In this post, we will talk about Retro-LED-Strip-Audio-Visualizer: As a musician and electrical engineering student, I love any project that intersects these two fields. I’ve seen some DIY audio visualizers (here, here, here, and here), but each had missed at least one of the two goals I established for myself: professional build quality and a […]

Most cameras these days offer some kind of built-in WiFI or Bluetooth control that allows you to fire your camera from an app on your smartphone. But not all of them do. The Ricoh GRII is one of those cameras that actually does offer some remote control via an app or USB remote, but sometimes you still want that tactile

Many individuals link the ESP family of microcontrollers with WiFi, as they have become the preferred solution for connecting your project to the internet swiftly and easily. Although WiFi is often highlighted, the ESP32 also includes Bluetooth, which is not utilized by users as frequently. If you want to begin using Bluetooth on the ESP32,then

Most readers of Hackaday will be well aware of the current shortages of semiconductors and especially GPUs. Whether you’re planning to build a state-of-the art gaming PC, a mining rig to convert your kilowatt-hours into cryptocoins, or are simply experimenting with machine-learning AI, you should be prepared to shell out quite a bit more money

“What’s the weather going to be like today?” is a question that’s near-permanently on the mind of those living in places like Britain, where brilliant sunshine can follow thick clouds, only to turn into drizzle an hour later. Nowadays you simply need to glance at your phone to know whether you need to pack an

Plenty of clocks around us are useful for telling us the precise hour, minute, and second of the day. However, few can give us an intuitive sense of how far away we are from the enveloping cloak of night. This 3D printed Earth clock built by [Simon Rob] promises to do just that. The build consists

The UK in the 1980s was ground zero for the microcomputer revolution. Cheap computers based on 8-bit processors flooded the market, teaching a generation to program using built-in BASIC interpreters. Homes had devices like Sinclair’s ZX81 and Spectrum, while schools used Acorn’s BBC Micro. More about Innovation These weren’t like today’s PCs. They were designed

What is part way between a printed circuit board and a rats-nest of point-to-point wiring? We’re not sure, but this is it. [Johan von Konow] has come up with an inspired solution, 3D printing an Arduboy case with channels ready-made for all the wires. The effect with his 3DPCBoy is of a PCB without the PCB,

[Lee Adamson] is no stranger to classic computers. He recently picked up a Heathkit H11A which, as you might remember, is actually a PDP-11 from DEC. Well, technically, it is an LSI-11 but still. Like a proper LSI-11, the computer uses the DEC QBus. Unlike a lot of computers of its day, the H11 didn’t have a
