Step 2: Design of the card (part 1)
The original radio shack card shows color codes for resistors, capacitors, and inductors, but to be totally honest, I have never used the inductor side, and rarely have I ran across color coded capacitors (in some vintage radio equipment maybe), so I choose to not bother replicating those, My card will do resistance only.
Also the radio shack card, in accordance with standard resistor color codes shows gold (/10) and silver (/100) on the 3rd band, again something thats not really likely to come up in hobby electronics, so due to part lazyness and part "how am I going to print metallic colors on a inkjet" those 2 are not included in the multiplier section.
The card can show values from 10 ohms to 99 meg-ohms with no confusion , and that should be just fine for most applications, heck the Radio Shack card only does 99 meg- ohms ...
Now on to the design but!
IF you have no interest in how I actually made the graphics for the card, and just wish to print out an image and assemble it please skip ahead to step 7
