Cyber Wolf

Design a sundial: drag ✋ the sun and watch 👀 the shadow sweep your dial.

Cyber Wolf is a sundial design bench. Choose where the dial will stand, pick its type ⌨️, and drag ✋ the sun across the sky. The shadow of the gnomon sweeps the dial you are designing, and the reading updates as you move.

Set up your dial

Pick a site 🏗️ from a list 📋 of cities, search 🔍 by name, drag ✋ a pin on the map, or type latitude and longitude.

Set the clock zone and the summer time ⏱️ rule for your region.

Choose a horizontal, vertical wall, reclining, polar, equatorial or ceiling mirror dial.

Turn the compass to set which way a wall faces, and set the tilt for a reclining plate.

Choose the plate size, longitude-corrected lines, the figure-eight, and monthly or solstice date lines.

Watch 👀 it work

Drag ✋ the sun on the sky strip. The dial reading, clock time ⏱️, altitude, azimuth and shadow length follow.

See 👀 the two dates in the year 🗓️ that share 🤝 the sun's declination.

Open the day card for sunrise, sunset, day length, solar noon and an hourly table 📋.

Follow the equation of time ⏱️ and the analemma through the year 🗓️, with the correction for your longitude.

Build 🔨 it

View the plate as a full-size drawing with every hour line, numeral, centre and foot mark, and a 100 mm scale bar.

Read the gnomon pattern 🔢 and a table 📋 of hour angles and edge coordinates.

Save 💾 the drawing to your photos 📸.

See 👀 the style height, substyle angle and nodus height for your design.

Check ✅ the finished dial

Record what your dial reads against the clock at different times of day.

Cyber Wolf fits how far the dial is turned and shows the residual before and after, with a chart 📊 of the checks.

Keep your designs

Save 💾 dials to a library 📚, load them back to the bench, rename, duplicate or delete them.

Show numerals in Arabic or Roman, the clock in 12 or 24 hours, and lengths in millimetres or inches.

A Learn 📖 section explains the formulas behind the bench.

Cyber Wolf is for makers, gardeners, teachers and anyone who wants to see 👀 how a sundial works before cutting metal or stone.
