Before small #cockroft-walton multipliers became inexpensive x-ray machines used to use large iron transformers. These things are the highest voltage transformers you'll likely ever come across, turning 120V (or 240V in euroland) into 50,000V, 75,000

Humans of the internet, I present to you the BlitzenKlavier (lightning-piano). It’s a large solid-state Tesla coil that takes in 120VAC, MIDI, and spits out 8 foot musical lightning bolts! [img]../storage/fragment_images/42879498820102740_cd3fac28b4

Also referred to a Line Output Transformer, the flyback transformer is a high frequency, high voltage transformer most often used to power cathode ray tubes. Flybacks are capable of generating some decently high voltages, typically anywhere from 10 to 35k

For whatever reason, Vedder never added shut down to the VESC 6.0, despite the power supply chip having this capability. Here is how to add it. [t]You will need...[/t]The following components: [ul][li]10K Resistor[/li][li]3.3V Zener Diode[/li][li]

Tektronix sent me a new TDS2024C! Now what do we do with new $1500 toys? WE RIP THEM APART (⌐■_■)っ═一 [t]The Finish[/t]Let’s look at this one from behind. Not much going on there, apart from a USB device port, FCC information, a kens

Transformers are not the only way one can boost voltage; another method to the madness is a Cockroft-Walton multiplier, or thes the Villard Cascade depending on your favorite dead scientist. “CWs”, as they are colloquially known, are a charge pump use

Ladies and gentlemen of teh internetz, I present to you a marvelous device that will revitalize your health and bring wondrous wealth and prosperity to your families and all future generations. Straight from Nikolai Tesla's labs I bring you a fantast

STMicro’s documentation about the subject is some of the most terse documentation I’ve ever seen in the business! This cheat sheet is a work-in-progress. The STM32 microcontroller family has 2 DMA controllers, and 16 DMA “streams”. Streams are

I've seen multiple designs for a plasma speaker online, and quite frankly most of them are not very good. Some problems I noticed were constantly blowing up MOSFETs, distorted audio, excessive heating of the MOSFET(s) etc. I was shown a nice circ

You don't need lots of money to make high voltage capacitors, in fact some pretty decent ones can be made with some cheap and readily available materials. This is because capacitors are very simple devices consisting only of a dielectric and two plat

The microwave oven transformer is possibly one of the simplest methods of making some big high voltage arcs, mainly because they are robust, cheap, and easy to hook up.[img]../storage/fragment_images/79114536969562370_d47432c45ed03f967dbf1445f547852c.jpg[

A "ZVS driver" is a self resonant oscillator; a very simple circuit that can oscillate a large amount of power with little loss. It is normally used for making the sine wave needed for driving high frequency transformers such as those found in L

Never put an electrolytic capacitor in backwards. [youtube]3b7mjukhTyQ[/youtube][t]Why it happens[/t]Electrolytic capacitors are constructed using an electrolyte-soaked piece of paper between two strips of aluminum foil. One piece of foil is oxidized

It is a tale very commonly told that Lead Acid batteries are a “cheaper” solution than Lithium batteries for off-grid and solar storage. As of 2019 that is patently false, and the purpose of this article is to explain how this remarkable fact comes to
