Math & Numbers

Mechanical Efficiency Calculator

Calculate the efficiency of a mechanical transmission (gearbox, belt, chain, etc.). η = P_out / P_in, returning the efficiency percentage and the power loss P_loss = P_in − P_out.

Network

MTU / MSS Path Calculator

Calculate how much each tunnel or encapsulation layer consumes from your interface MTU, the effective TCP MSS, and the DF ping probe size. For SRE, SD-WAN, and k8s CNI engineers.

Health

Macro Calculator (Carbs / Protein / Fat Split)

Convert a daily calorie target into grams of carbohydrate, protein and fat. Pick a preset split — balanced (50/30/20), low-carb (35/40/25), keto (10/20/70) or high-protein (40/35/25) — or define your own percentages.

Games

Magic 8 Ball

The classic Magic 8 Ball. Ask any yes-or-no question, shake, and get one of 20 traditional answers (yes / no / uncertain). Classic English phrases or localized translations.

Games

Mastermind Game

Classic Mastermind code-breaking game. The computer picks a secret color code; you guess row by row. Black pegs = right color and position; white pegs = right color, wrong position.

Media

Media Metadata to JSON

Extract audio/video metadata as JSON with ffprobe.

Math & Numbers

Kinetic Energy Calculator (KE = ½mv²)

Compute kinetic energy, mass, or velocity from the other two, with momentum and km/h conversion

Calculator

Mulch Gravel Soil Bulk Bag Estimator

Estimate how much mulch, gravel, topsoil, river rock, sand or compost a landscaping job needs. Enter the area shape (rectangle, circle, triangle or tapered bed/border), dimensions and depth, then pick a material from the built-in density table (or a custom density). The estimator returns volume (m³ / liters / yd³ / ft³), weight (kg / lb / tonnes), the count of 1 m³ or 1 yd³ bulk bags, small retail bag count, optional cost, plus depth and allowance warnings. Metric and imperial units supported.

Security

Nonce & Token Generator

Generate cryptographically secure one-time tokens for web security scenarios — CSRF tokens, OAuth/OIDC state parameters, session nonces, and PKCE code_verifier/code_challenge (S256). Uses crypto.randomBytes, never Math.random.

Development

JSONPath REPL Playground

An interactive JSONPath REPL that runs multi-step query pipelines against any JSON. Write one JSONPath expression per line (e.g. $..book[?(@.price<10)] then $[0:5]) and see each step's matches with counts, paths, and values — plus a shareable URL that encodes your data and pipeline. Supports recursive descent ($..), wildcards ([*]), filters ([?(@.price<10)]), slices ([0:5:2]), and negative indices.

Validation

Luhn Checksum Calculator

Validate or generate numbers using the Luhn algorithm (mod-10). Works for credit cards, IMEI, IMEISV, SIN, NPI and any custom Luhn-based identifier.

Development

Markdown Link Checker

Statically check Markdown links for format errors, broken anchors, and undefined references (no network requests)
