i should give my old desk "second life" soon. thanks for the inspiration brother.

i usually make my USB cable myself w/ coax cable for high quality serial communication

Yup, it is possible. because serial cable consist of Vcc, GND, Data +, and Data - . Below is the pinout diagram of cable USB A and USB B.

nope, sqlite for the database that could be access easily from server but .sdv datalog require further code that affect in its simplicity.

thanks kooth, your welcome!

yup you could do it. check this nice tutorial link from adafruit belowhttps://learn.adafruit.com/adafruit-arduino-lesson-11-lcd-displays-1?view=all

check the program again dude, sometimes the program a little tricky. for record data, yup you could do it. check the link below and you should be finehttps://learn.adafruit.com/adafruit-micro-sd-breakout-board-card-tutorial?view=all

include the library dude. you could do it in sketch->include library. hope this help!

yup it's the bug. i tried myself.

picocom /dev/ttyUSB0 -b 9600 -r -l

not really, you could use picocom to start the communication automatically. But, it is recommended to install arduino ide so you could troubleshoot your code.

you could find it in ebay, amazon, etc. but actually you could make your own sensor. Both sensor use capacity sensor principle.

nuvoton is a rare board nowadays. you could find similiar ARM type board like STM32. But if you really want it so bad you could ship it directly from taiwan. just contact here http://www.nuvoton.com/hq/contact-us/?__locale=en
