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
In settings such as disaster sites, toxic gas leaks can pose a real risk to rescue teams. With that in mind, Spanish researchers have outfitted a small drone to go into buildings and check for such gases, before anyone enters…

A shelter-in-place advisory was issued for thousands of Houston suburb residents after a four-day blaze released chemicals into the air. Continue reading A Massive Petrochemical Fire In Texas Released Toxic Benzene Into the Air
A team heated a cloud of gas up to 2,000°F and blasted it with radiation to see what happens on giant planets that orbit very close to their stars. Continue reading NASA Scientists Created a Super-Hot Exoplanet Atmosphere on Earth
A new report estimating the carbon emissions for 2018 shows they have risen for the first time in four years, in part due to the growing economy. Continue reading A Strong US Economy Doesn’t Have to Mean a Worse Climate
If you want to visualize sound waves, you reach for your oscilloscope, right? That wasn’t an option in 1905 so physicist [Heinrich Rubens] came up with another way involving flames. [Luke Guigliano] and [Will Peterson] built one of these tubes — known as a Rubens’ tube — and will show you how you can, too. You can see a video of their results, below. Just in case a flame oscilloscope isn’t enough to attract your interest, they are driving the thing with a theremin for extra nerd points.
The guys show a short flame run and one with tall flames. …read more
The molar mass of carbon monoxide (CO) is 28.0, and the molar mass of air is 28.8, so CO will rise in an ambient atmosphere. It makes sense to detect it farther from the ground, but getting a tall ladder is not convenient and certainly doesn’t make for fast deployment. What do you do if you don’t care for heights and want to know the CO levels in a gymnasium or a tall foyer? Here to save the day, is the Red Balloon Carbon Monoxide Detector.
Circuit.io generates the diagram and code to operate the CO sensor and turn a …read more
Old solutions are often so elegant and effective that they keep coming back. The gasometer, or gas holder, is one such example. Now [NightHawkInLight] has built one for storing the wood gas he’s been experimenting with, and it’s pretty neat to watch it rise and fall as he first adds gas and then burns it off. The mechanism couldn’t be simpler.
For those who like us are hearing about this low tech for the first time, gasometers are a means of safely storing gas stemming from the 1700s when gas was king and electricity was little more than a gentleman …read more

When life hands you the world’s smallest chainsaw, what’s there to do except make it even more ridiculous? That’s what [JohnnyQ90] did when he heavily modified a mini-electric chainsaw with a powerful RC car engine.
The saw in question, a Bosch EasyCut with “Nanoblade technology,” can only be defined as a chainsaw in the loosest of senses. It’s a cordless tool intended for light pruning and the like, and desperately in need of the [Tim the Toolman Taylor] treatment. The transmogrification began with a teardown of the drivetrain and addition of a custom centrifugal clutch for the 1.44-cc nitro RC …read more
