I'm wondering how I go about using the USB 6008 DAQ in conjuction with labView to turn on and off ths laser:

The laser must be turned on using 3V which isn't possible with this DAQ. I was thinking of usinga BC 109 transistor, then have the laser connected to an external power supply which is supplying 3V to the laser. then have the laser connected to the collector of the transistor.
I set this up and it didn't exactly work out as the laser was drawing to high a current and not working correctly.
Can anyone help me?
