Resistor image generator
I got nerdsniped into making this.
Requires "Pillow".
This script generates a folder with a bunch of images following a given E-series of preferred numbers, along several decades.
See E series of preferred numbers on Wikipedia for more info.
All E-series (E3, E6, E12, E24, E96, and E192) are supported. Tolerances can be set to one of:
- 0.02%
- 0.05%
- 0.1%
- 0.25%
- 0.5%
- 1%
- 2%
- 5%
- 10%
- 20%
Tolerances are limited to the maximum tolerance for a given E-series.
Images will be placed in a directory named after the series in the current directory. Files are named with <resistor value>_<tolerance>pct.png. The resistor value is written in the convential way with suffixes: if the value is less than 1,000 ohms, R; if it's more than 1,000 ohms but less than 1,000,000: k; if it's more than 1,000,000: M
The script doesn't accept any arguments; to generate a different series or at a different tolerance, edit the last line of main.py.
You can also edit several of the variables to change the dimensions of the generated images. The maths are done in a way so it should be pretty adaptable.
Apologies for the somewhat messy code (particularly all the global variables). This was just a little fun project and I have no intent to build anything further from it.
