[ad_1] For decades now, we’ve been able to quickly and reliably interface musical instruments to computers. These tools have generally made making and recording music much easier, but they’ve also opened up a number of other out-of-the-box ideas we might not otherwise see or even think about. For example, [Joren] recently built a human interface […]

[ad_1] You know how the saying goes — they don’t make them like this anymore. It’s arguably true of pretty much any electronic device given the way technology changes over time, though whether or not it’s objectively a bad thing is going to vary from case to case. As a practical example, take a look […]

[ad_1] What’s the simplest audio frequency oscillator you can imagine? There’s the 555, of course, and we can think of a few designs using just two transistors or even a few with just one. But how about an oscillator with no active components? Now there’s a neat trick. Replicating [Stelian]’s “simplest audio oscillator on the […]

In the recent DDR5 update by JEDEC – as reported by Anandtech – we see not only a big speed increase from the […]

[ad_1] DIY shifter knob gets a beautiful integrated LED gear indicator Arduino Team — April 23rd, 2024 We recently covered Vaclav Krejci’s stick shift project, in which he designed a board that surrounds the shift lever and uses Hall effect sensors to detect its position. It then displayed the current gear on a small OLED […]

[ad_1] This week Jonathan Bennett and Aaron Newcomb chat with Isaac Connor about Zoneminder! That’s the project that’s working to store and deliver all the bits from security cameras — but the CCTV world has changed a lot since Zoneminder first started, over 20 years ago. The project is working hard to keep up, with […]

[ad_1] Creating a low-cost EV charging station with Arduino Arduino Team — April 23rd, 2024 The high cost of EV (electric vehicle) chargers may lead you to believe that they’re complex systems. But with the exception of Tesla’s Supercharger, that isn’t true. They’re actually quite simple — basically just glorified switches. All of the nitty […]

[ad_1] Who doesn’t want to use a programming language that is designed to be reliable, straightforward to learn and also happens to be certified for everything from avionics to rockets and ICBMs? Despite Ada’s strong roots and impressive legacy, it has the reputation among the average hobbyist of being ‘complicated’ and ‘obscure’, yet this couldn’t […]

[ad_1] The outgoing MK27 drone used by Amazon today for deliveries. (Credit: Amazon) When Amazon started its Prime Air drone delivery service in 2022, it had picked College Station (Texas) and Lockeford (California) as its the first areas where the service would be offered. Two years later, Amazon has now announced that it will be […]

[ad_1] We’re not certain whether [Paul Gould]’s kid’s prosthetic elbow joint is intended for use by a real kid or is part of a robotics project — but it caught our eye for the way it packs the guts of a beefy-looking motorized joint into such a small space. At its heart is a cycloidal […]
