8.1.0
2017-08-08
New File Manager! Simply save and load your calculations!
The EE ToolKit now features an integrated File Manager. For every tool there is now the option to save as many calculations as you want to and re-load them at any later point in time. Just tap on the folder icon in the sidebar menu and the browser will appear. After saving, the data is stored locally in the App and also synced in iCloud, so it even transfers to your other devices running the same App.
Like for the universal build of the EE ToolKit App (that's the free version with In-App purchase to PRO), you can save a calculation on your iPhone and later on open the same calculation on your iPad or vice-versa.
Or if you run the 'EE ToolKit for iPad' version on your iPad Mini and on an iPad Pro, these two will sync all saved calculation data. But please note that this feature is tied to your iCloud account, your Apple-ID. You cannot transfer calculation data between different iCloud accounts!
Editing is also straightforward. In the File Manager, just swipe left on a row and you will be given the option to rename a calculation, or to delete it.
Other Changes:
• updated links to NXP datasheets. NXP is now Nexperia.
• iPad menu structure changed (now with sidebar just like on iPhone)
• other improvements and smaller fixes
Thank you very much for using the EE ToolKit! If you have a moment, please leave a review in the App Store. With this, you are really helping a lot so we can further develop and improve the App. Thank you so much! - tom

7.0.2
2015-12-13
The brand-new EE ToolKit Pro 7 for iPad is here! Yet again I have spared no efforts and implemented a great amount of new features and this time also settings. You can now configure between the American style or the European IEC resistor symbol type. You can even set V or U as your preferred voltage character. And this works for all the schematic drawings and the formulas all over the App!
In order to make that happen I had to re-design all the graphics and at the same time, of course, I improved them as well. I really hope you like the new look as much as I do.
I am also introducing a brand new Favorites page! Each tool or calculator can now be selected as Favorite and it will show up in the Favorite page. This provides a new and very quick access to your most favorite tools. The order of the Favorites can be rearranged, if required.
A Lot of new tools have been added and the existing ones have been improved. One of the new tools that clearly stands out is the new resistor circuit recommender. So, imagine you need a 1% resistor value but you have only E6 or E12 values available. Let's say you need 35.7Ω and you need it now. No time to order it. So, ... just ask the tool! No manual calculation required!
The LED Tools have been completely re-designed. There is now a picker, which lets you pick the typical forward voltage for different LED type colors. Three more tools have been added. One of them is an application example with the TI TPS61165 where you can control the brightness of a LED display backlight with a PWM. This is both great for understanding PWM in general and for trying it in a real application like in this backlight control.
SUMMARY OF THE NEW FEATURES:
Ω Support for iOS 9
Ω Optimized and improved all graphics and formulas (especially for the iPad Pro)
Ω Added the resistor circuit recommender
Ω American style / IEC style resistor symbol switch
Ω Added all new Favorites page
Ω Added Iref to the dB Converter Tool
Ω Improvements to the Wire Ampacity tool (adding also AWG as input field)
Ω Accuracy fixes to the Resistor Color Code tools for values < 1 Ohm

- LED with constant current source
- Display LED backlight control via PWM
- Visible Light Spectrum browsing
Ω Frequency Generator specific:
- added the BPM feature (pulsed audio out) to the frequency generator. You can now pulse the generated audio within a range is 1 - 600 BPM!
- A new Phase-Out setting is now available. Configure the phase out (phase shift of 180 degrees) for each channel individually. Note that once phase out is activated for a channel, the setting is also visible on the main frequency generator and the sweep page (red text). Phase Out is not available on the Noise page!
Please don't forget to also rate this new version of the EE ToolKit PRO. This is very important for me. Thank you so much!
6.1.3
2015-03-22
This is the brand-new version of the EE ToolKit Pro for iPad. It is yet again a very big release, loaded with tons of new features, extensions and improvements. I have put a lot of hard work into it and I really hope you will like it as much as I do!
Thanks very much to all the users that have sent me their feedback. I am happy to say that I have implemented almost all of your requests. But if you find something missing, please know that I have it on my todo list. It will come.
RELEASE NOTES:
Ω added a brand new Audio Scope. The scope supports a buffer mode, rolling mode and an FFT view. Please note that you have to allow access to your device’s microphone so this can work properly.
Ω added a brand new tool to the Frequency section: a pitch detector! This tool lets you detect and show the fundamental frequency of a captured microphone audio input. This is achieved by running an FFT over the input signal to filter out the part of the signal with the highest amplitude.
Ω the decibel tools have been redone completely! There are now 4 sub-tools in total and a very powerful decibel cross-converter with browsing through decibel nomograms.
Ω the RMS tool has been redone completely! Now 10 different waveforms are supported.
Ω added 3 new tools to the RLC section. You can now search a resistor, capacitor or inductor value for a given cut-off frequency (for RC, RL, LC circuits).
Ω added 3 new tools to the RLC color code section. Type in SMD codes directly and the tool will convert to the actual component value, the color code and present it on an actual component.
Ω added 3 new tools to the Basic Circuits section. Find the missing resistor, capacitor or inductor value of a series or parallel circuit for a given total value of the series or parallel circuit.
Ω fixed the Invert / Revert bug for the Number Systems Tool (did exist only on the 64 bit architecture)
Ω corrected the formula for serial impedance (RLC section) - the calculation was actually correct before, but the formula was shown wrong.
Ω the transistor calculators now show voltages and currents at each significant point in the circuit.
Ω added the Clear button to all the text fields
Ω Frequency Generator
-all the frequency presets can now be customized (a new popup menu allows an easy customization of the presets. Just enter a custom frequency and tap on any of the preset-fields to save it).
-added a new view for custom configurations. You can now save any sound configuration there and play it back any time later. Configurations can be rearranged and also deleted.
-fixed an issue with the sweep timer.

6.0.4
2014-10-25
The brand-new EE ToolKit Pro 6 for iPad is here! The app has now gained something so great and amazing, I trust you will like it as much as I do. I have implemented an amazingly great multi-functional keyboard! Input of values with units, E Series, tolerances, slider ranges etc. was never easier! A multi-functional keyboard like that is really perfect for an engineering tool like the EE ToolKit Pro! Try it yourself!
In order to make this happen I had to change a lot under the hood and implement many parts of the app from the ground up. But it was totally worth it. In addition also the conversion of units for the calculated results is now more simple and convenient than ever.
Units for calculated results are set to "Auto"-convert per default. This means, if the value of a resistor is for instance 47000Ω, the tool automatically converts it to 47kΩ. This can of course be configured completely flexible.
I have re-structured, graphically improved, enhanced the UI and on top of this, added lots of new features:
Ω support for iOS 8
Ω complete update of the component Color Codes:
- added color picker to the resistor, capacitor and inductor color codes.
- added 5 band capacitor tool
- greatly improved look and feel of the complete color code toolset

About the big update that was done for Version 3:
Version 3 of the EE ToolKit Pro for iPad is the most extensive update to an App that I have ever made. The App has been improved so much, it is basically a re-write of the whole thing. I have changed the UI completely. All the tools are now structured in a very clear and easy to find way. All the graphics have been updated. All the info pages have been greatly improved and implemented in a faster accessible way.
I have added more then 50 new tools to this new version.
After a long time of hard work I am now very happy to release the new version of the EE ToolKit Pro for iPad to you.
I hope you like it!
