<h3>Design motivations</h3><p>Tropical Seaweed Lamp was born from the desire to recreate a home decorative element that recalled a tropical environment. Thanks to its ascending spiral shape and using a slim E14 LED lamp, it is possible to recreate with a few pennies and a couple of hours of printing an elegant and relaxing lighting effect through this model.</p><p>&nbsp;</p><h3>Modular design</h3><p>Thanks to the modular and print-oriented design, it is possible to print each piece without any support and without plate adhesion supports, leaving the external surface of the model unchanged and perfectly smooth and free of imperfections.</p><p>&nbsp;</p><h3>Necessary tool kit</h3><p>All you need to recreate this lamp is just to indulge yourself with the right colors, a thin E14 LED lamp and an E14 lamp holder.</p>

<h3>Evolution is in color</h3><p>Ring LED RGB is the natural colorful evolution of the Ring LED project. The challenge relating to available space has gone further.</p><p>Not satisfied with the possibility of emitting exclusively white light, I put myself in the shoes of a jeweler who wants to satisfy the most diverse tastes. So where to start from if not from color?</p><p>&nbsp;</p><h3>The model</h3><p>Comfort was necessarily put in the background: to avoid excessively developing the model in length, I opted to exploit the height. The result is still decent in terms of wearability, but there is always room for improvement...</p><p>&nbsp;</p><h3>The hardware</h3><p>In order to have a device that could dynamically change both the color and the effects, the prticipation of a logical mind was necessary.<br>ATTiiny85 was the chosen one: excellent compromise between computational power, consumption and size.<br>I then used a particularly high-performance, robust and convenient WS2812B RGB LED for firmware development due to the open source libraries available online.</p><h3>The assembly</h3><p>Assembly was undoubtedly the most complex part of the project. At first I tried to assemble everything on a hand-made PCB to understand how much space I could take up, but obtaining poor results.</p><p>&nbsp;</p><h3>PCB design </h3><p>The turning point to save space and do as clean a job as possible was undoubtedly the creation of a custom-made PCB.<br>To minimize production costs I preferred to use exclusively THT components, designing the PCB and then soldering the components by hand.<br>With SMD components I would certainly have saved space, but I reserve this practice for a larger project in the future.</p><p>&nbsp;</p><figure class="image"><img src="https://makerworld.bblmw.com/makerworld/draft/550551/2024-02-15_92702468097ba.jpg"></figure><p>Here is the result from the 3D PCB view on the CAD</p><figure class="image"><img src="https://makerworld.bblmw.com/makerworld/draft/550551/2024-02-15_83ba6dec68b98.jpg"></figure><p>And this one is the PCB view </p><p>&nbsp;</p><h3>Hardware&CO</h3><figure class="table"><table><tbody><tr><td>Component</td><td>Quantity</td></tr><tr><td>ATTiny85</td><td>1</td></tr><tr><td>LED RGB WS2812B</td><td>1</td></tr><tr><td>SPDT switch</td><td>1</td></tr><tr><td>Button (NO)</td><td>1</td></tr><tr><td>3.7V 50mAh LiPO Battery</td><td>1</td></tr><tr><td>Resistor 10k</td><td>1</td></tr><tr><td>USB-C (Female) connector</td><td>1</td></tr></tbody></table></figure><h3><br>How it works</h3><p>The RGB LED ring comes to life via an on-off switch. Using the integrated button it is possible to change the color of the diamond, which when pressed repeatedly allows you to go from static colors (adjustable via firmware) to fantastic lighting effects, reaching a final rainbow effect. To recharge the integrated battery, a USB-C connector has been inserted, through which with a special charger, it is possible to completely recharge the device in less than 20 minutes.</p><p>&nbsp;</p><h3>Post processing</h3><p>Although the print came out almost flawless, to give it a more robust and shiny appearance, I applied a resin coating to the device by applying a two-component 3D-Finish product obtaining a beautiful shiny and visibly resistant effect!</p><p>&nbsp;</p><h3>Final result</h3><p><img src="https://makerworld.bblmw.com/makerworld/draft/550551/2024-02-15_95448c3fa9f61.jpg"></p><figure class="image image_resized image-style-side" style="width:54.26%;"><img src="https://makerworld.bblmw.com/makerworld/draft/550551/2024-02-15_9b4cea13c4ce6.jpg"></figure>
