PartsPy

What is PartsPy?

PartsPy is a helpful tool written in Python for electronics hobbyist, DIYers, hackers, tinkerers, [insert your favorite term here].
It can accomplish various tasks:

• Determine the value of color-bands resistors
• Determine the value of SMD resistors
• Determine the value of ceramic capacitors
• Search for a part online with its description and datasheet (Thanks to alldatasheets.com!)
• Allows simple conversion between different metric prefixes

How do I use it?

Syntax: $ ./parts.py command args...

PartsPy supports the following commands:

• help : Displays the manual
• res : Resistors
• rsmd : SMD Resistors
• cap : Capacitors
• conv : Conversion
• part : Part Search

Color bands resistors

Syntax: ./parts.py res col1 col2 col3 [col4 [col5]]
Gives ohm value of 3 to 5 bands resistors.

Example: ./parts.py res bk bn bk bn"
Output:

========
Resistor
========
Value: 1.0 Ohms 1%

Color Codes

Color	X	XX
Black	k	bk
Brown	n	bn
Red	r	r
Orange	o	o
Yellow	y	y
Green	n	gn
Blue	u	bu
Violet/Purple	v	v
Grey/Slay	s	sl,gy

Silver	si	si
Gold	gd	gd

SMD Resistors

Syntax: ./parts.py rsmd Code
Gives ohm value of 3 and 4 digits SMD resistors (Yes it supports decimals).

Example: ./parts.py rsmd 472
Output:

============
SMD Resistor
============
Value: 4.7 kOhms

Capacitors

Syntax: ./parts.py cap Code [VoltageCode ToleranceCode]
Gives capacitance value of ceramic caps with support of voltage and tolerance.

Example: ./parts.py cap 104
Output:

=========
Capacitor
=========
Value: 100.0 nF

Example: ./parts.py cap 104 1H B
Output:

=========
Capacitor
=========
Value: 100.0 nF
Voltage: 50V
Tolerance: 0.1 pF

Part Search

Syntax: ./parts.py part PartName
Searches online for descriptions and datasheets of a component. PartsPy lists 4 matching or closely matching components.
The results are parsed from alldatasheets.com. This website exists thanks to advertising and donations, please consider the latter.

Example: ./parts.py part ATMEGA328P-pu
Output:

===========
Part Search

Conversion

Syntax: ./parts.py conv value[prefix] [toPrefix]
Converts a value from one unit prefix to an other one. Indicate 0 if you want to convert to the base unit.

Example: ./parts.py conv 2k 0
Output:

Result : 2000.0

Example: ./parts.py conv 222u n
Output:

Result : 22000.0 n
