Blu-Ray LASER Pointer for Less Than 15GBP Glow Crazy Game Mod




Buy a children's game called 'Glow Crazy' from Amazon or the like. There are other versions of this game but be aware some light pens are L.E.D and not a LASER.

Step 1: Take the LASER Pen...

Remove the screws from the pen and prize open with a flat object.

Step 2: Disassemble and De-solder

Break the pen down. Notice the pot adjuster is set to almost nothing? Don't crank it up yet and use it as the LASER module is mounted in plastic and has no heat-sink!

Step 3: Remove Module From the Driver

You need something sharp to pick the plastic resin that secures the LASER module to the driver PCB, I used a pair of tweezers.
Once free quickly de-solder the module using a low wattage iron and solder mop.

Step 4: Make the Pointer

There are many ways to mount this so I won't go into that.

I decided to keep the existing lens as it focuses nicely once removed from the casing.

I leveled off the plastic around the bottom of the laser module, applied some Arctic Silver thermal compound and attached it to a PC heat sink.

I used a 3.7volt 1800Ma cell from an old laptop battery to power the driver board that I reconnected to the LASER with wires.

Happy Modding!

    All of these notes are good information. You should edit your project and include all this detail.

    I understand that sometimes you might have to rely on an external image source to convey your intention, but referenced images should be cited (sometimes our community gets excited about copyright/etiquette on things like that)

    Note: In the bottom left picture 'T1 ll T2' at the top of the PCB is where the LASER diode negative (-VE) lead mount is. The (+LD) is on the opposite side.

    Just to clarify, this picture was taken from Google to most accurately represent the resulting LASER beam. If anything this image understates the end result.

    I was unable to take a good enough picture of my projects beam and the camera in my phone is not good enough in the dark.
