    Antimatter

    You don't sound stupid, you're right actually. Yes as black holes eat up matter they get bigger. The Schwarzschild Radius equation describes the the size you would have to compress something in order to make it into a black hole. Also that implies that for a given mass of the black hole it has...

    Antimatter

    I get what you're say, yeah it starts as energy then turns into mass then back into energy, but that is not what I'm referring to. Particle antiparticle pairs appear out of nothing, no energy or mass is present or changing forms. Unless one of the particles had negative mass it would violate...

    Antimatter

    Before and after the fact that argument may be true, but during the instant that they exist, if they both had positive mass, that would break the laws of physics. Stray energy does not just coalesce into a couple of particles and then back into energy. That's not what's happening. They appear...

    Antimatter

    An antiparticle DOES have negative mass. That is why subatomic particle-antiparticle pairs can randomly appear and then annihilate each other. The net energy of the interaction is 0 E=mc^2 So since the antiparticle has negative mass, the net mass is zero and thus both sides of the equation...

    Blue laser under $300

    K, I'll take some pictures for ya. This is the 445nm diode. So both the positive and negative pins are NOT connected to case ground (which is convenient). Also the driver's input negative and output negative are not continuous. So the diode + and - gets soldered to the drivers output. The...

    Blue laser under $300

    I agree with this too. Hell even my 6x build has an acrylic lens. I'm a wavelength guy. I don't really care if my lasers aren't too powerful, and buring stuff gets old real fast. IMO if you're buying a laser just because you want to "burn" stuff, that's pretty childish. Just my opinion of it...

    Blue laser under $300

    The diode gets pressed directly into the aluminum heatsink which screws into the body of host. IMO is is not anymore difficult to build. In many ways it's easier because like I said it's all one solid piece. You don't have to fuss with heatsinks and setscrews and what not. Everything lines up...

    Blue laser under $300

    Don't bother with modifying a flashlight host into a laser. Contact Ehgemus for a custom aluminum host. http://laserpointerforums.com/members/ehgemus/ Take a look at what he can do. http://laserpointerforums.com/members/ehgemus/albums/custom-host/ He'll make you whatever you want and his...

    Oh thats just dirty.....

    You think the Chinese will give a shit how many signatures they get? You can police foreign companies. The best we (the US) can do is quit importing their crap. -Tony

    What Electrical Circuits Look Like to Me

    Hmmm I think I've built that circuit before. If I remember correctly it's a schematic to a machine that makes dehydrated water. No, actually, it's a circuit for a calculator that can divide by zero, thats right... I like that "NOT A RESISTOR Wire just does this" part. Hahaha!!! -Tony

    micro boostdrive vs flexdrive from 18650 driving 445nm LD

    Technically you can use any rectifier that can handle the voltage and current. You'll just need to measure the voltage drop of the diode at that current and then use enough of them in series to emulate the voltage drop of the real diode, ~5v for 405, ~4v for 445nm, ~3v for 650, and ~2v for IR...

    Made Laminar Water Jet

    I wouldn't use a laser though, 3W LEDs would work much better. -Tony

    Made Laminar Water Jet

    I've built one of those. I never though to put a laser on it though. They're pretty cool. -Tony

    Driver Compilation Thread - All Drivers In Just One Thread!

    I've experimented with a joule thief circuit to drive laser diodes. The problem is that they are NOT voltage regulating or current regulating. As the input voltage changes so does the output voltage. It's difficult to calculate load currents and such because it's not smooth DC. It works for LEDs...

    I hate the term "1 watt"

    Technically these diodes fallow more along the characteristics of 2w diodes. If the manufacturer denotes them as 2 watt diodes that the optimal life output is about ~.7 of that, 1.4w. These diodes have been proven to be able to produce over 1.8 watts of optical power. Whether or not the driver...

    Pink/Magenta wavelength?

    The best you can do is to combine violet and red lasers to create magenta. It's a very unique color. -Tony

    Where to buy good yellow/orange lasers or laser diodes?

    I didn't know you can tell a difference between the two. They're only 4nm different. Regardless of power or color I'd want the one that's more stable. They both use some pretty complex DPSS systems. -Tony
