Download the full size image (click to expand it -should get 937x1465 pixels), save it, and print it A4 on a Laser Printer
using 'best fit to page', should get you pretty close.
Not sure about american paper sizes
You need to fix the image to a 40mm disc to work inside an Astro, I probably have some 40 mm metal discs with a 13mm (1/2 inch) hole if you need.
I also have various nylon parts (spacers +discs) which can be combined to make hubs to for external rotary encoders.Note
1) You need to use a laser printer, inkjet printouts will not work with these IR sensors
, the black portions are too reflective.
2) The black segments are deliberately a few degrees wider than the white ones. This is to compensate for the slightly uneven characteristic of these sensors in this application.Here is a set of images for the linear encoder, for 14 magnet outrunners
For the 80mm Turnigy outrunners, resize the image using your printer options -try the printer settings below:
(Landscape, custom size: 26.50 wide, 18.90 high)
For different size outrunners, you will have to work out how to resize it yourself
Single linear images:
For 80mm motors, print Landscape 3.7cm high x 25.71cm wide
For 63mm motors, print Landscape 3.7cm high x 20.28cm wide
here is a link to a linear28 image for 28 magnet outrunners (thanks Tsjoechov)viewtopic.php?f=2&t=28966&start=75
