Motor Drivers in Elektor Labs

Electric motors are everywhere, and drivers are needed to make them spin in a controlled way. At Elektor Labs we regularly test and try motor drivers and we also roll our own. Here is a short overview of what we are currently looking at.

Free Article of the Week! RGB Digit Clock

What do you pick when you want to design “something” with a vintage or modern display? A clock of course! This is our first design with ’RGBDigits’ multi-color 7-segment display devices. With a BME280 breakout board (BoB) attached, the project will also cheerfully display temperature, humidity and air pressure.

Elektor Labs Summer Contest 2019 - The Winner is...

To get us through the hot European summer of 2019 we asked you to show us your home lab by posting one or more photographs at Elektor Labs. Of course, taste is personal and all that, but we made Elektor staffers vote and obtained a unanimous winner. Read on quickly to find out if it is you…

Show Us Your Home Lab and Win More Gear to Clutter It With

Summer is halfway now (at least in parts of Europe), meaning that it is time to start our yearly Elektor Labs summer competition. The subject of this year’s summer competition is all but original, but at least it's easy to participate. All you have to do is post a picture of your home lab. By doing so you qualify to win an Elektor Store voucher worth €100!

Bright Flashing LED – traditional analogue...

Bright Flashing LED – traditional analogue...

A flashing LED? What is so special about that, you may well ask yourself. A microcontroller plus a handful of discrete parts, and Bob's your uncle – isn't it? Still, many readers love analogue electronics and so we present a variant that is built entirely from discrete parts and hopefully triggers your own experimentation!

Create a red-light district with darkroom in the backroom of your house

Create a red-light district with darkroom in the backroom of your house

At a time of digital photo cameras sporting many millions of pixels and colours and incredibly powerful image processing software, it's hard to imagine that there are people around who spend hours in a darkroom dipping their fingers in poisonous chemicals to develop monochrome negatives and positives? Yet there are, as is proven by this project on Elektor Labs.

Build an Electronic Die without Dots

Build an Electronic Die without Dots

Tired of counting the dots on dice? Then use this circuit instead. Its 7-segment display shows in an unambiguous way the value. Easy-to-build, based on an ATtiny2313 microcontroller and programmed in Bascom. Pressing the push-button will roll the die until the push-button is released. A random number from 1 to 6 will then be shown. A simple way to play quietly during the evenings when the children are in bed.

Build a digital music platform or use it for something else

Build a digital music platform or use it for something else

We start 2019 with an Elektor project that although almost five years old still is interesting for (music-making) microcontroller enthusiasts. Why? Because the J²B Synthesizer is a flexible open source and hardware platform with many features and possibilities that can easily be transformed in something other than a music synthesizer. It even comes with an enclosure.

Build a GPS tracker for ultra-endurance cyclists

Build a GPS tracker for ultra-endurance cyclists

Ultra-endurance cycling races with distances of several thousands of kilometres are becoming more and more popular. During such races cyclists ride for at least 16 hours a day. Some of these races require validation by a GPS track but how to keep it up and running all the time? The purpose of this project is to build a very low-power, simple GPS tracker that can run unattended for days at a time on a single battery charge.
