Microcontroller Prototypes with Arduino and a 3D Printer

A review of Eupholidoptera (Orthoptera, Tettigoniidae) from Crete, Gavdos, Gavdopoula, and Andikithira

“…Not all sampling stations were active for the entire duration of the study. In total, 24 stations around Crete were sampled ( Bolanakis 2019 ; Bolanakis and Trichas 2019 ). The fermenting traps consisted of plastic water bottles (1.5 L) with an entrance hole in the top half containing a mix of alcoholic ingredients, sugars and some preservative (as in Galford 1980 ; Nageleisen and Bouget 2009 ).…”

“…The fermenting traps consisted of plastic water bottles (1.5 L) with an entrance hole in the top half containing a mix of alcoholic ingredients, sugars and some preservative (as in Galford 1980 ; Nageleisen and Bouget 2009 ). The mix that lured the Eupholidoptera specimens consisted of vinegar, sugar, salt, alcohol, yeast, glucose and rotten banana ( Bolanakis 2019 ). Ingredients were stirred manually until the sugar and salt were dissolved and 0.2–0.3 L of the mix was poured in each bottle.…”

“…Bottles were hanged inside the foliage and tied on tree or bush branches with a string. Trap stations were revisited every one or two months to replace traps and take the collected samples, after adding pure alcohol, to the laboratory ( Bolanakis 2019 ). Eupholidoptera were collected in fermenting traps at nine different locations.…”

FDM 3D Printer based on Raspberry Pi

“…3D printers are speedier, more economical, and easier to use than previous industrial technologies. The use of 3D printers enables the production of complex, large, protruding, and overlapping pieces [7]. There are a variety of mechanical and physical criteria for the created products that 3D printers make.…”

“…The finished product from the printer is an identical reproduction of the original. The cost of the printer is not excessive and becomes less expensive for complex shapes [7]. The following are 3D printer drawbacks: Inexpensive printing costs [1] and the printing procedure is slow and might take days or even weeks depending on the size of the product.…”
