giha woo: constrained ball
'constrained ball'
'constrained ball' is a drawing aid created by korean product designer giha woo.
once attached to the pen, this device helps to draw straight lines without using a ruler.
normally, a ball point pen rolls freely in accordance with the ball located at the tip of
the pen. however, this writing tool prevents winding lines by helping to move
the ball in one direction only. using the installed measuring wheel indicated on the
product, users can draw the exact desired line length in both a horizontal and vertical
direction, as well as strokes in 45 degree angles.
the mounting area is made with a flexible rubber material helping it adhere to the attached pen.
measurement of line is indicated on the product
if it absolutely needs to be straight use a ruler, or it doesn't so just draw freely?
practice practice practice
a video of this in action would add more credibility
you cannot draw a straight line with this device
(+)the design is nice.
consider a situation where u use the rubber as the centre of a circle and you use the pen to draw a circle around that centre. your measurement is all wrong as the rubber never moves.
also it could it not be powered by some super small super savy dynamo inside...
very good idea!!
automatic shovel; fabulous idea.. maybe with a rubber shaft to reduce fatigue.
Nothing is avoiding the devise to go around the pencil; you are relying in a rubber to keep it in place. This is my simple opinion.
What if I want draw line from point A to point B, which are far from each other ... laser line is not here
A ruler don't break, is cheap, not constricting the pen, there's just so so so much that I cba typing. Seriously think about using this for a project not just drawing a line.
Ruler FTW.
want one!
if really... perfect!
Idea has potential.
