Add Lidar Vision to Your Robot

Techniques that used to be available for multi-million defence projects only are becoming more affordable. Take lidar, short for Light Detection And Ranging, a 3D laser scanning method for mapping the environment. Initially intended for satellite tracking, today you can buy a miniature lidar for under €100. Add the software from this project and away you go (your robot, of course).

A Close Look at the congatec conga-JC370 3.5” JUKE SBC

With the conga-JC370, congatec adds the 3.5” form factor to its product range. Built around the eighth generation Intel Core U-series processors the new cores promise a performance increase of up to 40% in multi-threaded applications. We had a close look at the board.

Build a Power Monitor with Bluetooth and Android App

This is a typical one-thing-leads-to-another (OTLTA) project. It started by reading an item about a new component in the Elektor newsletter and it ended with a circuit design with Android app to check the power consumption of a device on your smartphone. Communication between the smartphone and the energy monitor is over Bluetooth.

How-To: Calculate the Prospective Short-Circuit Current or PSCC

The prospective short-circuit current (PSCC) is the maximum current that can flow through a shorted electrical circuit. The PSCC value is needed for selecting devices like circuit breakers and fuses to protect the circuit. So how does this work?

André-Marie Ampère Never Went to School - a Short Biography

Volta, Ampère, Ohm — we use their names all the time, but what do we really know about the people that laid the foundations of modern electronics? In this article we will (briefly) explore the life of André-Marie Ampère.

Build a Music-Based Growth Stimulator for Tomatoes

Recent studies suggest that exposing living creatures of all sorts, animal or vegetal, to music has positive effects on their development and well-being. Inspired by this idea, the author developed a system to stimulate the growth of tomatoes inside a small greenhouse.

Build a Cheap ESD Human-Body Model Simulator

Electrostatic discharges (ESD) can destroy electronic devices or cause system malfunctions. Professional ESD simulators are expensive, but a cheap high-voltage generator combined with a small microcontroller can be a good alternative. The circuit presented here conforms to the Human-Body model and will work more reliably than your finger(s).
