Eagle CAD Tips and Tricks: Most hobbyists and many professionals use Eagle CAD as a daily tool in designing schematics and laying out PCB. I’m going to share with you the most important tips and tricks for using Eagle CAD, which make my work much easier and faster. Tip #1: Keep One Hand on the Keyboard, One on the Mouse I see a lot of friends and colleagues use the mouse as their main tool for routing and selecting tools in the sidebar, but it’s much easier and faster to use the command line whenever you can. By using your...

Introduction to Capacitive Touch Sensing: In this article, we will take a detailed (but not too detailed) look at the electrical principles that allow us to detect the presence of a human finger using little more than a capacitor. Capacitors Can Be Sensitive Within the last decade or so, it has become difficult indeed to imagine a world without touch-sensitive electronics. Smartphones are a prominent and ubiquitous example, but of course, there are numerous devices and systems that incorporate touch-sensitive functionality. Both resistance and capacitance can be employed as a means to achieving touch sensitivity; in this article,...

MicroFAT: A File System for Microcontrollers: File systems can be great for handling data and organizing memory, but most file systems require large amounts of memory. This is where MicroFAT comes in! The Problem with Standard File Systems Microcontrollers are becoming the core of many electronic projects for hobbyists and the norm in electronic design overall. With the complexity of projects increasing and the introduction of the IoT, it will not be long before micro users will need to also increase the capabilities of microcontrollers.  A common use for microcontrollers is to log data from sensors such as temperature, humidity,...
