When I was 12, I built my first speaker out of a shoebox. It sounded terrible but I loved the process of building my own stuff. Flash forward to 2010 and my career as a location sound mixer. I needed a portable, yet very rugged battery powered speaker and I had no choice but to […]

Every guitar player desires it: The “perfect” sound! The components for it are: SOFT skill of the player mojo, soul, heart (name it the way you want, but essentially you can’t buy it -> You have to have it!) HARD the guitar (the wood, the strings,… -> The Hardware) for electric guitars: The amp/speaker unit

µGFX is a library to interface all kinds of different displays and touchscreens to embedded devices. The main goal of the project is it to provide a set of feature rich tools like a complete GUI toolkit while keeping the system requirements at a minimum. µGFX can either be run on top of an operating

If you have an application, where you work with kilovolts and you need a suitable diode, we have a solution for you. It´s not a quite common thing, to find a diode with a reverse voltage of more than 1000V in your “home-drawer stock”. But you develop a device, requiring a diode with a substantially

This tutorial provides a guide on how to set up an Arduino to measure the capacitance of a capacitor. This can be useful if the capacitor is unlabeled or if it is self-built. Capacitance is an object’s ability to store an electric charge. Reasonably, this object is referred to as a capacitor. A capacitor that

An alliance led by IBM Research, together with New York academic institution SUNY Polytech and with Samsung and GlobalFoundries, has produced 7nm (nanometer) node test chips with functioning transistors. Continuing semiconductor scaling down to feature sizes of 7 nm is expected to yield further gains in performance, and lower power levels, but in IBM’s words,

Pleasant actuation characteristics and reliable features of a push button switch Marquardt series 1840 make it attractive for all applications where you require control by a push. Classic push-button switches are favorite for many decades, maybe also because they´re well known already from the beginnings of electronics. Probably, a nostalgia is not the only reason

So recently I got a Raspberry pi and a 16×2 character LCD screen , I thought , lets make a simple game that can be played on the lcd. my first instinct was to code directly for the lcd on the pi , but as I started coding I realized that the clutter of having

If sensitive analog systems are run from one supply without the sufficient bypassing to eliminate noise, undesired degradation in a system’s performance will result. This application note provides insight into suitable techniques to overcome this roadblock. For more detail: App note: Eliminate noise through proper supply bypass filtering

In my last couple of blog posts, I did a brief overview of the EnOcean Pi sensor kit from Newark and demonstrated how to compile and run the example code using a Raspberry Pi. In this blog post, I will show a real world example – a four-channel remote control built using the EnOcean Pi
