If you're curious about the nuts and bolts behind the phaser construction from this week's episode of The Escapist Show, you've come to the right place. Here you'll find a list of all the materials you'll need for the project, as well as step-by-step instructions. Please remember to follow all necessary safety precautions and don't use your phaser to rob a bank, or anything.

Let's start with a list of the items you'll need.


  • Star Trek toy phaser (www.thinkgeek.com)
  • Laser diode module (www.laserdiy.com)
  • Laser driver circuit (www.laserdiy.com)
  • 4Ω(Ohm) resistor (www.laserdiy.com, www.digikey.com)
  • Single channel optoisolator (www.sparkfun.com , www.digikey.com)
  • 3v coin cell battery w/ holder (Radio Shack #2032)
  • Wire
  • Solder


  • Dremel
  • Soldering iron with temperature control
  • Multimeter
  • Screwdrivers
  • Wire strippers/cutters
  • Sturdy razor or utility knife
  • Non-conductive glue (cyanoacrylate recommended)

Safety Equipment:

  • Safety glasses, for use with power tools
  • Safety goggles, for use with lasers (must block the specific frequency of your laser, and should cover your peripheral vision, too)
    (Note: I used welding goggles with a special plate. They function both as safety glasses, and very effective laser protection.)

Now that you've got the equipment you'll need, let's move on to the actual construction.
