Wiesbadener Kurier, 6th July 2001:
Heller's apparently futuristic acrylic glass and steel model works with absolute precision and enables us to trace the path of the sun across our planets.
Hessischer Rundfunk (Hessen Radio), 23th July, 2001:
He worked on his project for over 20 years. And it was worth it, for Hellers sundial can do so much more than the conventional sundial.
Frankfurter Allgemeine Zeitung (FAZ), 4th September, 2001:
Carlo Heller's sundial is a precision instrument, sensational, aesthetically pleasing, weather-proof and handcrafted in an unusually loving fashion: It brings a totally new perspective to the ancient idea of time measurement via the earth's orbit of the sun.
Westfälische Allgemeine Zeitung (WAZ), 27th September, 2001:
Carlo Heller, the experimenter from Wiesbaden, demonstrates the best in sundial construction. Behind his precision instrument can be found an enormous amount of astronomical knowledge and attention to detail.
Panorama on 18th October 2001:
A small mirror and a laser-marked sphere. The re-birth of the ancient sundial. But much more accurate.
Classic clocks – Journal for friends of classic time instruments, April 2002:
The Helios sundial operates absolutely precisely according to a unique new principle, for which the patent is currently pending.
natur & kosmos, May 2002
The mechanical engineer has created a precision instrument with which he has revolutionised time measurement via the movement of the earth.
Nürnberger Zeitung (Nuremburg Newspaper), 29th May, 2002
... an invention which caused great excitement in sundial fan circles.
ALL ZEIT, Magazine of the Wilhelm-Foerster-Star Watchers, Berlin e.V., June 2002
The design in stainless steel and acrylic glass makes the sundial an attractive ornament for garden or terrace.
Mitteldeutsche Zeitung (Newspaper for Central Germany), 8th June, 2002
Two additional models will appear on the market from July. Instead of today's date, the „Zodiacus“ sundial shows the position of the sun in the astrological signs of the zodiac. The „Meridiana“ sundial shows solar time, the sun's height and the meridian transit of the world's capital cities. So it's sunny times ahead for fans of this type of time measurement.
ARMBANDUHREN (Watches), June/July 2002
Each Helios sundial is unique because its mirror optics are individually calculated specific to each location. But its intricate workmanship and of course its fascinating shape ... make the sundial an attraction for any sun terrace.
P.M. Peter Moosleitners Magazine – The modern world of knowledge, July 2002
"In 100 years, our chronometer is only 30 seconds wrong" promises the inventor
"- in comparison, quartz clocks would have an error margin of one second per week."
zuhause wohnen (Living at Home), July 2002
"The decorative highlight for your garden: a top-class sundial".
3sat, Tips and Trends for the Home, 20th July 2002 (TV)
"A sundial for individualists, technically and aesthetically perfect".
3sat, nano, 9th September 2002 (TV)
"And there is nothing which does not originate from Heller’s know-how: from the prototype to the laser-controlled manufacturing system, constructed by the man himself."
Handelsblatt, 10th September 2002
"In order to accurately display the time at the installed position, each sundial is specially calculated and manufactured for the selected location.
3sat, The Inventor, 28th September 2002 (TV)
"Heller is a perfectionist through and through. The extreme accuracy of his sundial would not have been possible without its ambitious construction. Just the whole mechanism for installing the sundial is a technical masterpiece."
Gnomonica Italiana, October 2002
"The sundial ...is really an instrument of great precision in both its mechanical construction and its functioning, it unites simple design with an elegance of lines".
British Sundial Society Bulletin, December 2002
"...an interesting type of sundial, called by its designer 'Helios'"
intermediair (Dutch magazine), 3rd April, 2003:
Why develop a sundial in the age of bargain quartz clocks ? "Because in this fast age people want to go back to their roots", says the mechanical engineer Carlo Heller. "To the cosmic clock, from which our timekeeping originates."
Basler Zeitung (special edition Clocks & Jewellry), 3rd April, 2003
The "Helios" sundial created by the German engineer Carlo Heller impressively combines an aesthetic objet d'art and a universal measuring instrument...the noble exterior is simply the result of functionality and the uncompromising finish of a well-conceived instrument, which could only be achieved by a hard-bitten perfectionist.
Frankfurter Rundschau, 14th May, 2003:
On a sunny day in 1980, Carlo Heller pursued a dot of light. A mirror projected the sunlight onto the ceiling in his parents' house in Wiesbaden. As time progressed, the luminous point crept across the ceiling. 21-year old Heller saw this as a challenge which has characterized his life: He tried to calculate in advance where the dot would land..."The thought that earth and sun are turning like two enormous cogs in the workings of a clock has continued to fascinated me", says Heller...
German Society for Chronometrics (DGC), annual report 2003 (contribution from Dr. S. Wetzel, Bern):
The HELIOS sundial represents an important and valuable step in sundial development. For the first time, it illustrates the connection to the sub-solar point with the required level of clarity.
Gnominicas Societas Austriaca (GSA), Circular December 2003 (contribution by Karl Schwarzinger):
Several young gnomonicians are in the process of taking position among the ranks of the great, by succeeding in creating something totally new in the gnomonics field with their inventions. The engineer Carlo Heller is one of these pioneers.
CLOCKS Magazine UK, August 2005 (contribution by Christopher Daniel, chairman of the British Sundial Society):
This sundial (MONDO) is an unusually elegant example of German precision engineering, which would look good in almost any garden or any chosen position.
