Step 1: The Problem

When I was studying it was difficult to me to see clearly what I was highlighting.

Warm lights and Neon lights are poor of UV light and highlighters need them to glow bright.

Step 2: Design

I designed the file on Solidworks but you can find the STL ready to print here: https://www.thingiverse.com/thing:2800267

Step 3: 3D Print

Just Do it :)

Step 4: What You Will Need

Here is what you will need:

  • 2x 100Ohm Resistors
  • 2 x Violet Leds (round 5mm)
  • printed piece
  • Wire solder
  • USB cable
  • hot glue

Step 5: Led

Mount the leds into the holes of the lamp, then solder the resistor in series to the positive anode of the leds.

Step 6: USB

Peel the USB cable and cut of the other wires, in order to have only the red and black.
Then solder the red (positive) to the anodes of the two leds in parallel (those with the resistors) and the black one to the cathodes (negative).

Step 7: I Used Glue

I used glue to keep everything fixed in place but if you prefer you can do something better, anyway it's only a prototype.

Step 8: That's It

There is a HUGE difference to before and after.

    Cool tutorial. It might be a good idea to put a warning in about looking directly at UV light globes, or using them in direct line of sight. Even the UV bouncing off the paper can be harmful to the eyes.
