I've wanted for a long time to have electrical/electronics calculators next to me on the benchtop when I'm working with electronics. For the same reason why I don't like USB (i.e. PC based) instruments like scope, logic analyzers, etc. I don't like online calculators to find out quickly right resistors value for certain opamp gain, output from voltage divider because I have to move back and forth from one table to another. Other possibility will be to place PC next to my D.U.T. but I don't want that only keyboard occupy a substantial area of already crowded benchtop. MicroPython (MP) scripting starts to changed that and first results are already here. Currently I don't have a time to shot a video about that but few screenshots could help you to get an idea.

First, the BB3 SD card file manager are changed to present files with thumbnails, then when you enter Scripts subfolder, first comment from .py file could be displayed as description, and finally we made a first step toward integration of MP scripting and GUI editing in EEZ Studio. The underlying mechanism is SCPI, and new set of commands was added that MP could interact with custom made pages (created in EEZ Studio).

So far, we have the following calculators available:

• Op-amp (non-inv, inv, differential and diff. simplified)
• Voltage divider
• R/L in parallel and C in series
