Project homepage: https://github.com/jonnor/projects/tree/master/lighting#pentagonia Pentagonia: A flower-like lamp with intricately shaped petals cut from laser-cut aluminium foil. Three hours of testing confirmed that this design can handle high temperatures. A 1-watt LED ran smoothly at 350 milliamps in a 24-degree ambient temperature environment. The cardboard behind the LED reached 45 degrees, and the LED module itself reached 60 degrees - both perfectly safe results. Important Safety Note: Using a 3-watt LED without proper testing could be hazardous. Materials Needed Cardboard or similar bendable materials Aluminium foil with shiny side up Wire or yarn for securing the LED LED module for bright illumination Instructions to Make Your Own Pentagonia Lamp Take cardboard, either corrugated or thin plastic sheets like PP or PE. They will work just fine. Glue aluminium foil to your chosen material, making sure the shiny side is facing upwards. This can be done with regular paper glue without any issues. Next Steps: Lasercut and Assembly Cut through the slits between the petals of the aluminium foil using a laser cutter. Bend the pentagon's petals upwards carefully. Thread some wire or yarn through the holes on each petal to secure it in place. Insert your LED module into the reflector, securing it with wires. You can also 3D print this design if you use flexible filaments or make sure the edges are thin enough for easy bending.
