pyengineer is a collection of scripts that are useful for electronics or hardware design. It is a wsgi-enabled Python application and has a GUI in your browser. The idea is that you can adapt the software to your workshop; for example, you tell pyengineer in the configuration file what resistors you have at hand (configuration.json) and then, inside the UI, you can for example say that you'd like to know what combination of parallel resistors (that you have at hand!) make a certain value.

One of the key concepts is that additional tools (i.e., "plugins") should be extremely simple to add and test. This is why they're all entirely self-contained in one single file each. There's some boilerplate code inside pyengineer which you should never have to touch because it should be sufficient to simply write everything in that one plugin file.

Just type

$ ./wsgi.py

On the command line and it should come right up:

 * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
 * Restarting with stat
 * Debugger is active!
 * Debugger PIN: 194-208-269

Then, go to the shown address and it should work.

Here are some screenshots of how PyEngineer looks like.

Writing a plugin is extremely easy: Just copy any ".py" file inside the "plugins/" directory to a file name you like. The only two things you will have to change is: The plugin _ID (which should be a random type-4 UUID that you create) and the placement inside the menu (_MENU_HIERARCHY). Then you're ready to go. pyengineer will auto-discover that new Python file in the plugins/ directory, integrate it into the menu and show it to you. You can also run it without and UI from the command line. This is useful for testing and all present plugins can do this:

$ python3 plugins/BasicDeunify.py
Request <default>:
{
    "input_value": "123.456k",
    "significant_digits": "4"
}
Response:
{
    "significant_digits": 4,
    "value": {
        "flt": 123456.0,
        "fmt": "123.5 k"
    }
}



123456.000 = 1.23e+05 = <strong>123.5 k</strong>
