 '''ATTENTION''': The building of the little device is finished. Important: The pumping of the level shifter consumes a lot of energy, so it is definitely necessary to provide 3.3 V. There are MAX232 chips which work with 5V. They are not suited for this kind of project even if they are cheaper (1 Euro). The [http://produkt.conrad.de/45973183/max-3232-cse-16-so.htm 3.3V version chip (MAX3232)] costs about 5 Euro. Make sure you buy the 3.3V variant!! Thanks to Thomas Schäfer who gave this hint!
