The electronics board I used for my final project are the ones I made for Output device week and Networking and communication week.
I reported here the same documentation I wrote for those weeks.
I found the package for the voltage regulator in the fab's library :
and the package for the hall sensor in the Allegro's library :
The hall sensor we had is a ratiometric sensors that provide a voltage output proportional to the applied magnetic field (link).So I connect the output of the sensor to an ADC pin.
The pins for the bluetooth didn't need much attenction because I'll use SoftwareSerial,so I choosed 2 of the remaining available pins.

Actually the image above is the fixed version of the board.Previously I forgot to make this link :
And I saw it only when I was soldering the ATtiny 44.At the moment I fixed it whit a small piece of a copper wire :

Board master
Using Eagles as always,the designing process wasn't hard.I provided my board whit a Voltage regulator to be powered whit a 9V battery, and with an HallSensor because I want this board to calculate RPM of the tubines in the near future.I also provide exposed pins for the Bluetooth module I'll use for Networking and communicationI found the package for the voltage regulator in the fab's library :
