Lasers can be used for all sorts of different projects – from vision guidance, to trip wires, and more! These “Crosshair Lasers” are what you might find on a fancy drill press to show where the drill bit will land. This specific laser has an easy to use adjustable focus depending on your distance from the object you wish to project the lines on. This laser has an integrated driver and will simply turn on as soon as 3 – 5VDC are applied.
