OpnBeat is a DIY lo-fi sampler that anyone can learn to use
Reading Time: 2 minutesMost electronic music is created through either sampling or synthesizing sounds. A synthesizer generates sounds on demand according to the input parameters (like frequency and amplitude), while a sampler plays prerecorded sound clips — often with overlaid effects to alter the sound. Both are very versatile, but that means that they can…

Cave exploration made safer with the Nicla Sense ME-powered Sajac Project
Reading Time: 2 minutesThe art of cave exploration, or spelunking, can get its practitioners far closer to nature and the land we inhabit, but it also comes with a host of potential dangers. Some include extreme environmental conditions, lack of oxygen/toxic gases, and simply having their path closed off due to rock falls. Seeing these…

Portable bioprinter could help fight cancer
Reading Time: 2 minutesTo test experimental cancer-fighting therapies, researchers need cancerous tumors to treat. While lab animals, like mice, can provide those tumors, they come with many downsides. From ethical concerns to practical reasons, such as tumor isolation and repeatability, “natural” tumors come at a cost. Artificial tumors, made using real cells, can solve these…

Micro robot arm controls macro robot arm
Reading Time: 2 minutesBuilding a capable robot is only half of the battle. To take advantage of that robot, you’ll need a good way to control it. When it makes sense, you can pre-program movements. But when you want to control a robot in real time, you need suitable controller. Conventional joysticks and gamepads don’t…

Old RC transmitter becomes new MIDI controller
Reading Time: 2 minutesIf you’re going to produce electronic music on a PC, you need some sort of input tool. That can be your keyboard and mouse, but most producers prefer to use a dedicated MIDI (Musical Instrument Digital Interface) controller. That will provide a more intuitive and efficient experience. Instead of buying something new, HYPRREAL turned…

Build your own virtual camera operation hand wheels
Reading Time: 2 minutesMany tools, such as milling machines, use hand wheels for operation, because they allow for smooth and precise movement. For the same reason, some professional camera rigs also use hand wheels for panning and other moves. To mimic that in a simulated environment, you can build your own virtual camera operation hand…

A history of robotic pets (and how to make your own)
Reading Time: 4 minutesHumans have domesticated animals since the dawn of time. Dogs (our oldest furry friends) were owned by humans as far back as 30,000 years ago, and since then we’ve formed bonds with all kinds of different creatures. It was only in the last century, though, that we started to actually build our…

Automated winding machine features a self-reversing screw
Reading Time: 2 minutesThe world of mechanical engineering is full of interesting and ingenious mechanisms. The Geneva drive, for example, translates rotary motion into intermittent ticking — perfect for a wristwatch or clock. With a clever mechanism, one can reduce the need for complicated control electronics. That was the case with the self-reversing screw that…

This internet uptime indicator reduces frustration
Reading Time: 2 minutesBandwidth may have increased dramatically over the past couple of decades, but internet connections are often still quite unreliable. For people with unreliable connections, it becomes a chore to check a browser over and over again to find out when the internet is back up. To avoid that hassle, Emily Velasco built…

An experimental low-cost ultrasonic drone positioning system
Reading Time: 2 minutesDrone shows have become a big trend over the past few years, with some shows containing thousands of individual drones. Those shows are wildly expensive, because the drones can easily cost a couple thousand dollars each. A big part of the reason for their high cost is their onboard positioning systems, which…

This remote sensor system determines if water is good for drinking
Reading Time: 2 minutesThe public often hears from various media outlets and documentaries that many regions in the world lack consistent access to quality drinking water. But what does exactly does that mean? It is more than water that is clear and free of parasites. Distilled water, for example, isn’t recommended as drinking water because…

James Bruton’s robot centipede of many legs
Reading Time: 2 minutesStrangely, no centipede has exactly 100 legs. They can have either more or fewer than 100 legs, but not exactly 100 because they always have an odd number of pairs. Sadly, that means that James Bruton’s centipede robot is anatomically incorrect — though cool nonetheless. Bruton built this centipede robot as a scaled-down prototype,…
