Cell phone speaker?

So, y'know how sometimes you might feel like sharing your music with friends, but you dont want to share you headphones? The solution would be to carry speakers, but usually they're sort of bulky and they wont fit in your pockets very well. So, what about cell phones? even some that are maybe a few years old are still smaller then some speakers. Everyone knows taht cell phones can be Really loud, so what if we somehow add a cable to attach to an audio device, and switch around some things inside, and use the dead phone as speakers?! I would try and do this, but i have no idea how, so this is just an idea for you peoples to think about.!

Cell phone radiation boosts brain cell activity in brand new study

Brain cells are impacted by cell phone radiation in accordance with a recent study. The study detected an increase in the metabolism of brain cells. Brain cells were affected in the part of the brain near the antenna of the mobile phone. Brain cells are definitely impacted by cell phone use, according to the research, however further research is needed to discover out if that's a bad thing. Source of article - Cell phone radiation increases brain cell activity in new study by MoneyBlogNewz. Cellular phone brain cell research first done The first research undertaken to examining how electromagnetic radiation from cell phones impacts brain cells was published in the Journal of the American Medical Association on Tues. The research focused on how cellular phone use affects normal brain cell function, known as glucose metabolism. The rate of glucose metabolism in brain cells was increased more than researchers were hoping with cell phone exposure. When it comes to brain activity, the way it's done is with cells creating energy. This is done with glucose. The way brain cells work is that it is produced as necessary. The glucose is produce whenever it is needed by the brain. It's unknown if it's bad or not, however it was found in the study that glucose metabolism amounts are increased artificially with a mobile phone. Further research needs to be done though. How mobile phones affect the brain With all the phone calls going on, cell phone radiation has concerned medical experts. They have worried about what it's doing. The outcomes of previous tests have been inconclusive. A connection with brain cancer was found in famous cellular phone radiation studies. The proof that brain cancer was actually brought on by mobile phones in cell phone users was not there though. There are other things scientists have tried to ling cell phone radiation to. Such things as cancer or dementia due to brain cell mutation are examples. The effect of cell phones on children's brains has been a particular concern because children have thinner skulls, the radiation penetrates deeper and their brain cells metabolize glucose faster. Try to choose speakerphone In a statement responding to the cellular phone brain cell research, the Wireless Association said scientific evidence proves that cell phones, used within limits established by the Federal Communications Commission, don't pose a public health risk. The way cellular phone radiation affects the brain is nevertheless unknown really. Until more research is done, experts suggest Bluetooth earpieces and speakerphone should be used as often as possible.

12-year-old designs advanced 3D solar cell

From Slashdot:12-year-old William Yuan's invention of a highly-efficient, three-dimensional nanotube solar cell for visible and ultraviolet light has won him an award and a $25,000 scholarship from the Davidson Institute for Talent Development. "Current solar cells are flat and can only absorb visible light" Yuan said. 'I came up with an innovative solar cell that absorbs both visible and UV light.

DIY Car Speaker Phone with CB Mic

A project I've been trying to do for the longest time is to build a home made speaker phone for my car. There used to be a car phone in it from the pre-cell phone ages and its always sparked my imagination. Basically, from my cell phone's 2.5mm jack to a speaker and to a mic. Now, I have a CB Radio in my Cruiser and it has a built in PA. So what ever I say will come out a 3.5mm jack, very convient for the input for this project. However, I'm a dummy when it comes to speakers. I would have to build a small little loud speaker that would project the sound from my phone. I took apart a headset, so I have the plug for the headset. Now what I don't know is how the wires are arranged in the headset wire and what's the best way to built that speaker from a 2.5mm jack output. The input isn't much of a problem, just gotta figure out which wire in the headset wire is the input... probably red. I'm not much of a electrical guy and I don't currently own a soldering iron. I just have 180w welder.

Quick-vite idea

*UPDATE 2-15-11* If you are good with cell phone apps and website building and you would like to use my idea please message me. If you do make this all I ask for is a very small cut of the profit, but I really doubt anyone would want to make this anyway. Well, if you do just send me a private message and we can talk about it. Keep in mind you still may NOT TAKE MY IDEA UNLES I LET YOU! IT IS STILL COPYRIGHTED BY ME! Hey everyone, I just wanted to share my idea for a possible website I will be making in the future. I got the idea recently when my mom wanted to invite people over to the superbowl and sent out the emails that day. Many people didnt respont because, lets face it, many people dont check their email more than once a day. My idea would be a website based service that you could sign up for for free or become a member for a monthly fee. How it would work is you could type up your message and then send it to a pre-saved group of all the recipients phone numbers, and from there numbers could be added or removed. The site would then send a text to all of the recipients with instructions on how to respond. It would be something like "I'm having a b-day party at my house. 3:00-6:00 at 52 blah blah road. 'reply the number of people followed by y for yes, n for no, or m for maybe. ex. 3y 2n' " Then the results would be replied back to the website where it would compile a list of who and how many could and could not go to the event. Since sending the texts would cost some money it would have to be made up by advertising space as well as limiting the amount of invites allowed to be sent by the free users. Members benefits could include increased invites per month, more recipient groups allowed to be made, and a feature where you could text your website number from your cell phone and it would update you with how many people could and could not go. Since I'm only 16, I would not know how to create this site or be able to spread the word very well, so I would just like feedback on the idea for now. Please tell me what you think about the idea, and if you think its stupid be honest and tell me. Thanks :) And if you take my idea and start making money off of it, I will press charges. I emailed this to myself to sort of "copyright" it and this forum topic will not be edited ever so this will prove it's my idea as well. So please don't steal my idea.

Making a set of iPod speakers from computer speakers.

I have a set of stereo computer speakers that run off a 9v power supply, I'd like to replace this power supply with a bank of 8 1.2v cells (9.6v) that I could recharge with the original (9v 94mA) power supply. First of all, would I need to regulate the voltage down to 9v, or will 9.6v be fine on a simple amplifier circuit? Secondly, would I need any circuitry to allow the 9v supply to charge 9.6v worth of cells? Would some kind of auto cutoff circuitry be necessary to prevent overcharging of the cells, or would common sense by not leaving it charging for long periods suffice?

Blanket weed killer

My pond gets blanket weed each year. One of the causes is excess nitrogen, but since some of this is due to run-off from farmland, I can only control it to a small extent. I have seen electronic devices sold which are a control box, with some wires which wrap around and around the pipe from the pump/filter - obviously some kind of magnetic or pulsed field is created and this wrecks the blanket weed cells without harming other plants or animals in the water - has anyone any idea how to make one? As you can see from pic2 we get tadpoles, small fish and things - the blanketweed can get so thick that the little fish get trapped in it! I have to pull it out, but often you end up pulling fish etc with it, so I'd like to resolve it. We use barley straw to prevent green algae, but it does not prevent blanketweed.
