Alternative to keyboard

On top is a joystick like an NES joystick. It registers 8 different directions: up, down, left, right, and the in-betweens of those and is controlled by the thumb. Then there are 4 buttons, one for each finger. The joystick replaces the trackpad of a laptop and hopefully is also 'clickable'  to act as a 'left click button. I'm not sure what would do the right click button. Combinations of button presses and joystick directions would replace the keys on a keyboard. I only have the use of my right hand. I initially thought of this as a device for handicapped people like myself, but it would also be good for people lying in bed. The concept maybe could be made into a cell phone case with physical buttons that would allow people to text without looking at their phones. The device is a lot like the nintendo wi remote, but not quite. Maybe a wii remote could be hacked to make a prototype. I wouldn't know how to do that and I wouldn't know how to program it, that's why I'm posting, to see if someone could tell me what kind of skills/knowledge would be needed to make this idea happen. Any suggestions or offers to help are welcome. Thank you!

Our main source of  energy right now is nuclear energy. Although Nuclear energy  might seem to be a reliable source of energy, it is not.  Nuclear energy is not a reliable source of energy  because you need to extract Uranium ore from the earth's core which might seem as a good  source of Uranium it is not. This is not a endless supply  of uranium because it will eventually  run out of uranium .   So what can we do to solve this issue? The answer is alternative energy.  Alternative energy  is energy that can be renewed  and that is reliable. One solution is replacing Uranium fuel rods in a reactors core with Tritium. Tritium can be used  as a substitute for uranium because it has the same properties as uranium except that it has a shorter  half life.  Tritium is made by fusing solid  Hydrogen With Lithium  in a Farnsworth reactor.  This also has its problems one major  problem is the radiation and heat that is generated during the process  of fusion. Tritium can be then used as a fuel  pellet for a Nuclear reactor when it is mixed with Deuterium which is a solid. Tritium is also a good fuel pellet because it only has a life span of about 12.4 years, then  it decays into Helium 6 which is very harmless. Uranium on the other hand is not  safe because it has a life span of about 2000 years and it gradually decays into other radioactive material such as Thorium, neptunium, ECT.... This is Called the Uranium - Thorium cycle. The tritium is also ecologically friendly because it  can be made from H1 which is found in water H2O.  H1 is called Portion and is extracted through a process called electrolyses in which water is charged by a D.C current.

Alternatives to kite power

I was looking though my old MAKE magazines, and found the schematics for a Kite Aerial Photography rig. For those unfamiliar with the term, it's a camera attached to a kite that allows for aerial photographs to be taken remotely. However, I live in Texas, and the only time the wind blows here is when it rains. And rain means lightning. So, rather than risk electrocution, I'd like to come up with some alternative methods of lift. I was considering a large helium balloon (like a weather balloon), but I was wanting something that I could say I made myself. Then I considered hot air, but I'm not sure how large a homebrewed hot air balloon would have to be to lift a camera. Any suggestions?

alternative to conductive thread.

Ok guys, so i was finishing up a project with my guitar, and i ended up replacing the strings. so i though to myself... what can these be used for. I decided to use them in a project im working on involving a belt, and regular wire would not work well. So, i weaved the guitar string throughout the belt, like you would with conductive thread, and its very very strong, and also flexible. And since its meant to withstand a beating it should last nearly forever. The strings i found to work best are the 3 smallest ones, E B and G, the others are too rigid to bend as much as needed. in the picture that is the third string, so it is more rigid then the first on would be, and i found it to work excellently for what i needed it to.

High Frequency Alternators

Look at a picture of some arcs from a common spark-gap Tesla Coil, and then compare it to the arcs from a solid-state. What makes the two so different? The difference comes from the Solid-State Tesla Coil to operate in CW (constant wave) mode. This means that its power supply is uninterrupted, whereas in a spark-gap type, power is being switched on and off hundreds of times per second. If the output terminal of a CW coil doesn't have a brake out point, no corona or spark will occur. For anyone who's investigating wireless power transmission or Tesla's version of radio, this is a very helpful feature, since corona only wastes energy. And if it does have a brake out point, it can create some pretty interesting spark displays, as I mentioned above. An arc to a grounded object increases the current in the arc to such a point that it turns into a white-hot "flaming" discharge. All-in-all, a CW type coil is a pretty interesting kind to observe. But solid-states can be pretty difficult and annoying to build, and expensive as well. Since solid-state technology obviously was not available to Tesla, he found a different way to operate his coils in CW mode- a generator that was specially designed to produce radio-frequency power. He had originally created it for high-frequency arc lighting. Today, I have seen absolutely no coils run by a high frequency alternator. Of course, an alternator would be admittedly difficult to build, but since it could probably deliver more power than a solid-state coil, it would be worth it. Does anyone know if there are any companies that still make these alternators? Would anyone be interested in recreating it? Should we even bother? Thank you for listening. Peace!

