How to make a acceleration logger in a Nokia 3310 cellular phone.

I will use it to measure the forces on roller coasters :)

Step 1: Tools You Need

Some tools you might need:

nokia 3310
soldering iron
T6 screwdriver
material to make PCB:s or a "board house"
some materials to mount on the PCB:s
a stationary drill and some mill and drill bits
a spare nokia 3310 lcd if you brake it :(
a microSD card
uALFAT chip from ghielectronics to handle the microSD card
Microchip PICkit2 to program the uP
External sensor, reused from a previous project

Step 2: Dismantle the Phone

Begin to dismantle the phone and reuse the part you need (shell, frame, battery, buzzer and battery connector).

Step 3: Make Some PCB:s

Make the PCB:s your self or let a "Board house" do them for you.

The file for the PCB:s are right here:

Step 4: Finnish the PCB:s

Solder on all components on the PCB:s and make some modification :( .

Step 5: Mill and Drill

Mill and drill the shell and frame to make room for everything new :)

Step 6: Reassembly

Reassembly the unit again. Make sure that everything fits. And finally, connect the battery and program the unit. The software is not really completed, bugs to fix :(
