Depends what you want. I’d go with a microcontroller for starts so you can change it programmatically. I’d bet someone has done it with an Arduino or Pi. Here are some links to interesting looking projects. Those circuits operate mostly at safe low voltages and control low power LEDs. The same ideas can be used →
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 →
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 →
Audio Engineer Shitposting on Facebook has a competition: Turn any famous song lyrics into a bad mixing advice. The original examples were those: Whoa, we’re half way there Whoa oh, don’t eq your snare She was a streamer girl he was a pirate boy? It gave me inspiration to make some of my own mixing →
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 →
Why??? They are so cheap these days compared to what they used to cost, why would you even bother to build your own fixtures? You will have more invested in parts and time then just buying them outright. I did build some disco lights in 1990′s. Nowadays you can buy many disco lights more cheaply →
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, →
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 →
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 →
This posting is here to collect cyber security news in April 2024. I post links to security vulnerability news to comments of this article. You are also free to post related links to comments. →
