Physics, color, media, and protocol expansion

Another hundred tools landed across seven themes—physics and stats, text encodings, digests, response-header parsers, accessibility color math, and media sizing. Start here when you know the job, not the route name.

The newest Toolcore batch adds another hundred browser-local pages in physics math, text and cipher utilities, checksums and encodings, HTTP/DNS header parsers, WCAG color math, and media sizing helpers. Use this map when you already know the task—not when you want to scroll the full catalog.

Physics, surfaces, and probability

Sphere, cone, and cylinder surface area — geometry homework and CAD sanity checks.
Ohm's law, kinetic energy, and P = VI — quick electronics and mechanics estimates.
Bayes theorem, birthday paradox, and linear regression slope — stats drills and spreadsheet double-checks.

Morse, binary, and light ciphers

Educational and puzzle-oriented—pair with the security checks article before you paste real secrets.

Morse encode / decode and Braille.
Vigenère decode, Caesar decode, and Atbash.
Text ↔ binary, find hashtags, and count sentences.

Digests, Base58, and quoted-printable

SHA-512, FNV-1a, and password entropy bits.
Base58, Z85, and quoted-printable.

Headers, WCAG contrast, and media math

Cache-Control parse, Link header, and DNS TXT parse.
WCAG contrast ratio and relative luminance — accessibility checks without leaving the browser.
Aspect ratio fit, video bitrate estimate, and DPI to pixels.

Common use cases

Estimate sphere or cylinder surface area and check Ohm's law or kinetic energy on a lab worksheet.
Decode Morse or Vigenère ciphertext and convert pasted prose to binary or hex for encoding exercises.
Parse Cache-Control or Link response headers and compute WCAG contrast between two hex colors.

Common mistakes to avoid

Using classical ciphers for real secrets
Caesar, Vigenère, and Atbash pages are educational. Use the Security hub and security checks article for tokens and keys.
Treating DNS TXT parse as live DNS lookup
Paste the record text you already have—the tool splits tokens locally; it does not query resolvers.
Assuming WCAG contrast replaces manual audit
Contrast ratio math helps early design passes; production sign-off still needs full context (font size, states, branding rules).

FAQ

How does this batch differ from the finance batch?

That guide covered loans, case converters, and SPF/DMARC. This set adds physics formulas, Morse/ciphers, Base58/Z85, HTTP cache headers, and color/media math.

Are all 100 pages linked here?

No—each section points to representative tools. Browse Math, Writing, Security, Encoding, Protocol, Color, and Media tabs for the full list.

Can agents prefill these tools?

Single text fields often accept q or qb. Multi-field physics and date tools open without URL prefill.
