<h3>RainbowLamp</h3><p>3D model for a RGB color changing LED lamp. <img src="https://github.com/SuperIlu/RainbowLamp/raw/main/doc/two_lamps.jpg" alt="two lamps"></p><p>&nbsp;</p><p>3D model</p><p>The 3D model was created using <a href="https://www.rs-online.com/designspark/mechanical-software">DesignSpark Mechanical</a>. The source files as well as STLs are included. You need to print one of each piece:</p><ul><li><strong>v2_rbl04</strong>: the lamp arc</li><li><strong>v2_box03</strong>: the base and battery holder</li><li><strong>v2_bottom02</strong>: a lid for the battery holder (in my print it stays on just with press fit)</li></ul><h3>&nbsp;</h3><h3>Printing Parameters</h3><p>I printed my version with white SuperPLA (215C nozzle, 70C bed), 20% infill, brim active and supports everywhere. The surface orientation was as shown below. <img src="https://github.com/SuperIlu/RainbowLamp/raw/main/doc/print_param.png" alt="prusa slicer screenshot"></p><p>&nbsp;</p><p>Other parts</p><p>You will also need:</p><ul><li>7 RBG color changing LEDs (I used LEDs from <a href="https://shop.blinkyparts.com/en/detail/76374904542142cbb9d4bba147246f99">blinkyparts</a>)</li><li>A battery holder (I used a double AA one as shown below)</li><li>2x M3x6mm screws</li><li>2x M3 nuts</li></ul><h3>&nbsp;</h3><h3>Assembly</h3><p><img src="https://github.com/SuperIlu/RainbowLamp/raw/main/doc/assembly.jpg" alt="picture of a partly assembled lamp"></p><p>The arc can be attached to the base on both ends. This way you can e.g. form a half circle or use an arc on both ends of a bookshelf.</p><ul><li>clean the printed parts (I used a knife and a small screwdriver)</li><li>put in the LEDs with the longer wire on the outside of the arc</li><li>start bending the wires from the farthest LED in the direction of the end where you want to attach the base</li><li>repeat for all LEDs</li><li>the wires should be barely long enough to build up a solder chain as shown on the picture</li><li>shorten the wires of the LED at the base ~5mm</li><li>puth the wires of the battery holder through the middle hole in the base</li><li>solder the red wire to the LED wire on the outside of the arc</li><li>solder the black wire to the LED in the inside of the arc</li><li>puth the nuts into the holes in the arc and attach the base with the M3x6 screws</li><li>put in some AA cells to test if everything works</li><li>optional: put some hot glue on the back pf the LEDs to make sure that stay in place (please ignore the butchering in my picture, my gun failed)</li></ul><p><img src="https://github.com/SuperIlu/RainbowLamp/raw/main/doc/assembled_glued.jpg" alt="picture of a partly assembled lamp"></p><h3>&nbsp;</h3><h3>License</h3><p>The contents of this repository is licensed under <a href="https://creativecommons.org/licenses/by-sa/4.0/">CC BY-SA 4.0</a>, see LICENSE.md for details. <img src="https://camo.githubusercontent.com/0df8fd3e955d97ae69dedfa2568fb2dd4186cd60917ca40aefabb7466d5b46ce/68747470733a2f2f692e6372656174697665636f6d6d6f6e732e6f72672f6c2f62792d73612f342e302f38387833312e706e67" alt="Creative Commons License"></p><h3>&nbsp;</h3><h3>Contact</h3><p>You can find me on <a href="https://twitter.com/dec_hl">Twitter</a> if you want...</p>
