Increase V.Leap

I was think of injecting plastic sponge filled with water as the sole of a basketball shoe, hoping the water pressure could help to increase the leg power and increase the vertical leap. Meaning : using plastic sponge Or rather i think of another alternative,which is to use static electricity to store inside the shoe,which later will transfer from the shoe to the leg of human, and hopefully increase the vertical leap.

increasing wavelength?

Is it plausible to increase the wavelength of, say, infrared light? I have a 808 nm 1 watt laser and i am struggling with researching if it is plausible to do so, and if it is then how it would be accomplished?

Increasing Testosterone

As we age changes happen in our bodies. One of these changes is a decrease in the production of some hormones, one of which is important to men, namely: testosterone. It affects muscle mass, physical and mental energy, and sexual function. Selenium is found in Brazil nuts, and it is important in the production of testosterone. If you are showing any signs of low testosterone, try eating three or four raw Brazil nuts each day. Some suggest a person should not eat too many Brazil nuts. (Of course, I am not mentioning this because I had the problem. I am speaking for a friend. Uh huh. Yeah, that is it. Wink, wink.) Anyway, my "friend" began to notice improvements within a week. You can get Brazil nuts in bulk at many grocery stores, and they may be a simple and inexpensive aid to low testosterone problems. Other things that help low testosterone problems are reducing body weight by ten percent and regular exercise.

Increasing DC voltage

I need to increase the voltage of a battery from ~30v to ~230v, the only way i can think of doing this is somehow pulsing the DC rapidly to create a sort of "pseudo AC" then using a standard transformer to increase the voltage, followed by the standard rectification process. My problem is how to pulse the DC (bearing in mind the pulse will probably need to be in the order of kHz, and the device being powered at 230v has a power rating of 400W) and how to after the rectification process implement a pwm system. In addition, the method of increasing the voltage strikes me as extremely inefficient, so if anyone has any other ideas I would be very great full. Thank you for any help you can provide.

Increase Blog Loyalty? Answered

I just created a free online magazine called Meta Haven Magazine http://metahavenmagazine.com and my intention is to create a community of viewers/readers in which everyone is actively contributing additional magazine content, items, reviews, etc. that is undoubtedly being missed by myself but most importantly being missed by the audience. In return as an incentive if the submitted material is voted upon by the community as being good enough to add to the magazine then in return that person will get the chance to have a free post to promote themselves, their blog or whatever of their choosing. I've noticed since I've launched the contest bounce rates have gone up. Would you change the value of the contest or the contest itself? Thanks – Meta Haven Magazine.

Increase running speed

I don't run very much. I never was all that good at it. Lately, though, I have found the need to improve that ability, specifically my endurance at speed. I can slowly jog a mile, sure, but haulin'-ass-away-from-an-amgry-man-with-a-knife-speeds don't last much longer than thirty yards, if that. I'd like to improve my overall speed if possible, and especially increase the distance that I can cover flat-out before I keel over. I'm not going to be running a marathon anytime soon, but I'd like to be able to get farther than average, as fast as possible, on demand. Any tips for training or proper form? I live at roughly 5400 feet, but I'm just a short drive away from 14,000-foot peaks. I would also like to improve my off-the-line times--in other words, acceleration. If I were to need to run between ten and twenty-five yards, I can do that at my top speed as is, but that speed is not as fast as it could be. I'm generally not even up to full speed until eight or ten yards past the line. Suggestions?

Increase the speed of an electric motor? Answered

My electric bike, seen here, was built for my senior project. I was limited on motor choice, and had to go with the best I had, an old powerchair motor. After 2 successfull attempts at building an electric bike, I have discovered that it is impossible to go faster that 25 mph with with one of these motors. As you can see on my instructable the bike has 6 speeds, with a top speed of 20mph in first gear. however, when I shift gears, the motor rpm's decrease instead of the speed increasing. I have heard before that it is possible to run an electric motor at higher voltages than it is rated, so I was wondering, if i could add a seperate switch and a "booster battery" of sorts, that as long as I monitered the voltage so as to not let exceed 24 volts, if this would be feasible. My only other option would be to add a second motor in parallel with the first, and on the same drive belt. The first option would be the easiest, if it could work without damaging the motor. Any help would be appreciated. Thanks, iloveairsoftstuff

Increasing current for hho cell?

