A month ago, ElectronicLab modified his office chair with an electric car jack, giving it motorized height adjustment. That worked well, but required that he push buttons to raise or lower the seat. Pushing those buttons is a hassle when one’s hands are full, so ElectronicLab went back to the workbench to add voice control […]
There is something inherently intriguing about submarines that doesn’t seem to apply to other vehicles. Maybe that reflects our natural fears and phobias, or maybe it is a result of our curiosity about the mysterious depths. Maybe it is simply that most of us will never get the chance to ride in a submarine. But […]
Many people around the world live in cities designed for cars, with bicycle use being a distant afterthought. That makes cycling dangerous and lights can do a lot to make riding safer. That’s why Giovanni Aggiustatutto created this DIY system, which includes headlights, a taillight, turn signals, and even an integrated odometer/speedometer. Aggiustatutto wanted this […]
Almost all human-robot interaction (HRI) approaches today rely on three senses: hearing, sight, and touch. Your robot vacuum might beep at you, or play recorded or synthesized speech. An LED on its enclosure might blink to red to signify a problem. And cutting-edge humanoid robots may even shake your hand. But what about the other […]
Good documentation is extremely useful when conceiving, building, or sharing electronic circuit designs, but traditional schematics and technical drawings are difficult for non-professionals to interpret and create. Makers can benefit from intuitive illustrations that look good enough to share. Circuit Canvas, developed by Oyvind Nydal Dahl, makes it easy to quickly create beautiful and useful […]
Total solar eclipses are rare — at least from the perspective of any specific point on the planet. A total eclipse will occur somewhere on Earth once every 18 months or so, but that is more likely to track across the middle of the Pacific Ocean than wherever you happen to be. That made Bernd Kraus feel […]
Dedicated pizza ovens are all the rage right now, as they provide a better-distributed and higher heat that many find more preferable than a conventional kitchen oven. But even a nice gas-powered pizza oven like the Ooni Koda 12 will have some hot spots and cold spots. To get an even bake every time, Yvo […]
An actually level workbench is critical for many different jobs, such as pouring resin or calibrating sensors. But it is difficult enough to level a stationary workbench and that becomes a nightmare for a workbench that needs to roll around a shop on casters, as shop floors definitely aren’t level. That’s why Firth Fabrications crafted this self-leveling […]
It might surprise our urban-dwelling readers, but wells are still very common in rural areas where it is difficult or prohibitively expensive to run utilities. The CDC reports that more than 15 million households rely on groundwater and wells — and that’s just in the United States. But few people haul up old wooden buckets […]
Nixie tubes have been the go-to option for makers looking for retro display aesthetics for many years, because their distinct orange glow carries a lot of vintage appeal. But VFD (vacuum fluorescent display) tubes have been gaining in popularity recently and have different — though similar — appeal. Oskar took advantage of IV-12 VFD tubes […]
