Solar upgrades the Nebulophone synthesizer to enhance playability 

Reading Time: 2 minutesWoodwinds and brass are so 19th century. We’re living in the future and now it is synthesizers all the way down. There are many to choose from and the Bleep Labs Nebulophone is a neat example that was sold from 2012 to 2016, with the design files now available on GitHub for DIYers. Marcus Dunn […]

Using a racing sim rig with a real RC car

Reading Time: 2 minutesMost of us will never get a chance to drive a Ferrari F50 around the Nürburgring in real life, but we can all do so in a racing sim. To get the most out of that experience, many people build serious and elaborate racing sim rigs. What if one could use their racing sim rig […]

A homemade launchpad for compressed air-powered rockets

Reading Time: 2 minutesA conventional model rocket engine is simple combustible solid fuel (black powder or more advanced composites) molded into a cylinder that uses expanding gas to produce thrust. Though it is minimal, there is some danger there. An alternative is compressed gas, which will also expand to produce thrust — just without the explosive chemical reaction. […]

This student made his own odds with a DIY slot machine

Reading Time: 2 minutesToday’s digital slot machines are anything but “fair,” in the way that most of us understand that word. There is tight regulation in most places, but the machines can still adjust their odds of payout in order to maintain a specific profit margin. If the machine thinks it has paid out too many wins recently, […]

Forgot your safe combination? This Arduino-controlled autodialer can crack it for you

Reading Time: 2 minutesSafes are designed specifically to be impenetrable — that’s kind of the whole point. That’s great when you need to protect something, but it is a real problem when you forget the combination to your safe or when a safe’s combination becomes lost to history. In such situations, Charles McNall’s safe-cracking autodialer device can help. […]

Quickly digitize your Magic deck with this 3D-printable scanning rig

Reading Time: 2 minutesWe call them “deck builders” for a reason: because players end up with huge piles of trading cards. They can get difficult to manage, which is why the ManaBox app exists for Magic: The Gathering. It lets collectors scan and log their decks, which is handy for everything from finding market values to optimizing deck builds. […]

SeaPerch II introduces students to underwater ROV exploration

Reading Time: 2 minutesWhile professionals around the world take advantage of Arduino products and the extensive ecosystem, the core Arduino philosophy is to simplify complex technology. A bare microcontroller is intimidating to the uninitiated, but an Arduino development board is friendly and approachable. MIT’s Sea Grant is harnessing that in their new SeaPerch II underwater ROV (remotely operated […]

This DIY experimental reactor harnesses the Birkeland-Eyde process

Reading Time: 2 minutesNitrogen is critical for farming at scale and without some form of nitrogen to enrich the soil, we couldn’t grow staple crops efficiently enough to feed our large global population. Serious science goes into the production of fertilizers and the Birkeland-Eyde process was one early example. It uses electrical arcs to turn nitrogen in the […]

Arduino Days 2025 is almost here!

Join us for two days of live-streamed content on March 21st-22nd, featuring inspiring talks, major product announcements, and community showcases from makers, educators, and industry leaders worldwide. Big announcements and […]

A DIY sous vide cooker for making the perfect steak

Reading Time: 2 minutesSous vide (which means “under vacuum” in French) is a cooking technique in which food is sealed in a plastic bag (or another container) and immersed in warm water for a long period of time. It is great for meat, like steak, because it ensures the food is an even temperature throughout. For a steak, […]

This Arduino device helps ‘split the G’ on a pint of Guinness

Reading Time: 2 minutesGuinness is one of those beers (specifically, a stout) that people take seriously and the Guinness brand has taken full advantage of that in their marketing. They even sell a glass designed specifically for enjoying their flagship creation, which has led to a trend that the company surely appreciates: “splitting the G.” But that’s difficult […]

A lightweight file server running entirely on an Arduino Nano ESP32

Reading Time: 2 minutesHome file servers can be very useful for people who work across multiple devices and want easy access to their documents. And there are a lot of DIY build guides out there. But most of them are full-fledged NAS (network-attached storage) devices and they tend to rely on single-board computers. Those take a long time […]

This vending machine draws generative art for just a euro

Reading Time: 2 minutesIf you hear the term “generative art” today, you probably subconsciously add “AI” to the beginning without even thinking about it. But generative art techniques existed long before modern AI came along — they even predate digital computing altogether. Despite that long history, generative art remains interesting as consumers attempt to identify patterns in the […]

This three-fingered robot hand makes use of serial bus servos

Reading Time: 2 minutesA small startup called K-Scale Labs is in the process of developing an affordable, open-source humanoid robot and Mike Rigsby wanted to build a compatible hand. This three-fingered robot hand is the result, and it makes use of serial bus servos from Waveshare. Most Arduino users are familiar with full-duplex serial communication, which requires two […]

DIY micro lab analyzes ammonia levels in blood and urine

Reading Time: 2 minutesCirrhosis of the liver is an extremely serious condition that requires extensive medical monitoring and often intervention. Progression of the condition can be fatal, so even if caught early it must be monitored closely. But, like most things in medicine, that gets expensive. That’s why Marb built his own DIY “micro lab” to analyze ammonia […]

The 2024 Arduino Open Source Report is here!

A year of growth and […]

This mod simplifies single-point threading on mini lathes

Reading Time: 2 minutes“Single-point threading” on a lathe is the process of cutting threads, such as for a bolt, into the material through turning. The spindle/workpiece spin and the carriage moves linearly at a precise amount per turn of the spindle. That linear movement is the thread pitch. But this process usually requires several passes to reach the […]
