Mini WALL-E robot delivers gifts
Reading Time: 2 minutesWhile brainstorming gift ideas, Professor Boots settled upon creating a tiny present-delivering robot that could move around on its own power. Because WALL-E’s design already has a built-in compartment and is quite memorable, it became the jumping off point for the project. The entire robot is 3D-printed from a combination of rigid PLA for the…

Can automation help save water?
Reading Time: 4 minutesWhat’s the most important substance in the world? After the air we breathe, the answer is almost certainly water. We need it to live, we can’t go more than a few days without it, and it makes up about 60% of our bodies. All this just makes it even more worrying that…

Building an experimental magnetic loop antenna with a stepper motor and an Arduino
Reading Time: 2 minutesHam radio allows for the broadcast and reception of non-commercial radio signals across vast distances with relatively inexpensive equipment. As the name implies, ham radio relies on antennas to function, and most designs can take up large amounts of space. An alternative antenna is the magnetic loop design which has a tall…

Is it too loud? This Arduino device will do the shushing for you
Reading Time: 2 minutesWhether it is a library, conference room, school classroom, or some other public space, we all require peace and quiet to work sometimes, but achieving it can be a challenge. After wondering if loudmouths could be automatically asked to be silent via some kind of sensor-driven system, Bas op ten Berg, the founder…

Easily create your own robotic camera operator
Reading Time: 2 minutesIf you do any kind of video content creation and you still rely entirely on static shots, then you’re missing out on an opportunity to generate visual interest that draws viewers in. Dynamic shots can do a lot to increase the production value of your videos, but most people can’t afford to…

This machine uses cornstarch to fashion biodegradable pottery
Reading Time: 2 minutesThe art of making pottery has existed for tens of thousands of years, and the materials used have stayed relatively similar as nearly all items were made from clay which was left to harden either from the sun or via a kiln. But for those who wish to do only a little…

A very nimble DIY hexapod robot
Reading Time: 2 minutesWhile robots can get around on two legs (or even none), it is difficult to get a smooth and efficient gait. Moving up to four legs improves the situation a bit, but each of those legs will still need multiple joints and careful balance for the robot to move in a stable…

The weird and wonderful history of chess-playing robots
Reading Time: 4 minutesWho said robots had to be all work and no play? For many years, people have been designing and building robots not just to help with chores, but to help us win games. Possibly the most famous examples of this are the robots that play chess. In this article, we’ll take a…

Celebrate good grades with this Arduino-powered robot
Reading Time: 2 minutesFor some students, getting decent grades or even finding the motivation to attempt to do schoolwork is a challenge, and this is often met with incentives such as money, praise, or simply avoiding embarrassment. Adam Soileau of element14 Presents had the idea to build a robot, which is an incentive unto itself by…

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…

Making jackets smarter by letting them smell
Reading Time: 2 minutesFew things are worse than going to exercise, coming back home, and then realizing that you have been nose blind the entire time to your own odor. In order to detect the potential stench before anyone else does, Luke Berndt and his daughter, Elena, teamed up to create the Smelling Fresh, Feeling Fresh!…

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…

A DIY scissor lift for home theater projectors
Reading Time: 2 minutesWhile their popularity seems to be waning as LCD and OLED TVs grow in size and shrink in price, projectors can still be a good choice for home theaters. They can give you a screen bigger than any TV on the consumer market and at a lower price than large TVs. But…

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…
