Printstack – I'll print and post your Substacks to you
I've been turning individual Substacks into books -- actual paperbacks and hardbacks that you can put on your shelf -- for a little time now. (See the homepage.) So when a friend pointed me towards a tweet about doing it weekly across all a person's subscriptions, it seemed like a reasonable thing to test. I know where a few of the beartraps on the route from Substack to paper are. Do share feedback and thoughts.
In plain words
Printstack converts Substack newsletters into printed books, allowing subscribers to receive physical paperback or hardcover copies of their favorite publications. The service can compile individual newsletters or multiple subscriptions into bound volumes on a regular basis. It is designed for readers who want to collect and display their preferred Substack content in traditional book form on their shelves.

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:…
