    Will my Arctic Spyder III make it through customs? ( Canada )

    how to wire multiple diodes to one driver?

    Putting laser diodes in series is the best option. If you run them in parallel you need resistors in series with each diode to limit the current, without the resistors you run the risk of one diode drawing more current than the others. In series they need (num diodes)*(voltage drop per diode)...

    How would you react if the reputation system is removed on LPF?

    There are a lot of PM's and reported posts behind the scenes of people crying foul, saying it's against the rules to leave neg rep (I wish I was joking) among other things. It's definitely not clear to people how the system can be used. If it stays there needs to be an agreement on it, and...
