WEATHERMAN: Web Weather Forecaster

How many times have you asked yourself “What’s the weather going to be like today and over the next couple of days?” Then you have to turn on your computer, pull up a web page with a weather forecast, and wade through all the ads.  Yep, I know. Pretty tiring and time-consuming.

So now, the wait is over!

Introducing “Weatherman: Web Weather Forecaster“, the web-based three-day weather forecaster that provides all you ever wanted to know, right at your fingertips… literally!


Weatherman: Web Weather Forecaster showing today’s weather conditions. A low of 15 to a high of 19.6 degrees C, 53% humidity and a pressure of 1000mb, with overcast clouds and winds from the SSW at 1.9kph.

EQUATIO: Sidereal & Solar Clock

Meet EQUATIO: Sidereal & Solar Clock, my latest investigation of the measurement and perceptions of time. As so much of our life revolves around the 24-hour per day clock, it seems only obvious to question whether such precision and regularity is really natural? Or is our common measurement of time a man-made contrivance to insulate us from the chaos of the natural world?

Peering behind the curtain, we find strange things afoot!

So, I give you (roll of drums)… EQUATIO: Sidereal & Solar Clock… a bold attempt to re-appropriate “real time” and expose those “meanies” who control us through the imposition of order, symmetry and regularity (although at my age, the latter can be pretty important!).


EQUATIO Graphic: A revision to EQUATIO to display Local Mean Solar Time, Local Sidereal Time and Apparent Solar Time on a 192×64 pixel graphic display module. The difference in time between the Local Mean Solar Time and the Apparent Solar Time is the Equation of Time for 29 June 2015.


EQUATIO: Sidereal & Solar Clock showing current Eastern Daylight Time and today’s date (based on Mean Solar Time), Local Sidereal Time (LST) (based on time relative to the stars) and Apparent Solar Time (SOL) and this day’s Equation of Time (EOT) offset based on the actual observation of the sun.

Equatio: Sidereal & Solar Clock

EQUATIO: Sidereal & Solar Clock showing that the Apparent Solar Time currently lags Mean Solar Time (Eastern Daylight Time)  by 0.6 minutes (or 36 seconds).

“Equatio” was a word widely used in early astronomy as the difference between observed and averaged values. It seems quite apropos for this project.

Read on for a steamy exposé .  I NAME NAMES!

SUPERNUS, the Sky Globe

Meet SUPERNUS, the SKY GLOBE; a solar and lunar tracking device that will keep you looking up, night and day.

The Latin word “supernus” means “heavenly; celestial; of the gods” and beautifully describes my latest creation (muah ha ha).  SUPERNUS continuously calculates the azimuth and elevation of the sun in the sky (and at night, the moon) and displays its position as a beam of coloured light on the inside of an 8″ diameter frosted glass globe.


SUPERNUS, the Sky Globe. The image above was taken at 3:30AM on 9 June 2015.

SUPERNUS the Sky Globe

SUPERNUS the Sky Globe. The image was taken at around 17:30 on 8 June 2015 and shows the current position of the sun (at my location) in the sky (SSW and ~30% elevation)


SUPERNUS at 07:15 9 June 2015, with the sun in the ENE, elevation 20 deg.


SUPERNUS at 20:40 8 June 2015 with the sun just about to set in the WNW.


The sun “beam” moves in sympathy with the sun across the sky from East to West and at sunset is replaced by a moon beam that similarly traces the path of the moon across the globe. The position of the sun and moon take into consideration the user’s location and the the exact date and time and so accurately mimics how we see the passage of the sun and moon across the sky.

Heaven’s Above – Lunar & Solar Clock

Introducing “Heaven’s Above – Lunar and Solar Position Clock”, a real-time display of solar  position and lunar phase and position. In real-time, the display shows both the elevation and azimuth of the sun during the daytime, and the elevation, azimuth and phase of the moon at night. You need never feel alone again!

Heaven's Above

Heaven’s Above – Lunar and Solar Position Clock: showing the moon’s position – an elevation of 10 degrees at 125 degrees (SE) – taken at half-past midnight on 5 June 2015, and the the waning gibous moon phase. Moon rise, when the moon rises above the horizon, was at 11:52PM.

Heaven's Above - Lunar and Solar Position Clock

Heaven’s Above – Lunar and Solar Position Clock: showing the sun’s position – an elevation of 67 degrees in the cardinal direction of 145 degrees (just East of SSE, or ESSE) – just after noon on 5 June 2015.

Some of my most recent projects (including the two mechanical builds of the SolarTracer and the display of the Graphics LCD Analog Clock) have involved displaying in real-time the actual position of the sun in the sky – both its azimuth (cardinal position) and elevation above the horizon. I have now completed the more complex calculations for determining the same information for the moon and combined them into this project.
