( i am in india). 1 of teh problems however has been that I always ended up getting line lasers.... I think I will make a 3D scanner instead HI

Here are your answers :P ... 1)indeed the laser diode has 3 pins(GND,LD,Photodiode or N/A) but on the schematic it have only 2 pins (GND(cathode) and LD(anode,where you wire +)). You can read more about this from : http://www.repairfaq.org/sam/laserdio.htm ---- 2)the 3 position switch description ... position A ... the pushbutton is bypassed so the circuit is always ON. position B ... the circuit pass through the pushbutton so the circuit is ON only when you push the pushbutton position C ... circuit is OFF all the time because the + supply is unconnected to the circuit. Hope this helps Sorin Hi,
