In plain words
Satoshi9000 is a mechanical device that generates Bitcoin private keys by converting physical analog randomness into digital randomness. The machine operates air-gapped without electronic components, allowing users to understand and verify the key generation process. Beyond cryptocurrency, it can be applied to randomized clinical trials and other scenarios requiring transparent, verifiable randomness that is understandable to both technical and non-technical audiences.

I built this machine so I could generate Bitcoin keys that I could trust. Air-gapped and simple to use and understand (mechanical). The Satoshi 9000 demo: https://youtu.be/bJiOia5PoGE The key value proposition of the machine is that it generates analog randomness in the physical world and converts it into digital (1’s and 0’s) randomness. Seamlessly. But it occurs to me that it may have other uses beyond crypto keys for your own use, such as: * Randomized clinical trials. Clinical trials need a high degree of transparency for ethical reasons; also, for legal reasons should it come to light after the trial has ended that patient selection and treatment selection was not random or in some way biased (say, by the researchers themselves). The machine described herein can provide that transparency to young and old patients, technical and non- technical. * Non-technical management. Many network engineers in need of security keys have bosses that are non-technical. Such managers might prefer security keys (and their generation) which are easier for them to understand. * Estate planning. Suppose members of a family were to inherit digital assets (such as Bitcoin, for example). Not all members of the family are technical and understand Bitcoin. However, each will still need to generate a secure Bitcoin key to receive their share of the inheritance. The machine described herein might help in that task because its source of randomness is more easily understood by laypeople and each can generate their own private key in private (in isolation with the machine). * Anywhere where the users have to have an intuitive understanding of how the randomness is being created; whether they are 5 years old, or 95 years old, and all ages in between. I'm curious to know if any of the folks over at HN can think of other use cases?

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:…
