Online Tools

This page provides online tools with interactive figures you can touch, covering knowledge of control and equipment design, for engineers and technicians who work on software and networks for production equipment. The author and fellow practitioners have gathered the tools they wanted. Please make use of them.

Flagship tools

Operator panel and HMI color review toolkit

An HMI panel with a small picker on the right, for bezel then text. The ring drives the frame first; its path then changes and the letters follow. This frame has the cursor in the picker, a teal bezel, and RUN in another color.

QR code generator for part marking

A part-marking QR as a generate-then-soil scan trial, with a guide percent and a meter. Dirt on the trial overlay lowers the guide; the mark file stays clean. This frame is stacked soil and glare, with the meter down at 30%.

CIDR / Subnet Visualizer

An IPv4 address split at the prefix into network and host bits. Moving /24 to /25 halves the host block; cables do not. This frame is the /25 cut: host cells parted into two nets at .0 and .128.

World Timezone Map

A world map of city clocks against the solar day/night line. Clocks follow official UTC; shade is sunlight, not zone borders. This frame: sunlit Pacific, night on Europe, Africa, and eastern North America; Tokyo, London, New York.

Percentages for design and the shop floor

A yield grid of good pieces inside the started count. The percent is good ÷ started, not the leftover as defects. This frame is 84 green cells of 100, marked 84%.

Logo ASCII for source and README

Hurricane & Typhoon History Map

A world timeline of tropical cyclone tracks, colored by how strong each storm was. The year moves; the path paints intensity. This frame is 2013, Haiyan crossing the western Pacific in Cat 5 red.

Engineering PDF Toolkit

A drawing-set PDF with mixed page turns, aligned then gathered into one pack. A3 and A4 stay; only the turn changes. This frame is the four sheets stacked on the left, all portrait, after the clockwise align.
