○Open: public page gives enough substance to understand the site $Paid: pricing, booking, ecommerce, subscription, or paid access is visible ADAds: visible ad load or ad-supported content ✦Pretty: notable design, copy, craft, or presentation ◆Pro: polished, finished-feeling, serious, or operationally mature ◇Niche: specific audience, workflow, or unusually focused use case ◉Human: personal, local, community, civic, handmade, or real-person signal !Suspicious: scammy, spammy, trust theater, finance fog, or credibility concern

A free, browser-based toolkit for shop math, machining calculators, technical references, and practical guides.

Why it surfaced

BT Engineering gathers the calculations that normally live on a shop wall or in scattered handbooks: thread dimensions, tap drills, speeds and feeds, GD&T, insert decoding, material data, surface finish, and bar economics. Its guides get unusually concrete about problems like work-hardening stainless, chatter, burrs, and when to drill larger on purpose—and the site says the tools work offline without a login.

Ham Is Specifically Discouraged

August 10’s newborn domains include a mock cryptid council that specifically discourages ham, a vintage phone collecting messages for Twyla’s 70th, a 4.5-meter dish measuring Galactic hydrogen at 1420 MHz, and an open index that found 530 sites permitting GPTBot in robots.txt while refusing it at the server.

This is one of 1,000 discoveries in the 2026-08-10 Domain Arrivals issue.
