^^ This Go to your optometrist as soon as you possibly can. 50mW can very easily give you eye damage. --Hydro15

If you still see an after image for more than a few minutes than it could be permanent. Those words were taken directly from my eye doctor. As others in this thread have stated, he may already have eye damage. Make him get them checked out right away, there are things you can do right now that...

You should put this in the win thread. -Hydro15

Re: Simple Electric Motor Demonstration Video Yeah, homopolar motors are pretty cool. They are probably the simplest motors that you can make. The high currents and sliding contacts tend to keep them from being as efficient as other motors, but their low internal resistance allows them to...

If all else fails you can try online metals Online Metal Store | Small Quantity Metal Orders | Metal Cutting, Sales & Shipping | Buy Steel, Aluminum, Copper, Brass, Stainless | Metal Product Guides at OnlineMetals.com They sell all kinds of metals in many different shapes, they will even cut...

You guys know kipkay just trolled all of you right? --Hydro15

I don't think the people who made dead space would be too happy about this. I'm assuming you got their permission to show this video.. Right? --Hydro15

It feels kind of weird to see people celebrating somebody else's death. I mean I know he was a bad guy and there is no justifying what he did. I think I can understand people in New York celebrating, I can't imagine how horrible it must have been for them. The whole thing just made me feel...

From what I've read the diode that it has is 2 watts, and even if you did switch out the 2 watt for a 4 watt I don't think it would increase the power by an amount that would be significant enough to be worth it. In fact, It might not increase at all, because the crystals in it are only able to...

Make sure you get some eye protection cause 1 watt of 445nm will totally destroy your eyes if you use it at close range. ARG - Blu Ray, Argon, Blue, KTP [NR-ARG-EN207] - $80.50 They are not cheap, but your eyes are priceless. IMO --Hydro

Diamagnetism is pretty cool, but as HIMNL9 said the effect is very weak. Still it's possible to see the effect. YouTube - "Anti" Magnetic water and Levitating Graphite by Diamagnetism --Hydro15

I think there is another thing you can do to find out if it's a red or IR diode. If you have a multimeter you could measure the polarity by hooking it up like this: * (+) .......* (-) * If it doesn't read zero ohm's then it's probably not an red diode. There is a thread here showing the...

^^ Exactly. It's a case of better to be safe, then sorry. Never leave your batteries unattended while your charging, and if something does go wrong, just don't go throwing a bunch of water on it. Heres a video I found about showing what happens if you try to put out a metal fire using water...

That was hilarious.:crackup: --hydro15
