A handful of Hacker News commenters shared personal toolkits sparked by recent AI advances. One user described crafting ceramic molds and wooden templates for glass work, emphasizing the tactile satisfaction of physical aids. Another built a tiny CLI that generates 2FA codes, shortcutting phone entry and storing results on the clipboard. Others mentioned remote image viewers for VMs and a YouTube video summarizer.

A developer leveraged an LLM to write a DSL interpreter that outputs CAD files via cadquery, enabling rapid design of science‑inspired jewelry such as lambda‑diagram pendants. Because LLMs falter on 3D orientation, the workflow creates several axis drawings and selects the proper view. The same model helped a non‑technical spouse assemble an online store, now live at studio‑galois.com.

Other contributors posted open‑source repos ranging from Otzel, an Elixir operational‑transform library claimed to run 50× faster than the popular alternative, to Spector, a lightweight CQRS framework, and a TUI sermon authoring tool with parallel Bible view. One repo, nanodrop, links Elixir to spectrophotometers for lab automation. Collectively these projects show AI significantly lowering friction for niche engineering tasks.
