If you are looking for a stylus that works with your capacitive touch screen, you may want to consider making one at home. This is not only cheaper than buying a stylus at the store, but it can also be made using items that you might already have around the house or in your office.

Capacitive styluses work by transferring electric charges from your hands to the touchscreen. This allows them to work with all types of screens (including resistive, infrared, and optical) that accept touch input from fingers.

The best way to determine if an object will work as a stylus is to check whether or not it has the features you need, such as pressure sensitivity and tilt and rotation detection. These are the two most common criteria for any device and stylus to meet, but there are many other things that you should consider as well.

1. Conductive material: This is important because the signal from your hand to the screen needs to be able to carry enough electricity to activate the touch screen. A non-conductive material will block the charge from reaching the screen.

2. At least 1/4 inch wide: When filtering data, the processor ignores areas that are significantly smaller than a human finger tip, so if your object is too small it may not be detected.

3. A relatively flat end: You want the tip of your stylus to be flat, so that it can touch the entire face of the screen without being too bulky.

4. A smooth surface: Having a smooth tip will help prevent scratches on the screen.

5. A conductive material: An electrical wire, an old pen, or a piece of conductive foam are all examples of conductive materials that you can use for your DIY stylus.

You can also try wrapping a piece of aluminum foil on a pencil or pen as a stylus. This will not only work, but it will look pretty cool as well!

6. A cotton swab or sponge: Cotton swabs are a great choice for this type of stylus because they do not need to be soaked or dripping wet. They just need to be moistened and your fingers should touch them when you are touching the touchscreen.

7. Various metal office supplies: Scissors with metal handles, name tag clips, binder clamps, and unbroken bunches of staples are all great choices for a DIY stylus.

8. Other conductive objects: A piece of tin, a plastic tube, or a piece of aluminium foil are all excellent candidates for this kind of DIY stylus.

9. Other insulating objects: The negative end of a battery (such as a AA, AAA, or AAAA) can also be used as a conductive stylus with minimal modification.

10. Other useful items: You can also try using a piece of wood as a stylus, but you will need to be careful not to scratch the surface of your touchscreen with the wooden piece.
