What can 62 LEGO bricks build? An equatorial sundial. A recent dial building project demonstrates a very nice looking sundial dial built from regular LEGO elements. The design is a classic equatorial sundial using a central north-pointing rod gnomon with shadow cast only hourly segments tilted at 15 degree increments. The base swivels such that it can be adjusted for any latitude.
The building blocks use 1xN plates placed side by side on the underside of a 1x4x5 arch, creating the hourly progression of 15 degree tilted tiles. In the design shown, two blue plates in the center bracket the noon mark. Outer blue plates indicate 6am and 6pm. All you need to do is paste on the hour numerals.

It appears that a number of different sundials can be created using LEGO tiles. A comment on the shown design is that "after some experimenting, I think the base needs to be extended by two stud lengths. The center of gravity shifts a little too far when the dial is adjusted for lower latitudes. It still stands, but is tippy."

In fact, there is a whole world of LEGO sundials. Check out http://62bricks.com/category/sundials where you'll find more equatorial sundials, a vertical east-west sundial, and a polar dial. It's amazing what you can do with LEGOS

Cosmic Room with Solar Analemma |
|
|
Posted: Sunday, 12 February 2012 15:11 |
 Ruben Nohuitol of Queretaro, Mexico has a unique solarium or “cosmic room” to observe the rays of the sun throughout the year. He has patiently constructed a wonderful time-lapse video following the sun every day at 12:45 pm. His construction has a vertical meridiana beam of light descending and then ascending the wall as time passes throughout the year. A second sky-light gnomon creates a classical analemma on the floor.
He has a number of videos well worth watching: Sunset at the foot of the pyramid of Pueblito, Mexico, diurnal beams at summer and winter solstices, the equinox and more. Visit Ruben Nohuitol’s photos and web-cam videos at: www.ruben.mx

Sundials of Downton Abbey |
|
|
Posted: Saturday, 21 January 2012 16:15 |
Many have been following the Primetime Emmy Award winning series Downton Abbey on PBS. This British World War I period drama was filmed on location at Highclere Castle in Hampshire, which represents the fictional Downton Abbey. Many outdoor scenes were filmed in the village of Bampton, Oxfordshire. (See http://en.wikipedia.org/wiki/Downton_Abbey )
As you follow the lives of aristocrats and servants in this acclaimed series, keep an eye out for sundials. Attached are photos of three sundials noticed by NASS members. Want to search for yourself? The full episodes of series #1 are available at PBS.org and the new series #2 is just starting.

Chatham Square Dial Vandalized - Again |
|
|
Posted: Friday, 20 January 2012 22:15 |
Lesley Conn reports in the Savannah Morning News the restoration of its vandalized sundial. This is no college prank, but a malicious and repetitive attack on the Louis B. Toomer sundial in Chatham Square in the historic district of Savannah, Georgia. Conn reports that “City officials are adding new elements to the repair process – a public plea for help and a reminder to the monument marauder that destruction of public property is a felony. They made their case Tuesday after sealing a new sundial to the stone base.”
The 8 inch diameter sundial has a face of bronze with Roman numeral hours delineated every 15 minutes and delicately shaped brass gnomon. It sits atop a concrete pedestal with indented lettering stating “In Memory of Louis Burke Toomer, Registrar of U.S. Treasury, 1953-1956, Founder and President of Carver State Bank, 1927-1961”. ...” If the vandalism is a demonstration of “occupy wall street” it is very misplaced. City conservation coordinator Larry Fagley says “We’ve welded it, we’ve drilled holes in it to shoot more epoxy into it, and within a week, they’ve kicked it off…”

Sundial WebCam In Action |
|
|
Posted: Sunday, 11 December 2011 22:28 |

Want to watch a sundial in action? Professor Woodruff Sullivan and Ian Smith at the University of Washington in Seattle have just launched an active webcam of the University’s large vertical declining sundial on the side of the Physics and Astronomy building. The webcam image is updated once per minute day and night. “we know that some of you will want to stare at it for hours on end (or at least bookmark it….”
Their website has many features including the first two time-lapse movies of the giant sundial showing the all-day shadow on the summer solstice and on the autumn equinox. More time lapse videos will be presented during the months that come. In the near future they will improve the present camera with higher-resolution and greater reliability.
A flurry of sundial webcams existed in 2004-05 when the EarthDial Project, the invention of Bill Nye and Woody Sullivan, was run under the auspices of The Planetary Society. The Project, with a motto Two Worlds, One Sun was run in conjunction with the MarsDial Project, which involved the Mars Exploration Rovers Spirit and Opportunity, each of which landed on Mars in 2004 with a small calibration target turned into a Mars sundial on its deck. People around the world were urged to build sundials of a standard design and display them to the world using a webcam. Click Here to See Time Lapse Movies of Some of These Dials. A new Mars sundial will arrive red at the red planet next August onboard Curiosity.
Take a look at the new webcam at http://sunny.astro.washington.edu

Dial "Down Under" Acquired by Historical Museum |
|
|
Posted: Monday, 05 December 2011 06:43 |
  The words “sundial” and “convict” are not often used in the same context, but that is the situation in Port Macquarie, Australia when a vintage sundial made around 1840 was put on permanent display at the Port Macquarie Historical Museum. The dial was made by colonial engraver Raphael Clint and was once owned by Danial Cohen, who, convicted in 1830 of receiving stolen property in Lancaster, was sent to Port Macquarie, a penal colony at the time.
