A delightful Chandrayaan-3 rocket launch model

Reading Time: 2 minutesIt may not get as much attention as NASA, Roscosmos, or even CNSA (China National Space Administration), but India’s space program has achieved some impressive goals. Just last year, in August of 2023, ISRO (Indian Space Research Organisation) completed their first soft landing on a celestial object with the Chandrayaan-3’s moon landing. That understandably inspired […]

Can I build my own robot with Arduino?

Reading Time: 5 minutesWhen you think of automation, what’s the first image that comes to mind? For many of us, it’s a robot. From the blocky, square-headed characters of sci-fi comic fame to household more complex creations like the Replicants of Blade Runner — robots have captured our collective imagination for a long time. It’s no surprise, then, […]

An easy way to add a gear indicator for your stick shift

Reading Time: 2 minutesThe objective benefits may be almost nonexistent today, but there is still something satisfying about rowing through the gears in a car with a manual transmission. If that car was made in the past couple of decades, there is a good chance that it has an indicator on the dash to tell you what gear […]

High school student builds his dream racing wheel

Reading Time: 2 minutesRacing “video games” can be incredibly realistic these days, with every facet of the car’s physics and their interaction with the asphalt programmed in. Those racing sims could provide a completely immersive experience — if the player wasn’t sitting on a motionless couch using a controller that doesn’t resemble a car’s steering wheel in the […]

DIY “Staccato” controller drives Tesla coils

Reading Time: 2 minutesThe Tesla coil, patented by legendary inventor Nikola Tesla in 1891, is a kind of resonant transformer circuit capable of producing sparks of high-voltage alternating-current electricity. They don’t have many practical uses today beyond novelty, but they were commonly used in spark-gap radio transmitters in the early 20th century. The sparks generated by a Tesla coil […]

Autochef-9000 can cook an entire breakfast automatically

Reading Time: 2 minutesFans off Wallace and Gromit will all remember two things about the franchise: the sort of creepy — but mostly delightful — stop-motion animation and Wallace’s Rube Goldberg-esque inventions. YouTuber Gregulations was inspired by Wallace’s Autochef breakfast-cooking contraption and decided to build his own robot to prepare morning meals. Gregulations wanted his Autochef-9000 to churn out traditional […]

This new game engine runs Manic Miner on an Arduino UNO

Reading Time: 2 minutesFor owners of Sinclair ZX Spectrum computers in the ‘80s, few games were more desirable than Matthew Smith’s Manic Miner. It is very much a classic and has official and unofficial ports available for just about every console and computer released since. There was even a port made for Microsoft’s Zune MP3 player. And now […]

This animatronic CatNap is predictably creepy

Reading Time: 2 minutesPoppy Playtime is an interesting horror video game — or rather, an episodic series of games — that puts players into the eerie toy factory of fictional company Playtime Co., where they find that the company’s characters are alive and quite aggressive. A big part of the game’s appeal is the creepy character design, with the […]

Getting more realistic camera movements in VR with an Arduino

Reading Time: 2 minutesIn virtual reality, anything is possible, yet being able to accurately model things from the real-world in a digital space remains a huge challenge due to the lack of weight/feedback that would otherwise be present in physical objects. Inspired by working with digital cameras and the inherit imperfection they bring to their videos, Bas van […]

Build yourself this simple app-controlled robot dog

Reading Time: 2 minutesIf you have an interest in robotics, it can be really difficult to know where to start. There are so many designs and kits out there that it becomes overwhelming. But it is best to start with the basics and then expand from there after you learn the ropes. One way to do that is […]

A single stepper motor drives this mechanical seven-segment display clock

Reading Time: 2 minutesIt is amazing how much technological progress humanity has achieved over the past few centuries. But while our capability with electronics has shot ahead, it seems that we’ve almost regressed when it comes to mechanical and electromechanical design. Watches and clocks are great examples of this, as pre-digital craftsmen were capable of astonishing feats that […]

This kinetic light installation illuminates the Finnish snow

Reading Time: 2 minutesIf you’re ever driving through rural Finland about an hour south of Jyväskylä, you might come across the Haihatus art center. That includes KITA, “the house of kinetic arts.” You’ll recognize it right away by its bold swaths of vibrant paint. And if you come by at night, you’ll see the snow illuminated in dancing […]

Controlling 3.6kW of solar EV charging with an Arduino GIGA R1 WiFi

Reading Time: 2 minutesThe EV (electric vehicle) versus ICE (internal combustion engine) debate is more complicated that it may seem, but one fact is quite simple: it is much easier to generate electricity at home than it is to refine fossil fuels. This means that it is possible power a vehicle for free after the initial investment. But […]

Motion control interface facilitates robot operation for those with paralysis

Reading Time: 2 minutesHenry Evans suffered a brain-stem stroke 20 years ago that left him paralyzed with quadriplegia. He can move his head, but other than a small amount of movement in his left thumb, he can’t control the rest of his body. To help Evans live a more independent life, researchers from Carnegie Mellon University’s School of […]

Opta: Enhanced cybersecurity after HWG Sababa’s testing

The Hardware-Oriented Microprocessor Simulator illustrates the inner workings of microcontrollers

Reading Time: 2 minutesDo you really understand what is happening within the mysterious black packaging of a microcontroller or microprocessor? Most people don’t — we just learn how to use them. That’s because they’re wildly complex circuits combining many different subsystems that are all abstracted away from the view of the user. To help students better understand these integrated circuits […]
