• Hi.

    Theoretically speaking: There is supposed to be content here, so here is a picture of a mantis shrimp getting ready to ruin your day.

    Seriously, look at those eyes. Thats what I call a game face.

      I likely broke something.

      Assuming you can't see the mantis shrimp... I did something wrong.

      I'd like to see the Big shrimp and nothing else. The forum headline feed on the home page is distracting and looks a little messy. Shrimps for the win!

    Most likely a better solution for laser driven video projectors would be to use a DLP device rather than a raster scanner.

    Neat. Thank you, didn't expect to get away so easily.

    Well I kind of didn't, just realised Arduino's analog out is only 8 bit, will need to find a better mincrocontroller.

    how to tell if lens is AR coated or not?

    Is there an easy way to tell? I can scratch the edges if there's a procedure involving that. This is a general question I fell I should know, not just laser collimator lenses.

    Hey thanks. Much appreciated, , looks simple enough.
    That said I don't have a +-5V PSU. Any chance a +-12V PSU can be used? Maybe even the one powering the scanner drivers?
