Dear fellow collector, Dear visitor
To complete the Datamath Calculator Museum we need your help. Up to now
we got no picture or technical data of the calculator you searched for.
Maybe you already own one? We like to ask you if we can place your picture here?
How to Scan a Calculator
|Thanks for your help to complete my
little Datamath Museum. To give a homogeneous look and feel of the pictures I recommend the following
technique of scanning.
Best results were given with an oldfashioned scanner using a lamp and moving optics instead of a LED-array.
|Place the calculator roughly 1 inch
away from the front of the scanner-window.
The calculator should be 1 inch away from the left side of the scanner, please align the calculator carefully.
Position the calculator in a direction that the displays "shows" to your direction.
This position gives due to the optical path of the scanner some kind of 3D-imagination. If the depth-of-field gets large, e.g. some desktop calculator it is better to align the calculator in the middle of the scanner.
|Place a light-blue paper above the
calculator to give a neat background.
The paper shouldn't be too dark.
Scan with a resolution of 150 dots/inch
and leave a border of minimum 0.5 inch around the calculator.
If your scanner software distinguishes between object sources, try "matt photopaper".
For most collectors some technical specifications are from high interest. Please feel free to decide whether you will disassemble your calculator or not.
