is wiikey fusion legal? Answered

Is the wiikey fusion legal in the us? i'm going to make a portable gamecube, and i'm going to use that if it is legal. i realize that, even if it was legal, using it with games you don't legally own makes it illegal. I will only be using my games i physically own, legally bought. any info is appreciated.

A hotbed of cold fusion

I'm a sucker for fringe science. What can I say?From the BBC News Service:The long-standing debate about cold fusion is receiving new impetus at the American Chemical Society's national meeting in the US this week.Cold fusion, first announced 20 years ago on Monday, was claimed to be a boundless source of clean energy by Martin Fleischmann and Stanley Pons.Attempts to replicate their experiments failed, but a number of researchers insist that cold fusion is possible.The meeting will see several approaches that claim to produce fusion power.See the full BBC article here

Cold fusion experiment

I have reproduced some experiments on Cold Fusion. not as a source of energy but how to blend a wire of iron from 2mm with less than 2 ampere or obtain gas fuel from the water and graphite (coh4) without using dozens of amps.Do you think may be is interesting to do an instructabels to the matter? are not my nventions!I have same video of this experiment on my youtube channe http://www.youtube.com/user/alessiof76 Almost all in Italian language.. but with a little explanation also in EnglishThe power supply that i use and the experiments can be dangerous..

Scientists plan to ignite tiny man-made star

From www.telegraph.co.uk:"While it has seemed an impossible goal for nearly 100 years, scientists now believe that they are on brink of cracking one of the biggest problems in physics by harnessing the power of nuclear fusion, the reaction that burns at the heart of the sun.In the spring, a team will begin attempts to ignite a tiny man-made star inside a laboratory and trigger a thermonuclear reaction.Its goal is to generate temperatures of more than 100 million degrees Celsius and pressures billions of times higher than those found anywhere else on earth, from a speck of fuel little bigger than a pinhead. If successful, the experiment will mark the first step towards building a practical nuclear fusion power station and a source of almost limitless energy. Full article.This is big medicine, because while we have (more or less) successfully harnessed the power in nuclear fission, we've yet to find a method of using nuclear fusion for power (outside of experimental/weaponry uses). It is important to note, however, that this initial experiment, while big, won't be powering your home or office just yet-even if it does work, there's still quite a lot that would have to be done to build a nuclear fusion power plant.Still, it's heady stuff, the energy source of dreams-a world powered by nuclear fusion fueled by hydrogen, one of the most abundant elements in the universe-only now that dream is looking like it could, possibly, maybe, eventually, become reality.And now, a word from our sponser resident particle physicist:The NIF at Livermore uses small (BB-sized) pellets of liquid hydrogen (technically a deuterium-tritium mixture) encased in a shell. The pellet is illuminated by a terawatt laser split into 192 sub-beams all focused on a poiint. The outer shell of the pellet is vaporized and a shockwave compresses the hydrogen to the point where it should start fusion.The whole process is over in roughly a microsecond. If you keep dropping pellets into the chamber, then you get a series of pulses, but as soon as you stop, everything shuts down.The NIF (like the NOVA laser before it) is being run at a weapons lab, because the kind of fusion it can do (individual microsecond pulses) is most useful for studying the physics underlying thermonuclear weapons. It is probably not a viable technology for continuous power-generation fusion, but it is necessary for understanding how to make that sort of system work.

Nuclear Reactors and Batteries

Hydrogen fusion is a promising source of energy. They have made fusion reactors already. Though they aren't going to supply our energy needs because they consume more energy than the make. Fission reactors have been already made and are good at making energy. Unfortunately they have dangerous radioactive byproducts and wastes. Please post anything you want as long as it has something to do with nuclear reactors.

How do Tokamaks work?

Ive been reading into the nuclear physics behind devices like tokamaks which are promising candidates for a viable fusion reactor. The thing is, from everything I've seen and read it looks like the popular model for a tokamak is only the in between stage. Its like describing the forces on an airplane in flight but neglecting to explain how it takes off or lands. Can anybody tell me how they get those things fired up and cooled down? And I dont mean the ignition process or simply turning off the input power. I mean how to get the gas inside the darn thing to stay in the containment field until its been ionized? or is it ionized already? Anything at all would be much appreciated. =]

