Lantern LED on Barrel

thingiverse

I created a unique barrel that houses a switch, battery, and wiring to light an LED inside an old mining lantern. This project was designed to add atmosphere to the board game Shadows of Brimstone, but it can be used for any purpose. I used 3D printing to create the model, which allowed me to design intricate details and shapes. The barrel is made from a single piece of plastic, with a small compartment in the bottom for the battery holder. The switch is located on one side of the barrel, and the wiring runs through a small hole at the top. I used a 3D printer to create the model, which allowed me to design intricate details and shapes. To assemble the lantern, I started by inserting the LED into the base of the lantern. I applied a small amount of superglue to the bottom plastic edge and inserted the LED through the top hole. I waited for the glue to dry before moving on to the next step. Next, I assembled the glass globe, top, and topcap using superglue. I made sure that the top and base were aligned properly, so that the handle inserts lined up correctly. I also applied a small amount of hot glue to secure the lantern bottom to the barrel top. I used a resistor in my build, but it may not be necessary for all LED lights. The 2.2v LED I used worked well with a 3 volt battery, and was actually brighter than with a resistor. However, I will have to see if this affects the life of the LED in the long run. To solder the wires to the switch and battery holder, I used shrink tubing to prevent shorts. I placed a small piece of shrink tubing over the wire going to the positive battery post, and then soldered the positive battery wire to the 1st blue wire on the switch. I pulled the shrink tubing over the solder joint and carefully used a heat gun to shrink it. Next, I pushed the remaining wires through the bottom hole in the barrel top, and then soldered the long positive LED lead to the positive lead from the barrel. I did the same for the negative lead, using shrink tubing again to keep the leads from shorting. Before gluing everything together, I tested the switch to make sure it turned on the LED. If it didn't work, I checked the battery polarity and made sure the LED wasn't reversed. Finally, I glued the lid and lantern together using superglue. I applied some hot glue to secure the wires inside the barrel, and then placed the lid in place. I held the lid for 20 seconds to make sure it stuck properly. The finished lantern looks amazing, with a warm glow from the LED light. It's perfect for adding atmosphere to a game or display, and can be used in a variety of settings.
