A device that measures the ambient temperature in the environment in which it is located. And displays it on the screen.

Artistic description

Plant-like structures. Display like blossom. Bottom woodblock aged with brushing with a wire brush and oxidation solution (steel wool + vingar).


When the number to display changes it plays short animation.

Technical description

The first goal was to test an easier way to connect 7-segs and shift registers.
Main CPU, Arduino pro mini, uses thermistor to calculate temperature. Uses two different algorithms for this: Steinhart-hart equation and Beta model equation.
The display consists of two seven-segment displays. Drived by two 74HC595 shift registers. Which is connected to the seven-segment displays in a non-traditional way.This makes the construction easier.

Readin data

The simplest way to read serial data is to use Miniterm:

Also, I have made two Python scripts. read.py and simple GUI app gui.py. What display average temperature.


Lovely letters


produced in the second half of the 9th century, possibly in northern France. Following the Psalms, which were heavily annotated with commentaries in later centuries (mainly the 14th and 15th centuries), the Psalter is followed by the Canticles as well as a fragment of a Litany of the Saints not produced at St. Gallen. The beautifully illuminated initial capital of the first Psalm (Beatus vir) on page 1 is strongly influenced by Irish models.


Collection of liturgical works,

containing texts from the 9th to 12th centuries and an illustration of Pacificus of Verona’s star clock.


The Wolfcoz Psalter

– one of St. Gallen’s earliest examples of illuminated initials of the highest quality.


Depiction of women in heraldry

St. Gall Abbot Ulrich Rösch’s (1462-1491) book of heraldry, containing 1,626 coats of arms of prominent people from the laity and the clergy, mostly from the southern region of Germany. This heraldic book was probably prepared in the Heidelberg workshop of Hans Ingeram for an unknown customer from the area between the Neckar River and the Upper Rhine. In the 1480s St. Gall Abbot Ulrich Rösch purchased the volume and had numerous coats of arms from Swiss and German border areas added in the back pages; these were drawn by Winterthur artist Hans Haggenberg. One of the most important heraldic record books of the 15th century.
