Photometry & Lighting API

salutare 3,220 Abbonati

Photometry and lighting maths as an API, computed locally and deterministically. The illuminance endpoint computes the light falling on a surface from a point source, E = I·cos(θ)/d² in lux, from the luminous intensity in candela, the distance in metres and the angle of incidence from the surface normal — a 1000 cd source straight down at 2 m gives 250 lux. The inverse-square endpoint scales a known illuminance to a new distance, E2 = E1·(d1/d2)², so doubling the distance quarters the light. The flux-intensity endpoint converts between luminous flux in lumens and luminous intensity in candela through the solid angle, I = Φ/Ω and Φ = I·Ω, with the solid angle taken as the full sphere 4π steradian for an isotropic source or, for a spotlight of full beam angle β, Ω = 2π·(1 − cos(β/2)) — so a 100 cd isotropic source emits about 1256.6 lm, and a 1000 cd lamp in a 30° beam emits about 214 lm. Distances are in metres and angles in degrees. Everything is computed locally and deterministically, so it is instant and private. Ideal for lighting-design, architecture, photography, film, horticulture-grow-light, stage and AV app developers, lux-and-lumen and luminaire-planning tools, and engineering software. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. These are photometric (perceived-light) quantities; for blackbody/peak-wavelength radiometry use a Wien/radiation API.

Lighting Calculator API

Lighting design maths as an API, computed locally and deterministically. The room endpoint works out how many lumens a room needs from its area and a target illuminance — given directly in lux or chosen from a room-type preset (living, kitchen, office, workshop and more) — and, optionally, how many fixtures at a given lumen output and how many watts at a given lamp type. The lux endpoint converts between lux, footcandles and lumens over an area, so you can find the illuminance from a light output and a room size or vice versa. The efficacy endpoint relates lumens, watts and luminous efficacy (lumens per watt): give any two — or a lamp-type preset such as incandescent, halogen, CFL or LED — and it computes the third. Everything is computed locally and deterministically, so it is instant and private. It is a lumen-method estimate: target levels are typical guidance (EN 12464 / IES) and a full design would add room and utilisation factors. Ideal for lighting and electrical tools, interior-design and home apps, retrofit and energy-saving calculators, and smart-home planning. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is illumination maths; for Ohm's-law electrical quantities use an electronics API.

Color Temperature API

Turn physical light into RGB colours — entirely locally. The kelvin endpoint converts a colour temperature in Kelvin into the RGB colour of a black body at that temperature: warm candle and incandescent tones below 3000 K, neutral and daylight whites around 5000–6500 K, and cool bluish light above, using Tanner Helland's widely-used approximation and returning hex, an rgb() string and a plain-English description (candlelight, warm white, neutral, daylight, cool). The wavelength endpoint converts a wavelength of visible light in nanometres (380–780 nm) into the approximate RGB colour the human eye perceives, with the natural intensity fall-off at the violet and red edges of the spectrum, and names the band (violet, blue, cyan, green, yellow, orange, red). Everything is computed locally and deterministically, so it is instant and private. Ideal for lighting and smart-bulb apps, photography and white-balance tools, data-visualisation of temperature or spectra, theming and UI accents, and science and education. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. These are perceptual approximations, not colorimetric CIE conversions; for hex/RGB/HSL conversion and palettes use a colour API.

Egg Incubation API

Egg-incubation maths as an API, computed locally and deterministically — the hatch timeline, conditions and brooder numbers a hatchery or backyard chicken-keeper raises a clutch by. The hatch endpoint turns the set day (day 0) into the schedule by species: it knows the incubation period — chicken 21 days, duck 28, quail 17, goose 30, turkey 28, Muscovy 35 and more — and gives the lockdown day, about three days before hatch, when you stop turning the eggs, raise the humidity and leave the lid shut; pass a custom incubation_days for anything else. The conditions endpoint gives the targets: a forced-air incubator at 99.5 °F (still-air a degree or two higher at the top of the eggs), with humidity around 45–55 % through incubation and 65–75 % at lockdown so the membrane stays soft. The brooder endpoint schedules the chicks after they hatch — 95 °F under the lamp in week one, dropping 5 °F a week until they reach room temperature around 70 °F and are feathered enough to leave it. Everything is computed locally and deterministically, so it is instant and private. Ideal for poultry, hatchery, homesteading and farm app developers, incubation-timer and brooder tools, and 4-H / education software. Pure local computation — no key, no third-party service, instant. Guidance — candle the eggs and watch the chicks. Live, nothing stored. 3 compute endpoints.

Vegetable Fermentation API

Vegetable lacto-fermentation maths as an API, computed locally and deterministically — the salt numbers a fermenter weighs sauerkraut, kimchi and pickles by. (Vegetables, not meat — for cure and nitrite that is a separate calculation.) Salt is the whole game: too little and the wrong microbes win, too much and the ferment stalls. The salt endpoint does the dry-salt method for shredded veg, salt = vegetable weight × percent, with about 2 % being the classic sauerkraut and kimchi target — so a kilo of cabbage takes 20 grams — and it bands the result from low-and-fast to a near salt-cure. The brine endpoint sizes a submerged ferment, salt = water weight × percent where the percent is of the water as recipes state it (1 ml water ≈ 1 g), so a litre at 5 % needs 50 grams for a standard sour pickle, 3.5 % for a milder one; it also reports the salinity as a percent of the total solution. The salinity endpoint converts the two ways the same brine is expressed — percent of water versus percent of total — so a 5 %-of-water brine reads about 4.76 % on a refractometer. Everything is computed locally and deterministically, so it is instant and private. Ideal for fermentation, homesteading, recipe and food app developers, ferment-calculator and batch tools, and culinary software. Pure local computation — no key, no third-party service, instant. Grams and ml. Live, nothing stored. 3 compute endpoints.
