^^ 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

Re: What's You're Favourite Energy Drink? four loko! (just kidding). Just some funny thing I found.. Honest Four Loko Commercial - CollegeHumor video (I like coca cola, I know its not technically a energy drink though..) --Hydro15

You can use DealExtreme: $2.80 High Temperature Tape (10mm / 300-C) to insulate the axiz module from the host. It works great, I used it on my white fusion build. It does have an effect on the heat transfer, but its really negligible. --Hydro15

Very cool stuff.8) I took a small solar panel and shined my .5 watt 445nm laser at it to see what would happen. It outputs A LOT. I bet if you could aim multiple 1 watt 445nm lasers at it you could make it strong enough to power a small rc helicopter (just make sure you don't melt the solar...

Tritium is a gas at standard room temperature, so it must be trapped to keep it from escaping. There is very little tritium on earth, and it has a half-life of 12.3 years. Commercial demand for tritium is 400 grams per year, and it costs $30,000 per gram... And after 12 years half of it will...

Best youtube video of all time. YouTube - How to make a nuclear reactor at home Don't do it, you'll just end up with a bunch of radioactive crap everywhere + radiation sickness. The man built no reactor of any kind, just a big mess. --Hydro15