Bonding hydrogen and oxygen to make water? Answered

Ok, so I got how to get water, but how do I condense it without losing much, and would it be at least a semi-efficient and/or fast way of obtaining around a cup of water? So, I have another question. I know, I've been posting a new question at least once a week for a while now and you're all probably like "Dark Master87, Y u no shut up and stop trying to do impossible things?? w(O;O)w" Most people on here probably know about electrolysis and seperating water into hydrogen and oxygen with electricity, but it's simple and I don't currently have a use for it. But does anyone know how to bond hydrogen and oxygen to create water? I'm expecting there to be heating or cooling involved, probably more likely heating. Would you light the two gases on fire? Or would they just automatically bond with each other at the point of contact? More importantly, would this be possible to acheive on the limited budget of a 14 year old hobbyist who *may* have access to *some* lab equipment, but probably not? Thanks for paying attention, if it's not feasible/possible, I won't mind if you nag about me never doing any reasonable projects. And also, how hard would it be to get the hydrogen and oxygen from electrolysis with losing too much of it?

question about TIG fusion welding without filler? Answered

Hello, Does fusion welding of mild steel  with either acetylene or TIG result in the same metal structure; is all melting the same ? Here is a rambling explanation of why I am asking. I wanted to start acetylene welding again but have found that the gas prices here in the UK are even worse than I Imagined. So, I thought to buy a TIG welder : I will be mostly welding 1.5mm mild steel sheet. I used to enjoy fusion welding with acetylene and hardly ever used filler; does fusion with a TIG welder result in the same molecular/chemical structure as acetylene ? The reason I ask is that, I looked at hundreds of online opinions about TIG fusion welding of mild steel and generally they all said not to do it as it will cause the surrounding metal to be brittle; but they were proper welders doing proper structural things; I am only doing scultpures and all of of my stuff from 20 years ago is still holding . . .  so if TIG melting is the same then I will go for it, Thanks

Using Autodesk Fusion 360 or other package to make Lids and other form fitting parts?

First off, thanks for all the great posts and Instructables, I hope to be able to add to the growing collection sometime soon with a few projects I need to document.   Recently I have been trying to figure out a good way to create form fitting shapes with decent tolerances for  PLA printing.  I am using Autodesk Fusion and Blender using Boolean CGI operations, specifically the  Cut / Difference option. to create a appropriate sized cap.  If you have a peek at the attached image, the top part (red)  was used as a tool to cut out a matching body from a smaller cylinder (blue).  In the real world If these are printed, the shape would never fit together and if you did, you could never remove them.   What I would like to do is alter the bottom half to shrink it's surfaces inward about 0.25mm to allow for the expanding of materials. Every time I've inquired about this on some other forums, the first response Is  'Just use resize' and make the bottom half larger.'  Great idea, but there are a problems.  The inner plate/cylinder and radius walls expand to be too large The height changes, leaving a gap between the two surfaces Any suggestions would be great. I believe there is a path using Differences / Intersect and subtracting that, but I've been failing to find a solution to it.  I have included the Example top as an STL file.  Thanks for any suggestions.  And No this is not for a school project. Just a hobbyist looking to understand CAD.

How to back paint clear plexiglass so I can reverse laser engrave?

I'm trying to back paint a piece of clear plexiglass so that I can reverse laser engrave. I'm then going to backlight the piece with an LED panel but I want the paint to be opaque so that the light only comes through the engraved pieces if held up to the back painted side. It will then have a nice look because the clear acrylic will give the lasered piece floating characteristics. I'm able to create this effect using black krylon fusion spray paint, but it just seems to take 3-4 coats in order to block the light out through the paint. I've tried black vinyl, block out sign vinyl and a variety of painted applications but nothing seems to work better than paint. The vinyl applications are also troublesome because the margin for error is too high with vinyl applications as I need the piece to be very consistent on the black reverse side.  I've also found products out there specially made for reverse engraving, but they are extremely expensive, and upwards of 150$ for 24" - 48". I've talked to a couple people that recommended Krylon Fusion normal paint, I'm just worried that if I were to use a roller,  or brush, I'd see the brush strokes from the clear side and it would ruin the piece versus using spray paint, which is slightly difficult to get a consistent piece.  Does anyone have any recommendations for what kind of coating or solution I would be able to use?

Can this work for DIY 3d metal printing at home?

Using metallurgical powders with a precision depositing feeder, layout a layer at a time (obviously) of the part you want to develop within a certain size parameter.  Lower the layer into an induction heater coil to raise the temperature of the powder to just below the melting point then hit it with a low power laser to melt the powder together to make the part, again layer by layer.  Theoretically removing the need for high power lasers and either a vacuum chamber running constantly or a constant stream of shielding gas.  Edit: You apply a vacuum or shielding gas only during the fusion cycle, hence the induction furnace. Removes the need for expensive vacuum chambers or heavy use of shielding.
