Game Boy LED DIY

Introduction: Game Boy LED DIY

About: I enjoying learning new skills and love working with my hands. I often revisit my childhood and create projects from things which I once cherished. I've learned a variety of modifications for Game Boys and a...

  • Tri-wing screwdriver
  • Soldering Iron/solder
  • 3mm LEDs (diffuse)
  • 2K ohm resistor
  • Solder wick


Open your Game Boy by removing the 6 tri-wing screws on the back panel. Also remove the Phillips head screws connecting the front PCB to the front shell. Separate the two units and locate the LED. Use a solder wick to remove the solder around the led leads. Remove the LED.

Step 1: Replace Existing Resistor

You will need to replace the "R1" resistor located near the top of the PCB. Use your soldering wick again to remove the excess solder on the front of the PCB. Replace this resistor with a 2K-3K ohm resistor to reduce the brightness of the LED. Otherwise it would be much too bright. Solder the LED and the resistor in place and you are off to the races. Close her up and enjoy.

    Or you could replace the appropriate resistor already in series with the led on the pcb. No need to add another to the leg of the LED.
    Solder sucker's quite literally suck. Desolder braid is much more effective.
    Calculate the required resistor value (Google the formula or find one of the many calcs on the web 3v drop is a good ballpark for most LED).
    May as well learn to do things properly that way you can pass on more powerful knowledge to any fledgling modders out there.

    Agreed. Updated. Wonder why in the world I didn't do that before... Thanks for improving this instructable.

    What is the recommended voltage of the LED? Or does it matter if you include a resistor?

    It is about 3V for all colors. Higher wavelength LEDs have a lower recommended voltage so make sure to use the resistor.
