Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

I found this today while calculating a potential-divider:

Electronics Assistant

Does all sorts of common Ohm's law calculations and capacitors etc.

Quite useful.

good find.

I use two app-based calculators on my android phone:

Unit Converter - a, erm, unit converter ... for engineers  https://play.google.com/store/apps/details?id=org.wopnersoft.unitconverter

and

ElectroDroid for electronics-based calculators. Doesn't do everything but covers all the usual and seems to get reguklar updates for the pin-out and resource libraries
https://play.google.com/store/apps/details?id=it.android.demi.elettronica

there are stacks of this sort of thing out there but these two I have settled on as filling most needs

I have Electrodroid installed, but I usually just use the HP-15C app from https://hp15c.com/

Not a "electronics" app per se, but it got me through my electronics classes in college. :)

Google "Daycounter.com".
There you will find an endless list of calculators for a great many things.

For anyone who evolved along the rpn hp25 hp41c hp42s path you probably already use the Free42 app, but if not it is absolutely worth tracking down as a GTO general purpose calculator with electronics abilities.
