Send text messages over ham radio with the HamMessenger

Ham radio, or amateur radio, is a hobby enjoyed by millions of enthusiasts around the world. The FCC in the US and similar organizations in other countries provide amateur radio licenses that allow hobbyists to communicate on designated radio bands. Most ham radio operators communicate by voice, but ham radios can transmit other kinds of […]

Meet your new table tennis coach, a tinyML-powered paddle!

Meet your new table tennis coach, a tinyML-powered paddle!

Shortly after the COVID-19 pandemic began, Samuel Alexander and his housemates purchased a ping pong set and began to play — a lot. Becoming quite good at the game, Alexander realized that his style was not consistent with how more professional table tennis players hit the ball, as he simply taught himself without a coach. Because of […]

This Arduino-powered robotic fish swims like the real thing

Biomimicry is often used to take the designs that nature has perfected over a period of millions of years and incorporate them into our own technology. One maker who goes by mcp on YouTube took this idea one step further and created a fish that can swim in the water like the actual creature. By carefully analyzing and studying […]

Using the MKR IoT Carrier board as a game console

Using the MKR IoT Carrier board as a game console

One of the first things many makers try to do when they receive a new piece of cool hardware is write a game for it. This is exactly what Johan Halmén did with his Breakout console that uses the Arduino MKR IoT Carrier board and an MKR1000 to both run and display the game.  Breakout typically involves […]

An Arduino-powered micro quadruped that fits in the palm of your hand

An Arduino-powered micro quadruped that fits in the palm of your hand

Arduino-powered quadruped robots are quite common projects for hobbyists to build once they are a bit more comfortable with embedded systems. One problem with many of the pre-designed quadruped platforms is that they require a lot of time to assemble owing to their large size. This is what inspired Technovation to come up with their own micro […]

Kinetic digital clock takes 7-segment displays to another dimension

Kinetic digital clock takes 7-segment displays to another dimension

Seven-segment displays have been around for ages, and they have a really cool retro aesthetic about them. Over on Instructables, user alstroemeria (known as Jacky Mok in real life) decided to build a different kind of display that utilizes individual servo motors to slide the segments out, thus creating a 3D clock. The main board in this project was […]

This interactive beer pong table is lit, literally

Beer pong and its derivatives are some of the most enjoyed games on college campuses, but they are not all that exciting with just a few cups at either end of a plastic folding table. Meet the Interactive Pong Table, which was created by Instructables user boregan1. It features a fully-custom tabletop gaming experience with a large […]

This light painting machine puts a new spin on the old geometric chuck

Light painting is a fun way to create digital images by using just a few points of light to “draw” across a camera with a long exposure time. This gives the illusion of a virtual streamer being dragged on the canvas and can produce amazing photos. Ted Kinsman wanted to build a light painting machine, which […]

VoiceTurn is a voice-controlled turn signal system for safer bike rides

Whether commuting to work or simply having fun around town, riding a bike can be a great way to get exercise while also enjoying the scenery. However, riding around on the road presents a danger as cars or other cyclists / pedestrians might not be paying attention while you try to turn. That is why Alvaro […]

Watch your music come to life on this single LED strip audio spectrum visualizer

Watch your music come to life on this single LED strip audio spectrum visualizer

While thinking of an interesting project to create, Hackster user marcaubin started to imagine an audio spectrum visualizer, but not a traditional one that has a matrix of LEDs with columns corresponding to certain frequencies. Instead, his device would have just a single vertical NeoPixel strip featuring 29 LEDs in total, with the bottom ones displaying the […]
