Introduction: Rocket Night Lamp

By
About: Hobbyist in woodwork and electronics.

A simple 3D printed night lamp with basic electronics.

Supplies

For this project you will need:

  • CR2032 battery
  • CR2032 battery holder
  • M3x10mm screw
  • 3mm white LED
  • Microswitch 2 positions
  • 180 ohms resistor
  • Solder iron
  • 3D printer

Step 1: Print the Case

This step is pretty straightforward: just print the box in the color you want. I printed the difuser white, but you can test other colors.


No meticulous parameters are necessary, I used 0.32mm layer.

Step 2: Bending the Pins

This circuit uses a 180 ohms resistor to limit the current. The two leds are in paralel.

Bend the pins and solder in the way showed in the pictures:

1 - bend the longer leg to make it inclined

2 - bend the head of the led to make it perpendicular

3 - make a "U" format in the shorter pin.

4 - in the end, the two leds must be in a triangle shape

Step 3: Soldering the Pins

Be sure to solder the pins the way it is showed in the image.

If cathode and anode are inverted, it won't work.

Step 4: Glue Everything and Close the Box

Test the leds before closing.

Step 5: Enjoy!

PS.: The pink and red look almost the same in the dark.
