Just as the gold standard for multimeters and other instrumentation likely comes in a yellow package of some sort, there is a similar household name for thermal imaging. But, if …read more Continue reading Pocket-Sized Thermal Imager
The discovery was founded on the useful, but confusing idea of quasiparticles, which act as if they exist, but really don’t. There are only three types of particle in a solid: protons, neutrons and electrons. When packed together in a solid, these indi… Continue reading Researchers predict, then prove strange solid-state heat switches
One of the great things about the Hackaday community is how quickly you find out what you don’t know. That’s not a bad thing, of course; after all, everyone is …read more Continue reading A Single-Resistor Radio Transmitter, Thanks to the Power of Noise
The term “adaptive optics” sounds like something that should be really complicated and really expensive. And in general, the ability to control the properties of optical elements is sufficiently difficult …read more Continue reading A Tiny Forest of Resistors Makes for Quick and Dirty Adaptive Optics
[D. Scott Williamson] paid $5 for a Roland JV-30 synthesizer at a garage sale. Score! There was only one catch: it didn’t work and didn’t include the power supply. Luckily, …read more Continue reading Restoring $5 Busted Synthesizer Made Easy, Thanks to Thermal
Wind and solar power are intermittent, generating power when it’s available rather than when it’s needed, so the green energy transition will require huge amounts of energy storage. This could end up taking many forms, from conventional lithium-based “… Continue reading World’s first commercial sand battery begins energy storage in Finland
Most of us either own or have used a laptop at some point. For traveling, as a student, or even for browsing Hackaday on the couch in front of the …read more Continue reading Desktop Performance In A Custom Mac Laptop
The extremely hot interior of the Earth is slowly cooling down, but exactly how fast remains unknown. By studying how well a common deep-Earth mineral conducts heat, researchers from Carnegie and ETH Zurich have found that the planet’s interior may be … Continue reading Earth’s interior may be cooling down faster than we thought
Berkeley Lab engineers have developed a roof coating that can keep a building warmer or cooler, depending on the weather. When it’s warm out, the material will reflect sunlight and heat, but this radiative cooling automatically switches off in winter, … Continue reading Smart roof coating reflects heat in summer and traps it in winter
We wouldn’t go so far as to say “don’t try this at home”, but the way [Troy] brought an expensive (but out of warranty) laptop back to life is interesting, …read more Continue reading Laptop Gets Fixed by Simply Removing Problem Component
