Collaborate Disseminate
If there’s one thing that continues to impress us about the Hackaday community as the years roll by, it’s the willingness to share what we’ve learned with each other. Not …read more Continue reading Air-Assist Analysis Reveals Most Effective — and Quietest — Methods
For some of us the smell of rosin soldering flux vaporizing from the tip of an iron as a project takes shape is as evocative as the scent of a rose on a summer’s day. We’ve certainly breathed enough of it over the years, as it invariably goes from the …read more

A new study is offering the most comprehensive real-world demonstration of how volatile organic compounds (VOCs) can spread throughout indoor environments from cigarette smokers’ clothing and bodies. Often referred to as third-hand smoke, the research … Continue reading New Yale study rekindles debate over dangers of third-hand smoke
While we’re certainly not denying that smoke detectors are useful, there’s a certain kind of tragedy to the fact that most of them will never realize their true purpose of detecting smoke, and alerting us to a dangerous fire. On the other hand, [Ben] really unlocks the potential hidden …read more
Pyrotechnics are fun, and, with the proper precautions taken, safe enough to play with at home (usually). While it’s typical to purchase fireworks and smoke devices off the shelf, it’s actually possible to brew these up in a properly stocked home lab. [Tech Ingredients] is here to share the techniques behind producing your own super vibrant colored smoke devices at home.
Producing colored smoke requires a slightly different tack than making a simpler white smoke device. Colored smokes use dyes that are temperature sensitive, and thus the reaction temperature must be controlled carefully. This is achieved by choosing a potassium …read more

It’s that spooky time of year once again, with pumpkins and cobwebs as far as the eye can see. This year, [Mikeasaurus] has put together something really special – a Ghost Rider costume with some amazing effects.
The costume starts with the skull mask, which started with a model from Thingiverse. Conveniently, the model was already set up to be 3D printed in separate pieces. [Mike] further modified the design by cutting out the middle to make it wearable. The mask was printed in low resolution and then assembled. [Mike] didn’t worry too much about making things perfect early on, …read more
Smoke is a useful thing, whether you want to hide from enemy combatants or just make a big scene at a local sporting match. Smoke devices have lots of applications, many of which will likely cause a nuisance to somebody, somewhere. With that said, they can also be really cool, and [Tech Ingredients] is here to tell you how to make them.
Far from a simple tutorial, the video guide is loaded with detail. It begins with an explanation of the basic chemistry involved, using potassium nitrate and sugar. This is the basis of rocket candy, a popular method for …read more
What good is safety gear that isn’t used because it’s annoying and gets in the way of getting the job at hand completed? None, really, and the solder fume extractor is one item that never seems to live in harmony with your workspace. They’re often noisy, they obstruct your vision, and a power cord draped across your bench is a sure way to ruin your soldering zen.
To fix those problems, [Nate] has built a nice battery powered solder fume extractor that’s so low profile and so quiet, you won’t mind sharing a bench with it. Based on a standard …read more

Who would have thought that you could light up pyrotechnics on USB power? This USB keystroke injector that blows up after it’s used proves the concept.
Fully aware that this is one of those “just because you can doesn’t mean you should” projects, [MG] takes pains to point out that his danger dongle is just for dramatic effect, like a prop for a movie or the stage. In fact, he purposely withholds details on the pyrotechnics and concentrates on the keystroke injection aspect, potentially nasty enough by itself, as well as the dongle’s universal payload launching features. We’re a little …read more