What is the simplest method for someone like me who has very little experience in electronics and a low budget, to achieve a high current output for a hho cell? This is for a hho cell and torch so the voltage must be low and the current must be high. Basically what Im looking for is a cheap and easy way to create 3v -5v together with 10-100 amps. Are there any specific household appliances that can put out this current? Not car batteries, car battery chargers or wall sockets. Also is this enough to kill you or just give you a bad shock?

How to get the best range out of an IR LED? Answered

Hello, I'm using my Arduino as a universal remote and I've got everything working, but my IR LED isn't really strong.  I've read around the internet and all I've found are people using an IR LED with either a 33 Ohm or 100 Ohm resistor in front of it. Currently I'm using this RadioShack High-Output Infrared LED http://www.radioshack.com/product/index.jsp?productId=2062565 [Radiant Power Output = 16mW min  Forward Voltage = 1.2V  Forward Current = 100mA  Wavelength = 940nm] with a 100 Ohm resistor in front of it and only get a foot or two of range.  I'd really like to get out to about 20 feet but I could make due at 15/16 feet.  So I got nose-y and opened up my TV remote... it's all surface mount, but as best I can figure it the signal leaves an IC, goes through a 100 Ohm resistor and then goes into a transistor (labeled 2T) before heading out to the IR LED.  The third pin from the transistor snakes around to a bunch of other parts and I lost.  So I was wondering what to do to increase the range of my IR LED... change the resistor?  Power it via a transistor?  If I can use a transistor does anybody know how to wire it up? Any help is much appreciated. Nick

How to increase NE555 output amplitude?

Hi, I have the following circuit: http://s17.postimg.org/86bus6rm7/Sawtoot_Gen.png which is able to generate a nice sawtooth waveform. When I provide 13.12 volt as power supply, the max peak of the sawtooth will be near to 8.7 volt. There is a viable way to increase this value at least to the same value of the power supply (13.12 volt)? And can someone provide me a schematic based on my circuit? I suspect that this would be viable using a transistor or an op amp on the output, am I right? If i had to implement  an op amp, I prefer to use a "single power supply" op amp, and a common IC (eg an LM358?) Kind regards.

Solar incineration of biomass for increased energy?

Hi. I'm prototyping a solar energy system which basically collects, concentrates, and transports raw solar energy, and I'm thinking of various applications for it. My main interest is in water purification, but electricity is an obvious one as well, which means steam or, preferably, stirling engine generation. So say I had six square meters of sunlight concetrated into a light pipe and filling an insulated chamber. WIth losses that's going to be at least 5 kiloWatts of power, which is quite a bit and would run an engine pretty well. But what if you had some kind of combustable material in the chamber, like waste organic matter? It would burn, obviously, and release extra energy. And with the chamber full of extra heat largely in the form of light, I'm thinking you'd get a very efficient combustion of the matter and some ammount of the smoke. So, does anyone know if this would be worthwhile? Would the extra energy gained make it worth it? What would the emissions be, compared with just setting fire to it all? What happens to carbon at these kinds of temperatures? etc. Cheers!

increase analog read resolution arduino?

Is there a simple, hardware based way to use two analogRead pins on an arduino together for higher resolution?  I have a project that only needs two analog values, but the more accurate the value the better.  I do NOT want an external ADC, I am aware they exist, but I don't have time to get it shipped.  It doesn't need to be fast, or multiply the pins (just a value of 0-2047 would be fine, but 12 or 20 bit equivalent would be better).  Preferably something with just resistors and diodes, if that exists, but more components is okay too.  I was thinking something like a resistor-divider or something, but I can't figure out a simple way for that to work.   Again, I do NOT want a new ADC, I know how they works and that I can buy one, but I prefer just using the built-in one because there's no interface issue.  No matter how simple it "really is" I ALWAYS have a problem getting two components to communicate.    I'm using an UNO
