Operations Toolchest
The Ops Stack is being refocused into a cleaner library of educational insights, DIY builds, free entry-level tools, and upgraded operator packs for people who like making useful technical things.
New Direction
Insights teach the why, Labs show the build, Toolchest gives the starter asset, and paid packs can later extend the workflow without burying the basics.
Field Notes
A short field-notes email is on the roadmap. For now, the site is focused on publishing clean guides and lab builds first.
