Tools & Web Apps

D&D 5th Edition encounter calculator

A tool for working out the difficulty of a given Dungeons and Dragons encounter, or calculating an appropriate challenge for your party. It can use either the XP rating or the CR of the monster(s).

The calulator is based on the D&D DM Basic Rules, available for free on the Wizards of the Coast website. These happen to be the same rules that are used in the Dungeon Master's Guide.

You Should Spend Your Money On

Are you or your players sat on a veritable hoard of treasure and stuck for ideas? YSSYMO randomly suggests things your D&D character could spend their hard-won gold on.

Split Test Calculator

A simple split-test calculator for testing PPC ads, though it can be used to test statistical significance between two populations more generally.

The calculator is based on Jim Ryan's page on the Chi-Square statistic.

Kerbal Space Planner

(Unfortunately outdated, written for KSP v0.22) ksplanner is a browser-based VAB planning tool that allows you to piece together stages with stock parts, and automatically calculates mass, Delta-V and TWR on various celestial bodies within the Kerbol system.

A quick and dirty converter to take content formatted by MS Word and spit out (relatively) safe HTML.
