I was thinking of my friend Andy when I modded a Playmates Classic Star Trek Phaser. It was surprisingly quick and easy to do. I wanted something that showed up a little better and was not as dangerous as the Blu-Ray laser phaser mod (not that the Blu-Ray mod isn't very cool).

Step 1: Parts List

You will need:

1. A classic Star Trek phaser - around$25 on eBay.
2. A BlinkM smart LED - made by ThinkM and available from many sources. I got mine from the Maker Shed Store for $12.95
3. An Arduino controller if you do not have one to program the BlinkM. I got the Arduino Diecimila from the Maker Shed Store for $40.

Additional items:

A 2-pin wire connector with leads, like you would find on a PC fan power lead.
Hot glue gun
Soldering Iron
Rosin-core solder
Shrink tubing or electrical tape
You can get blinking LEDs for a buck or so.
Yes, they are cheap and simple. Yoo wouldn't be able to adjust the colors used or the rate of the color cycling.
It looks good but spending $53 to make a flashing LED on a $25 toy seems a bit excessive. Couldn't it have been done using a 555 chip in dual astable multivibrator mode??
Part of the cost comes from the Arduino to program the BlinkM. the BlinkM itself only runs $14 at Makershed.com. Also, this fits entirely in the head of the phaser. A 555 and associated wiring could be done, but you would be locked into the blink rate that you program the 555 to do and the choice of LEDs you use.
now make one you can switch from blue to red!(from stun to kill!!!!!!)
Nice idea! I could modify one of the hatches and extend the pin headers to allow Arduino reprogramming....
