  This is the Raspberry PI and Electronics Printed Circuit Board Ruler from Kickstarter. In case you now missed the campaign you can now get your own!
  This is a slightly updated version. I’ve made the graduations easier to read by varying the heights of the lines, and I made them slightly skinnier. Ohm’s law is now V/I*R.
