Any exercise is a positive thing, but if you’re looking to improve over time, you’ve got to measure your performance. [Nikodem Bartnik] is a runner and is looking to improve his sprinting abilities. Naturally, an Arduino is the perfect companion to help in this quest (YouTube link, embedded below). The Arduino is built into a […]
Over the past few decades of evolution, cars have grown to incorporate a mind-boggling number of electric components. From parking distance sensors, to the convenience of power locks and windows, to in-car entertainment systems rivaling home theaters. Normally this interconnected system’s complexity is hidden between exterior sheet metal and interior plastic trim, but a group […]
In the world of oscilloscopes, as in the rest of the test equipment world, there’s always some trickery afoot. Companies will often offer different models to the market at different price points, in an effort to gain the widest possible customer base while also making the most profit. Cheaper, less capable models are often largely […]
Pluto may no longer be a planet, but it is still a fun software defined radio (SDR) set up from Analog Devices. The inexpensive radio uses a USB connector and looks somewhat like a network connection to your PC. But what if you want to really use it with a network? [SignalsEverywhere] shows you how […]
A good majority of power tools in the average workshop are all about speed. Drills, grinders, and sanders all whizz along at thousands of revolutions per minute. Sometimes though, you need to do things slowly. For that, [bongodrummer]’s big rotary machine build might be just up your alley. The core of the build is an […]
The obsession with over-the-top-hardware conference badges means that we as attendees get to enjoy a stream of weird and wonderful electronic gadgets. But for the folks putting these conferences on, getting a badge designed and manufactured in time for the event can be a stressful and expensive undertaking. To keep things on track, the designs […]
It might not be the kind of thing you’ve given much thought to, but if you’ve ever used a desktop 3D printer, it was almost certainly being controlled by an 8-bit CPU. In fact, the common RAMPS controller is essentially just a motor driver shield for the Arduino Mega. Surely we can do a bit […]
The 1970s, it was a time when cameras needed film, phones had cords, and televisions masqueraded as furniture. A time where hi-fi systems were judged by the volume knob feel, and thanks to YouTube user [nefesh22] we have a behind-the-scenes glimpse of what the era was like from the Sony corporate perspective in this mini […]
Hackaday editors Elliot Williams and Mike Szczys gather round the microphone to spin tales from a week of hacks. All the rage are fax-machine-based malware, a hydrogen fuel cell drone, and bringing color to the monochrome world of the original Super Mario Land. There are at least three really cool LED hacks this week, plus […]
Using a legitimate flamethrower is on the bucket list for a lot of us. Even Elon Musk got into the action with his Not-A-Flamethrower flamethrower. For the rest of us non-billionaires though, we have to come up with clever reasons to build our own like “Halloween is only six months away”. [HandsomeRyan] took this approach […]
