Panelization – using GerberPanelizer on Windows (Linux possible)

Arsenijs over at Hackaday.io writes: This tutorial was done on Windows. Authors claim it could also be used on Linux by using Mono, but I haven’t tried and don’t understand a lot about Mono to see what could be done. I am switching to Linux nowadays, so I’d be very grateful to anybody that’d make instructions […]

Build your very own drink mixing robot

Yu Jiang Tham designed and built his own bartender robot named Bar Mixvah, that is available on Github: I built a robot that mixes drinks named Bar Mixvah.  It utilizes an Arduino microcontroller switching a series of pumps via transistors on the physical layer, and the MEAN stack (MongoDB, Express.js, Angular.js, Node.js) and jQuery for the […]

Tutorial: Using Eclipse with NXP MCUXpresso SDK v2 and processor expert

Erich Styger from MCU on Eclipse writes: To me, software and tools are by far more important than the microcontroller. Because the silicon is a ‘one time kind of thing’, where the software has to be maintained and working over a longer time. And at least my software usually needs to be ported to a […]

Tiva and Stellaris Launchpad RTC usage in Energia

Vadim has posted a tutorial on how to use internal RTC of Stellaris and Tiva Launchpad boards in Energia IDE: For those of you who still have one of those old Stellaris Launchpads, I’m going to show how to utilize one of its most useful features – real time clock – in a simple way. Actually, the […]

ChipKIT based weather station using BME280 sensor module

A comprehensive tutorial on making a chipKIT based weather station using BME280 sensor module from Embedded Lab: BME280 is a fully integrated environmental unit from Bosch that combines sensors for pressure, humidity, and temperature in a tiny 8-pin metal-lid LGA package of size 2.5 x 2.5 x 0.93 mm³. Because of its compact size, ease […]

Guide for BMP180 barometric sensor with Arduino

A how-to on using the BMP180 barometric sensor with the Arduino from Random Nerd Tutorials: The BMP180 barometric sensor (model GY-68) is the one in the following figure (front and back view). It is a very small module with 1mm x 1.1mm (0.039in x 0.043in). It measures the absolute pressure of the air around it. It […]

Tutorial: RFID tags with the NXP NFC controller PN7120 and Eclipse

Erich Styger writes: Playing with RFID and NFC is definitely fun?, and they are everywhere! For a research project I’m exploring different RFID tags and solutions. I several types around for a long time, but never found the time to actually work on it, so last nightI thought I give it a try, and I […]
