    New Earthquake Proof Bed May Actually Be A Terrible Idea

    You guys know you can make pure oxygen from yeast and peroxide might be worth figuring out a way to do it and fill empty old small cylinders that have a pressure gage with pure O2. You never know when you'll need to hold your breath for a few mins and you can hold it better with pure oxygen.

    Well this is different

    Great more fear mongering about lasers being magical plane interrupting devices even when they're spread out. Cant wait for man "arrested for using a IR thermometer and having the 1mw laser on" and hit a low flying plane by accident In this case I think a hid spotlight with a green lens on it...

    CNI and their 604/607nm DPSS...

    thanks are they normally prone to mode hoping like that if it's not warmed? it makes my lab 473 that takes a minute to peak like there's no mode hoping and its from 2003. any idea how much current they use and % efficiency? ( the 561)

    CNI and their 604/607nm DPSS...

    what magic drives my 561 3mw cni pen it won't it peak to the front of it gets warm. If it's in a room that is 80 f it comes on much quicker. 68 f takes awhile. What diode and crystal process is in it?
