With my new hobby, there came the desire to learn to build and design my own PCB. With that in mind, I began to use the open source ecad solution Kicad. Now I became interested in participating in this project, but, to compile the code you have endure a few challenges - you know, collecting the dependencies,installing them, choose the right branch whiche compiles down and so on. Here I want to show you my experience with that. ...
Hi there, finally this week the nandland go board I ordered from the developer Russell Merrick a month ago arrived. It took a detour due to some shipping problems, but this is not about that, so. I had to face quite a few obstacles to get this running on my Debian Bullseye. Serial Connection via USB First of all, to connect to the board via FTDI usb as suggested on Debian Bullseye you have to first add your user to the group 'dialout', this is done like below: ...
It is about time, to share another favorite of mine with you, and this is duckburg and the duck universe. I take the LTB (Lustiges Taschenbuch) Nr. 162 as an example from the golden era of the comic series "Lustiges Taschenbuch" Der goldene Totempfahl (The golden totem pole) In the story "Der goldene Totempfahl" english the golden totem pole, uncle scrooge is making a movie about his life, the story plays in the county of Dawson, where they are getting lost after a storm, they meet the indianer "großer Elch" english "big moose" and are searching for the gold nuggets big moose saved for uncle scrooge back in time. ...
Today I want to show you, how to connect to the DE10-nano board, the successor of the DE0-nano board. It is a bit bigger, costs nearly 300 bucks, but also supports Linux out-of-the-box. There is an Angstrom Linux installed on the SD-card. To connect to the board via the UART interface, power-up the board with the wall-wart,enter the sd-card to start the linux booting, and finally connect the micro-b usb cable (like shown below) with the PC. ...
So, you decided you want to learn fpga programming and have done the prerequisite from the introduction 0 as well as done the simple logic circuit via quartus’s bdf files. Today we want to show you how to figure out Quartus by doing another hardware equivalent of the hello-World program used in the software world - we do program a binary counter showing of by the LED array we have available on our DE0-nano board. ...
So, you decided you want to learn fpga programming and have done the prerequisite from the last blog post. Today we want to show you how to figure out Quartus by doing a hardware equivalent of the hello-World program used in the software world - we call it AndGate because it is simply that - an and gate feed by to push-buttons as input and a status-LED as output. This way we will make use of the Block Diagram Files (bdf) from Quartus. ...
Today I want to start a blog post series about hardware programming. We start with an introduction to hardware programming with the FPGA-board DE0 Nano from former Altera now Intel. You see a picture of the small board below. It seems you can still order this board, but I have not tested. We will show how to setup the environment, in the first step we will (show how to) download and install quartus on a Debian distribution, and configure the programmer. ...
Introduction Rare earth elements have long been the backbone of high-tech magnets, with metals like neodymium and dysprosium playing pivotal roles in various industries. However, the scarcity and rising demand for these valuable resources have prompted researchers to seek alternative solutions. In an effort to reduce our reliance on rare earth magnets, scientists are exploring innovative materials and alloy combinations. Among the promising contenders is cerium, an abundant and accessible rare earth element, showing potential to replace or augment neodymium magnets. ...
Introduction Rare earth elements, often shrouded in mystery, play a crucial role in our modern world. From smartphones to electric vehicles, renewable energy technologies, and even defense systems, these elements are the unsung heroes that make our daily lives more sustainable, efficient, and connected. In this article, we’ll delve into the fascinating world of rare earth elements, with a focus on the versatile element, neodymium. The Rare Earth Elements: An Overview Rare earth elements (REEs) are a group of seventeen chemical elements that occupy the lanthanide series of the periodic table, along with scandium and yttrium. ...
Today I want to speak about op-amps. These wonderful, but mysterious components, we have heavely often appearing in circuit schematica of analog or analog / digital hybrid circuits. We want to demistify these components. There are two basic thumb rules when handling ideal op-amp circuit. (Real-world op-amp circuits are a bit more complicated, but we will discuss this later). 1. The first thumb rule is that Vout is essentially the difference of the voltage values at the both inputs, multiplied with an arbitrary but high amplification factor A. ...
