We're living in a golden age of software, where many useful programs are available – for free! Let's survey some of what's out there that just might interest an engineering crowd like the EDN  community. I can't offer personal opinions on most of these packages, but I expect to hear back from you after you've test driven a few. Instrument control I recently learned  about PyVISA, a Python library for talkin ...

Castellated Edges 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. While we don’t offer full support for castellations, they can be fabricated if you don’t mind a few minutes of rework and verification of the PCBs. Design Considerations It’s helpful to include a fallback hole near the edg ...

Mechanical keyboards with reduced key counts are all the rage these days, but while those streamlined input devices might look cool on your desk, there are times when the traditional number pad or navigation keys are quite handy. Rather than just going without, [Mattia Dal Ben] decided to put together his own mechanical auxiliary input device for when the main board just isn’t cutting it. [Mattia] is callin ...

Toys are great for keeping the kids amused at play time, but oftentimes its difficult to get them to understand the importance of tidying up after themselves. It would naturally be ideal to have some manner of robot to help in this regard, and [Paco Garcia] might just be leading the charge in this area. [Paco]’s project involves combining a robotic arm with computer vision tools in order to allow it to pick ...

In this article we are going to see about what is PCB board and some types of PCB board. A PRINTED CIRCUIT BOARD (PCB) mechanically supports and electrically connects electronic components or electrical components using conductive tracks, pads and other features etched from one or more sheet layers of copper laminated onto and/or between sheet  layers  of  a non-  conductive substrate. Components are genera ...

ICStripBoard is a innovative cheap tool to enable rapid prototyping of surface mount integrated circuits (IC’s) and allow their usage in prototype electronics projects. Inline surface mount IC’s come in a Variety of packages which are different sizes and these Printed Circuit Boards (PCB’s) have been designed to accommodate the majority of IC’s. Available in the four standard IC pitches (space between IC pi ...

By: Alex Danovich,President San Francisco Circuits We live in an exciting time where we see a resurgence in electronics as a hobby. Mass production has wiped out a generation or two of kids learning to build radios from scratch with their mom or dad. In the good old days, not sure when, you had companies like Heathkit walk you through building a full size color TV at home, for example. “Yes, I made that!” y ...

Not many people know, but in some smoke detectors, radioactive materials play an essential role. Today I will present one of those devices, and my -successful- attempt to reverse engineer it and get the circuit diagram. Those smoke detectors use a small amount of Americium-241 (chemical symbol: Am) obtained in nuclear reactors as a decay product of Plutonium-241. Am241 emits mainly alpha particles, but also ...

Online circuit simulators are getting more popular day by day. Electronics hobbyists, as well as professionals, use circuit simulators often to design and check circuit diagrams. The best thing about online simulator is, you don’t have to install anything at all on your PC or laptop. All you need is a browser and a stable internet connection. Work from anywhere just by opening the online circuit simulator w ...

PCB Quality Control Almost every electronic device now a days is powered by one or more printed circuit boards (PCBs). Simply, we can say PCBs are the heart of electronic devices. Hence, the quality and reliability of PCB are directly correlated with the quality and reliability of the electronic device. For example, flaws in defining characteristics such as size and power consumption not only directly impac ...
