I decided that, although cool, there was something lacking. I just got a whack of little laser diodes in da mail, so it was just a matter of time before everything had lasers attached; arduino projects, flashlights, the baby... (I cannot condone the use of lasers on small humans, in fact all my children are too big to accessorize in that fashion)

Adding a laser seems like big medicine, however in actuality, it is super easy. All I needed was power and a switch (cause ya don't want it to be on all the time). The units I got were rated at 5V. Easy peasey cause I already gots 5V coming off the arduino. A tactile momentary switch and BOOM, thar she be.
