Spiral RGB LED Lamp

prusaprinters

<p>A beautiful desk lamp using an RGB LED strip and an ESP8266 controller. No coding required!</p><p>Cost is $70 once you factor in what you'll use, more up front for the spools of filament. For parts I used, see the table and links below. I followed <a href="https://www.youtube.com/watch?v=GYxctjukehY">this youtube video</a> by Core Electronics for the LED strip part. You can control it over WiFi via WLED, which is awesome. The strip is glued to the inner support pole, and I did some measuring with a string to get the angle and length exactly right.</p><figure class="table"><table><thead><tr><th style="height:40.3333px;">Part</th><th style="height:40.3333px;">Quantity</th><th style="height:40.3333px;">Cost</th><th style="height:40.3333px;">Total Cost</th></tr></thead><tbody><tr><td style="height:40px;"><a href="https://atomicfilament.com/collections/opaque-pla-filaments-1/products/bright-white-pla-filament">Bright White PLA</a> Filament (1 Kg)</td><td style="height:40px;text-align:right;">0.153</td><td style="height:40px;text-align:right;">$29.99</td><td style="height:40px;text-align:right;">$4.59</td></tr><tr><td style="height:40px;"><a href="https://atomicfilament.com/products/crystal-clear-natural-petg-pro?_pos=1&amp;_sid=ad49fde26&amp;_ss=r&amp;variant=11046086145">Crystal Clear / Natural PETG</a> PRO (1 Kg)</td><td style="height:40px;text-align:right;">0.344</td><td style="height:40px;text-align:right;">$32.99</td><td style="height:40px;text-align:right;">$11.35</td></tr><tr><td style="height:40px;"><a href="https://www.adafruit.com/product/276">5V 2A (2000mA) switching power supply</a></td><td style="height:40px;text-align:right;">1</td><td style="height:40px;text-align:right;">$7.95</td><td style="height:40px;text-align:right;">$7.95</td></tr><tr><td style="height:40px;"><a href="https://www.adafruit.com/product/368">Female DC Power adapter</a> -&nbsp;<br>2.1mm jack to screw terminal block</td><td style="height:40px;text-align:right;">1</td><td style="height:40px;text-align:right;">$2.00</td><td style="height:40px;text-align:right;">$2.00</td></tr><tr><td style="height:40px;"><a href="https://www.adafruit.com/product/2821">Adafruit Feather HUZZAH with ESP8266</a> -&nbsp;<br>Loose Headers</td><td style="height:40px;text-align:right;">1</td><td style="height:40px;text-align:right;">$16.95</td><td style="height:40px;text-align:right;">$16.95</td></tr><tr><td style="height:40px;"><a href="https://www.adafruit.com/product/1138?length=1">Adafruit NeoPixel Digital RGB LED Strip</a> -&nbsp;<br>White 60 LED - WHITE (1 meter)</td><td style="height:40px;text-align:right;">1</td><td style="height:40px;text-align:right;">$24.95</td><td style="height:40px;text-align:right;">$24.95</td></tr><tr><td style="height:40px;"><a href="https://www.adafruit.com/product/4783">Universal Proto-board PCBs</a>&nbsp;<br>2cm x 8cm - 3 Pack</td><td style="height:40px;text-align:right;">0.166</td><td style="height:40px;text-align:right;">$2.25</td><td style="height:40px;text-align:right;">$0.37</td></tr><tr><td style="height:20px;"><a href="https://www.adafruit.com/product/1886">Solder</a></td><td style="height:20px;text-align:right;">0.01</td><td style="height:20px;text-align:right;">$7.95</td><td style="height:20px;text-align:right;">$0.08</td></tr><tr><td style="height:20px;"><a href="https://www.adafruit.com/product/1311">Wire</a></td><td style="height:20px;text-align:right;">0.01</td><td style="height:20px;text-align:right;">$15.95</td><td style="height:20px;text-align:right;">$0.16</td></tr><tr><td style="height:40px;"><a href="https://www.amazon.com/Gorilla-105795-Super-1-Pack-Clear/dp/B08QQZ71CV/">Super Glue</a></td><td style="height:40px;text-align:right;">0.25</td><td style="height:40px;text-align:right;">$8.66</td><td style="height:40px;text-align:right;">$2.17</td></tr></tbody></table></figure><p>I made it somewhat modular so you could make them taller or shorter. The outer pieces are printed in vase mode and just glued together.</p><p>I used a 0.8mm nozzle for the outer transparent parts for some additional speed and rigidity.</p>
