I was born subservient to aggressive and abusive advertising, which pre-defined my life desires for me. This is a short story about how I set myself free. [img|h=60]../storage/fragment_images/9936629995201262_813f178572c538fd4bd3a362ba87c749.jpg[/

The nature of learning is understanding that newly-made humans can learn anything, because they don’t think they are unable to learn new information. So, if you learn to never enter a situation with prejudice about the way you think things should b

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

Recently, this "[url=https://www.indiegogo.com/projects/lomi-turn-waste-to-compost-with-a-single-button#/]automated composter[/url]" showed up in my instagram feed and I was curious about the carbon cost.  If it's reducing the compost

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]

In early 2018, friends and I decided to work on something rather unorthodox from our regular activities –we set out to bring new life into an old steel ship. Some of you whom are local to San Francisco may recognize the vessel, as it had been moored nea

It took a great deal of failure and subsequent reflection to recognize this not-so-obvious idea. It is very fashionable in the technology industry to build products which capitalize on people’s attention, but this is a scarce resource nowadays.

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

A personal challenge of mine is to elevate the human condition through improving institutional methodologies. Along these lines, it has been my experience that sharing can be more efficient, and more economical than hoarding. It’s no surprise that l

You might have heard about "functions" like sin, cosine, or absolute value before, but, what is a function really? A function, like most things in mathematics is an abstraction. It is a [b]map[/b], between elements of one set to another set

After their invention by Benjamin Franklin, Franklin’s bells became a novelty in the late 1700s. One bell would be connected to a stake in the ground while the other would be connected to a lightning rod, and a conductive clapper would be put in between

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

Alpha particles are very energetic little buggers. In fact, energies of 20MeV per particle are not uncommon. While this makes them incredibly dangerous if you happen to ingest something that emits them [radon, polonium] it can also make make for some rath

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

There are a few ways which we can describe the behavior of functions that can help us better understand what the function is going to do. [t]Monotonic Functions[/t]A function which is [b]monotonic[/b] is one where the function never changes "dire

Here is what I can best describe as a cold war era nuclear bomb detector. Whether or not such a device is good for anything is a matter of debate, but nonetheless I have here a few photos. On the outside, it looks like an innocent, albeit slightly hea
