Fran 🇦🇷<p>Some ideas behind the design of this lamp:</p><p>- It can be shipped disassembled in a small volume package and then reassembled by the user without any tools.</p><p>- The wiring and power supply can be easily replaced with common parts that can be found anywhere.</p><p>- Easy to disassemble at the end of the product's life and most parts are compostable, reusable or recyclable.</p><p>🧵 <a href="https://mastodon.online/tags/PalitoLamp3" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>PalitoLamp3</span></a> <a href="https://mastodon.online/tags/lamp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>lamp</span></a> <a href="https://mastodon.online/tags/LED" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>LED</span></a> <a href="https://mastodon.online/tags/wood" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>wood</span></a> <a href="https://mastodon.online/tags/design" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>design</span></a> <a href="https://mastodon.online/tags/maker" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>maker</span></a></p>
Fran 🇦🇷<p>Palito Lamp 3.0 is ready!</p><p>- Better energy efficiency thanks to 20V USB PD-based circuit. About 1.8W / 150 lumens on LOW and 5.5W / 500 lumens on HIGH.</p><p>- Improved stability with a heavier base and a vertical rod that doesn't shift the center of gravity horizontally when adjusting the height.</p><p>Anyway, beyond the functional improvements, I haven't really fallen in love with the resulting aesthetics, so... keep trying! 🤷‍♂️😁</p><p>🧵 <a href="https://mastodon.online/tags/PalitoLamp3" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>PalitoLamp3</span></a> <a href="https://mastodon.online/tags/lamp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>lamp</span></a> <a href="https://mastodon.online/tags/LED" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>LED</span></a> <a href="https://mastodon.online/tags/electronics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>electronics</span></a> <a href="https://mastodon.online/tags/lighting" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>lighting</span></a> <a href="https://mastodon.online/tags/design" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>design</span></a> <a href="https://mastodon.online/tags/maker" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>maker</span></a> <a href="https://mastodon.online/tags/argentina" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>argentina</span></a></p>
Fran 🇦🇷<p>The LED drivers I ordered from China finally arrived (the one in the previous photos got burned by ESD 🤨), and I was able to complete the circuit of the prototype.</p><p>The black board is a USB-PD trigger board that I use to get 20V from the USB charger.</p><p>And the green board is a constant current LED driver that regulates the LED current to 300mA at the full brightness position of the switch, and to about 80mA at the low brightness position.</p><p>Questions?</p><p>🧵 <a href="https://mastodon.online/tags/PalitoLamp3" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>PalitoLamp3</span></a> <a href="https://mastodon.online/tags/lamp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>lamp</span></a> <a href="https://mastodon.online/tags/LED" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>LED</span></a> <a href="https://mastodon.online/tags/electronics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>electronics</span></a> <a href="https://mastodon.online/tags/maker" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>maker</span></a></p>
Fran 🇦🇷<p>First time working with a CAD software ⚠️😬. Making a 3D model with FreeCAD for CNC-cutting the head of the lamp.</p><p>🧵 <a href="https://mastodon.online/tags/PalitoLamp3" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>PalitoLamp3</span></a> <a href="https://mastodon.online/tags/lamp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>lamp</span></a> <a href="https://mastodon.online/tags/CAD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>CAD</span></a> <a href="https://mastodon.online/tags/FreeCAD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>FreeCAD</span></a></p>
Fran 🇦🇷<p>To simplify the shape, I decided to remove the difference in thickness between the LED area and the circuit area. The problem now is that a deeper hole for the LED reduces the angle of the light beam.</p><p>In version 2, the wood around the LED was 8mm thick, but the switch alone is already that thick. So, I managed to fit all the electronics in 12mm height; that will reduce the light beam coverage a bit, but sometimes in life you have to make compromises 🤷‍♂️.</p><p>🧵 <a href="https://mastodon.online/tags/PalitoLamp3" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>PalitoLamp3</span></a> <a href="https://mastodon.online/tags/lamp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>lamp</span></a> <a href="https://mastodon.online/tags/woodworking" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>woodworking</span></a> <a href="https://mastodon.online/tags/LED" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>LED</span></a></p>
Fran 🇦🇷<p>I started to prototype the third version of the Palito lamp. The goals this time are:</p><p>- Make it run cooler using more efficient 20V USB-PD based circuits.</p><p>- Go back to a vertical rod design.</p><p>- Simplify the shape of the lamp head and make it less bulky.</p><p>- Improve the smoothness of the head height adjustment.</p><p>- Reduce the area of the desk that the lamp uses.</p><p>- Remove some unexpected glare in the previous version caused by the bottom heat sink.</p><p>🧵 <a href="https://mastodon.online/tags/PalitoLamp3" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>PalitoLamp3</span></a> <a href="https://mastodon.online/tags/lamp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>lamp</span></a> <a href="https://mastodon.online/tags/design" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>design</span></a> <a href="https://mastodon.online/tags/lighting" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>lighting</span></a></p>
