    A 600nm emitting semiconductor laser for only 5$?!

    Ya i was just referring to the NATO standard round. The first link that came up kinda referred to the ar15 and m4 loosely and interchangeably. And I realize the pressure will vary between rifles and barrels and there's a million different things that influence the pressure and velocity. I just...

    Outstanding laser art

    Will my tank glass be safe?

    I would say shine it thru the top thru the water (wear eye protection) Even if its only a watt or 2 its going to heat up a small spot of glass much quicker than the rest of the surrounding glass with liquid cooling one side of the glass. It might not crack normally but water is about 8...

    Sharp GH04955A2G/ The New 495nm diodes

    Uhh i can hook up a medicine bottle that has that size set screw but ive misplaced my calipers so if he doesnt have a pair it might be a bit of a guessing game digging through a mixed skittles m&ms bag of assorted screws to find. And just so everyone here is in the know.... america makes the...

    473nm pointer questions

    While i agree its possible it could be a scam i checked the sellers other items and they have single WL 473nm handhelds for sale and also 445nm and 405nm units listed and all of the listings have fairly appropriate corresponding prices. Thus the reason i think it could be a legitimate buy as the...
