IPv4 / CIDR subnet math for planning home and lab networks. Shows network, broadcast, host range and binary view.
Convert between image pixels, engraving size and DPI to choose sensible line intervals and dot spacing for laser jobs.
A small collection of handy converters: pixels <→ mm (with DPI), mm/inch/cm, and °C <→ °F for materials and workshop notes.
This space is reserved for future goodies: Base64 & hash tools, IP planners, engraving cheat sheets, and whatever else you dream up.
