Electrically Safe LED-to-Lamp Converter

Pico Technology’s 2000 series USB oscilloscopes have a fine “bandwidth” both in terms of “megahertz” and cost: from the £99 10 MHz entry-level 2204A with 8 kS (kilosamples) memory and 100 MS/s sample rate, right up to the 2208B which at £909 ex VAT brings 128 MS depth and 1 GS/s sample rate. Not forgetting MSO functionality.

The Arduino and Raspberry Pi have revolutionized the field of embedded systems design. One area of widespread applicability for both devices has been motor control. But if you would like to learn more about Arduino- and Raspberry Pi-based motor control applications, a quick search on the Internet will only complicate things. You’ll find thousands of motor control projects based on these popular platforms. The problem, of course, is locating high-quality, well-tested motor control projects from reliable sources, which is hard to do because do-it-yourselfers and students are uploading new Arduino and Raspberry Pi-based projects to the Internet each day. Fortunately, Dogan Ibrahim had the foresight to write a comprehensive book on DC motor control designs featuring the Arduino platform and Raspberry Pi Zero W single-board computer (SBC).

The YDLidar X4 is a very affordable Lidar that is mainly intended for applications in robots. The software is targeted at Visual Studio 2010 and there are demo applications for Windows and Linux. All necessary libraries are freely available, of course. The Lidar measures 360 degrees around and detects obstacles from 12 cm to more than 10 meters.

NeoPixel LEDs are cheap and easy-to-use RGB LEDs, digitally addressable. Example code, libraries and supporting content can be found easily everywhere. In the September-October 2018 issue of Elektor Magazine one can read the extensive description of an ESP8266 web server for NeoPixel LED strips. Both the PCB and the ESP module are available from our online store.

Taking full advantage of the Raspberry Pi’s open architecture, you can customise and program the NanoSound HiFi DAC. With the Volumio software or any other player software and the Infrared Remote Control, NanoSound gives you the best audio performance and experience you can expect from such an audio player.

The RPi doesn't actually need a push to boost its popularity. Nevertheless, this new way of providing a plug-and-play setup for this platform will substantially widen the circle of friends. Even the timidest beginner will find in it a comfortable environment for programming his own Pi-driven hard- and software. Many programming languages are available. For a start, tinker around with existing ready-to-go projects, and soon you will follow your own ideas.

Black Magic Probe – JTAG & SWD ARM debugger is a very small and lightweigh board designed for more efficient embedded programming. When you run into a problem with a program you are writing, the Black Magic Probe allows you to follow the execution step by step. Run your program in real-time and interrupt it at any step to inspect and modify CPU registers or variables or watch them as they change. You can also inspect the Function Call Stack and much more. You'll do the right things right in time! Instead of complex and expensive proprietary black-box tools, you’ll find openness, simplicity, and reliability. Forget about difficult to set up and maintain open source solutions.

Elektor Business Edition 4/2018 (Automotive) is now available. This issue features articles and interviews on a wide variety of automotive-related topics, including machine vision for auto applications, V2X communications, benchmarking IC development for automotive systems, simulation-driven design for automotive climate systems, and more.

Since 2002, David Henderson has been focused on developing small precision motion technologies that are lower power and less expensive than other products on the market. Today, his company, New Scale Technologies, is pursuing solutions for a wide range of applications, including laboratory automation systems and collaborative robots.
