Stylus Pen Precision (Dagi)




Hi all

(long time reader first time poster)

I just recived my Samsung Galaxy S 2 last night and wanted to make a stylus for drawing etc.

Most of the guides here are "big" and didn't have the precision i was looking for.

So i dicited to make my own :-)

What you need is 2 normal pens one with a spring that will used for parts.

The only thing you need to beware of is that the end of the spring don't touch the screen directly so it makes scratches - so bend the spring-end on top of the others.

You need to touch the spring when you use it.

I will maybe update the post when i have time but this is it for now - hope you like it. :)

    Wow,that's great,being a scientist I like your your effort in making a precision stylus.

    But if u are looking for a good reliable accurate precision stylus for Sketching(not for handwriting),pl. have a look at Estylo stylus,it's very precise and accurate.

    The problem with styluses like OStylus,Dagi,etc with discs or disc like structures,presently in the market is that the discs of those styluses while touching the screen gives unnecesary lines or points on the screen near the aim or centre point,most of the time.

    I have posted a set on

    regarding accuracy of Estylo.
     Please,see all my 5 image photos and video on Estylo's accuracy feature and my comments on my posts on the above stated flickr website.There,See the image tittled-"Error in styluses with Disc tips (2nd image)"
    (Ostylus tip touching the screen is shown).You will find unnecessary point or line mark on the screen.This is because Capacitive screens can detect blunt edges of disc tips while they are touching the screen.However,Estylo does not have this problem,it's very accurate and simple in design.
