gresis, ovaj, gresis silno sinko!

Hints:
"First of all, be careful not to exchange the ultrasonic transmitter with the receiver: they look very similar, and I suggest you to mark them very clearly from the moment you buy them."
lepo ti kaze ovde da su prijemni i predajni elementi slicni i da ih ne pobrkash
"During setup, place the ultrasonic transducers over a soft surface, near the border of a table, 10 cm apart of each other pointing outwards the table. Then adjust TR1 and TR2 using a rigid surface (for example a metal sheet) placed in front of sensors, at a variable distance."
ovde ti lepo kaze kako i gde da postavis pretvarace: na meku podlogu na ivici stola da su okrenuti van stola i da koristis tablu za podesavanje. tabla je naravno za odbijanje ultrazvuka.
"Do not choose an enclosure too small: always separate the transducers by 7-10 cm and plenty of sound-absorbing material, otherwise the receiver will reveal the direct sound instead of the reflected one."
ovde ti kaze da ti ni kutija ne bude premala i da senzori budu dovoljno razmaknuti
i da stavis zvucno-upijajuci materijal okolo
"The same applies if the sound travels through a rigid fixture, so it is a good idea to fix them with separated supports."
ovde napominje da se (ultra)zvuk prostire i kroz nosac pa preporucuje odvojene nosace da bi eliminisao lazni signal.
"And remember not to mount the tranducers exposed to direct sunlight nor rain."
ovo znas. nema na sunce i nema na kishu izlaganja.
