A proposal for Instructables and fellow Investers

Dear staff, I didn't knew who to actually send this message to so i posted it here. I come here with a proposal which will make your site get attracted to more traffic or as for investors reading this you could make double or even thriple the amount. As you know i have made 1 million dollars in just 1 year and i wanted to show how i did it exactly and how people can eventually make 1 million in 1 year. This guide is no scam and is a real story which i accomplished without going online like most teen millionaires. It's my hard work and it did pay out well. So here is my proposal, i will sell you my " Make 1 milion in 1 year" Instructable or ebook for $ 100,000 + (price negotiable) and i will give you full rights to it. You would be able to double or even thriple your site traffic with this instructable and for other people as such who are interested in buying it can set their own website and make 10 times more by simply getting ad revenues and or selling it. I am giving you this proposal as a only chance, and if i wanted to earn any more money from it i would have already. Made millions from it but i am not interested because i have already acomplished my mission and thats enough for me. So dear ibles staff if you think you would like to buy the instructable then do private message me as soon as possible cause it may be too late. Thank you for your time.

What about a 3D simulation device??

Hi, Instructables community. This is a great place for making and sharing our projects. I am working on a 3D simulation device that uses rotational and linear motion wheels' axis as well as servos to control the finger position. What do you think about it? I had already made up a prototype. Can you suggest me if it would be a useful device? I think gaming. What are your views?? Thanks! :-) See you soon.....

Water purifiation for flood victims

Hi, I am a flood relief volunteer based in India. During flood, many children get seriously sick due to consumption of contaminated water. The flood water is contaminated with suspended particles,rotting organic matter& pathogens( specially E-coli) . These people do not have access to electricity,sanitation & medical relief. I am working on small, cheap & effective water filters that can be made/assembled at the site. If someone can suggest methods to make effective turbid water filters using commonly available materials, or send me the links which can help make these filters, it will be a big big help. Thanks, Chandan Singh,GreenPower India.Images of last yr floods 1Images of last yr floods 2 Images of last yr floods 2

Inventors needed

Dear inventors and instructors, Let me welcome my self , my name is Arylic Singh and i have just started a small company called : Arylic which is divided into three small component companies which include Arylic Robotics, Arylic Green and Arylic Inventions. You see the main goal of our new business plan is to use the least amount of money on the publicity and the advertisements and gain as much profit on the sales. So our objectives now is to look for young and old inventors and makers and make deals with them for their invention or products. So what we do here is we take the idea or plan or prototype of the invention or product and manufacture it under the companies name but their would be a deal that 30% of every sales goes to the inventor. There is a advantage to the inventor because he/she does not need to put any money into the manufacturings. SO now we are looking for new and fresh inventions and inventors to join our company and sit back and eat the creams........ Pm me for further information or post here.
