A laser card makes it relatively easy to incorporate a laser into a project without hacking a laser pointer to suit one's needs.

Hooking it up

This particular laser card from Sparkfun accepts 3.1 V (+/- 10%), pulling no more than 40 mA. To provide the power, consider either using an on-board Arduino 3.3 volt pin, or a LD1117V33 Voltage Regulator.

Wiring is quite straight-forward. Simply connect the red wire to +3.1V and the white wire to ground. The wires are soldered quite precariously to the back of the card; Sparkfun's laser card mount may be a good investment.
