I’m a polymath who tackles hard problems. I love drawing ✍️, inventing 🛠️, computers 💻, electricity ⚡️, and many forms of art 🎹 and science 👩🔬.
I hope you find my chapter of Civilpedia an inspiring place to be 💖.

Franklin's Bells
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
Voltage Multipliers
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
Particle-induced Air Ionization
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
Nuclear Bomb Detector
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
Ol' Sparky
So here's the story: I ended up getting 8 fancy high voltage capacitors in a trade with @inducktion, and they ended up sitting on my shelf for about a month. A couple weeks later I came across a reel of 5000 glass 1kV ultrafast diodes on ebay, and af
Greenhouse Gas Camera
A camera that captures video footage of CO2, NOx, SO2 and other gas emissions from from vehicles, power plants, gas flares, would be pretty cool. Let's make one! [img]../storage/fragment_images/63957192955728260_037c0ce694352e685bb52f296e103ded.j
Radiation Safety
Nonionizing radiation, the stuff of microwave, infrared and visible light doesn’t have the energy needed to break chemical bonds, so we may sit out in the sun and get bombarded with a thousand watts and feel no ill effects. Once we reach ultraviolet tho
Coolidge Tubes
Invented in 1913 by William D. Coolidge, the Coolidge tube is by far the most popular method used to generate x-rays. Essentially it’s just a thermionic diode, but one optimized for high voltages and high powers. Like a thermionic diode a Coolidge tube
Propane Gas Camera
I did some experiments today with trying to detect propane using a 3.33um filter. This filter is selective for methane, which should be inside "natural gas" in detectable amounts. My first experiment was to see if I could see the gas c
