RF-Toolbox update 6.05.01 and new data update

A new App update 6.05.01 and data update is available for RF-Toolbox

I almost thought that this new update 6.05.01 will never come out or along with the next update I am already working on.

This update is not just a preparation for iOS 7 but also contains the following new tools:

■ Passive cooling calculator
■ PTC / NTC Temperature Resistance conversion
■ AC Ohms law tool
■ Zener diode circuit calculation
■ Constant current source tool
■ ASCII Table

Some existing tools have been extended such as:

■ The OpAmp Tool now can also calculate an Instrumentation OpAmp circuit
■ The number system tool now also supports IEEE floating point numbers

With this update, it is also possible to copy output results (regardless if this is text or a number) by long-tapping the value. This way, you can easier transfer results from one tool to another or even to another App, a mail or notes.

Finally, as usual, many other things have been changed and corrected under the hood.

PLEASE NOTE: along with this update, also a data update has been released. Please don’t forget to install the data update by using the “Check for update now” button in the settings screen of the App. The order of the installation (data update or App update) does not matter.

Most of these changes will also apply to the next version of Electronic Toolbox but there is much more to come so stay tuned.

Thanks again for all your mails and support.

Kind regards,


New dedicated website – new ideas

New website

I must admit that I am really overwhelmed with emotions about some of your mails and App reviews. Many many thanks! This really helps me to keep up my work and inspired many new ideas. I wished I would have 48 hours a day to implement all of that much quicker.

As you may have seen already, there is now a dedicated website for Electronic Toolbox and RF-Toolbox and they are no longer part of

This will better suit my future plans with Electronic- and RF-Toolbox. There is much to come over the next months so this new dedicated website (and .de) will allow me to better inform about these ideas in the future.

Thanks again for all your mails and support.

Kind regards,



Just keep you updated

Dear users of Electronic Toolbox,

I just like to keep you updated about my current development activities. I have already a lot of data prapared for a data update (based on your requests and some own additions) which would be ready to be sent out. However, I would like to send it out along with the next App update. This App update contains – like always – some great enhancements and new Tools.

As you know, Apple has sent out Beta versions of iOS 7. The good news is, that the current version of Electronic Toolbox already runs on iOS 7 without problems.

On the other hand, I like to implement some changes for the next update so that Electronic Toolbox can benefit from iOS 7 and so it can also be officially maked as iOS 7 compatible. I am corrently working on that but have to wait releasing this update until iOS 7 has been officially released by Apple, which should not take too long anymore.

Please be assured that I will keep backward compatibility as best as possible even though this takes often much more development effort than beeing forward compatible.

So far, it looks as I can keep Electronic Toolbox running from iOS 5 up to iOS 7.

I will keep you updated,

Kind regards,
