I have an iPad. I mainly use my iPad to develop apps for business purposes. One of my apps required the use of stylus for writing text. Though the iPad allowed me to by touch, it was still not the same. I think it basically boiled down to the fact that writing with a pen was still more accurate and intuitive than with writing with a finger.
I first searched the internet for compatible stylus and found the only product available was the Pogo Sketch. Unfortunately, that product is not available from where I live. So I continued searching. I found another article in the internet where they have mentioned that you can use anti-static wrapping. The one that normally comes as packaging when you buy a memory or hard disk. I tried that and it worked but it felt like it was a little bit scratchy. Then I read the article in Wikipedia how capacitive touch screen works. So I started experimenting on several materials. I discovered that the negative end of a normal AA or AAA battery works as well.
Reading again Wikipedia, it mentioned something about “anti-static conductive foam”. This is when I made that discovery which I’m sharing right now. How you can make your own iPhone/iPad stylus at home.
What you need is a small piece of “cellulose sponge”. I was fortunate to buy a “Big O” pack of 30 sponges for $4.00 at a Walgreens during one of my trips to the US. I used it for cleaning the dishes of course. It just so happened that I grabbed one of the sponges and tried it on the iPad and it worked. I was amazed at how accurate and responsive it was.
I took an old pen and emptied it out and stuffed it with a little piece of the sponge. I put a paper tape to hold it in place. It also tried it on an iPhone 3Gs and the touchpad of the new MacBook. It really works and it doesn’t scratch the iPad! Best of all, you can do it from home and it’s cheap.
