While our desktop machines are largely limited to various types of plastic, 3D printing in other materials offers unique benefits. For example, printing with concrete makes it possible to quickly …read more Continue reading Robot 3D Prints Giant Metal Parts with Induction Heat
Like the incandescent bulb before it, the compact fluorescent (CFL) bulb is rapidly fading into obscurity as there are fewer and fewer reasons to use them over their LED successors. …read more Continue reading New Possibilities from Fading Lighting Technology
There’s nothing quite like old-school electrical gear, especially the stuff associated with power distribution. There’s something about the chunky, heavy construction, the thick bakelite cases, and the dials you can …read more Continue reading A Look Inside an Old-School Synchroscope
Induction cook tops are among the most efficient ways of cooking in the home that are commercially available to the average person. Since the cook surface uses magnetic fields to …read more Continue reading Induction Heater Uses New Coil
Like many hackers, [Matthias Wandel] has a penchant for measuring the world around him, and quantifying the goings-on in his home is a bit of a hobby. And so when …read more Continue reading Using Homebrew Coils to Measure Mains Current, and Taking the Circuit Breaker Challenge
Transformers have an obvious use for increasing or decreasing the voltage in AC systems, but they have many other esoteric uses as well. Electric motors and generators are functionally similar …read more Continue reading Keep Coffee Warm Through Induction Heating
For decades, people without access to kitchens (such as college students) have cooked meals on portable electric hotplates. The Bonbowl gives that concept a modern makeover, by incorporating faster, more efficient induction heating technology.Continue … Continue reading Bonbowl is a high-tech take on the humble hotplate
Induction heaters can make conductive objects incredibly hot by generating eddy currents within the metal. They’re used in a wide variety of industrial processes, from furnaces to welders and even heat treatments. [Schematix] whipped up his own design, and put it through its paces on the bench.
The build in …read more

Electric utilities across the world have been transitioning their meters from the induction analog style with a distinctive spinning disc to digital “smart” meters which aren’t as aesthetically pleasing but do have a lot of benefits for utilities and customers alike. For one, meter readers don’t need to visit each …read more
Machinists have a lot of neat shop tricks, but one especially interesting one is shrink-fitting tools. Shrink-fitting achieves an interference fit between tool and holder by creating a temperature difference between the two before assembly. Once everything returns to temperature, the two parts may as well be welded together.
The …read more
