What it does
Free generator wattage calculator. Select your appliances, calculate total watts needed, and get the right generator size recommendation with fuel cost estimate.
Our calculator uses the NEC (National Electrical Code) Article 220 methodology to determine the right generator size for your home. This is the same standard used by licensed electricians across the United States. This approach is more accurate than simply adding all appliances together, because it accounts for the fact that not all appliances run at the same time . Per NEC 210.20(A) , continuous loads should not exceed 80% of a circuit's (or generator's) rated capacity. This means: For essentials (fridge, lights, window AC, TV): 5,000-7,500W . For whole-house with central AC: 10,000-15,000W . Running: 150-400W . Starting: 600-1,200W . Energy Star models use less. Because you don't run all…from pickmywatt.com

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
