Awesome I'm studying a BEng in electrical and electronic engineering. This will help. :-)

Very poor compared to IPhone version For an electronics toolbox it's missing ALOT of features that the IPhone version has. Elektor has "thrown" this together and made no attempt to make it graphically appealling (again unlike IPhone version). If I could get a refund I would. Wait until Elektor sort out an update, disappointed so far...

You cannot compare this tool with the IPhone version because there is no IPhone version.
Only the name of the app was the same of the IPhone version that's why i changed the name to
Elector Analog Toolbox.
This app is GREAT! I use it almost every day. I love showing it to engineers and ham radio friends.

HARDWARE REQUIREMENTS:

Designed for high-density screen devices, tablet or large screen device recommended for best experience.

* For older devices with low screen densities (which have lower heap size), if you get low-memory warnings, please disable dark-background in prefs screen and work with SMALL or MEDIUM sized schematics (minimum 32MB of heap).

Basic Features:

* Schematics in SMALL:720x480, MEDIUM:1080x720 and LARGE:1920x1080 sizes.

* Free pinch-zooming and panning of the canvas on all editing modes.

## Schlage Electronics How-To

Allegion

1

This app will make it easy for you to view several technical support tools for many Schlage commercial electronic security products. Whether you're at the door and can't remember a programming step, installing a lock on a door and need to know how to insert the key cylinder, or planning your site and need to know how far apart you can install components, this app can help you right at the moment you need it.

It provides direct access to the How-To Videos from the SchlageSecurity YouTube channel. Today, our videos can be difficult to locate on a mobile device, and this app provides simpler access to them. It also allows you to access product documentation, including datasheets, installation guides, and user guides for AD-Series and CO-Series products. Simply browse through the menus to find what you're looking for. Additionally, you can call our customer care line directly from this app.

Please note that some documents, such as installation guides, are between 2-6 MB in size and may take several moments to download. Most of the content, including the user guides, are much smaller and will download quickly over a 4G (LTE), 3G or good Wi-Fi connection.

We hope that this app can make your day easier by getting you the information right when you need it, where you need it, on the phone in your pocket. We’re also looking for ways that we can improve this app to better serve you. If you'd like to leave us feedback on the app, we'd love to hear from you! You can use the option in this app to Send Us Feedback via e-mail, or provide a review in the store.

## DC Theory Calculator

DC Theory Calculator is an easy to use app for electronics students and enthusiasts of all ages. It will calculate Voltage, Resistance, Current and Power using formulas such as Ohm's Law. Enter any two known values (Voltage, Resistance, Current or Power) and hit Calculate. The two unknown values will be calculated for you. This app will also guide you with your own calculations by displaying the actual formulas used.

## Resistor Color Code

This is by far the fastest and most easy Resistor Color Code calculator.

Calculate resistor value by selecting the band colors.

Or Reverse:

Enter a resistor value and find the color code.

If the value is not an standard E-series value the two nearest values are shown.

* 3, 4, 5 and 6 band resistor support *

If the resistor has a standard E-series value then also the E-series (E3, E6,E12, E24, E48, E96, E192) number will be shown.

## SWR Calculator

Coupler Directivity Calculator is used to calculate the minimum and maximum values of Reflection Coefficient, VSWR, Return Loss and Mismatch Loss.

The Directivity Error Calculator shows the accuracy of a reflection measurement of unknown impedance. It bases its readings on the directivity of the coupler used for the measurement. It is also a convenient way to convert a reflection coefficient to an equivalent standing wave ratio (SWR), return loss, or mismatch loss.

## Black Screen Burn-in protector

This app gives you only a black screen. It is useless for normal android devices.

It works as a burn-in protector for plasma and Amoled Screens.

On some TV Sticks (mk808) you cannot dim the TV screen and the screen time out is also not working.

And if you only want to play only music (Spotify) then it could be possible that the screen will burn-in.

Tap Anywhere on the screen to exit the app.
