Makers, let’s say you could only have 4-5 pages of important charts, formulas and references – what would they be? Here are a few to get you started…

  • Resistor color code chart
  • Capacitor code chart
  • Key to schematic symbols
  • Simple circuits to build
  • Drill size conversions
  • Screw measuring card
  • Formulas to calculate areas and volumes
  • Common fraction to decimal conversions
  • Simple origami (cup, paper airplane)

What are some other handy ones? Diagrams, conversion tables? Post in the comments!
