In the past, I’ve  always seen small circuits of copper with no silk screen or solder mask on top of it and as a PCB designer I have always the question in my mind: What is it for? — I’ve never needed them before! As I can find them in Arduino’s PCBs as well, I decided to open...

SeeedStudio has published a PCB design manual to help makers and engineers design better PCBs. The guide covers many aspects of PCB design for manufacture summarizing the experience of their PCB service over the last 9 years. PCB Design for manufacture -...

Researchers from AMBER (Advanced Materials and BioEngineering Research) and Trinity College (Dublin), together with the TU Delft have succeeded in producing printed transistors, which are made solely from two-dimensional nano materials. These materials have characteristics with...

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...

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...

@ oshpark.com: Castellations are small plated edges, typically used for making circuit boards into small pcb modules. These are often seen on wireless modules, such as the ESP8266-12E. Castellated PCB Edges -...

Pieter @ piconomix.com tipped us with his latest build. Check it out on the link below. I recently had to create a programming jig for an ATmega328PB based board. 1mm diameter test pads were placed on the bottom of the PCB to give access to the ISP pins. Normally one would add two...
