All about electronics and circuit design

Capacitor distortion

A resistor is a resistor, a coil is a plain ol’ inductance, and a capacitor is a capacitor – or so you thought. Alas, life isn’t quite so trivial… There are non-ideal properties of real components. Capacitors have non-idealities that you should know about when designing electronics circuits. If you are building high frequency circuits

Audio measurement software

Here are links to some useful audio measurement software: https://www.roomeqwizard.com/ Many people rely on the Room EQ Wizard (REW) software. This “donationware” program measures every aspect of room acoustics (e.g., frequency response, reverb decay times, and much more). It also includes a distortion analyzer to measure the distortion of loudspeakers. Coupled with a high-quality sound

60 years of BASIC

Happy birthday to Basic, possibly the most important programming language of all time! The Easy-to-use language that drove Apple, TRS-80, IBM, and Commodore PCs debuted in 1964. The BASIC programming language turns 60 article says: “Sixty years ago, on May 1, 1964, at 4 am in the morning, a quiet revolution in computing began at

USB cable quality

Broken USB cables. This USB-A to USB-C cable from Biltema was cheap, but the quality and robustness could been better. I have several cables that have all broken exactly like this. I don’t remember many other USB cable that would have damaged like this. If they had used decent construction in the USB C connector,

Green code and green IT

Digitalization and software have made our lives easier and made our operations many times more efficient over the past decades. Data centers consume two to three percent of the planet’s total electricity usage now. It has considerable CO2 footprint. Various ICT solutions are responsible for 4–10 percent of annual electricity consumption and 3–5 percent of

Interesting maps

Openstreetmap OpenStreetMap is the free wiki world map. https://www.openstreetmap.org/ Why use OpenStreetMap instead of Google Maps? Customization: OSM is highly customizable, allowing developers to tailor the map to their specific needs, while Google Maps and Apple Maps have more limited customization options. Data ownership: OSM is built and maintained by a community of contributors, which

Plastic bottle recycling

Plastic recycling is the process of recovering waste plastic and reprocessing it into new products. It plays a crucial role in reducing the environmental impact of plastic waste by diverting it from landfills and incineration, conserving resources, and minimizing pollution. Plastic recycling is challenge. Plastic recycling has been seen so complex that lots of materials
