    Default Laser Swamp Effect for $3.00

    This is a laser swamp test that I put together using a green laser pointer that I bought on Ebay for around $2 mixed with a "line" laser lens that I got from a red line laser module (also on Ebay) for 58 cents. in the future I will probably try to see what adding mirrors will do to amplify the effect.
    Please let me know what you think!

    I just received qty 6 tiny power supply modules off Amazon for under $3.00 I'm going to try to match them up to your laser project to keep it small so it will fit in a very small water tight project box.

    That sounds cool! Do you have a link for the power modules? I run mine off from an old computer PS. The 3.3 volt connector seems to make it run a little brighter. Also, I was thinking about adding some mirrors to see what that would do as far as increasing coverage and intensity.

    Very nice effect! Looking forward to seeing more. I also noticed the free (or should have been free) Harbor Freight flashlight in the background

    Nice effect. Just keep in mind that the cheap laser modules only have a short life span, especially when run continuously. OK for a few hours on one Halloween night, but unlikely to last for a month.

    I think it's great. We've been ogling over the swamp effect for years, but have never had a budget that could do anything but look. You now give us hope that our witches' shack may one day be next to a swamp that creeps the kids out even more. Thank you very much.

    Good point David! I will keep you posted as to how long it lasts...I was thinking that a way round this might be to hook it up to a PIR switch. The nice thing about that solution is that the PIR outputs 3.3v so it would be perfect to run the laser!

    Hahaha! Good eye Fogmaster! Yep those things are great and you can't beat the price!

    Thanks Chub! I hope it works out for you guys! On a related note, like David_AVD pointed out; it may burn out quickly (although if I'm honest the laser module I got looks very similar to the Froggy's Fog one). If it does I intend to attach a PIR sensor (less than a buck on ebay or Aliexpress) the wiring for that is really easy: literally 3 wires. And that can be set to let it run for a couple of minutes at a time when it detects movement...that way the laser won't burn out!

    Wow, I love that effect. I've never seen that before.
    How does it work? Is the laser mounted at ground level, shining into the fog? And you don't need the 'spinning mirror' like the Laser Vortex uses?

    Thanks for posting that!
    Stamp out the Christmas Creep !
