New Release For EAGLE CAD with PCB Alignment Tools


https://www.electronics-lab.com/new-release-eagle-cad-pcb-alignment-tools/

Since Autodesk acquired Eagle CAD, big changes have been made to Eagle CAD. Regardless of the new licensing system using subscription model, which was a subject to criticism by a lot of users, the new management of Eagle from Autodesk has successfully added a lot of demanding features that old team failed to bring out. […]

Simple circuit indicates health of lithium-ion batteries


https://www.electronics-lab.com/simple-circuit-indicates-health-lithium-ion-batteries/

Fritz Weld @ edn.com proposes a simple circuit to check li-ion battery health. He writes: Lithium-ion batteries are sensitive to bad treatment. Fire, explosions, and other hazardous condition may occur when you charge the cell below the margin that the manufacturer defines. Modern battery chargers can manage the hazardous conditions and deny operation when illegal […]

Exploring Eagle CAD ULPs #6 – Group-aps_v4.ULP Autoplace by Group


https://www.electronics-lab.com/exploring-eagle-cad-ulps-6-group-aps_v4-ulp-autoplace-group/

Welcome to the 6th post of the “Exploring Eagle CAD ULPs” series. Each post will be discussing one useful ULP in Eagle CAD. “ULP” User Language Program is a plain text file which is written in a C­-like syntax and can be used to access the EAGLE data structures and to create a wide variety […]

Fast Single-Pixel Camera


https://www.electronics-lab.com/fast-single-pixel-camera/

Compressed sensing is an new computational technique to extract large amounts of information from a signal. Researchers from Rice University, for example, have built a camera that can generate 2D-images using only a single light sensor (‘pixel’) instead of the millions of pixels in the sensor of a conventional camera. This compressed sensing technology is […]

Raspberry Pi Publishing MQTT Messages to ESP8266

Rui @ randomnerdtutorials.com tipped us with his latest tutorial. He writes: In this project you’ll create a standalone web server with a Raspberry Pi that can toggle two LEDs from an ESP8266 using MQTT protocol. You can replace those LEDs with any output (like a relay that controls a lamp). Raspberry Pi Publishing MQTT Messages to […]

StromPi, The Uninterruptible Power Supply for Raspberry Pi


https://www.electronics-lab.com/strompi-uninterruptible-power-supply-raspberry-pi/

It seems evident that the Raspberry Pi and its clones have filled an enormous hidden need. The digital performance of such micro-computers is exceptional as long as they are used without any special dependence on power requirements, that is to say near an electrical outlet with power! Faced with the vagaries of the analog world, […]

Robot Core – The Ultimate Raspberry Pi Robot Controller


https://www.electronics-lab.com/robot-core-ultimate-raspberry-pi-robot-controller/

The Robot Core, which is a robot control board for the Raspberry Pi and Arduino, brings many different elements into one awesome package. It allows you to efficiently control motors, servos, and read sensor data without needing 3-4 additional boards to hookup. Several Robot Core boards can be connected together in a linear series to add even more […]

Know your Tool – Optimize C Code for microcontrollers


https://www.electronics-lab.com/know-tool-optimize-c-code/

One of the talks in the “Embedded Linux Conference 2016” was about best practices to optimize C for microcontrollers. This talk deserves to be mentioned to Electronics-lab readers. The presenter Khem Raj worked on Comcast’s (broadcasting and cable television company) reference design kit for STB, Gateway and IoT platforms. We will cover some important points […]