I've had an idea of one method. Get one of those realistic fake cats that breathes and put the scroller in it's back. Then you can cradle it in your arms Dr. No style and stroke it's back, all the while scrolling down a page of your choice. I also thought of somehow making the whole right side of my desk a massive scrollbar, but it would be a bit complicated for my liking. So what do you think?

No ones gonna be sitting on the desk or anything. I would say NEVER more than 50 pounds on it, but 25 is probably gonna be the maximum, and not even that most of the time. (just gonna have my laptop and stuff on it, maybe some textbooks). And im assuming a blue light LED would shine through it fine..I kind of want the frosted look (would sand it down a little bit to get rid of the "bubbles") to give it an effect similar to the lights in this: except without the notifications and stuff.

The more natural way of cleaning things...

At my workplace we basically have a specific cleaner or cleaning product for every task you can think of. From glass over stainless to plastics and desinfectants for lots of different surfaces. After a quick look into my cleaining cabinet at home I started to wonder if I am doing something wrong as I only have a few cleaning things for my use. Asking my friends also showed they have a big bunch of cleaning chemicals, plus the bottle of bleach that everyone down here has. So I though: Your grandma only had a few cleaning products and you learned most of things you need to clean from her. Considering I grew up healthy I guess she must have done something right.... Let's clean up with the cleaning myths, shall we? 1. What cleaning chemicals do you have? For quite a few people the list would start something like this: Dishwashing liquid, window, cleaner, bathroom cleaner, soap scum remover, floor cleaner, oven cleaner, several desinfectants.... If that is true for you too than we might be on to something already. 2. What cleaning chemicals do I really need? This is a good question as everyone is a bit different but I assume a healthy household here. Of course we need certain things to clean our various surfaces properly but it is far less than waht you have been told by the TV commercials.... These days we like to think if there is a special cleaner for something then of course we have to use it to clean properly. Unless you have trades people walking through with their wet dogs several times a day and see dust storms at least twice a week you really only need a few things. So let's get to the basics: 3. Old style cleaning and what you need for it - really the only stuff required to keep all clean and sanitised. a) Methylated spirit b) Clear ammonia - cloudy ammonia works too but be aware that the added soap can be a problem that leaves streakes c) Hydrogen peroxide - pool grade to be cheap in the long run d) Orange oil - citrus oil works great too if you prefer a different smell e) Soap - just basic soap, these stinky, slightly yellow and hard bricks - no fancy smelly soap ;) f) Several cleaning brushes but you should already have those g) Windows cleaning tools - the basic microfibre cloth and squeegee will do h) Several microfibre cloths - bigger ones for floors and walls, smaller for windows and the rest I) Yesterdays newspaper j) Baking soda With those few things we have everything to clean whatever comes up and if bought in bulk comes down to a few cents per bottle compared to a few dollars when you buy all the stuff you don't need. Lets figure out what the stuff does and how to use it: 4. Mixing and what to use it for.... The alcohol is a really good remover for everything greasy and also desinfects the surfaces. A quick spray and wipe on your bench is all that you need to remove oily residue or the mess from the kids. Mixed with a bit of soap and water (about 50-50) also removes sticky stuff like jam or syrup. If we use about 50ml of alcohol, 50ml of clear ammonia and 900ml of water we get one liter of really good window cleaner. The modern way is to use microfibre for the cleaning and a squeegee to get it dry, the old way just uses a cloth and then the window is "polished" with some old newspaper. The black ink reacts with the alcohol and form a mild abrasive while the paper soaks up the moisture, the result is a prefectly clean window in under 3 minutes. Orange oil is not only a powerful degreaser but also lifts old dirt or even glue residue. Used directly it will get rid of the remains from sticky tape, stickers and everything that other cleaners fails to get off - smoth surface and non soaking of course. 50ml of it with 50ml of ammonia and 100ml of alcohol per bucket makes a good florr cleaner and your house smells nice when done. Works best if you can use a microfibre cloth or floor wiper to dry the surface with it. In the kitchen we can find a lot of surfaces that are greasy and we already covered that bit, so lets get to the though stuff. The kitchen sink can become dull looking although it is not scratched. This is due to hard water, food residue, soap and other things. Best is of course to wipe it and dry it after use but who really does this every day? A pot scrubbing pad with some baking soda on it does the trick here. Make the pad nly moist and sprinkle the baking soda on it. Rub over the stainless and if too dry add a few drops of water. Once done rinse off and enjoy the difference. For hard to clean or badly turtured sinks you can try a ball of aluminium foil and coke - use it like a polish. The oven is often our worst nightmare. The cooktop is not far behind. But even here we can have a chance to clean without too much hard work or bad chemicals. Of course the best way is to prevent these spills and boil overs ;) For the cooktop some hot water and baking soda will soften the baked on stuff. Simply remove what you can with the hot water and then sprinkle the surface with baking soda. Cover all with the paper towels and if not wet enough add a bit more hot water so all shets are soaked. Leave ove night and wipe clean the next day. The oven is a bit of a problem once the side and back wall are filthy. If baking soda with a pot scrubber won't