Hackers love a good clock build, but its longer term cousin, the calendar, is more seldom seen in the wild. Regardless, they can be just as useful and elegant a project, as this cryptic design from [Wolfspaw] demonstrates. The project consists of a series of rotating wheels, displaying a series of arcane symbols. When the markings […]

A research team at Imperial College London have created a new aerial sensor deployment system which uses a drone capable of firing Sense darts into tree trunks for data collection from hard to reach locations. The drone firing mechanism uses a compressed spring together with a shape-memory alloy (SMA) trigger to fire the sensor pods

What is it about useless machines that makes them so attractive to build? After all, they’re meant to be low-key enraging. At this point, the name of the game is more about giving that faceless enemy inside the machine a personality more than anything else. How about making it more of a bully with laughter

User [mircemk] presents his “MiliOhm Meter” project which you can build with an Arduino, a handful of common parts from your lab, and a cigar box. It doesn’t get much simpler than this, folks. While this is something you won’t be getting calibrated with NIST traceability, it looks like a fun and quick project that’s more than

A mechanical and manufacturing engineer by day, [Tyler Collins] taught himself electronics and firmware development in his spare time and created an open source Lego controller called Evlōno One. It is based on the STM32 and Arduino ecosystems, and compatible with a impressive variety of existing Lego controllers, sensors and actuators. [Tyler] encountered Lego Mindstorms while helping in

Today it is pretty easy to build a robot with an onboard camera and have fun manually driving through that first-person view. But builders with dreams of autonomy quickly learn there is a lot of work between camera installation and autonomously executing a “go to chair” command. Fortunately we can draw upon work such as View

We suppose it’s a bit early to call it just yet, but we definitely have a solid contender for Father of the Year. [DIY_Maxwell] made a light-up hockey game for his young son that looks like fun for all ages. Whenever the puck is hit with the accompanying DIY hockey stick (or anything else), it lights up

It seems like every year, it gets a bit easier to build your own CNC. From the Enhanced Machine Controller (EMC) project of the early 1990s to Arduinos running Grbl in the late 2000s, the open source community has moved ahead in leaps and bounds. Grbl is at its core firmware that interprets G-code and

The official Arduino development team has this week announced a new partnership with Lauterbach to provide all Portenta H7 customers with the TRACE32 debugger for free. The Lauterbach TRACE32 debugger has been at the forefront of debug technology for more than four decades, and it is this wealth of experience and expertise that Lauterbach will
Portenta H7 advanced debugger now available for free Continue Reading
These days, a classic Jack O’ Lantern just doesn’t cut the mustard. Kids are expecting to be scared by high-quality animatronics at a minimum. This haunting work by [Zero To Infinity] might just do the trick. A real pumpkin is pressed into service in this build, with the usual threatening grin and candlelit interior. However, where
