When you think about additive manufacturing, thoughts naturally turn to that hot-glue squirting CNC machine sitting on your bench and squeezing whatever plastic doodad you need. But 3D printing isn’t …read more Continue reading Electrospinning Artificial Heart Valves
It used to be that nearly every home had at least one decent high-voltage power supply. Of course, it was dedicated to accelerating electrons and slamming them into phosphors so …read more Continue reading High-Voltage Fun with an Inexpensive Power Supply
For the most part, here at Hackaday we’re more interested in how something was made than the backstory on why an individual actually put it together. Frankly, it’s not really …read more Continue reading 20,000 Volt plasma Knife Slices, Dices, and Sparks
When you have a bunch of 230 kV transmission lines running over your property, why not use them for some scientific experiments? This is where the [Double M Innovations] YouTube …read more Continue reading Harvesting Electricity From High-Voltage Transmission Lines Using Fences
When you set out to build a 60,000-volt power supply and find out that it “only” delivers a measly 50,000 volts, you naturally have to dive in and see where …read more Continue reading Lessons Learned from a High-Voltage Power Supply
It’s not entirely clear why [Advanced Tinkering] needs a 50,000-volt power supply, but given the amount of work he put into this one, we’re going to guess it will be …read more Continue reading An Adjustable High-Voltage Power Supply Built with Safety in Mind
While vacuum electronic devices have largely been superseded over much of consumer electronics, there’s one place where they can still be found for now. The cavity magnetron is a power …read more Continue reading Powering A Cavity Magnetron, From A Battery
We’ve got to say that [Les Wright] has the most fun on the internet, at least in terms of megawatts per dollar. Just look at his new video where he …read more Continue reading Tattoo-Removal Laser Brought Out of Retirement for a Megawatt of Fun
We’re willing to bet most Hackaday readers have accidentally spot welded a few electrical contacts together over the years, complete with the surge of adrenaline that comes with the unexpected …read more Continue reading Wiring Up 100 Car Batteries So You Don’t Have To
