Hi, I have NEVER made a laser before! Infact I havent made meny technical things before for that matter, but what I wanted to do is make a violet laser. I have a 5mW green laser, a 100mW green laser and a 300mW red. But I have always wanted a blue one and violet is close enufe! Anyway some bloke on eBay is selling a 150mW violet diode and he has put it in a housing (Axixz housing probley 
) anyway he was talking about a drive, but I have no idea were to get one. So im just gonna use a resistor. Now im using a 9V battery as sourse voltage. I need 5V for forward voltage and 90mA for forward current. So if im correct, a 47 ohm resister is required. I am also going to add a capacitor(some how :
) And of corse a switch (duh). Can I do this? and how long will it last? And how could I make it, as I dont really know how to add a capacitor to the circut as I have never done it ! So yea, how long will it last, is it worth it and how do I do it?
