Reading Time: 4 minutesHelping hands Handy holders Due to various reasons, humans have two hands. Sometimes less. Balancing wires and solder and a (very hot) soldering iron, or holding a small piece steady painting, can be tricky even for the most dextrous. With movable clamps and a magnifying glass, helping hands make it easier for…

Reading Time: 2 minutesIn The MagPi issue 103 we addressed one of the burning issues of the day: how do I let my family know I’m on a Zoom call? We invented a ‘digital do-not-disturb sign’ that can be remotely controlled by some buttons or an event detected by Home Assistant. Display any message you…

Reading Time: 2 minutesInstall smart lighting Most HA projects start with lighting. Being able to switch lights on throughout the house, wherever you are, or have them react to different sensors or events is a great way to get started in this field. There are a lot of options and the prices have plummeted. Check…

Reading Time: 2 minutesThere are other ways to relay the information, though, such as how Sukriti has made use of touch: “This open-source solution uses a Raspberry Pi Zero W and a mobile phone to relay turn-by-turn instructions with haptic feedback, more commonly known as vibrations, over an SSH connection with the mobile device.” A…

Reading Time: 3 minutesFor Andrew DeGonge, the latter question has a clear cut answer: crusts are to be chopped. Indeed, he’s so determined that the sides of bread are banished, he’s used his loaf and created an automatic guillotine-like device to do the hard work for him. “Crust in general isn’t my main problem. Cheap…

Reading Time: 3 minutesTo use the Explorer Base, your Pico will need to have male pin headers soldered, facing downwards – if you don’t fancy doing this yourself, it’s possible to buy Pico boards with pre-soldered pins. It’s then just a case of mounting your Pico in the dual female headers; a helpful ‘landing area’…

Reading Time: 3 minutesBy rotating a strip of LEDs at high speed and syncing their blinking patterns, it’s possible to create the illusion of a still or moving image. This is just what Japan-based family team of makers HomeMadeGarbage have done for their POV Display, even spinning a Raspberry Pi Pico around with the LED…

Reading Time: 3 minutesTo do this, Chinthaka has been leading a team in using a standard radio-controlled quadrocopter drone fitted with a Raspberry Pi 3B+  and a Camera Module. They’ve worked on an automatic landing system, allowing the drone to be brought down to the ground without mishap. “Automatic landing is a kind of automatic…
