Magnets (especially those ball magnets!) are endlessly fascinating, aren’t they? It’s almost dangerous to combine them with LEDs, because how are you supposed to get anything done with something like [andrei.erdei]’s Arduino Magnetic Board beckoning from beyond your keyboard? This tons-of-fun board uses ball magnets to light up RGB LEDs as they roll around on the sexy […]

Musicians, makers and Arduino enthusiasts may be interested in a new project created by Max Danilin, showing a DIY automatic barrel piano, powered by an Arduino micro-controller and capable of outputing MIDI signals. A sheet is pulled under an array of 40 optocouplers using a hand crank and converted to sound using a MKR Zero

Cablecams are a lot of fun, but they’re not inexpensive, even if you need just something small for your action camera. There are commercial solutions out there, like the Wiral Lite, but they’re pretty expensive for what they are. Perhaps even more so than the camera you’re mounting to it. When Kasper at MAKESOME was asked by his friend

One of the disadvantages of having cheap WiFi-capable boards like those based on the ESP32 is that you have to update them. If you have even a few in every room of your house, it can be a pain to pull them out and connect them to a cable for programming. Over the air programming

[Ivan] seems to enjoy making 3D printed vehicles with tracks. His latest one uses 50 servo motors to draw patterns in the sand at the beach. You can see it work in the video below. Well, more accurately you can see it not work and then work as the first iteration didn’t go exactly as planned. An

Where won’t they put a TV these days? We’ve even seen one creeping behind semi-transparent mirror film in the ladies’ room of a sports bar, though that one didn’t last long. Up until that moment, we had never wished so hard for a TV-B-Gone, especially one as small and powerful as this DIY version by [Shane].

Today the official Arduino development team have rolled out a new update to the Arduino CLI, adding some new exciting features in version 0.11.0. New features include Command-line completion, External programmer support and Internationalization and localization support (i18n). “Finally, the autocompletion feature has landed! With this functionality, the program automatically fills in partially typed commands
Arduino CLI receives command-line completion, external programmer support and more Continue Reading
Cheap 433 MHz wireless switches are a tempting way to enter the world of home automation, but without dedicated hardware, they can be less easy to control from a PC. That’s the position [TheStaticTurtle] was in, so the solution was obvious. Build a USB 433 MHz transceiver. At the computer end is a CH340 USB-to-serial chip
433 ON A STICK Continue Reading
All by itself, a calculator based on an Arduino isn’t necessarily very novel. However, [Volos] has a nice board that, of course, looks like a calculator. There are 16 keys and an LED display. But it seems to us the real value would be using this as a base for other projects. As an inexpensive development board,

Whilst swapping out the stereo in his car for a more modern Android based solution, [Aaron] noticed that it only utilised a single CAN differential pair to communicate with the car as opposed to a whole bundle of wires employing analogue signalling. This is no surprise, as modern cars invariably use the CAN bus to
