ComponentLabels

This script generates labels for zip bags with all sorts of electronic or mechanical components.

It is primarily meant for these labels (70x25.4 mm) and these 8x12 cm zip bags. However, the generator script also supports AVERY 5260, AVERY L7157 and AVERY J8157 labels.

Supported components

• Resistors (resistance, 3 & 4 digit SMD code, EIA-96 code and 3 & 4 band color codes)
• Capacitors (capacitance, 3 digit SMD code, EIA-198 code and 3 band color code (yes, those appear to actually exist))
• Diodes & Schottky diodes (name, forward voltage/current, reverse voltage)
• Zener diodes (name, reverse voltage/current, forward voltage)
• LEDs (diameter/name, forward voltage/current, wavelength)
• PNP/NPN BJT (name, base-emittor voltage, collector-emittor voltage/current)
• P/N-channel MOSFET (name, gate-source voltage, drain current, drain-source voltage)
• Square/Hexagonal nuts (thread type, thickness, width and diameter)
• Washers (thread type, thickness, diameter)
• Recessed/Round-head/Flat-head screws (thread type, head width, head height and screw length)
• Threaded inserts for 3D prints (thread type, diameter and length)
• Compression/Extension springs (diameter and length)

Usage

• Install python3
• Install the python3 library reportlab. This library is used to do the actual PDF generation.
• Add your own required resistor values in main() of LabelGenerator.py.
• If using Avery labels, change the layout value in main() to AVERY_L7157, AVERY_5260 or AVERY_J8157.
• Run the script LabelGenerator.py!

It will now generate a ResistorLabels.pdf that can be used to print onto your label of choice.

Label alignment helper script

A helper script is available to assist with creating new label definitions.

If you scan a blank sheet of labels of your choice that you want to create definitions for, this helper script can overlay the scanned blank page (with the seams between the individual labels visible) with your generated labels. This way, you can verify that your new label definitions are correct without the need to print anything.

For example: ./scripts/check_alignment.py --template scanned_labels.pdf --labels ComponentLabels.pdf --output combined.pdf will produce a file named combined.pdf that will have the scanned labels as a background for each page and the generated labels overlayed on top.

Of course, this script assumes that your scanner is properly aligned and set to the same page size as your generated labels.

This is forked from https://github.com/securelyfitz/ResistorLabels, which is in turn a fork of https://github.com/Finomnis/ResistorLabels.

The original is based on an idea from Zach Poff. I liked the design of securelyfitz's forked labels, I just needed to implement more than resistors.
