SHILAJIT IMMERSION: DEATH LOGISTICS AND TIMELINE CALCULATOR
Enter your height and weight, and it calculates the step-by-step logistics and timeline of sinking to your doom in a giant vat of shilajit resin. Educational? Sure. Necessary? Absolutely.
RESEARCH ARCHITECT: OUTLINER and SOURCE MANAGER
A single-file research outliner that runs locally in your browser. Build nested outlines, add a source library, and insert citation keys directly into notes. Auto-saves to local storage (so your work is still there when you return), and exports clean JSON, Markdown, and BibTeX for easy backup and portability.
PYRAMID SCALE-MODEL BLUEPRINT CALCULATOR
Choose a historical pyramid profile (Khufu, Khafre, Menkaure, Red, Bent, Meidum), set a height, and it scales base, slant height, edge length, surface area, and volume. Shows face angle and ancient seked (palms/fingers per cubit). Exportable PDF spec sheet.
HYPER-CUBE QUICK-STATS: n-Dimensional Tesseract Calculator
Enter an integer "n" to get counts for faces, edges, vertices, and other geometric delights.
ELECTRIC SIGIL CIRCUIT BUILDER
Converts names or phrases into functional electronic schematics: closed-loop circuits, SVG diagrams, SPICE netlists, and layouts for perfboard/stripboard. Practical and divinatory... I hope. Persons who decide to build and test a live electrical circuit using this tool do so at their own discretion; I am not responsible if you or anyone else gets electrocuted. Either way: neat tool, man!
Enter a date (time optional) and it snaps the Sun to its 10° decan. Flip between Tropical bins or an Egyptian decan scaffold, switch "Scribe's Sky" vs "Temple Lore" modes, and view it on an ecliptic band with a Sun pin. Exportable PDF.
