A 3D-printable, Arduino-controlled star tracker great for astrophotography
Reading Time: 2 minutesMost modern digital cameras are perfectly capable of capturing photos of the stars. But many of them have trouble collecting the small amount of light available in a short amount of time, which means that you need to leave the shutter open for 30 seconds or more to get a decent exposure.…

DIY focus stacking device aids in macro photography
Reading Time: 2 minutesIf you’re ever tried to capture some macro photographs (very close-up pictures), you’ve probably noticed that it is difficult to get proper focus. Because the depth-of-field (DoF) for macro lenses is so small, you can only keep a narrow range of distance in focus at any given time — everything else is…

Multi-function device displays PC data and news
Reading Time: 2 minutesWhile the typical computer user doesn’t need to worry about it, those of us who overclock our computers or run them hard like to know how they’re performing. If, for example, you overclock your CPU, then you probably want to keep an eye on its temperature to ensure that it doesn’t exceed…

The Arduino Launch Control System is a model rocket enthusiast’s dream
Reading Time: 2 minutesConventional hobby model rockets get their thrust from disposable motors containing an explosive propellant, like black powder. But unlike the gun powder in a firearm’s cartridge that uses a concussion-activated primer to ignite, model rocket enthusiasts ignite their motors using an electric arc. Simple launch controllers consist of little more than a…

This pen plotter gets nervous when observed
Reading Time: 2 minutesThe whole purpose of machine automation is to eliminate human needs and errors. A CNC machine doesn’t get tired, doesn’t need breaks, and performs a task exactly the same way every time. But what if that weren’t true? What if machines experienced human emotions and let it affect their work like we…

Substituting a flex sensor for an inexpensive light-dependent resistor
Reading Time: 2 minutesIn order to build wearables that react to movement, most people tend to reach for accelerometers, gyroscopes, and flex sensors. But due to their higher cost, one of teacher Gord Payne’s students wanted to create a low-cost alternative that could be easily sourced and integrated into projects. A typical glove with finger movement tracking normally…

This glove translates sign language using an array of sensors
Reading Time: 2 minutesFor people not familiar with American Sign Language (ASL), being able to recognize what certain hand motions and positions mean is a nearly impossible task. To make this process easier, Hackster.io user ayooluwa98 came up with the idea to integrate various motion, resistive, and touch sensors into a single glove that could convert these signals into…

This search and rescue robot creates 3D maps of disaster areas
Reading Time: 2 minutesIf you look at footage from the search and rescue efforts following any disaster, you’ll see that first responders have a very difficult time navigating through rubble to find people in need of emergency care. They also have to take extra precautions, as gas line ruptures and other hazards present dangers they…

This reverse geocache gift box only opens at specific GPS coordinates
Reading Time: 2 minutesGeocaching is a hobby that combines the fun of a scavenger hunt with modern GPS technology. One party will hide a small cache somewhere, then post the general location and the exact GPS coordinates for other parties to find. The goal is to use GPS navigation to find the hidden cache. Often,…

This Arduino Nano-based synthesizer can produce a wide range of intriguing sounds
Reading Time: 2 minutesSynthesizers have existed in their current form for several decades now. In essence, they generate simple waveforms that are then either added or subtracted together and modified through the use of filters, envelopes, and modulators to control pitch, volume, and several other characteristics. Due to their simplicity, many types of components can…

Make your own micro FPV drone racing gate
Reading Time: 2 minutesDrone racing is an increasingly popular hobby, especially as high-performance drones get more and more affordable. Racing drones can reach 200mph and a huge part of the skill set necessary for competition is the pilot’s ability to navigate through gates at high speed. Those gates mark check points on the course, a…

Arduino brings birthday cake to life
Reading Time: 2 minutesA good birthday cake is all about the decoration. Usually that comes in the form of fancy frosting, fondant flourishes, and crazy candles. But what if you got electronics involved? That’s the question Natasha Dzurny answered when she used an Arduino to bring a birthday cake to life with epic LED lighting.…

This project facilitates augmented reality Minecraft gaming
Reading Time: 2 minutesAugmented reality (AR) is distinct from virtual reality (VR) in that it brings the real world into virtual gameplay. The most famous example of AR is Pokémon Go, which lets players find the pocket monsters throughout their own physical region. Minecraft is the best-selling video game of all time, but lacks any official AR gameplay.…

Nifty cam-following plotter can draw many shapes
Reading Time: 2 minutesBefore CNC (computer numerical control) came along, automated machines utilized mechanisms like cams and tapers to act as guides. Those are physical components with precise contours meant to guide the tool, like an artist tracing lines with a pantograph. Such mechanisms are uncommon today, as CNC is far more versatile and much…

This train of trash bins moves to the curb with the press of a button
Reading Time: 2 minutesOnce a week, millions of people set out their trash cans next to the curb for collection the following day, which many consider to be extremely annoying or laborious. So rather than manually dragging out the garbage and recycling bins, the YouTuber known as Max Maker decided to build a system that…
