Use a tool that makes units and scales easier with the Smart Scale Digital Ruler. Ideal for builders, architects and designers, the Smart Scale comes with several useful features. It enables you to take a drawing that is not according to scale and measure it as though is. By using the sliding pointer, you can determine the distance between the start and end of a dimension. Once you input the distance it represents and your required units, the screen will refresh to the new custom scale. Additionally, the Convert function makes it easy to change the display between imperial and metric. Just tap the convert button for the long screen to regenerate to the other version. The Divide function is handy for dividing a space into equal sections. Simply move the sliding pointer across the distance that needs dividing and input the number of sections on the number pad.

Of course, this does not need to be over even after May 2nd; many successful Kickstarter projects go on to a supplemental "in demand" financing phase on Indigogo.
2/ Can we speak about a certain Dpi?
3/ Will it be an E Ink screen? best

Hope there will be a good offer in next week finish line. Count me in
Kicktraq (http://www.kicktraq.com/projects/245093613/smart-scale-ruler/#chart-exp-projection) is now projecting that the project will barely reach the goal, IF the high estimate goes (and not if the low estimate happens). There is a need to do something to increase visibility and get more backers...
I could consider going for two Smart Rulers, but a dual pack is more expensive (2.5% discount) than two individual "early bird" (5% discunt), and Kickstater does not allow multiple pledge.
- a smaller version?
- replaceable battery
- an e-ink display
- all aluminium, that’s great! Keep like that! You are awesome to bring us such an amazing product!
So, if I could slide the index pointer, it showing like a contrasting, over-sized marker or cross hair or what not, then I have fixed the position in a manner that remains until I have a chance to look at it. And if, besides it, is a little label that reads "5.231" (or whatever) right there, then I do not even have to count the finer divisions to know what I measured.
This would permit to move the ruler off whatever is being measured with the dimension still showing.
There are a few more prototypes to make and test to determine what the best positioning of the screen would be for performance. The case will be a dense white cardboard (like the type that iphones come in) so that you can take it with you to meetings or sites and have it protected.
For longevity, we would prefer using AAA batteries, but they're heavier and larger, so we're not positive that they'll fit in after we finalize all of the internal components. It'll be a balancing act of how the ruler functions and weighs vs. it's lifespan.

So do not 'avoid using' the battery with the thought that the battery pack will last five years. It won't." Lithium-ion Battery Life and Death | HowStuffWorks

Laser printers that produce output in a single pass, even those ledger size, are likely accurately proportional. What may be an issue are the documents from the larger plotters, those that are using rolls, particularly pen plotter where the paper is rolled back and forth, and the media likely to slip.
(and by the way, once it was realized that the X and Y were not scaled properly, I fixed it in software since was the writer/custodian of the plotting package. But careful measurement was required to get the calibration value...)
To answer the display question, yes, the scale and units would be displayed on the screen to the nearest 2 decimal points.
Or perhaps have a mode where the slider pointer can stretch or shrink the posted scale.
Does the display indicate the current scale? I mean, if the dimension on the ruler spans a distance of 5 m (the size on the drawing) and the ruler is calibrated to show 5 m in 30 cm, then the scale is 6/100. Is that value displayed anywhere?
