What's New

!!! THE EE TOOLKIT GOT MASSIVELY UPDATED !!!

To everyone using this App! Thank you so much for your awesome, encouraging feedback over the years. I am working hard to implement all your requests and I am proud to release this new version to you now. It has dozens of new features, improvements. See yourself:

Ω German language support finally available.
Ω improved the BIN, DEC, HEX, OCT Converter. It is now possible to set and clear each Bit from a 32-Bit String individually
Ω New Non-Linear Resistors section with theory and several application examples.
Ω Greatly enhanced the LDO Calculator. Option to switch in a third resistor R3 in parallel to R1 to further fine-tune the output voltage. Well, Rene – this is for you
Ω improved error messages for the LED tools
Ω 555 Timer IC Comparator example bugfix. Hysteresis was not working properly.
Ω fixed LED control for 555 Astable Timer (was inverted with regards to the Duty Cycle)
Ω Access to Sub Views for LEDs, Trace Impedance, OpAmp and Par/Ser RLC Circuits got improved. Now faster & cleaner.
Ω Some graphics got updated (home background), main App Icon, icon updates for the tools, some polishing, some smaller improvements

Very useful tool. Lots of different menus. Particularly like the access to device data sheets.

Engineer
Excellent! Well worth the purchase. Very handy to have around for reference.

Super!
Finally there's an Electronics App that's exactly what I was looking for.

Fantastic!!!
No applications are more complete than this application, very user friendly as well.

Very interesting とても興味深い
I'm a circuit engineer of printers. This App is very interesting.

Completa
Molto comoda e completa. Sarebbe perfetta se avesse anche le indicazioni relativi ai connettori XLR per uso audio. Consigliabilissima!

Elektronik App für Profis
Diese App ist wirklich Top. Ein absolutes Muss für Elektroniker und Bastler
