruit.com/products/805) ## Tools & Supplies - [Soldering Iron](http://www.adafruit.com/category/8_84) - [60/40 rosin-core solder](http://www.adafruit.com/products/145) - [30 gauge wire wrap](http://www.adafruit.com/products/1446 "Link: http://www.adafruit.com/products/1446") - [Wire Cutter/Strippers](http://www.adafruit.com/products/527 "Link: http://www.adafruit.com/products/527") ![](https://cdn-learn.adafruit.com/assets/assets/000/013/806/medium800/3d_printing_eye.jpg?1390786854) ## Photography Lighting Using the 24x NeoPixel ring as a light ring is a great way to enhance macro-photography. A ring of light provides a spot-light effect, removing shadows caused by the camera getting in front of the subject. In our test shots above the NeoPixel ring projects a ring of light inside the eye. # 3D Printed Camera LED Ring ## 3D Printing ![](https://cdn-learn.adafruit.com/assets/assets/000/013/803/medium800/3d_printing_3d-parts.jpg?1390776241) [Download STLs](http://www.thingiverse.com/thing:235242) ## Transparent PLA Print the LED cover to soften and diffuse the NeoPixel ring. For most FDM 3D printers, PLA material works with out a heated bed. The extruder should be set to 230c. The model was design to print with out a raft or supports. Below is a small list of places to get PLA. Make sure your filaments diameter size matches your 3d printer. Most common size is 1.75mm and 3mm. - [Inventibles](https://www.inventables.com/categories/materials/3d-printer-filament) - [Makerbot](http://store.makerbot.com/pla-filament) - [Ultimachine](https://ultimachine.com/catalog/print-materials/pla/pla-175mm) - [Amazon](http://www.amazon.com/s/ref=sr_nr_n_1?rh=n%3A6066128011%2Ck%3Apla+filament+1.75&keywords=pla+filament+1.75&ie=UTF8&qid=1389803195&rnid=2941120011) - [3D Printer Ninja](http://3dprinterninja.com/3d-printer-filament/) # 3D Printed Camera LED Ring ## Circuit Diagram ![](https://cdn-learn.adafruit.com/assets/assets/000/021/687/medium800/3d_printing_cam-light-rig-Curcuit-Layout.jpg?1418346829) ![](https://cdn-learn.adafruit.com/assets/assets/000/015/848/medium800/3d_printing_60camRing-Diagram.jpg?1397743219) ## Prototyping Circuit Please be sure to check out [NeoPixel Guide](http://learn.adafruit.com/adafruit-neopixel-uberguide "Link: http://learn.adafruit.com/adafruit-neopixel-uberguide") to get a better understanding of how to power and work with NeoPixels. Use a bread board and alligator clips to connect the components together. You will want to solder header pins onto the 5V Trinket for a secure connection when prototyping on a breadboard. - **GND** NeoPixel Ring connects to **GND** on 5V Trinket - **IN**  NeoPixel Ring connects to **GIO#0** - **PWR** NeoPixel connects to **5V** - **Pin 1** Slide Switch connects to **BAT** on 5V Trinket - **Pin 2** Slide Switch connects to **Positive** wire of JST Extender - **Negative** wire of JST Extender connects to **GND** on 5V Trinket ## Programming Trinket Please check out the [NeoPixel Arduino Library guide](http://learn.adafruit.com/adafruit-neopixel-uberguide/arduino-library) to get a better understanding on how to program your own colors and animations. ```auto #include #define N_PIXELS 24 // Number of pixels you are using #define LED_PIN 0 // NeoPixel LED strand is connected to GPIO #0 / D0 Adafruit_NeoPixel strip = Adafruit_NeoPixel(N_PIXELS, LED_PIN, NEO_GRB + NEO_KHZ800); void setup() { strip.begin(); // you can change the brightness to lower if its too bright! strip.setBrightness(255); // Set LED brightness 0-255 colorWipe(strip.Color(255, 255, 255),0); // fill the strip with all white strip.show(); // Update strip } void loop() { } // Fill the dots one after the other with a color void colorWipe(uint32_t c, uint8_t wait) { for(uint16_t i=0; i