do the trick get some of these steel pads with soap in it. The soap in them is special in terms that you only need a little bit of water to remove almost anything with them - and they won't scrath enamelled surfaces. On the bottom we often have badly burnt in things that are next to impossible to fully remove. I suggest to cover the same way as the cooktop but also to add some orange oil. Just make a thick paste of baking soda and orange oil and wrok it into the soiled surface. Cover with wet paper towels and leave over night. Now you don't want to flood your oven, so that means you need to use a sponge or thick cloth that is big enough to wipe off the surfaces you soaked the day before. As the orange oil really is oil it pays off to use some alcohol in the cleaning water to get rid of the oil and grease a bit easier. Don't expect to see a clean and shiny surface after one treatment if the oven was badly misused, you might have to repeat the procedure a few times. If in doubt use the soapy steel pads for last clean and before soaking over night again. Three to four treatments are usually enough to clean even the worst disaster that can happen in an oven unless you baked it in for months... 5. Desinfecting and mouldy spots.... As said, the methylated spirit is basically just pure alcohol and kill almost anything that might harm you. But sometimes that just is not enough. And who really wants to spend an hour or longer to clean some mouldy spots in the shower or try to cover the smell by spraying room freshener? As a lst resort for everything I use Hydrogen Peroxide. The supermarket grade is only 3% and usually badly overpriced, so I suggest to get a small canister of pool grade peroxide. Do yourself a favour and ask them to install a tap on it - you don't want to do it yourself unless you already know how bad pool grade peroxide is! For your own safety when handling it I strongly recommend wearing long rubber gloves, nitrile is better but please no latex as it could start to burn when getting in contact with the peroxide. For high grade desinfecting or the removal of mouldy areas I recommend to dilute 1:5, one part of peroxide to 5 parts of water. Only for the mould removal on tiled, plastic, glass or metal surfaces you can use the peroxide pure from the container - but please add face protection when cleaning! Some spray bottles work with peroxide some just start leaking badly, if you want try an old bottle of chlorine based cleaner after really flushing everything out. The peroxide breaks down any organic material it comes into contact with, so not just the mould you want to remove but also your skin or eyes if you allow contact. On the skin you see white areas after contact and they won't go away until all the oxygen in the skin is gone that was left by the peroxide. If you act too late it means you might loose some skin flakes. The sure sign of overlook exposure on your skin is a burning sensation in the area - this only happens when the amount was big enough or your clothes got soaked. On your surfaces to clean you will notice bubbles forming quite quickly - this mean the peroxide is reacting with something, usually organic material. Let it bubble... Once it stops bubbling the surface is either sterile or the peroxide is used up, if it bubbles when adding fresh peroxide onto it then there is still crap left ;) It really helps to brush off the surface after each treatment as a lot of loose material will be flushed out when rinsing off. Once it looks and smells clean again it usually means it is clean :) 6. Special case: Wood... Be it wooden floorboards, furniture or just your chopping board - always try what the manufacturer recommends first! Untreated wood should never be cleaned with anything wet! Sealed wood, like floorboards or things with varnish on it to make it water proof can be cleaned the same way as mentioned above - but I would leave out the ammonia as some wood treatments simply won't tolerate it and might go dull instead of returning nice and shiny - spot testing required if you think you have to use ammonia as well! Orange oil itself makes a great furniture cleaner if the surface is smooth and sealed, but if it is not it means the oil soaks into the wood together with the stuff you want to clean off! It also takes off several paints and types of varnish if you work it hard enough and give it some time, so avoid this and be quick instead of forgetting to finnish the job ;) Always try to wet the surface as little as possible and wipe fully dry as soon as possible! Ok, good start but what is the real benefit? For me the actual benefit is that I know what I am using and exposing myself to. Just reading what is in most cleaning products we find at the supermarket makes me want to clean again after using them, just to remove their residues... I admit it might take some time to get used to mixing and just having a few ingredients for the cleaning but it does work great. Especially if you or your kids are already sensitive to certain chemicals or just of poor health in general you might see the benefit quite quickly. Some people really don't like the smell of ammonia but unless you are sensitive to it there is nothing to worry when using the household grade as we always dilute it down massively anyway. A good way to avoid the worst stink is by mixing it outside with the wind from behind. I won't say that certain commercial products are bad, harmful or not good enough for the job. Some are actually worth to have in some cases but I just say it is better to only have a hand full of chemicals that are not too bad instead of an endless list of things were we don't even know what's inside. For me the best is your surprise when it actually works better than you expected and report your findings here.

Are there any alternatives to piezoelectric transducers?

I saw a post about an energy-generating device on shoes which generates electricity when walking. Piezoelectric transducers were used to generate energy but not enough to charge the battery full or even half full. Are there alternatives to Piezoelectric transducers that generates more energy than piezo? Thanks.
