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
In the “don’t try this at home” category, [Joe Smith] builds a spark gap transmitter with a twist. The twist is that the drive power is from a signal generator …read more Continue reading Modern Spark Gap Transmitter Uses a Rotary Gap
[Rostislav Persion] has for some time been interested in making small, portable EMP devices capable of interfering with nearby electronics. In these EMP devices, high voltage is used to create …read more Continue reading Scrambling Pocket Calculators Made Easy With EMP Box V2
When it comes to high-speed, high-voltage switching, there are a wealth of components to choose from — MOSFETS, thyristors, IGBTs, and even vacuum tubes like thyratrons. But who needs all …read more Continue reading Spark Plug and Plumbing Parts Bring Nitrogen Laser Under Control
[Petteri Aimonen] presents for us a modular differential probe, as his entry into the 2021 Hackaday Prize. This project shows a simple and well polished implementation of a differential-to-single-ended preamplifier, …read more Continue reading This Modular Differential Probe Shows Great Attention To Detail
Ah, what fond memories we have of our misspent youth, walking around with a 9,000-volt electromagnetic pulse generator in our Levi’s 501s and zapping all the electronic devices nobody yet …read more Continue reading Is that an EMP Generator in Your Pocket or Is My Calculator Just Broken?
Normally, we think of lasers as pretty complex and fairly intimidating devices: big glass tubes filled with gas, carefully aligned mirrors, cooling water to keep the whole thing from melting …read more Continue reading The Devil is in the Details For This Open Air Laser
Hardware fault injection uses electrical manipulation of a digital circuit to intentionally introduce errors, which can be used to cause processors to behave in unpredictable ways. This unintentional behavior can …read more Continue reading Injecting Bugs with an Electric Flyswatter
Tesla Coils are a favourite here at Hackaday – just try searching through the archives, and see the number of results you get for all types of cool projects. [mircemk] adds to this list with his Extremely simple Tesla Coil with only 3 Components. But Be Warned — most Tesla …read more

You’d be forgiven for assuming that a Tesla coil is some absurdly complex piece of high-voltage trickery. Clarke’s third law states that “any sufficiently advanced technology is indistinguishable from magic”, and lighting up a neon tube from across the room sure looks a lot like magic. But in his latest …read more
