Reddit user “jeff122885” has come up with a fairly simple yet clever coin-operated ticketing system for his Wi-Fi network. The setup consists of a Ch-926 multi-coin acceptor, a MikroTik Groove, and an Arduino Uno with a microSD card module. The unique password for the hotspot is stored in the SD card and read by the Arduino. Once the coins are deposited, […]
Inspired by the one seen in Honey, I Shrunk the Kids, Blake Hodgson has built a remote-controlled lawn mower of his own dubbed ”Lawn Da Vinci.” The robotic machine’s frame is made from angle iron and steel, while its wheels and motors were taken from a mobility scooter. Power is supplied by a pair of 12V car batteries wired in series, and it’s driven across the […]
Let’s face it, there’s something magical about split flap displays. Common throughout older airports and train stations, the electromechanical devices are used to show changeable alphanumeric text (e.g. arrival and departures), fixed graphics, or in Jonathan Odom’s case, Internet slang. With three-letter abbreviations like BRB, LOL, OMG and SMH commonplace in today’s smartphone and online conversations, the Maker decided to bring text and […]
For our throwback project of the week, we stumbled upon a YouTube video that dates all the way back to 2012. And while the viral clip itself (which has over 1.4M views) may be a few years old, the problem it solves is timeless. Unfortunately, you don’t get to choose your neighbors; however, what can choose is how […]
Anyone who has ever watched Ghostbusters is surely familiar with the iconic proton pack–a handheld wand connected to a backpack-sized particle accelerator used for capturing ghosts. With a remake of the ‘80s flick about to hit theaters, what better time for a DIY prop equipped with full-featured user control and Hollywood-like effects? That’s exactly what John Finocchiaro has done using a […]
Designed by Montreal studio Daily tous les jours, Mesa Musical Shadows is a public installation that turns the sidewalk of Arizona’s Mesa Arts Center into a super-sized dance pad which reacts to the shadows of passersby with the sounds of singing. Shadows cast on different tiles trigger different voices, all while singing in harmony. Length of shadow is dependent upon the season, the time of […]
Mike, CEO of the Useless Duck Company, continues to make us laugh with his hilarious Arduino innovations. Despite all the comical projects, which range from a fedora that tips itself to an automated toilet paper-dispensing machine, he may be onto something with one of his more recent contraptions. If you don’t want Google Chrome to save a record of what […]
Taking great pictures means making them more vibrant enhancing saturation and contrast. Ynformatic has published some tips to help you do that by creating a DIY device to control a polarizer using an Arduino Pro Mini, an iPhone, and a screen from an auto-darkening welder’s mask. A phototransistor located facing the iPhone’s flashlight LED is connected to both an external […]
Have you ever wished your Arduino project could play tunes, or even just note-based sound effects? Connor Nishijima has, and that’s why over the last three years he has been hard at work developing Miduino—a free web service that enables Makers to automatically convert their MIDI music into ready-made sketches. Unlike any built-in Arduino noisemaking functions such as tone(), Miduino’s output is polyphonic–meaning you […]
When it comes to telling time, Makers like to go beyond simply reading moving hands or looking at a digital display. In Imgur user Grahamvinyl’s case, that’s a slick word clock comprised of a walnut veneer, clear epoxy, LEDs, letters, and Arduino. Grahamvinyl cut the clock from the back of an acoustic guitar and sides, and then strung together individually addressable RGB strips. A […]
