Hi all first post and very new to electronics and quite high aspirations. Please bear with me.
I have a little understanding of the way electrons move i think, however i haven't built many circuits and i thought this forum might be the place to start.
The first project i would like to accomplish is a laser trigger for high speed flash photography.
I just need to build a circuit to power the laser which will provide 40-50mA @ 2.4-2.8 volts. This in turn with a photon resistor,arduino and an opto isolator triggering my flash-head should do the trick.
I have a 3.3-12v power supply @ 2.54A, and a LM317T adj voltage regulator.
I have searched and tried to work out the formula as best i could but without a better understanding of electronics i am at a loss.
I can trigger my flash with my arduino safely but i need to work out the circuit for the laser without spending too much.
Here is the link to the laser diode i intend to use.....

If there is a thread which will help me please link it.
Sorry for the essay but many,many thanks in advance.
