A couple of weeks ago i bought a el-cheapo laser pen. It was cool until it broke the day after I got it. So I decided i would hack it and put it in a LEGO brick...

WARNING: Never shine any laser pointer in your eyes!

Step 1: Gather Materials

Gather Materials

Materials

1. laser pointer or laser pen

2. 2x6 LEGO brick ( or whatever fits your laser assembly )

3. short length of wire

4. batteries that came with the laser

Tools

1. soldering iron

2. solder

3. something to gut LEGO brick

4. something to put a hole in LEGO brick

Step 2: Take the Laser Out of the Pointer or Pen

Take the laser assembly out. You will not need the case so do whatever you want to take it out, just don't brake the laser assembly.

Step 3: Gut the Brick and Put Holes in It

Gut the brick. You might want to use a Dremel but since I don't have one I used my knife. You will have to put two holes in the brick ( one for the laser and one for the button )

Step 4: Put in the Battery Connector

You know when you change the batteries and there is a springy side ( - ) and a flat side ( + ). We need the flat side you can take it out of almost anything there is batteries in. Super glue it in the back of the brick.
