The brand-new Electronics Engineering ToolKit Pro for iPhone is here! Yet again the update is a very big one and I am proud to announce lots of new tools, improvements and feature additions to you! I have put a lot of hard work into it and I really hope you will like it as much as I do!Now you can browse and access your datasheets, documents, measurements, schematics, etc. directly from your Dropbox or iCloud account. Built right into the EE ToolKit. Simple, direct access.I am also introducing a new Formula-Search Tool. Now you can search the complete formula database of the EE ToolKit. A summary view shows the formula and the related schematics (if available) and a direct link to the respective tool. Jump right from the formula into the calculation!I am also happy to present a completely new toolset all around examples and applications around Sequential Logic circuits. Eight new tools are available in this cluster, which help you to simulate, analyze and understand sequential logic components and circuits. These new tools have really turned out very great!And on top of all of this I have done a great amount of improvements and fixes and of course I have also implemented many customer requests. Thanks again so much for your awesome, encouraging feedback!SUMMARY OF THE NEW FEATURES: Function Generator News:- added dual function generator (handling the left/right channel individually)- updated the function generator with new settings- added logarithmic sweep to function generator iCloud and Dropbox integration: browse and access your documents directly from the built in Dropbox or Cloud account. Sequential Logic Tools: added a completely new toolset of eight great new tools with emphasis on Sequential Logic circuits and applications. PCB Trace Width tool is now split up in three separate tools (one of them for calculating the PCB trace resistance) Formula Search: new powerful search tool for searching the complete formula database of the EE ToolKit. New Tool for calculating the impedance of a coaxial cable added new components (PN2222A, 74HC165 and 74HCT165) added PDF view for the PWM LED tool the AWG tool now supports entry of diameter or cross-section area for the AWG conversion added foot/ft to the keyboard and unit selector added unit conversion for Volts to the dB calculator added improved automatic output formatting to the Ohm's Law calculator new magnitude of the phase velocity options for the wavelength calculation toolBUGFIXES- fixed accuracy for 4-band color code tool for values <1- fixed incorrect autofill of T and Pi calculator- fixed conversion error in the Wire Ampacity Calculator (for inch only / AWG was correct)- calculation of the pitch detector wavelength now corrected to speed of sound - pinout of DB25 was not visible in the universal app- Function Generator max Graph-Amplitude fix (was cut-off on iPhone 4S).Please don't forget to also rate this new version of the EE ToolKit. It really helps a lot to further develop and improve the App. Thank you so much!
