New RF-Toolbox update available – Happy Thanksgiving!

This RF-Toolbox update 6.08.01 includes the following changes and additions:

  • Resistor/Capacitor/Inductor combinations tool

This tool helps to create a certain value by calculating various combinations of serial or parallel connected components. This is especially useful if you can’t find a component with a certain value in your shack or if you need to create a value outside the E-Series standard.

  • 4-20mA conversion tool

This new tool converts values based on the instrumentation systems 4-20mA DC standard.

  • Negative value entering

For some input fields it was not possible yet to enter negative values. Now, the special keyboard has received a minus sign in the top bar.

  • Support for oz/ft² (Copper Plating Weight in oz)

Especially for the PCB trace calculation, thickness can now be entered in oz/ft² .

  • Calculator degree / radian support

The trigonometric functions like sin() and cos() can now calculate in radians and degrees and there is a new button which can be used to switch between these two. However, the degree button ° can still be used to convert values from degree to radians, thus when set to radians and calculating sin(45°) results in the same value as if the calculation is set to degree and entering sin(45) .


Update Version 6.07.01 for Electronic Toolbox available

Thank Goodness it’s Friday! as the new Electronic Toolbox update 6.07.01 is now available.

This update fixes some issues that have been reported such as the not working „Add to project“ buttons in some areas of the app and the inability to add folders in the organizer. Sorry for that.

Now, in the unit conversion tool, it is again possible to see all other conversions at a glance like in the older version. All possible conversions can now be observed by tapping on the selection below „Convert to:“. Thanks for this suggestion!

There is now a consistent way to decide which value should be calculated and which are the „given“ values.

As an example, in the Ohm’s law tool, let’s say you like to calculate Current and Power based on Voltage and Resistance. You can tap on the small button in front of the Current and Power fields. These buttons will then turn to have a small arrow indicating that these values will be calculated.

Now, it is also possible to tap at the location where you expect an input field in order to get the white input field for entering a value.

You will also notice a change in the user interface. I have changed several areas throughout the whole app so that it fits better to iOS 7.


Windows 8 update available now and iOS Version comming on Friday

Fortunately, the new Windows version of Electronic Toolbox was just released by Microsoft and the iOS Update will be available this Friday.

Lately Microsoft gave me a hard time to fulfill all requirements for the naming of screen shots on the Windows Store and several additional minor requirements. The good thing is though, that Microsoft takes Store approving serious – which is good, for you as customer as well as for me as developer and customer. I hate the lax or even not existing Google approvement procedure which causes many rubbish, non-working, faking and Trojan apps on the Android play store.

However, back to the Windows version, which includes many changes such as:

  • New NTC / PTC tool – New Raspberry Pi tool
  • New Constant current source tool
  • New AC Ohms Law tool
  • New ASCII Table tool
  • New Zener Diode tool
  • Instrumentaion OpAmp calculation
  • New languages for the User Interface: German, Italian, French, Spanish, Japanese, Chinese (Simplified and Traditional)
  • Updated Databases
  • Some changes for Windows 8.1
  • Some Bug fixes and many additional minor changes

The Windows version is available here.

iOS update

The iOS Update, as mentioned, will be available this Friday. It contains quite some fixes and internal improvements.
